Escopo e aplicabilidade

This standard applies to the feed additive Calcium L-ascorbate produced chemically from L-ascorbic acid and calcium salts. It specifies the technical requirements, testing methods, and labeling for this specific vitamin-type additive used in animal feed. Manufacturers of vitamin feed additives must comply with this standard before entering the Chinese market. It replaces the previous GB 34463-2017.

Requisitos técnicos

The standard outlines the physical and chemical specifications for Calcium L-ascorbate. It requires the product to be a white or pale yellow crystalline powder, soluble in water. Identification must be confirmed through both chemical reactions and infrared spectroscopy, matching the standard reference spectrum. Compliance with the specified physicochemical and hygiene limits is mandatory for product approval. The technical parameters cover purity levels, drying loss, specific rotation, and pH value for a 10% aqueous solution. Additionally, the standard sets strict hygiene indicators including maximum limits for total arsenic, lead, and fluoride to ensure feed safety. Packaging materials must be light-proof, non-toxic, and moisture-proof, adhering to the labeling requirements of GB 10648.

Métodos de ensaio

Testing procedures include visual and olfactory inspection for appearance, and specific chemical assays for identifying calcium and ascorbate ions. Infrared spectrophotometry is utilized for structural confirmation. The primary assay for Calcium L-ascorbate content is performed using an iodometric titration method. Strict precision requirements must be followed during these analytical procedures. Heavy metal and mineral content (arsenic, lead, fluoride) are tested according to referenced national methods such as GB/T 13079 and GB/T 13080.

Perguntas frequentes
