GB/T 5009.51-2003

This standard specifies the analytical methods for determining the hygienic indicators of nonfermented bean products (such as tofu, dried tofu, and tofu skin) and gluten products. It is applied in food safety testing laboratories and quality supervision contexts to assess parameters like microbial limits, food additives, and contaminants in these specific plant-based protein foods. The methods ensure compliance with China's national hygiene standards for production, sale, and import inspection of these products.
