Champ d’application

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.

Exigences techniques

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.

Méthodes d’essai

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.
