この概要は現在英語のみで提供しています。
適用範囲
This standard applies to feed additive β-mannanase products derived from fungal strains listed in the Feed Additive Variety Catalog, processed via fermentation, separation, and carrier addition. It is applicable to both solid and liquid enzyme preparations used in animal feed. It does not apply to other types of enzyme preparations or non-microbial feed additives.
技術要求
The standard specifies comprehensive technical requirements for β-mannanase, categorized into appearance, quality indicators, and hygiene parameters. For appearance, solid forms must be uniform and free-flowing without mold, while liquid forms must be homogeneous with minimal precipitation. Quality indicators mandate minimum enzyme activity levels and specific physical parameters like moisture content and particle size for solid forms, and pH ranges for liquid forms. Hygiene parameters strictly limit heavy metals (such as arsenic, lead, cadmium, and mercury) and microbial contaminants, including Salmonella and E. coli.
試験方法
Testing methods involve visual inspection for appearance and specific analytical procedures for quality and hygiene parameters. Enzyme activity is determined using a spectrophotometric method referenced in GB/T 36861. Heavy metals and mycotoxins are tested using standardized chromatographic and spectroscopic methods to ensure compliance with safety limits. Microbial contaminants are evaluated using established cultural and enumeration techniques.
よくある質問
What products are regulated under GB 7300.404-2025?
This standard applies to feed additive β-mannanase products derived from approved fungal strains, available in both solid and liquid forms. It is mandatory for all manufacturers producing or supplying this specific enzyme to the Chinese market.
Are there any updates from the previous version of GB 7300.404?
As a newly released standard (effective July 1, 2026), it provides updated technical and safety requirements for β-mannanase, aligning with current Chinese feed safety regulations. Manufacturers must transition to these new specifications to maintain market access. It specifically references GB/T 36861 for standardized enzyme activity determination.
How does GB 7300.404-2025 differ from ISO standards?
While the core testing methodologies often align with international practices, this standard incorporates specific Chinese regulatory limits for mycotoxins and heavy metals as defined by the national feed safety framework. Compliance with ISO standards does not automatically guarantee compliance with GB requirements.
The summary above provides a high-level overview of GB 7300.404-2025. To ensure complete compliance for your feed additive products entering the Chinese market, a precise and professional translation of the full technical specifications is essential.
