商品描述 The Resistant Starch Test kit for the measurement and analysis of resistant starch in plant materials and starch samples.

Colourimetric method for the determination of Resistant Starch in cereal products and feeds Principle: (α-amylase + amyloglucosidase) (1) Non-resistant starch + H₂O → D-glucose + maltose (trace) (2) Aqueous ethanol wash + centrifugation to remove D-glucose + maltose (3) Dissolution of resistant starch pellet in KOH and neutralisation (α-amylase + amyloglucosidase) (4) Dissolved resistant starch + H₂O → D-glucose (glucose oxidase) (5) D-Glucose + H₂O + O₂ → D-gluconate + H₂O₂ (peroxidase) (6) 2H₂O₂ + p-hydroxybenzoic acid + 4-aminoantipyrine → quinoneimine + 4H₂O

Kit size: 100 assaysMethod: Spectrophotometric at 510 nmReaction time: ~ 120 min (plus overnight incubation)Detection limit: 2-100% of sample weightApplication examples: Plant materials, starch samples and other materialsMethod recognition: AOAC (Method 2002.02), AACC (Method 32-40.01) and CODEX(Type II Method)
