Food(Feed) Additives

Diethyl (2S,3S)-2,3-dihydroxybutanedioate is mainly used in the synthesis of chiral drugs, chiral intermediates and asymmetric catalysis. It is also used in food and animal feed.

It is a kind of non nutritive synthetic sweetener. Its sweetness is 30 times as much as sucrose, but its price is only 3 times as much as sucrose. Besides, it does not have bitter taste as saccharin. As an international food additive, it can be used in cool drinks, fruit juice, ice cream, pastry food and preserves.

Tylosin is a kind of veterinary macrolide antibiotics commonly used in China, also known as tyronon and tylosin. It can be obtained by fermentation of actinomycetes Streptomyces Freund. There are three forms of tylosin alkali, phosphate and tartrate. The antibacterial spectrum is similar to erythromycin. It has inhibitory effects on Gram-positive bacteria and some Gram-negative bacteria, mycoplasma, Vibrio, coccidia and spirochetes. It is particularly effective on mycoplasma, but its effect on Gram-positive bacteria is not as good as erythromycin. This product is characterized by its strong effect on mycoplasma. It is one of the drugs with the strongest anti Mycoplasma effect among macrolides. As a feed additive, it is widely used in the feed of chickens, pigs, cattle, sheep, fish, shrimp and other animals, which can promote the growth of livestock and poultry and improve the feed utilization rate. It is mainly used to control Mycoplasma disease in chickens, turkeys and other animals; Vibrio dysentery and infectious pleuropneumonia in pigs are also used for enteritis, pneumonia, mastitis and endometritis caused by sensitive bacteria. The effect of subcutaneous injection is better than that of oral administration in the treatment of chicken chronic respiratory diseases. The tissue drug concentration after subcutaneous injection is 2 ~ 3 times higher than that of oral administration, and the maintenance time of effective blood drug concentration is also longer. In addition, tylosin phosphate is also used as a growth promoting drug feed additive for cattle, pigs and chickens. There is cross resistance between this product and erythromycin.
