GB/T 22346-2023 in English

1. Background of standard formulation and analysis of technological evolution

GB/T 22346-2023 "Chestnut Product Quality Grade" is a comprehensive revision based on the original standard GB/T 22346-2008, which mainly regulates the quality grading of my country's main high-quality chestnut products such as chestnut, Dandong chestnut and Castanea henryi. The new standard has made important adjustments in terms of scope expansion, term definition, physical and chemical indicators, and deleted the hygiene indicator requirements, focusing more on the technical requirements of the product quality itself.

Compared with the old version, the new standard adds the definition of "processed chestnut" and reclassifies the quality grades and physical and chemical indicators of chestnut. These changes fully take into account the development needs of my country's chestnut industry, especially its application in the field of processed food, and provide clear technical standards for chestnuts for different uses.
