饲料添加剂 第2部分： 维生素及类维生素 核黄素（维生素B2）
GB 7300.205-2025 is an upcoming mandatory Chinese national standard for Feed additives—Part 2：Vitamins, provitamins and chemically well-defined substances having similar effect—Riboflavin（Vitamin B2）. It appears in the Food compliance cluster with a product safety focus and has an implementation date of Sep 1, 2026.
Applicability depends on product scope, certification route, competent authority notices and transition rules. Requst for the translation or verify source before using this record in a compliance decision.
Compliance overview
Scope and applicability
This standard applies specifically to feed additive Riboflavin (Vitamin B2) obtained through biological fermentation. It is designed for manufacturers and distributors of vitamin premixes and animal nutrition products entering the Chinese market. It does not cover chemically synthesized Riboflavin or food-grade/pharmaceutical-grade Vitamin B2.
Technical requirements
This standard specifies comprehensive technical requirements for feed-grade Riboflavin, categorized into physicochemical and hygiene indicators. The physicochemical requirements define the acceptable purity range for different product grades (e.g., 96-type and 98-type), along with strict limits for specific optical rotation, lumiflavin (a degradation byproduct), loss on drying, and ignition residue. Compliance with these physicochemical boundaries is mandatory for batch release. Regarding safety, the standard enforces strict hygiene indicators to prevent heavy metal contamination in animal feed chains. It sets maximum concentration limits for total arsenic and heavy metals (calculated as Pb). Notably, this version replaces the previous standalone lead limit with a comprehensive heavy metals assessment.
Testing methods
The standard outlines rigorous testing procedures to verify product identity and quality. Identification methods include a fluorescence test and UV-Visible absorption spectroscopy. Quantitative and qualitative assessments involve spectrophotometric determination of Riboflavin content, polarimetry for specific optical rotation, and extraction methods for lumiflavin analysis. Heavy metal and arsenic levels must be evaluated using referenced national testing standards. GB/T 13079 and NY/T 4689 are specifically invoked for these safety evaluations.
FAQs
What products are regulated under GB 7300.205-2025?
This standard applies to feed additive Riboflavin (Vitamin B2) obtained through biological fermentation. It covers two product specifications: 96-type and 98-type.
Are there any updates from the previous version of GB 7300.205-2025?
The new standard replaces GB/T 7297-2006. Key updates include revised content ranges and calculation formulas for Vitamin B2, added testing procedures for lumiflavin, and the replacement of the lead hygiene limit with a broader heavy metals (as Pb) limit.
How does GB 7300.205-2025 differ from international standards for Vitamin B2?
While the core testing principles (such as spectrophotometry) are similar to international methods, GB 7300.205-2025 is a mandatory Chinese national standard tailored for domestic feed additive compliance. It references specific Chinese testing standards like GB/T 13079 for arsenic, requiring strict adherence for market access.
The summary above provides a high-level overview of GB 7300.205-2025. 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.
