Aperçu de conformité

Cet aperçu n’est actuellement disponible qu’en anglais.

Champ d’application

This standard applies to feed additives containing Bacillus coagulans, specifically those produced using bacterial fermentation, with or without the addition of carriers, followed by a drying process. It is strictly applicable to products entering the Chinese animal feed market. It does not cover other microbial strains or non-microbial feed additive categories.

Exigences techniques

The standard outlines the raw materials and strain requirements, specifying that the strain must be Bacillus coagulans and materials must originate from approved Chinese feed catalogs. It establishes strict sensory requirements, dictating that the product must have uniform color, be free of mold and off-odors, and show no caking. Manufacturers must ensure their product's appearance aligns with these baseline physical parameters. For quality indicators, the standard sets definitive thresholds for viable bacteria count, moisture content, and particle size. Compliance with these quantitative metrics is mandatory for market approval. Additionally, it enforces rigorous hygiene indicators, limiting heavy metals (such as arsenic, lead, mercury, and cadmium), mycotoxins like Aflatoxin B1, and pathogenic microorganisms including Salmonella, which must not be detected in 25g samples. The standard also details packaging, transportation, and storage protocols. Packaging materials must be non-toxic, moisture-proof, and opaque. Products must be stored in ventilated, dry conditions to prevent contamination and degradation.

Méthodes d’essai

The standard mandates specific testing protocols for strain identification and quality assurance. Identification involves morphological observation, physiological and biochemical verification, and molecular biology techniques using 16S rRNA sequencing. Accurate strain identification is critical for regulatory compliance. Viable bacteria counting is performed using specialized plate methods on modified MRS agar. Furthermore, the standard references various GB/T methods for determining moisture, particle size, heavy metals, and microbial contamination limits.

Questions fréquentes

What products are regulated under GB 7300.505-2025?

This standard regulates feed additives containing Bacillus coagulans, which are produced via fermentation, with or without a carrier, and subsequent drying processes.

When does GB 7300.505-2025 become effective, and does it allow a transition period?

It is a newly released standard published on June 30, 2025, and will become mandatory starting July 1, 2026. Products manufactured or imported before this implementation date can be sold until their labeled expiration date.

How does GB 7300.505-2025 differ from international ISO standards?

The standard references Chinese national testing methodologies, such as GB/T 13091 for Salmonella and GB/T 13092 for mold enumeration. Overseas manufacturers must ensure their testing protocols align with these specific GB/T methods or equivalent ISO standards accepted by Chinese regulatory authorities.
