Application areas:

Amino acid zinc has good stability in the premix, and its damage to vitamin E and vitamin C is significantly less than that of inorganic salts. Add Zn-Met or ZnSO4 to the refined feed based on egg white or soybeans, and feed the 1-year-old channel catfish for 10 weeks. The results showed that in the egg white diet group, the addition amounts of Zn-Met and ZnSO4 were 5.58 mg/kg and 18.94, respectively. At mg/kg, the fish body can obtain the maximum body weight. When the addition amount of Zn-Met and ZnSO4 are 6.58mg/kg and 19.91mg/kg, respectively, the zinc content in the bone reaches the maximum deposition; while in soybean-based In the bait group, when the supplements of Zn-Met and ZnSO4 were 5.91mg/kg and 30.19mg/kg, the fish body could gain the maximum body weight. The supplements of Zn-Met and ZnSO4 were 12.82mg/kg and ≥80mg/kg, respectively. The zinc content in the bone reaches the maximum deposition amount at kg. Added 1.5% phytic acid and 4% calcium phosphate to a semi-refined feed with a zinc content of 30 mg/kg, and added amino acid chelated zinc or zinc sulfate. It was found that the weight gain of rainbow trout in the amino acid zinc group was significantly higher than that of the same dose. In the sulfuric acid group, the results show that the amino acid zinc still has a higher biological advantage in the presence of phytic acid or calcium phosphate.

Zinc glycinate is a good food zinc fortifier, which plays an important role in the intellectual and physical development of infants and adolescents, and has a better absorption effect than inorganic zinc. my country stipulates that it can be used in foods for infants and young children, and the usage amount is 25~70mg/kg (in terms of zinc, the same below); in dairy products, it is 30~60mg/kg; in fortified zinc beverages, cereals and their products, it is 10~20mg /kg. Production method Under alkaline conditions, glycine reacts with zinc oxide, purified and refined to obtain finished products.

The bioavailability of amino acid zinc is high. The reason may be that after the metal element zinc forms a chelate with amino acid, the intramolecular charge tends to be neutral, which can maintain good stability in the digestive tract, and is affected by other inorganic ions or antagonists. Small, it is not easy to combine with other substances to form insoluble compounds or be adsorbed on insoluble colloids.
