Foreword

Chapters 1, 4 and 6 of this standard are mandatory and the rest are recommended. This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 7296-2008 "feed additive vitamin B1 (thiamine nitrate)", compared with GB/T 7296-2008 The main technical changes are as follows. ---Technical index "lead" was changed to "heavy metal (in Pb), ≤10.0mg/kg" (see 4.2, 3.2 of.2008 edition); --- Increase the technical indicator "total arsenic, ≤2.0mg/kg" (see 4.2); --- Technical indicators changed from "residue residue, ≤0.2%" to "residue residue, ≤0.1%" (see 4.2, 3.2 of.2008 edition); --- Determination of thiamine nitrate content The silicotungstic acid precipitation method is an arbitration method, and the potentiometric titration method is added (see 5.3). This standard is proposed and managed by the Ministry of Agriculture and Rural Affairs of the People's Republic of China. This standard is mainly drafted by. National Feed Quality Supervision and Inspection Center (Wuhan), China Feed Industry Association. The main drafters of this standard.
