Aperçu de conformité

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

Champ d’application

This standard applies specifically to feed additive bile acids derived from porcine bile extract. It is applicable to products obtained through specific processing techniques including saponification, decolorization, acidification, purification, and drying. The standard is intended for manufacturers and regulatory bodies involved in the animal nutrition and livestock feed industry.

Exigences techniques

The standard outlines the chemical identities of the main active components: hyocholic acid, hyodeoxycholic acid, and chenodeoxycholic acid. It establishes stringent physicochemical parameters for the final product, including minimum content limits for total bile acids and specific component ratios, as well as maximum thresholds for moisture, crude ash, and particle size. Furthermore, it sets critical hygiene and safety limits for heavy metals (such as arsenic, lead, and cadmium) and microbial contaminants like Salmonella. Compliance with these technical requirements is mandatory for market access.

Méthodes d’essai

The standard prescribes specific analytical procedures for quality verification. Identification tests rely on characteristic color reactions in sulfuric acid-formaldehyde solution. Quantitative analysis of the active components is primarily conducted using High-Performance Liquid Chromatography (HPLC), detailing both fluorescence detection (as the arbitration method) and refractive index detection. Heavy metal and microbial testing strictly follow referenced national standards such as GB/T 13079 for arsenic and GB/T 13091 for Salmonella.

Questions fréquentes

What specific products are regulated under GB 7300.1301-2025?

This standard regulates bile acids used as feed additives, specifically focusing on the content of hyocholic acid, hyodeoxycholic acid, and chenodeoxycholic acid. It applies to products derived from pig bile paste.

Are there any updates or new implementations for GB 7300.1301-2025?

It is a newly released standard that will become mandatory on July 1, 2026. It establishes the first official product standard for bile acids under the "Others" category of the GB 7300 series, setting strict limits for heavy metals and microbial contamination.

How does GB 7300.1301-2025 differ from general ISO feed standards?

The standard defines specific physicochemical and hygiene parameters for bile acids extracted from porcine sources. It mandates strict testing for heavy metals like arsenic, lead, and cadmium, as well as the absence of Salmonella. Manufacturers must also adhere to specific labeling and packaging requirements under GB 10648.
