Popis
BS EN ISO 6647-2:2020
This standard BS EN ISO 6647-2:2020 Rice. Determination of amylose content is classified in these ICS categories:
- 67.060 Cereals, pulses and derived products
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 %.
NOTE
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.
