Escopo e aplicabilidade

This standard applies to feed additive Thiamine hydrochloride (Vitamin B1) produced via chemical synthesis using aminopropionitrile as the raw material. It is mandatory for all manufacturers and suppliers of this specific feed additive in China. It covers the requirements, testing methods, inspection rules, labeling, packaging, transportation, storage, and shelf life. It does not apply to other forms of Vitamin B1 or feed additives produced through different processes.

Requisitos técnicos

The standard specifies the physical and chemical requirements for Thiamine hydrochloride (Vitamin B1). Physically, the product must appear as a white crystalline powder with a slight characteristic odor and a bitter taste. Chemically, the standard sets strict limits on the purity of Thiamine hydrochloride (calculated on a dry basis), as well as limits for loss on drying and ignition residue. It also mandates specific ranges for acidity (pH) and maximum allowable limits for sulfate content, heavy metals (as Pb), and total arsenic (as As). Furthermore, the standard specifies a limit for solution color to ensure product clarity and consistency. Compliance with all these technical indicators is strictly enforced.

Métodos de ensaio

The standard outlines several key testing methods to verify compliance. Identification tests include chemical reactions for fluorescence and chloride presence, alongside an Infrared Spectrophotometry comparison. The primary method for determining Thiamine hydrochloride content is the Silicotungstic Acid Precipitation method (designated as the arbitration method), with an alternative Non-aqueous Titration method using perchloric acid also provided. Additional tests cover solution color comparison, pH measurement, sulfate determination via turbidity comparison, loss on drying, ignition residue, and heavy metals analysis using a visual colorimetric method. Total arsenic is determined according to the referenced standard GB/T 13079.
