Escopo e aplicabilidade

This standard applies to feed additive betaine products, specifically encompassing both natural betaine (separated and processed from sugar beet molasses) and synthetic betaine (chemically synthesized from sodium chloroacetate and trimethylamine). It is essential for manufacturers and importers of animal feed additives containing betaine. The standard does not apply to other types of vitamins or feed additives not explicitly covered in this specific part.

Requisitos técnicos

GB 7300.203-2020 establishes mandatory technical specifications for betaine feed additives, categorized into Type I, Type II, and Natural betaine. The core requirements dictate strict limits on the active betaine content (calculated on a dry basis) to ensure product efficacy. Additionally, the standard sets maximum thresholds for critical quality and safety parameters, including loss on drying, ignition residue, and heavy metal contamination (such as Lead and Total Arsenic). Manufacturers must strictly control these chemical and physical parameters to ensure product safety. Specific impurities are also regulated depending on the betaine type. For instance, limits are established for sodium chloride in synthetic betaine and sulfates in natural betaine. Furthermore, the standard mandates limits for total free amines/ammonia across all product categories to prevent toxicity and ensure formulation stability.

Métodos de ensaio

The standard outlines rigorous analytical procedures to verify compliance. Betaine content is primarily determined using Ion Chromatography (serving as the arbitration method) or alternatively by Perchloric Acid Titration. Safety and purity assessments include measuring Loss on Drying and Ignition Residue via standard gravimetric methods. Heavy metals and total arsenic are evaluated following the protocols outlined in GB/T 13079-2006 and visual colorimetric methods. Specific impurity tests, such as the Volhard titration for sodium chloride and turbidity comparison for sulfates, are also detailed.

Perguntas frequentes

What products are regulated under GB 7300.203-2020?

GB 7300.203-2020 regulates feed additive betaine, covering both natural betaine (derived from sugar beet molasses) and synthetic betaine (produced via chemical synthesis). It sets mandatory requirements for their technical specifications and testing methods.

Are there any updates from the previous version of this standard?

The standard replaced GB/T 21515-2008. Key updates include expanding the scope to cover synthetic betaine, adding technical indicators for free amines and sodium chloride, and updating the determination of betaine content to use ion chromatography as the arbitration method.

Is compliance with GB 7300.203-2020 mandatory?

Chapters 1, 4, and 6 of this standard are mandatory, while the remaining chapters are recommended. This means the scope, technical requirements, and inspection rules must be strictly followed for compliance.
