Hydrolysis rate of starch
WebUnder optimal conditions as much as 30 to 40 percent of ingested starches can be broken down to maltose by ptyalin during digestion in the stomach. When food passes to the small intestine, the remainder of the starch molecules are catalyzed mainly to maltose by pancreatic amylase. Web26 nov. 2024 · At 53oC, the time taken to digest the starch was longest at 286.7 seconds. At this temperature, the enzyme amylase has started denaturing and becoming inactive due to the high temperatures hence reducing its activity on the substrate starch hence reducing the rate of digestion. No color changes were observed above 59oC.
