WebThey break down complex molecules into simple ones. In this case, amylase converts starches (complex molecule) into simple sugars. That is why foods like potatoes for example, may taste sweet to us, because they contain starch. The optimum pH for pancreatic amylase is the pH of 7. WebFor homebrewers, we are concerned with the activity of two primary enzymes in beer: alpha- and beta-amylase. Alpha-amylase breaks down large, complex, insoluble starch molecules into smaller, soluble …

WebThis pH range is slightly basic and is similar to the pH of human saliva, which is why amylase is active in the mouth during the process of digestion. At pH values outside of this optimal range, the activity of alpha-amylase decreases significantly. Beta-amylase has an optimal pH range of 4.5 to 5.5, with the highest activity at pH 5.0. WebHis study showed that with the help of α-amylase, starch could be hydrolyzed at temperatures where the reaction would not normally occur. Ibrahim et al. (2004) varied …
