GB 22489-2017 (English Version) PDF

Scope: This standard specifies the requirements, test methods, inspection rules and labels, packaging, transportation, storage and shelf life of feed additive manganese methionine complex (chelate). This standard is applicable to the feed additive manganese methionine synthesized from human manganese salt and methionine (2-nitro-4-methylthio-butyric acid) with a molar ratio of 2:———1 or 1:1 Complex (five) compound. Manganese methionine complex (penta) with a methionine-manganese molar ratio of 2:1: the molecular formula is Co Hz Ns*OiSs*Mn; relative molecular mass: 351.4 (according to the international relative atomic mass in 2007). Methionine manganese complex (penta) compound with methionine-manganese molar ratio of 1:1; molecular formula is C:HuNOsSs Mn; relative molecular mass: 300.2 (according to the international relative atomic mass in 2007).
