Alcance y aplicabilidad

This standard applies to the feed additive DL-α-Tocopheryl acetate obtained by chemical synthesis using isophytol as the main raw material. It specifies the requirements, test methods, inspection rules, labeling, packaging, transportation, and storage for this product. It is mandatory for all manufacturers producing or exporting this feed additive to the Chinese market. The standard replaces the previous GB/T 9454-2008.

Requisitos técnicos

The standard outlines the physical and chemical requirements for DL-α-Tocopheryl acetate. It specifies that the product should be a micro-greenish-yellow or yellow viscous liquid, almost odorless, and gradually darkening upon light exposure. Key technical parameters include the minimum content of DL-α-Tocopheryl acetate, specific optical rotation, refractive index, and absorption coefficient. Manufacturers must strictly adhere to the specified limits for acidity, free tocopherol, heavy metals (as Pb), and total arsenic. The standard also defines the mandatory factory inspection items, including appearance, content, refractive index, specific rotation, absorption coefficient, acidity, and free tocopherol.

Métodos de ensayo

The standard details several testing methods to verify compliance. Identification tests include colorimetric reactions and Infrared (IR) spectrophotometry. The content of DL-α-Tocopheryl acetate is determined using Gas Chromatography (GC) as the arbitration method, or alternatively, High-Performance Liquid Chromatography (HPLC). Other tests include measuring refractive index using an Abbe refractometer, determining the absorption coefficient via UV spectrophotometry, and titration methods for acidity and free tocopherol. Heavy metals are evaluated using a thioacetamide colorimetric method, and total arsenic is determined using a silver diethyldithiocarbamate colorimetric method.

Preguntas frecuentes

What products are regulated under GB 9454-2017?

GB 9454-2017 regulates the feed additive DL-α-Tocopheryl acetate (Vitamin E acetate) produced via chemical synthesis using isophytol as the primary raw material.

Are there any updates from the previous version of GB 9454-2017?
