Escopo e aplicabilidade

This standard applies to feed additive sodium glutamate manufactured from carbohydrates such as starch, corn, and molasses through microbial fermentation using Corynebacterium glutamicum. It is mandatory for manufacturers producing this specific feed additive in China. It does not apply to other types of flavouring or appetising substances.

Requisitos técnicos

The standard specifies the physical and chemical requirements for sodium glutamate. Appearance must be colorless to white crystalline particles or powder with a specific umami taste. Identification must comply with the ninhydrin test and sodium salt test. Key technical indicators include limits for sodium glutamate content (on a dry basis), loss on drying, transmittance, specific rotation, chloride, pH value, sulfate, total arsenic, and lead. Compliance with these specific parameter limits is essential for market access.

Métodos de ensaio

Testing methods include sensory inspection for appearance and taste, and chemical identification tests. Quantitative analysis involves spectrophotometry for transmittance, polarimetry for specific rotation, and Nessler colorimetry for chloride. pH is measured using an acidimeter, and sulfate is determined via barium chloride turbidimetry. Heavy metals like total arsenic and lead are tested according to GB/T 13079 and GB/T 13080. Manufacturers must ensure all testing adheres to these specified methodologies.
