National Standard of the P.R.C., Feed additive—Part13: Others—Bile acids; (14 page(s), in Chinese)

This document specifies the chemical name, molecular formula, relative molecular weight and chemical structure of bile acids, specifies the technical requirements, sampling, inspection rules, labeling, packaging, transportation, storage and shelf life of bile acids as a feed additive, and describes the test methods. This document applies to the feed additive bile acids produced by saponification, decolorization, acidification, purification, drying and other processing of technologies from pig bile paste after extraction of bilirubin. It mainly consists of hyocholic acid, hyodeoxycholic acid and chenodeoxycholic acid.
