Aperçu de conformité

Cet aperçu n’est actuellement disponible qu’en anglais.

Champ d’application

This standard applies to feed additive DL-α-Tocopheryl acetate (powder form), which is manufactured using DL-α-Tocopheryl acetate as the raw material combined with approved carriers and excipients. It is strictly designed for the animal feed industry and mandates that all carriers and excipients must comply with the relevant Chinese Feed Raw Material Catalog and Feed Hygiene Standard.

Exigences techniques

The standard outlines specific physical and chemical parameters for the powder. It dictates that the product must appear as an off-white or light yellow powder, and sets strict minimum content limits for the active DL-α-Tocopheryl acetate ingredient. Additionally, it regulates physical characteristics such as drying loss and particle size distribution to ensure proper handling and mixture in feed formulations. Safety and purity are also heavily regulated, with defined maximum thresholds for heavy metals (calculated as Lead) and total arsenic (As). These contaminant limits are mandatory to ensure animal safety and prevent toxic accumulation in the feed chain. Furthermore, the standard provides specific guidelines for labeling, packaging, transportation, and storage. Packaging must be sealed and light-resistant, and the product must be stored below 25°C in a dry, ventilated, and dark environment. The shelf life is distinctly categorized based on the carrier type: 12 months for organic excipient carriers and 36 months for inorganic excipient carriers.

Méthodes d’essai

The standard prescribes several analytical procedures, including sensory evaluation for appearance and chemical identification using a colorimetric reaction with nitric acid. The primary assay for active content is determined via gas chromatography (GC) using a capillary column and an internal standard (cetyl palmitate), which serves as the arbitration method. An alternative high-performance liquid chromatography (HPLC) method is also provided. Additionally, it outlines specific gravimetric and comparative methods for determining drying loss, particle size, heavy metals, and total arsenic.

Questions fréquentes

What products are regulated under GB 7293-2017?

This standard regulates feed additive DL-α-Tocopheryl acetate (powder form), which is manufactured using DL-α-Tocopheryl acetate as the raw material along with approved carriers and excipients. It is specifically designed for the animal feed industry.

Are there any significant updates from the previous version of GB 7293?

The standard was upgraded from a recommended to a mandatory national standard. Key updates include adding requirements for carriers and excipients, updating the chemical name, changing the gas chromatography internal standard to cetyl palmitate, and classifying the shelf life based on carrier types (12 months for organic, 36 months for inorganic).

How does GB 7293-2017 relate to international standards?

The standard references Chinese national standards such as GB/T 601 and GB 10648 for reagents and labeling. While the testing methodologies (gas and liquid chromatography) align with general international practices, manufacturers must strictly adhere to the specific operational parameters and limits set within this GB standard for Chinese market compliance.
