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.

Medical Reference Vitamin C (Ascorbic acid)
Vitamin C is a water-soluble vitamin, meaning that your body doesn’t store it.
We have to get what we need from food, including citrus fruits, broccoli, and
tomatoes.
You need vitamin C for the growth and repair of tissues in all parts of your body. It helps the body make collagen, an important protein used to make skin, cartilage, tendons, ligaments, and blood vessels. Ascorbic acid powder is needed for healing wounds, and for repairing and maintaining bones and teeth.
Vitamin C is an antioxidant, along with vitamin E, beta-carotene, and many other plant-based nutrients. Antioxidants block some of the damage caused by free radicals, substances that damage DNA. The build-up of free radicals over time may contribute to the aging process and the development of health conditions such as cancer, heart disease, and arthritis.
It’ s rare to be seriously deficient in Ascorbic acid, although evidence suggests that many people may have low levels of Ascorbic acid. Smoking cigarettes lowers the amount of Ascorbic acid in the body, so smokers are at a higher risk of deficiency.
Signs of vitamin deficiency include dry and splitting hair; gingivitis (inflammation of the gums) and bleeding gums; rough, dry, scaly skin; decreased wound-healing rate, easy bruising; nosebleeds; and a decreased ability to ward off infection. A severe form of Ascorbic acid deficiency is known as scurvy.
Low levels of Ascorbic acid have been associated with a number of conditions, including high blood pressure, gallbladder disease, stroke, some cancers, and atherosclerosis, the build-up plaque in blood vessels that can lead to heart attack and stroke. Getting enough vitamin C from your diet — by eating lots of
fruit and vegetables — may help reduce the risk of developing some of these conditions. There is no conclusive evidence that taking vitamin C supplements will help or prevent any of these conditions.
Ascorbic acid plays a role in protecting against the following:
Common Cold
Despite the popular belief that Ascorbic acid can cure the common cold, the scientific evidence doesn’t support the notion. Taking vitamin C supplements regularly (not just at the beginning of a cold) produces only a small reduction in the duration of a cold (about 1 day). The only other piece of evidence supporting Ascorbic acid for preventing colds comes from studies examining people exercising in extreme environments (athletes such as skiers and marathon runners, and soldiers in the Arctic). In these studies, foodchem Ascorbic acid did seem to reduce the risk of getting a cold.
Heart Disease
Some studies — though not all — suggest that Ascorbic acid, acting as an antioxidant, can slow down the progression of atherosclerosis (hardening of the arteries). It helps prevent damage to LDL (“bad”) cholesterol, which then builds up as plaque in the arteries and can cause heart attack or stroke. Other studies suggest that Ascorbic acid may help keep arteries flexible.
Results of scientific studies on whether Ascorbic acid is helpful for preventing heart attack or stroke are mixed. Ascorbic acid doesn’t lower cholesterol levels or reduce the overall risk of heart attack, but evidence suggests that it may help protect arteries against damage.
In addition, people who have low levels of Ascorbic acid may be more likely to have a heart attack, stroke, or peripheral artery disease, all potential results of having atherosclerosis. Peripheral artery disease is the term used to describe atherosclerosis of the blood vessels to the legs. This can lead to pain when walking, known as intermittent claudication. But there is no evidence that taking Ascorbic acid supplements will help.
The best thing to do is get enough Ascorbic acid through your diet. That way, you also get the benefit of other antioxidants and nutrients contained in food. If you have low levels of Ascorbic acid and have trouble getting enough through the foods you eat, ask your doctor about taking a supplement.
High Blood Pressure
Population based studies (which involve observing large groups of people over time) suggest that people who eat foods rich in antioxidants, including vitamin C, have a lower risk of high blood pressure than people who have poorer diets. Eating foods rich in Ascorbic acid is important for your overall health, especially if you are at risk for high blood pressure. The diet physicians most frequently recommend for treatment and prevention of high blood pressure, known as the DASH (Dietary Approaches to Stop Hypertension) diet, includes lots of fruits and vegetables, which are loaded with antioxidants.

Carboxy Methyl Cellulose-CMC(E466)
Application
Carboxy Methyl Cellulose-CMC(E466) is used as a stabiliser, thickener, film former, suspending agent and extender. Applications include ice cream, dressings, pies, sauces, and puddings. It is available in various viscosities depending on the function it is to serve.
CMC is used to thicken dry mix beverage, syrups, ripples and ice cream, and also to stabilise ice cream, batters and sour milk. It gives moisture retention to cake mixes and water binding and thickening to icings. Food additives CMC tends to give clear, slightly gummy, solutions. It is generally soluble in cold water but difficult to disperse in hot.
Chemistry
Carboxy Methyl Cellulose-CMC(E466) is extracted from plant tissue, mainly wood pulp and cotton, but because it is chemically modified it cannot be classified as a natural food ingredient. Native cellulose is inert and insoluble, but modification makes it soluble.
Properties
CMC is soluble in cold water to give clear and colourless solutions with neutral flavour.
Viscosity production is the primary property of CMC.
With instant products, CMC is used to provide the required rapid build-up of viscosity, for example in powdered beverages.
The viscosity produced by CMC contributes to the stabilisation of frozen products such as ice cream, water ices and ripples. Benefits include the conservation of texture and inhibition of ice crystal formation, a slow meltdown and an improved resistance to dripping and better heat shock resistance.
The thickening effects of CMC can be used in products such as salad dressings and tomato sauces. Food thickeners CMC properties that make it suitable for these applications include its rapid solubility in both hot and cold water, its good water binding and good tolerance to low pH levels.
For soft drinks CMC provides body or mouth feel to low calorie drinks sweetened with intense sweeteners, to more closely match the mouth feel obtained with sucrose or glucose syrup, and to inhibit ‘neck ringing’ by flavour oils in beverages.
Bakery products also benefit from incorporation of CMC. In cake mixes and batter mixes, CMC can improve the volume yield as a result of its viscosity drop during baking and improve the suspension and distribution of ingredients such as fruit. CMC can also provide improved yields and improved moistness after storage, and be used to increase yield or retard staling and hence prolong shelf life.
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.

The Pros and Cons of natural Vegetables
The phrase natural when utilized to describe fruits and veggies connote one thing that is not altered from its natural connect by pesticides and preservatives. while it may possibly be complicated to distinguish natural veggies from conventional ones, there are food additives rigid federal government rules arranged over the US division of Agriculture. Fruits and veggies can only be labeled natural if they met these standards. receiving a thorough knowing from the benefits and drawbacks of natural veggies will totally support you choose which one to buy.
This shows that there are no artificial or commercial pesticides, herbicides, fungicides or fertilizers which could be utilized in the direction of veggies through the time they are planted up in the direction of your time which they are harvested. In natural farming every one of the farming resources utilized are natural. For example, the fertilizers that make the soil fertile come about from animal manure and compost as well as the food sweeteners pesticides which could be utilized to repel pests are also other naturally-sourced materials. This assures that natural veggies develop and therefore are harvested within their purest form. this could make natural veggies taste an ideal offer better than conventionally grown ones.
The accumulation of pesticide residues within our bodies carries with it the opportunity of many important illnesses like cancer, tumors and allergies, among others. These pesticides could possibly be passed on through the mom to child through being pregnant and through boobs milk. Moreover, research projects show significant proof that back links pesticide protection to fetal abnormalities, reduced delivery weight, behavioral matters and impaired engine skills. youthful children who are subjected to pesticides in the earlier phase existence are prone to many progress and developmental retardation.
This distinction could possibly be attributed in the direction of high priced farming methods of natural veggies as well as the simple fact that really amount of farmers go organic. There is a whole great offer more handbook hold out required in natural farming because they do not use Aspartame informations and News substance compounds in enhancing their crops. and also this adds up in the direction of cost. For example, instead of spraying the veggies with herbicides they generally resort to handbook weeding and crop rotation that is doubly expensive. Also, achieving natural official certifications through the federal government entails additional expense.
This is because natural veggies do not get artificial waxes or preservatives to stay fresh. over the time they accomplish the purchaser they are generally fresh. However, because they do not get sprayed with preservatives on top of that to other artificial substance compounds additionally they have shorter shelf lives.
