Scope

This standard specifies the requirements, test methods, inspection rules, and labeling, packaging, transportation, storage, and shelf life for zinc methionine chelate, a feed additive. This standard applies to zinc methionine chelate products synthesized from zinc sulfate and methionine (2 amino 4 methylthio butyric acid) with a molar ratio of 2:1 or 1:1. The molecular formula of the zinc methionine chelate with a molar ratio of 2:1 is C10H20N2O4S2Zn, with a relative molecular mass of 361.80. The molecular formula of the zinc methionine chelate with a molar ratio of 1:1 is (C5H10NO2SZn)HSO4, with a relative molecular mass of 310.65 (based on the 2007 International Atomic Mass Table).
