BS EN ISO 6647-2. Rice. Determination of amylose content. Part 2. Routine method: Spectrophotometric routine method without defatting procedure and with calibration from rice standards
67.060 - Cereals, pulses and derived products
This Annex 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, and method B 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 of which the amylose mass fraction has been determined by the reference method are used as standards.
