This standard BS EN ISO 6647-2:2020 Rice. Determination of amylose content is classified in these ICS categories:

This document specifies two simplified routine methods for the determination of the amylose mass fraction of milled rice, non-parboiled. The main difference between the two methods is the dispersion procedure: method A specifies hot dispersion, and method B specifies cold dispersion.
Both methods are applicable to rice with an amylose mass fraction higher than 5 %.
These methods describe simplified procedures for the preparation of samples, which are frequently used in routine laboratories. The methods use the same reagents as the reference method (see ISO 6647-1 ), but omit the defatting step. Rice samples where the amylose mass fraction has been determined by the reference method are used as standards.
