Megazyme Total Starch HK Assay Kit, 100 assays


A modification of AOAC Method 996.11, AACC Method 76-13.01 and RACI Standard Method for the measurement, and analysis of total starch in cereal flours and food products. This kit contains an improved α-amylase that allows the amylase incubations to be performed at pH 5.0 (as well as pH 7.0). The method has been further modified by adjusting the D-glucose determination to a hexokinase/glucose-6-phosphate dehydrogenase/NADP+ based format.


UV-method for the determination of Total Starch in grains,
animal feeds, foodstuffs and other materials

(α-amylase, 100°C + DMSO)
(1) Starch granules + H2O → maltodextrins

(2) Maltodextrins + H2O → D-glucose

(3) D-Glucose + ATP → G-6-P + ADP

(glucose-6-phosphate dehydrogenase)
(4) G-6-P + NADP+ → gluconate-6-phosphate + NADPH + H+
