f) The determination methods for the content of canthaxanthin are changed (see 7.3.2; 4.4 of Edition 2003);
g) The requirements for shelf life are added (see 9.5).
Attention is drawn to the possibility that some of the contents of this document may be the subject of patent rights. The issuing body of this document shall not be held responsible for identifying any or all of such patent rights.
This document was proposed by and is under the jurisdiction of Ministry of Agriculture and Rural Affairs of the People's Republic of China.
The previous edition of this document is as follows:
——GB/T 18970-2003.
Introduction
Feed additives refer to a small amount or trace substances added in the process of feed processing, production and use, including nutritional feed additives and general feed additives. For the convenience of application, GB 7300 Feed additives is divided into the following 13 categories:
——Amino acids, their salts and analogues;
——Vitamins, provitamins and chemically well-defined substances having similar effect;
——Minerals and their complexes (or chelates);
——Enzymes;
——Live microorganisms;
——Non-protein nitrogen;
——Antioxidant;
——Preservatives and acidity regulators;
——Coloring agents;
——Flavouring and appetising substances;
——Bonding agent, anti-caking additives, stabilizers, and emulsifiers;
——Polysaccharides and oligosaccharides;
——Others.
The product of this document, beta,beta-carotene-4,4-diketone (canthaxanthin), belongs to Category 9 coloring agents. As beta,beta-carotene-4,4-dione (cantharidine) is the second published product standard in this category, this document is designated GB 7300.902 as Part 902 of GB 7300.
