Basic Information
Scope
Main technical content: The processing quality requirements of this standard are divided into high-quality grade I and high-quality grade II. Based on the high-quality japonica rice grade I and grade II indicators in GB/T 1354-2018 "Rice", and combined with the results of sampling inspection, the corresponding requirements for high-quality japonica rice grade I and grade II in GB/T 1354-2018 "Rice" have been raised, and they are determined as the high-quality grade I and high-quality grade II indicators of this standard. The broken rice, processing precision, chalkiness, tasting score, amylose content, moisture content, unperfect grain content, impurity limit, yellow grain content, and mixing rate in this standard are formulated according to the high-quality japonica rice grade I and grade II indicators in GB/T 1354-2018 "Rice". According to the results of sampling inspection, the high-quality grade I and high-quality grade II indicators in this standard are higher than the requirements for high-quality japonica rice grade I and grade II in GB/T 1354-2018 "Rice"; the yellow grain content and unperfect grain content in high-quality grade I exceed the requirements for high-quality japonica rice grade I in GB/T 1354-2018 "Rice", and the high-quality grade II exceeds the requirements for high-quality japonica rice grade II in GB/T 1354-2018 "Rice". The amylose content is adjusted to 18% to 20% according to the results of sampling inspection, which meets the range requirements of 13.0% to 20.0% in GB/T 1354-2018 "Rice". The moisture content is adjusted to not more than 15.5% according to the results of sampling inspection, which meets the range requirements of not more than 15.5% in GB/T 1354-2018 "Rice". The color and odor requirements are specified according to the sensory indicators in GB/T 1354-2018 "Rice".
