Food additives Gellan Gum

Gellan Gum is the Kelco company in the 1980 s the development of a microbial edible glue. Following the xanthan gum kelco company after the development of a new type and microbe exocellular polysaccharide, its gel xanthan gum is more superior than performance. It is by the false form brain coli Iraq algae (Pseudomonaseloden) of music in neutral condition, with glucose for carbon sources, ammonium nitrate as nitrogen source and some inorganic salt made out of the medium, the aerobic fermentation and produce extracellular polysaccharide colloid, is a new type of completely transparent gel agent. Gellan gum is made up of four sugar molecules in order as D-glucose, D-glucose hyaluronic acid, D-glucose, L-rat lee sugar through the glycosidic bond of polymer connected to the saccharide compounds, one of the first glucose molecules is beta 1, 4 glycosidic bond connection.
Gellan gum powder is rice, no special taste and smell, at about the 150 ℃ without melting and decomposition. Heat resistant, acid performance is good, the stability carrageenan powder e number of enzyme is also high. Insoluble in the polar organic solvent, also not soluble in cold water, but a little mixing is scattered in the water, heating that dissolve into transparent solution, cooling, form transparent and solid gel. Soluble in hot deionized water or integration of existing low ionic strength agent solution, shows neutral aqueous solution.
Although gellan gum production obtained many achievements, but there still exist some problems, such as low production; Used for ventilation of high energy mix; Purification of organic solvent consumption with big; Organic solvent recycle more difficult, etc. So if can use genetic engineering means will produce plastic gene transfer to don’t think gas microorganisms normal expression, food additives and in the absence of oxygen, or the oxygen conditions production is reduced costs. In summary, the genetic engineering means screening high quality polysaccharide produce bacteria, and use of modern biological technology building has a variety of excellent performances gene engineering bacterium and cell engineering bacterium to improve gellan gum yield and quality, will be the future gellan gum production and research development direction.

Eat can become beautiful

As the saying goes: “eat in the face”. This sentence explain adequately “eat” is beauty to raise colour process cannot be ignored in important aspect. So, the skin maintenance to comply with the following principles:
1. Less meat eating foods and animal fats. Under certain conditions, meat and animal fat in the body in the process of decomposition can produce many acidity material, to skin and internal all have strong excitant, affect the normal metabolism of skin. The skin coarse, often is food additives the blood muscle acid caused by increased.
2. Eat more plant food. Plant foods rich in prevent skin coarse, tryptophan levels. Can delay the skin aging, change the skin coarse phenomenon. This kind of food mainly has: black sesame seed, small wheat gluten, oil, beans and its products, gluten, laver, watermelon seeds, sunflower, pumpkin seeds and peanut.
3. Note the protein intake equilibrium. Protein is essential to the human nutrition material, once long-term lack of protein, the skin will lose flexibility, rough, dry face is old. But meat and fish, prawns, crabs and other protein food over food, can cause allergies.
4. Eat fresh vegetables and fruit. The skin is darker, appropriate often absorb turnip, Chinese cabbage, bamboo shoots, wax gourd soy products and rich in plant protein, folic acid and vitamin C food; The skin coarse, should be more rich in vitamin A and D intake of fruits and carrageenan powder e number vegetables. Such as carrots, lotus root, spinach, yellow bean sprouts, yellow, green vegetables, eggs, milk, animal liver. Also absorb enough vitamin and enough plant fiber, to prevent constipation and brings for skin and visceral lesions.
5. Drink less alcohol. Long-term excessive drinking alcohol, can make the skin is dry, rough, aging. A few drinking alcoholic beverages, can promote blood circulation, promote the metabolism of skin, make skin produce elastic and more moist.
6. Appropriate drinking water. The normal adult should be drinking water daily 2000 ml. Plenty of water supply, can delay the ageing of the skin.

Celery leaves nutrition many times higher than celery stems

Celery nutrition is very rich, with protein, fat, carbohydrates, crude fiber, calcium, phosphorus, iron, and other nutritional substances. Among them, the protein content than the general melon and fruit vegetables high 1 times, iron content of tomato is 20 times or so, also contains abundant carotene and many kinds of vitamins.
Celery sex is cool, taste Kennedy and non-toxic, have heat dissipation, wet wind, lack of the blood, clear bowel and then, cough runfei, lower blood pressure, the healthy food additives brain calm function, to high blood pressure, vascular sclerosis, neurasthenia, etc have auxiliary therapy effect. Celery contains a volatile balmy oil, can promote appetite. Eat more celery can also increase the body’s resistance. Due to the rich in water and fiber celery, and contain a can make fat accelerating decomposition, disappear, chemical materials, so is the best food reducing weight.
Nutritionists had to celery stalk and blade had 13 particular nutrients test, celery leaves nutrient found in more than 10 indicators stem. Among them, celery leaves of carotene content is 88 times of the stem, vitamin C content is the stem 13 times, carrageenan powder e number content is 17 times stem, the content of protein of the stem is 11 times, the content of calcium is more than twice the stem. Celery leaves on cancer still has certain inhibition and inhibition rate to 73%. The juice is made it after drink, have very good stimulant.
