Definition of amino acids chelated minerals
According to definition of the Association of American Feed Control Officials (AAFCO), chelates are formed from the reaction of a metal ion from a soluble metal salt with amino acids having a mole ratio of 1 mole of metal to 1-3 mole (preferably 2 mole) of amino acid to form coordinate – covalent bonds. The average molecular weight of the amino acids is about 150D and the molecular weight of the chelates preferably does not exceed 800D.
The Official Journal of the European Union (OJEC) (1998) pointed out that the amino acid chelates have a molecular formula expressed as M(x)1-3·nH2O, where the x is the amino acid or peptide, the molecular weight of which was no more than 1500D.
Trend of application
A. limiting the amount of added in feed, more stringent safety requirements.
B. nutrient requirement of minerals is increasing with the improvement of animal breeding.
C. customers require products that are more stable in chemical properties. Do not or less harmful to vitamins and fat in the feed.
D. enhance the immune function of animals; improve anti-stress ability; reduce the use of antibiotics; improve the quality and flavor of animal products (meat, egg and milk, etc.).
E. environmental protection requires manufacturers to improve resource utilization and reduce environmental pollution.
