How is freezing/boiling amylase relevant to food preparation?
Got to love the science of enzymes and cooking. It catalyzes the breakdown of starch. When amylase reacts with starch, it cuts off the disaccharide maltose (two glucose molecules linked together). As the reaction progresses, less starch will be present and more sugar (maltose) will be present. Freezing retards the reaction, boiling/ heating advances.
