Starch is first broken down into glucose molecules by α-amylase and amyloglucosidase. Next, glucose is converted to glucuronic acid and H2O2 by the enzyme glucose oxidase. Finally, H2O2 and ADHP are converted to the pink colored product resorufin and water by horse radish peroxidase.
Soluble starch is starch that is soluble when heated to 60°C. Resistant starch does not dissolve.
