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 type.
---Amino acids, amino acid salts and their analogs;
---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 food attractants;
---Binders, anti-caking agents, stabilizers and emulsifiers;
---Polysaccharides and oligosaccharides;
---other.
The product glycine iron complex in this document belongs to the third category of mineral elements and their complexes (chelates).
This is the fourth product standard released in this category, so this document is numbered GB 7300.304 and is part 304 of GB 7300.
