标准范围

本文件规定了测定未经蒸煮的精米直链淀粉含量的参考方法。该方法适用于直链淀粉质量分数大于5%的大米。本文件也可用于糙米、玉米、小米和其他谷物，前提是该范围的扩展已经过用户验证。注:本文件确定的直链淀粉值可与PDO和PGI法规进行比较。

This document specifies a reference method for the determination of the amylose content of milled rice, non-parboiled. The method is applicable to rice with an amylose mass fraction higher than 5 %.This document can also be used for husked rice, maize, millet and other cereals if the extension of this scope has been validated by the user.NOTE Amylose values determined with this document can be compared with PDO and PGI legislation.
