Concrete Types

Cement and unquestionable are everyplace between us. But, do you know that there are many kinds of certain based on their custom? If not, then this article is a must read for you.
In today’s world, our city can be called ‘jungles of certain’. This wonder cloth is everywhere around us. Basically, clear is a material used for expression purpose and consists of Portland cement fused with strengthening material like aggregate (gravel, granite, limestone, sand), fly ash and slag cement, water, and ingredients if any. There are many rather unquestionable mixes based on the various factors, like proportion of aggregate, production procedure, usage, etc.. Here is a list of the most commonly found exact types but ahead of that a brief about unquestionable.
Different Characters of Concret
Concrete Type Description
Cement Concrete This is the most widely used type of clear and is made by mixing Hydraulic cement with sand, fine mortar and water. The symmetry of cement, sand and mortar may vary from 1:1:2 (counted the best quality mixture) to 1:3:6 (a inferiority mixture mostly used for exact filling).
Reinforced or Structural Concrete In this type, light source cement certain is reinforced with metal rods to impart awful load bearing capacity. Concrete of such quality works for those structures that have to bear large weights like radios beam and pillars. If reinforced concrete is constructed of in its compact form using stone total, it has comparatively higher density (about 2.4) which further heightens its great forcefulness.
Plain Mass Concrete This type of unquestionable is not beefed up by any reenforcements. It is mainly used in structures like thickeners oundations, certain types of exact slabs, dams, and exact cube retaining walls on bridges circuit and flyovers. This type may also be called non-reinforced clear.
Lean Concrete It is a plain type of unquestionable with a larger aggregate to cement ratio than structural certain. Lean unquestionable is mainly used for filling and not structural tariffs, as it has low weight bearing strength.
Prestressed Concrete It is a type of structural exact which is compressed using high pressure in those parts which are subjected to extreme tensile forces so that the unquestionable is not in a state of tension when actually under the workload.
Vacuum Concrete Vacuum exact contains high tide content which allows sufficient ease while working and placing it into complicated molds or while doing extended reenforcement. This unquestionable is then subjected to a vacuum that ensures that no excess amounts of water is retained, which successively ensures a stronger certain on hardening.
Cast in situ Cast in Situ Concrete The cast in situ certain is just deposited in its desired position to harden. This is perhaps the most common method used in mental synthesis of unquestionable roads where the certain is directly deposited on the ground.
Precast Concrete These exact blocks are placed in separate molds, under controlled conditions, to harden and whenever needed, transported to the site for final hard on. This operation gives superiority unquestionable castings and that too at a comparatively low cost. This exact is used for paving slabs, road channels, kerbs, lintels, bricks, fence posts, bridge beams etc. xEOL. Pumped Concrete This exact is transported through pipes from the mixer to where it is deposited. The certain is prepared by acquiting it from the mixer into a hopper which feeds it to a pump which pushes it through a pipe. Standard pipes are 100 or 150 mm in diameter and can easily pump this unquestionable over horizontal aloofnesses of 650 m or vertical statures of 50 m, or permutations of these lengths.
Spun Concrete This type of exact is used for the production of pipes and vessels with curved surfaces. The process of fabricating involves feeding fairly dry certain into a rotating cylindrical molds. This mix is flung facing the curved wall by centrifugal action to manufacture a dense hard impermeable piped structure.
Concrete : How to Make
The most popular way of making unquestionable is using Portland cement and mixing mineral aggregates and water with it. Concrete solidifies quickly as the cement components hydrate and glues all the added aggregate together. The clear thus formed has high compressive strength and it is generally used for making pavements, gates, fences, walls, slabs and more. External additives and stabilizers are added to the unquestionable to impart it with some desired characteristics. In earlier times, certain would often be referred to as liquid stone. Here are some of the major unquestionable types.
Ready Mixed Concrete Ready mixed certain is created at mixing plants and presented to the building site in specially designed vehicles. The vehicle has a large rotating drum in which the clear unceasingly mixes until it is delivered to the site. The mix stipulation is first decided by the supplier and the contractor, prior to delivery.
High Denseness Concrete High de.

Wallpaper Paste

Wallpaper paste is the adhesive that makes it possible to secure wallpaper to a surface securely. Over the years, a number of different types of wallpaper paste have been developed for use in wallpaper hanging. Here are a few of the options that are available to the wallpaper hanger when it is time to change the look of a space with the use of a wall covering.
Clay based vinyl adhesive is a popular option in wallpaper paste today. As a mixture that will work with vinyl as well as paper wall covering, this type of wallpaper adhesive chinafooding is composed of clay, dextrin, and minute quantities of biocides and cellulose. Generally, the product is available in one and five gallon pails. Clay adhesives are known for their lower water content, and provide excellent tacking for any wall coverings that are a slightly heavier grade, such as embossed wallpaper.
Wheat paste is one of the oldest forms of wallpaper paste. Considered to be the most reliable form of thickeners wallpaper glue prior to the development of vinyl wall coverings in the middle of the 20th century, wheat paste continues to be popular with many experts. The paste compound is normally sold in bags, and can be mixed just prior to the application. Brushes are used to spread the prepared compound on the back of a section of wallpaper just prior to hanging. Generally, this form of wallpaper paste allows enough time to smooth out creases and work out bubbles in the paper before the paste sets.
Cellulose Methyl Cellulose ether is a form of wallpaper paste that has thickening qualities as well as being an excellent adhesive. The compound works well when applied to wood or sheet rock. One drawback is that cellulose methyl ether has the highest water content of any type of wallpaper paste, which can make the application much more involved. The paste works best with wallpaper products that are somewhat porous, such as grass cloth or silk.

Uses of Sodium Alginate in Other Industries

It is so amazing how salt derivatives and natural amylase carbohydrates contribute to a variety of industries all over the world. What are we talking about? We are dealing with a powerful compound known as sodium alginate.
Sodium alginate, derived from alginates which are found in the cell walls of brown seaweed, are very helpful compounds. It is not only popular in the medical, textile, printing, and food additives industries but other industries take advantage of it as well. It is so versatile that welding, casting, cosmetic, and papermaking industries benefit from it.
Used as ingredient for papermaking
Papermaking typically includes Rosin paper pulp. Sodium alginate has become a better and probably cheaper substitute. It functions to make the paper’s surface smoother and regulates printing ink and wax absorption. It can also make paper pliable and tough.
Used for making Cosmetic products
Some cosmetic companies take advantage of sodium alginate. They typically use it to help retain moisture in cosmetics. Shampoo companies use it too as a bubble stabilizer and thickeners. Skin care products use it as an emulsion stabilizer. Sodium alginate is also found in toothpastes as a bonding agent. Since sodium alginate easily absorbs waters many facial cosmetic products such as facial masks use it as a filmogen. It can help hydrate, soothe, and soften skin.
Used with electrode coating material for welding
Welding coating can be humidified when powder used for welding or electrode coating material is coated together with sodium alginate. The compound can endow the welding coating with the right plasticity while the extrusion process in ongoing. Moreover, it can also help minimize splashes produced while welding because the alginate makes it easier to decompose into ash.
Sodium alginate is without doubt a useful resource. Being used in a series of industries makes it an important ingredient in major processed food products, medications and other industries. Alginates can be purchased in powder or crystal form and can be ordered from many Asian companies. This light yellow water soluble compound is available in paper grade, pharma grade, textile grade, tech grade, food grade, and cosmetic grade.
Whatever industry uses sodium alginate they are surely satisfied with its amazing benefits. From health down to welding, it has greatly proven itself to be an effective component of the sea. Think about it – an amylase from seaweed can do wonders to the body!

Gum Arabic

Gum arabic is obtained from acacia trees. Also known as gum acacia, gum arabic is a natural gum. Why is it called natural gum? Well, because it is made using the hardened sap obtained from Acacia Seyal and Acacia Senegal, the two species of the acacia tree. Other than gum acacia, it is also known as meska, char goond and chaar gund. Although, West Asia and Arabia were the regions where the wild trees were cultivated for the production of gum arabic, it is now widely harvested in places including Senegal, Somalia, Sahel and Sudan. While it is produced in African Sahel in huge quantities for commercial purposes, it is still used traditionally in places such as the Middle East.
Gum arabic is a food additive and is edible as it is a mix of glycoproteins and polysaccharides. Gun arabic powder or Xanthan gum is mostly used in confectioneries as a stabilizer, thickeners or even for sugar crystallization. Food additives are identified with number codes called E numbers and the number code for gum arabic is E414. Not just gum arabic is edible but it has numerous other uses and it is used by a variety of industries other than the food industry.
Gum Arabic Uses
Food Products
As mentioned earlier, gum arabic has properties of a binder or a glue that is edible for human beings. This is because it is a mixture of proteins and saccharides. Now although it may be edible, it have a toxic effect which will be discussed later in the article while discussing the possible gum arabic side effects. To name a few food items in which gum arabic is used as a binder would include marshmallows, syrups and candies. Xanthan gum uses can also be referred to know more about xanthan, another type of food additives used in many products.
Photography
Similar to painting and printing, it is also used in a photography technique and the name of the process is gum bichromate photography. In this process to produce a colored photographic emulsion; gum arabic is mixed with other components including ammonia and pigment. As in case of the water paints, the pigment binds into the paper of the final print.
Painting
Gum arabic is a traditional binder used in making watercolors or water paints such as the gouaches. This is because gum arabic easily dissolves in water and gels well with the water and then in the process of drying, the color pigment binds into the paper surface. Heard of one of the methods of printing called lithography? Gum arabic is one of the main ingredients used in this ancient printing method.
Other Uses
Besides these, gum arabic is also used as a soluble binder in producing fireworks or in pyrotechnic devices, in inks, cosmetics, shoe polish, incense cones, postage stamps and of course glues.
While some research reports suggest that gum arabic can be used as an alternative medicine to lower cholesterol levels because of its properties, there are arguments that it does not due to inconsistent and strangely opposite results in certain cases.
Some of the gum arabic substitutes include guar gum, locust bean gum, carrageenan and gum tragacanth. Studies suggest that high dosage of dietary gum arabic is the possibility of resulting in any side effect such as stomach upsets or irritations. Although if the person is allergic to acacia they may experience skin reactions or even asthma attacks in certain cases. Many of the food products contain xanthan gum so you might be interested in knowing Xanthan gum side effects as well. I hope this article on gum arabic has given you substantial information on its nature, uses and side effects.

What’s Xanthan Gum

Xanthan gum and guar gum are the most common food additives used to make gluten free recipes. What is xanthan gum?Xanthan gum is one of the most common food additives. It is widely used as a thickening and stabilizing agent in the production of cosmetics and food items. Xanthan gum is derived from corn sugar. It is known for its excellent binding properties. As a food additive, it does not affect the color and flavor of the food.
How is Xanthan Gum Made
Xanthan gum is made by mixing corn sugar and bacteria called Xanthomonas campestris. The name ‘xanthan’ is derived from the name of the bacteria ‘Xanthomonas’ that are used to bring about fermentation of corn syrup. You don’t get corn syrup just by pressing corn kernels. The pulpy cornstarch has to be separated from corn kernels. Cornstarch is broken down into glucose when you add natural enzymes to it. You can obtain corn syrup by heating the sugars. Xanthan gum is nothing but fermented corn sugar polysaccharide. The bacteria Xanthomonas campestris, used to ferment corn sugars, help transform the complex molecules of corn sugar into simple molecules. Then a colorless viscous matter finally obtained is known as xanthan gum. Properties of xanthan gum and that of cornstarch are quite similar. The colorless slime or xanthan gum is used as a stabilizing or thickening agent in various food products or cosmetics.
Uses and Properties of Xanthan Gum
Xanthan gum plays an important role in offering smooth texture to ice creams. It helps prevent formation of ice crystals in ice creams. In salad dressings, sauces and pastry fillings, it acts as a stabilizing agent. In food industry, it is mainly used as a substitute for egg yolk. It is commercially used to produce egg substitutes that contain egg white. It acts as a fat substitute. It keeps you satiated when added to no-fat, or low fat dairy products. It also exhibits emulsifying properties of egg yolk. Xanthan gum is also used for thickening of soups.
Xanthan gum comes in liquid or powder form. Its properties are not affected by heat and it gets easily dissolved in hot or cold water. It is mainly used in the production of gluten free food products. Bread, cake, pasta, which contain xanthan gum as an ingredient, give a nice feel while eating. Xanthan gum thus, acts as a wheat gluten substitute in various flour-based food products. People with gluten allergy and those diagnosed with celiac disease can enjoy food products with xanthan gum.
What is Guar Gum
Some people are allergic to corn and corn-based products like xanthan gum. They can enjoy food products that contain guar gum, gum arabic, locust bean gum, gum tragacanth or carrageenan. Guar gum is a kind of natural food thickeners. Compared to cornstarch, very small amount of guar gum is required when used as a thickening agent. It is used in ice-creams, puddings, soups, etc. Guar gum is a very good binder and plasticizer. It is used to produce various processed foods that have characteristic creamy textures. It was also used to produce diet pills that were meant to create a sense of fullness. The FDA has banned the use of guar gum in diet pills or diet shakes, as this has led to stomach problems. Guar gum is obtained from guar seeds. Guar belongs to the group of important ‘cash crops’ of Pakistan and north India.
Those who are interested in baking and want to use xanthan gum as a binding agent, can order it online. Or they can buy it from a health food store or organic food store. You should look for it in gluten-free sections. You can always find xanthan gum in GNC and Whole Foods.

Side Effects Of Xanthan Gum

Xanthan gum is a thickening agent named after the bacteria used to make it through fermentation. This common bacterium is the same culprit that causes your cauliflower to turn black when rotting. Although you would not eat rotting cauliflower, xanthan gum is generally safe and only causes mild irritations in some people. Guar gum and cellulose gel are common alternatives to use as thickening agents. Since celiac disease and gluten-free diets are becoming more commonplace, xanthan gum is also being used in more baked products to replace gluten.
Allergic Reaction
Manufacturers are not required to list what food the Xanthomonas capestris bacteria eat during production. If you are allergic to any vegetation including soy and corn, you may want to seek an alternative thickening agent. If you only have a slight allergy, you may want to test several individual brands to determine which ones produce the fewest side effects. Allergic reactions can produce severe symptoms, such as difficulty breathing. If you notice swelling or rash developing, talk to your doctor.
Gastrointestinal Irritability
The most common side effects of xanthan gum are gas and bloating. If you ingest a large quantity of xanthan gum, you may experience severe abdominal pain from gas buildup in your intestines. A clinical study on the effects of food thickeners xanthan gum on dogs was completed by the World Health Organization. In this study, dogs were fed large amounts of pure xanthan gum and experienced weight loss and chronic diarrhea. A typical 150-lb. person would have to consume over 60 g of xanthan gum daily to replicate this study. Typically, on a gluten-free diet you would consume an average of 0.5 to 4 g of xanthan gum per day from products. No human trials have been done to determine if normal dietary consumption of xanthan gum produces any gastrointestinal effects except gas.
Respiratory Distress
Xanthan gum can be purchased in a powdered form for use in your kitchen. This low-density, fine powder has the ability to create a cloud in the air when being handled roughly. Inhaling xanthan gum may allow it to accumulate in your lungs, according to the World Health Organization. Eventually, xanthan gum may induce respiratory distress by making absorption of oxygen in your lungs difficult. The Xanthan Gum website reports that industrial workers who produce xanthan gum have experienced respiratory problems. You should be careful when handling food additives xanthan gum and try to be gentle when adding it to your recipes. Inhaling small amounts should not cause any problems; however, if you believe you are experiencing any breathing difficulties, consult your doctor.

What Is The Sodium Alginate?

Function
An algae-extracted gelling agent, sodium alginate is used in molecular gastronomy in association with calcium salts for the basic spherification and reverse-spherification processes, whether to make small caviar-like pearls or large ravioles.
Origin
The properties of sodium alginate were studied for the first time in 1881 by English chemist ECC Stanford. He had at the time extracted a viscous liquid from brown seaweed of the Laminaria species, with an alkaline solution. He called this product “Algin”, a term still commonly used to describe sodium alginate.
Sodium alginate is therefore a salt extracted from the viscous liquid from the cell wall of brown algae. Its natural function is to increase the flexibility of the algae. Thus, algae developing in troubled waters generally have larger alginate content than those growing in calm waters.
Although all brown algae can be a source of alginate, variations in their chemical structure influence the properties of the final product. Different species are therefore harvested according to the purposes for which they are intended and the two most popular are the macrocystis pyrifera of California and the ascophyllum nodosum, grown in the North Atlantic.
Industry applications
Approximately 50% of the world production of alginate is used by the textile industry where the additive is used as an ink thickener in the printing process.
For its part, the food processing industry uses 30%. The thickening properties of alginate are used for example in sauces, syrups and some products containing milk. It is also used as a stabilizer and anti-settling agent in ice cream and milkshakes, as well as acting as a stabilizer and emulsifier in some salad dressings.
The rest of the production is mainly directed towards the pharmaceutical and pulp and paper industries.
Properties
The uses of sodium alginate take advantage of two special properties it has. On the one hand, once dissolved in an aqueous solution, sodium alginate has the property of thickening the preparation and increasing the viscosity. On the other hand, when brought into contact with a calcium solution, it forms a gel. This gelling occurs through a cold process, as opposed to the formation of agar-agar gels.
Creative cooking applications
Possible applications of sodium alginate in the kitchen were mostly made known with the popularization of the spherification process by Catalan chef Ferran Adria, of the elBulli restaurant.
By dissolving a small amount of food additives sodium alginate in a chosen alimentary liquid, spheres with jellied edges and a liquid interior can be fashioned. The liquid simply has to be delicately droped in a calcium solution. Alginate and calcium will join to form a gelatinous wall around the liquid sphere thus created so that the spheres will burst in the mouth. They can be served hot or cold, in a mound that reminds of caviar or dispersed in a cocktail.
Tips and tricks
Fast Service
The gel film that forms instantly on contact with the calcium solution will thicken towards the middle of the spheres until they are fully gelled. It is therefore preferable not to let them rest if a liquid interior is desired.
Alginate Solution Disposal
As sodium alginate reacts to calcium, do not pour the excess alginate gel down the sink to avoid blockage. Choose instead the trash or the toilet, which has a larger pipe.
Eliminating Air Bubbles
Air bubbles are often trapped in the preparation during dissolution of the alginate. In order to prevent such bubbles from complicating the spherification process, it may be necessary to let the preparation settle for a few hours.
Uniformity and Roundness of the Pearls
For “caviar” that is very round and uniform, position your pipette or syringe parallel to the surface of the calcium bath. The flow of drops will thus be better controlled and the pearls will be round and well defined.
It is also possible to dissolve the alginate a few hours ahead of time in a small amount of water. The air bubbles will be evacuated during the resting period and the solution will mix well with most preparations. Thus prepared, the spherification solution will not contain any air bubbles.
Choosing a Calcium Salt
It is preferable to use calcium lactate or calcium gluconolactate for all types of spherification rather than calcium chloride. The latter tends to give the pearls a bitter taste, even after being rinsed.
Correcting pH
Acidic solutions such as lemon juice and white vinegar can not be spherified because sodium alginate is not soluble at a pH below 3.7. It is however possible to add sodium citrate to reduce the solution’s acidity to an ideal pH of about 5 and so allow spherification. For cons, the taste of the final preparation will be altered by sodium citrate.

Carrageenans Application Function

Carrageenans (E407) are a family of linear, sulphated polysaccharides extracted from red seaweeds. The name is derived from a type of seaweed that is abundant along the Irish coastline near the village of Carrageenan. Gelatinous extracts of carrageen seaweed (also known as Irish moss) have been used as food additives for hundreds of years.
There are three main commercial classes of carrageenan:
Kappa – strong, rigid gels. Produced from Kappaphycus cottonii
Iota – soft gels. Produced from Eucheuma spinosum
Lambda – form gels when mixed with proteins rather than water, used to thicken dairy products. The most common source is Gigartina from Southern Europe.
All are soluble in hot water, but in cold water only the Lambda form (and the sodium salts of the other two) are soluble.
When used in foodchem products, carrageenan has the EU additive E-number E407.
APPLICATION FUNCTION
Chocolate milk: Cocoa suspension and mouth feel.
Ham injection: Improve succulence, yield and slice ability.
Nappage: Provides a transparent flexible glaze that eliminates syneresis.
Hot fill Dairy dessert:  Gelling agent and syneresis control. Provides body and creaminess.
Instant mousse: Viscosity control, improves foam structure and body.
Thickened milk drinks: Suspends insoluble materials, improves mouthfeel and helps stabilise emulsions. food thickeners.
Oil free dressings: Suspends particulates, improves texture and mouth feel.
Ice Cream & Sorbet: Whey off protection. Texture modification.
Flans: Gelling agent and syneresis control.
Processed cheese: Gelling agent. Allows reduction in dairy protein levels. Cost reduction.
Ground meat emulsions: Improves succulence and yield. Prevents shrinkage upon cooking.

Carrageenans (E407)

Application
Carrageenans (E407) are widely used as gelling agents, thickeners and stabilisers.  The addition of various ions or Locust Bean Gum can be used to modify the texture. They can be found in dairy products, beverages, meat products, water gels and powdered desserts. When used as gelling agents in water, they give a wide variety of textures from firm to weak and from elastic to brittle.
Carrageenans are used as stabilisers for foams, ice cream, condensed milk, cream and salad dressings.Due to their protein reactivity, carrageenans produce very economical milk gels. Weak, semi-gelled systems can be used to stabilise chocolate milk, giving mouth feel and cocoa suspension. Cold water-soluble types of carrageenan can be used in instant chocolate milk powders to provide similar properties.
Properties
Carrageenans are large, highly flexible molecules which curl forming helical structures. This gives them the ability to form a variety of different gels at room temperature. They are widely used in the food industry as thickening and stabilising agents. A particular advantage is that they are thixotropic-they thin under shear stress and recover their viscosity once the stress is removed. This means that they are easy to pump but stiffen again afterwards.
Kappa carrageenan is potassium-sensitive and will form strong brittle, thermo-reversible gels in the presence of potassium ions. Calcium and most polyvalent ions will induce gelation to a lesser extent, while the sodium salt is non-gelling and cold water-soluble. All other salts of Kappa carrageenan need to be heated above 50°C, generally to 80°C, to ensure complete dissolution. The gels are generally clear but calcium ions product slight cloudiness. Kappa carrageenan gels do exhibit some syneresis, and are not freeze/thaw stable. Kappa carrageenan will produce strong milk gels at very low levels.
Iota carrageenan forms transparent elastic thermo-reversible gels in the presence of calcium ions. Without the ions, considerable thickening occurs. All salts of iota carrageenan are soluble in cold water and milk and are freeze/thaw stable. The gels do not exhibit syneresis.
Lambda carrageenan does not gel in water or milk but it produces considerable thickening in milk and will stabilise both water and milk systems. It is cold water-soluble, thickening immediately to give a clear viscous solution.
The above three types of carageenan are usually blended and many of the available grades contain various food additives to alter the physical properties for specific uses. In particular, locust bean gum is used to modify Kappa carrageenan, increasing the elasticity, cohesion and breaking strength of the gel.

4 kinds of thickeners

Agar agar is the "vegetarian gelatine". It is sometimes also referred to as "kanten" (the Japanese term). It is derived from a South East Asian seaweed. This article sets out how to use agar agar.Agar agar is used throughout the world to provide a solid surface containing medium for the growth of bacteria and fungi. Microbial growth does not destroy the gel structure because most microorganisms are unable to digest agar. Agar is typically sold commercially as a powder that can be mixed with water and prepared similarly to gelatin before use as a growth medium.
Guar gum is a polysaccharide, a long chain made of sugars galactose and mannose. Some other familiar polysacharides are starch and cellulose, which are made of long chains of the sugar glucose. Guar Gum is normally undertaken by using process of roasting, differential attrition, sieving & polishing in the commercial production. The main properties of Guar Gum are as follows. Due to its various properties day by day new industrial application of Guar gum increases for commercial uses.
Pectin is a natural part of human diet, but does not contribute significantly to nutrition. The daily intake of pectin from fruits and vegetables can be estimated to be around 5 g. Amidated pectin is a modified form of pectin. Here, some of the galacturonic acid is converted with ammonia to carboxylic acid amide. These pectins are more tolerant of varying calcium concentrations that occur in use.Pectin is a complex carbohydrate, which is found both in the cell walls of plants, and between the cell walls, helping to regulate the flow of water in between cells and keeping them rigid. You’ll note some plants begin to lose part of this complex carbohydrate as they age.
Alginates are extracted from brown seaweed and are available in sodium, ammonium and potassium derivatives. They are soluble in both hot and cold water, and can thicken and bind. Sodium Alginate works as a cold gelling agent that needs no heat to gel. It gels in the presence of calcium compounds. Most commonly used with calcium chloride to make caviar and spheres. It is also used in indigestion tablets. Sodium alginate has no discernable flavor.

Some thickeners food additives

Agar agar is extracted from marine red algae that are 100% natural. These chemical properties allow it to swell on contact with water. Thanks to this, you'll be able to concoct taste light and satiating dishes. You'll find the Agar agar most often in the form of white powder. You can then incorporate it into all sorts of dishes, and it gels below 40°. It is an ingredient completely odorless and tasteless, which has only 3 calories per gram.
Guar gum can best be described as a natural food thickener, similar to locust bean gum, cornstarch or tapioca flour. Guar gum is said to have significantly more thickening ability than cornstarch, at a fraction of the cost. Guar gum is not just a thickening agent, but a binder and plasticizer as well. When untreated ice cream melts and refreezes, grainy ice crystals often form. Guar Gum has the natural ability to bind with water molecules, preventing them from forming the unwanted crystals. Processed foods with creamy textures are primarily held together with binders such as guar gum. Without a binder, the individual ingredients might separate into a watery mess.
Pectin in the plant starting material is part of a very complex structure, which gives shape to the soft non-woody parts of the plant. When Pectin is extracted, much of the hairy regions are destroyed, leaving mainly the smooth galacturonic acid regions, with a few neutral sugar units attached or in the main linear chain.
Sodium Alginate are extracted from brown seaweed and are available in sodium, North and South America, New Zealand, Australia, and South Africa) is used by the food industry to increase viscosity and as an emulsifier. It is also used in indigestion tablets. Sodium alginate has no discernable flavor.
Xanthan gum is considered a polysaccharide in scientific circles, because it is a long chain of three different forms of sugar. Xanthan Gum is used in dairy products and salad dressings as a thickening agent and stabilizer; It is used as a substitute for wheat gluten in gluten-free breads, pastas and other flour-based food products. One lesser-known use of xanthan gum is in the oil industry. As a natural thickener, it can be added to drilling fluid or drilling mud to improve its function.

Food thickeners are used in cooking

When using flour as thickener in cooking, you must take care to prevent lumping. Stir the flour and sugar together before adding them to liquid. Flour-thickened sauces are also sometimes additionally thickened and enriched with eggs.Before using gelatin, soften it in a cool liquid. Once the gelatin has absorbed the liquid, gently heat to melt the crystals.
This will naturally thicken any soup or stew. You can also use a roux of butter and flour as thickeners. Alternatively, cream can also be used to thicken soup. In fact, it also adds a luxurious richness to your soup.It is commonly found in ice creams, juice drinks, jams, jellies and other canned foods. Red dye is also a harmful food additive among the harmful synthetic food colors category.
Not just FD&C blue 1, but the whole class of FD&C blue has some minor and major allergy intolerances and health hazards related to them, directly or indirectly. BHA is an infamous food additive, known for causing cancer and other health risks, But despite the dangers associated with the food additives, it is still among the commonly used packaged food preservatives.
But it is often due to lack of awareness and knowledge about these harm food ingredients and harmful additives, that majority of the population ends up having them. The list of food additives to avoid helps in understanding what are the most harmful of these additives lot and are capable of causing, food allergies and intolerances.Food additives, both natural and chemical food additives are found in almost all the packaged food available in the market.

Other thickeners: Carboxy Methyl Cellulose            Guar Gum                Konjac Gum

How to use thickeners in cooking

Food thickeners are used to have more thickness or consistency in liquid food.Many types of thickeners are used in prepared food or the processed food we buy but did you know that we use so many food thickeners in cooking everyday right at our homes too.
Thickeners are added to food to increase its viscosity liquids and are composed of carbohydrates.This process makes the starch granule trap water molecules, thickening the food. Thickeners are added to a wide variety of products including sauces and gravies.But not all of them are safe.Harmful ingredients are usually chemical food additives that should be avoided. But it is often due to lack of awareness and knowledge about these harm food ingredients and harmful additives, that majority of the population ends up having them.
Harmful ingredients are usually chemical food additives that should be avoided. But it is often due to lack of awareness and knowledge about these harm food ingredients and harmful additives, that majority of the population ends up having them. Let's have a look at a few of the most harmful of these dangerous food additives and what can be the probable food allergy intolerances associated with them.
Here are some common thickeners that are used for preparing foods like soup, stew, pudding and many other homemade food. Food thickeners used in cooking have to be in right quantity and right manner to get the required consistency in food. For instance, if a custard is cooked over direct heat and stirred constantly, you'll get a sauce that pours easily. When you want these thickeners to be diluted before adding them to other ingredients, mix them with a small amount of cool liquid.
