MIIT released industry standards for corn deep-processing products 01-29-2024

Summary: The MIIT approved and released 1,276 industry standards including those for some corn deep-processing products in late Dec. 2023.

On 29 Dec., 2023, the Ministry of Industry and Information Technology of the People's Republic of China (MIIT) announced that 1,276 industry standards were approved and released, including those for some corn deep-processing products such as amino acids, enzyme preparations, acidulants and yeast.

 

These standards, which will take effect on 1 July, 2024, stipulate the sensory requirements, physical and chemical specifications, safety parameters, testing rules and requirements for labels, packaging, transportation and storage, and specify analytical methods, chemical names, molecular formulas, etc. for corresponding products.

 

For the industry standards for amino acids and an amino acid derivative please refer to the article "MIIT approves industry standards for three amino acids and one derivative" in Amino Acids China E-News 202401.
