Feed additives—Part 1：Amino acids,their salts and analogues—Taurine
1 Scope
This document gives the chemical name, molecular formula, relative molecular mass and structural formula of taurine, and specifies the technical specifications of taurine as a feed additive.
The standard describes the technical requirements, sampling, inspection rules, labeling, packaging, transportation, storage and shelf life, and describes the test methods.
This document is applicable to the production of products with ethylene oxide or 2-aminoethanol as the main raw materials, after chemical synthesis, with a small amount or no anti-caking agent added.
The feed additive taurine is obtained.
