The application of chemical raw materials in food industry

We eat different kinds of food everyday, different colors, different tastes, different shapes and even different functions. Then how are these generated? Here are some different examples as following:
1. Caustic soda: accurate to say that we do not add the caustic soda in food, we just use it to in the course of food-related. It is also named Sodium hydroxide, it is a kind of white flake or granular form.

People usually use it in combing out the containers and the work piece process of amylum.
2. Tartaric acid: the chemical formula of the tartaric-acid is C4H6O6.The appearance of tartaric-acid is colorless crystal or white crystalline powder, odorless, and taste sour.

With the new varieties of red beet in our country continue to promote increased acreage, red beet itself is high-volume, low price, for the production of red pigment in beets provide sufficient raw materials, coupled with the extraction conditions are relatively easy to achieve, in our conditional develop beet red pigment production. At the same time as people demand increases, we must attach importance betalain purification process improvements, and to select an ideal vehicle to stabilize the pigment research.
4. Bilberry Extract : it is a kind of brown powder extract products of Rosaceae Rubus Chingii fruits. It contains organic acids, sugars, ellagic acids and sitosterol and so on. Function of kidney and fixing sperm, used for kidney empty enuresis burning on urination and the frequency of impotence premature ejaculation ejaculation of semen leakage.
