Scope
Main technical content: This document specifies the determination of the content of amylose and amylopectin in barley—the terms and definitions, principles, reagents and materials, instruments and equipment, analysis steps, data processing, result presentation, and precision of the dual-wavelength spectrophotometry method. This document is applicable to the determination of amylose (detection limit: 0.249 g/100 g; quantitative limit: 0.753 g/100 g) and amylopectin (detection limit: 0.162 g/100 g; quantitative limit: 0.492 g/100 g) in barley.
