Escopo e aplicabilidade

This standard applies to feed additives derived from Saccharomyces cerevisiae produced through liquid fermentation, dehydration, and drying. It is mandatory for all manufacturers producing and selling this specific yeast feed additive in China. It does not cover other types of microbial feed additives or inactive dry yeast products.

Requisitos técnicos

The standard specifies the technical requirements for Saccharomyces cerevisiae feed additives, covering appearance, strain identification, and physicochemical parameters. Manufacturers must ensure the product meets specific limits for viable yeast cell count and moisture content. It also outlines strict hygiene indicators to ensure product safety. Compliance with maximum limits for heavy metals such as lead, arsenic, mercury, and cadmium is strictly enforced. Additionally, the product must be free from Salmonella contamination. Compared to the previous version, this standard updates the requirements for appearance, viable cell count, and hygiene indicators. It also introduces a new plate method for detecting viable yeast cells, providing a more accurate assessment of product quality.

Métodos de ensaio

The standard references several testing methods to verify compliance. Strain identification is conducted using morphological, physiological, biochemical, and molecular biology methods as detailed in Annex A. The determination of viable yeast cell count can be performed using either the plate method or the staining method, with the plate method serving as the arbitration method. Moisture content and heavy metal contaminants are tested according to referenced national standards such as GB/T 6435 and GB/T 13080.
