GB/T 23375-2009

This standard specifies the analytical methods for determining the content of copper, iron, zinc, calcium, magnesium, and phosphorus in vegetables and their processed products. It is applied in food quality control and safety testing laboratories to ensure nutritional labeling accuracy and monitor mineral contamination in raw vegetables, canned vegetables, dried vegetable powders, and vegetable-based baby foods. The standard is particularly relevant for compliance with Chinese food safety regulations and international trade requirements for vegetable-derived products.
