Vitamin C CAS 50-81-7 or L-ascorbic acid, is an essential nutrient for humans 
and
certain other animal species. Ascorbic acid is a naturally ooccurring
organic compound with antioxidant properties. It is a white solid and
dissolves well in water to give mildly acidic solutions. Because it is
derived from glucose, many animals are able to produce it, but humans
require it as part of their nutrition. Other vertebrates which lack the
ability to produce ascorbic acid include other primates, guinea pigs,
teleost fishes, bats, and some birds, all of which require it as a
dietary micronutrient (that is, in vitamin form).
Vitamin C is colorless crystals or a white or almost white, crystalline powder which discolors on exposure to air and moisture; Odorless or almost odorless and tasted sour; Easily soluble in water and a few partial soluble in ethanol; Insoluble in ether and chloroform.

Application
In the pharmaceutical industry, Ascorbic acid can be used mainly to produce various medicines as clinically important material for supplementary cure practice in different sectors. It is also used to treat scurvy and various acute and chronic infections diseases, are applicable to the lack of VC.
In the food industry,it can both use as nutrition-al supplements,supplementary VC in food processing,and also is good Antioxidants in food preservation,widely used in meat products,fermented flour products,beer,tea dtinks,fruit juice,canned fruit,canned meat and so on;
Ascorbic acid is also commonly used in cosmetics, feed additives and other industrial areas.
Benzoic Acid is a colorless crystalline solid and a simple aromatic carboxylic acid.
MSG can enhance the natural flavor of meat, poultry, fish and vegetables, and is a popular flavor.
Citric acid is an important organic acid, also known as citric acid, colorless crystals, often containing a molecule of crystal water, odorless, strong acidity, soluble in water.
Citric acid anydrous CAS 77-92-9 Citric acid monohydrate CAS 5949-29-1 is organic acids in the first big acid, as a result of the performance of physical properties, chemical properties, derivatives, mainly used in food and beverage industry as sour agent, flavouring agent, preservative and antistaling agent.
Calcium Propionate can inhibit growth of some individual molds and bacteria and is widely used in grain products such as bread.
Sodium benzoate can be produced by reacting sodium hydroxide with benzoic acid.Potassium benzoate (E212), the potassium salt of benzoic acid, is a food preservative that inhibits the growth of mold, yeast and some bacteria.
Calcium acetate CAS 62-54-4 is white crystalline particle or crystalline powder, with slightly propionic acid odor.
Sodium saccharin is a white odorless and intensely sweet crystalline powdered food additive. Its sweetness is about 500 times that of sucrose. It is easily soluble in water. The food industry uses sodium saccharin as an additive in various products.Also use in Medcine and electroplating industry.
