Compliance overview
Scope and applicability
This standard applies to feed additive betaine hydrochloride synthesized from trimethylamine and chloroacetic acid, sodium carbonate, or sodium hydroxide. It covers the technical requirements, testing methods, and labeling for this specific vitamin/provitamin-like substance used in animal feed. It is not applicable to other forms of betaine or unrelated feed additives. Manufacturers must ensure their production process aligns with the defined synthesis route.
Technical requirements
The standard specifies stringent requirements for betaine hydrochloride used in animal nutrition. Key technical parameters include the minimum content of the active compound, maximum limits for loss on drying and ignition residue, and strict thresholds for heavy metals (Pb) and total arsenic (As). Compliance with these chemical and physical parameters is mandatory for market access. The standard also defines the required appearance as a white, crystalline, and hygroscopic powder, along with specific identification criteria for both the betaine and hydrochloride components. Additionally, it sets limits for free amine/ammonia and specifies an acceptable pH value range.
Testing methods
To verify compliance, the standard outlines several analytical procedures. The primary assay for betaine hydrochloride content utilizes ion chromatography with a cation exchange column and non-suppressed conductivity detection. Other evaluations include visual sensory checks, chemical precipitation for identification, and titration methods for free amine/ammonia. Heavy metals are assessed via visual colorimetry, while total arsenic is determined according to the silver salt method specified in GB/T 13079-2006. Standardized methods from GB/T 6435 and GB/T 6438 are referenced for moisture and ash determination.
