コンプライアンス概要
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 solid feed additive products utilizing Lactobacillus delbrueckii subsp. lactis as the primary microbial strain. It covers products manufactured through processes such as liquid fermentation, separation, and drying, with or without the addition of carriers. This standard is mandatory for manufacturers producing or exporting this specific microbial feed additive to the Chinese market.
技術要求
The standard outlines the physical, chemical, and biological parameters for the product. It specifies that the appearance must be a uniform powder or granule without off-odors or mold. A critical requirement is the strain identification, which must be verified through morphological, physiological, biochemical, and molecular biology methods. The standard sets strict quality indicators, including minimum viable cell counts and maximum moisture limits. Furthermore, it establishes rigorous hygiene limits for contaminants such as heavy metals (e.g., lead, arsenic, mercury, cadmium) and mycotoxins. Compliance with these microbiological and contaminant limits is essential for product approval.
試験方法
Testing involves several standardized procedures to ensure product integrity. Strain identification is conducted using morphological observation and PCR-based molecular biology techniques, including 16S rRNA sequencing. Viable cell counting is performed using specific plate methods on MRS agar under anaerobic conditions. Additionally, the standard references various national methods for determining moisture, particle size, heavy metals, mycotoxins, and pathogenic microorganisms like Salmonella.
よくある質問
What products are regulated under GB 7300.506-2025?
This standard applies to solid feed additive products containing Lactobacillus delbrueckii subsp. lactis as the active strain, produced via liquid fermentation, separation, and drying processes. It is mandatory for manufacturers exporting microbial feed additives to China.
Are there any specific updates in GB 7300.506-2025 compared to previous versions?
This standard is part of the broader GB 7300 series for feed additives. It specifically focuses on the Lactobacillus delbrueckii subsp. lactis strain, detailing its unique identification methods, specific quality indicators, and corresponding hygiene limits.
How does GB 7300.506-2025 differ from ISO standards for microbial feed additives?
The standard incorporates internationally recognized testing principles, such as 16S rRNA sequencing for molecular identification, but it establishes specific domestic limits for heavy metals and mycotoxins. Manufacturers must ensure their products meet these Chinese national limits rather than just ISO parameters.
The summary above provides a high-level overview of GB 7300.506-2025. 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.
