introduction
Feed additives refer to small or trace substances added during feed processing, production, and use, including nutritional feed additives.
And general feed additives. For ease of use, GB 7300 "Feed Additives" is divided into the following 13 categories according to product categories.
---Amino acids, amino acid salts and their analogues;
---Vitamins and vitamin-like substances;
---Mineral elements and their complexes (chelates);
---Enzyme preparations;
---microorganism;
---Non-protein nitrogen;
---Antioxidants;
---Preservatives, mildew inhibitors and acidity regulators;
---Colorants;
---Seasoning and attractant substances;
---Binders, anti-caking agents, stabilizers and emulsifiers;
---Polysaccharides and oligosaccharides;
---other.
The product α-galactosidase in this document belongs to the fourth category of enzyme preparations, because α-galactosidase is the fifth product standard issued in this category.
Therefore, this document is numbered GB 7300.405 and is part 405 of GB 7300.
