Food Additive

Sodium dehydroacetate is an antibacterial agent with high safety, wide antibacterial range and strong antibacterial ability. It is less affected by the pH in food, and can maintain high antibacterial efficacy under acidic or slightly alkaline conditions. Its antibacterial ability is better than sodium benzoate, potassium sorbate and calcium propionate. It is an ideal food preservative.

It is used to produce the sedative hypnotic bromoisoamyl urea. But it is more used in the production of spices (80% of the total amount of de boiling in Japan). The main isovalerate used as perfume are hexyl isovalerate, propyl isovalerate, isoamyl isovalerate, geranyl isovalerate, benzyl isovalerate and cinnamyl isovalerate. The lower isovalerates are used as food flavors, and the higher isovalerates are used in cosmetics. Isovaleric acid exists naturally in valerian oil, vanilla oil, hops oil, laurel leaf oil, spearmint oil and so on. It is a kind of edible flavor permitted by GB2760-86. It is mainly used to make cheese and cream flavors, and also to be used in fruit flavor. It is used to make medicine, spice, condiment, etc.

L-hydroxyproline is a common non-standard protein amino acid, as the main raw material of antiviral drug azanavir, it has high application value. L-hydroxyproline is also used as a food additive (used as a sweetener, the dosage is relatively small), and it is used as an intermediate of Peinan side chain in medicine, the dosage is relatively large.

Allicin is an antibacterial substance, which can inhibit the growth and reproduction of dysentery bacilli, typhoid bacilli and Vibrio cholerae. It has obvious inhibition and killing effect on Staphylococcus, Streptococcus and pneumococcus, so it can reduce the incidence rate of chicken and fish. Adding a small amount of allicin to the feed of chickens, ducklings and layers can improve the survival rate of livestock chickens and ducklings and the laying rate of layers. Adding allicin to broilers and ducks can improve the feed utilization rate by 6% - 16%, improve the feed palatability, stimulate oral taste buds and increase animal feed intake. Allicin can improve the flavor of chicken and duck. For fish, allicin is mainly used for disease prevention, treatment and good food attractant. At the same time, it can also combine the added vitamin B1 with garlic thiamine to prevent the decomposition of vitamin B1 by vitamin B2 decomposition enzyme in live bait (FISH). Garlic thiamine has the same effect as vitamin B1, but its absorption is better than vitamin B1 and its physiological effect is better. Therefore, allicin can also prevent fish vitamin B1 deficiency, reduce feed coefficient and promote fish growth.

Calcium ascorbate is mainly used as antioxidant, nutritional supplement and color protection agent. It can be used in soup, soup food and meat products. Added to food does not change the taste of the original food.
