饲料添加剂 第1部分：氨基酸、氨基酸盐及其类似物 牛磺酸
GB 7300.105-2025 is an upcoming mandatory Chinese national standard for Feed additives—Part 1：Amino acids,their salts and analogues—Taurine. 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 to feed additive Taurine produced by chemical synthesis using ethylene oxide or 2-aminoethanol as the primary raw materials, with or without a small amount of anti-caking agent. It is mandatory for manufacturers producing Taurine for the Chinese animal feed market. This document does not apply to naturally extracted Taurine or Taurine used in human food products, which are covered by GB 14759-2010.
Technical requirements
The standard outlines the chemical identification and physical properties of Taurine. It specifies that the product must appear as a white crystalline powder without odor. Identification must be confirmed using both thin-layer chromatography and infrared spectroscopy, ensuring consistency with standard reference samples. Furthermore, the standard sets strict physicochemical limits for parameters such as Taurine content (on a dry basis), pH value, crude ash, moisture, chlorides, sulfates, and ammonium salts. Manufacturers must ensure their products meet these precise physicochemical thresholds to pass compliance checks. It also defines hygiene parameters, specifically establishing maximum allowable limits for total arsenic and heavy metals (as Pb). These safety requirements are critical for animal health and feed safety regulations in China. Finally, the document provides rules for batch formation, factory inspection, and type testing. Compliance with both factory and type testing protocols is essential for market access. Packaging, labeling, transportation, and storage requirements must align with GB 10648.
Testing methods
The standard outlines several key testing procedures: - Identification: Thin-layer chromatography (TLC) and Infrared (IR) spectroscopy. - Taurine Content: Potentiometric titration or indicator-based titration using a sodium hydroxide standard solution. - pH Value: Measured using an acidometer according to GB/T 9724. - Physicochemical Parameters: Gravimetric and titrimetric methods for ash, moisture, chlorides, sulfates, and ammonium salts. - Hygiene Parameters: Specific chemical preparation and analysis methods for total arsenic and heavy metals.
FAQs
What products are regulated under GB 7300.105-2025?
