The objectives are to Procedure: Describes step-by-step procedures for conducting the experiments related to starch digestion by saliva. Carbohydrates are not chemically Introduction: In the first digestive reaction of starch, a disaccharide called maltose is produced. As food enters the mouth, the enzyme catalyses the hydrolysis of starch into simpler sugars like maltose. Mechanical and biochemical transformations occurring throughout oral, gastric and intestinal phases The procedures describe testing starch solutions with saliva at different temperatures and pH levels using iodine to observe changes in color as a result The following experiment will use various digestive enzymes and environmental conditions to examine the chemical digestion of foodstuff macromolecules The digestion of a carbohydrate such as starch begins in the mouth, where is it mixed with saliva containing the enzyme salivary amylase. Saliva and different starch/iodine mixtures were tested. Take the original C and D tubes and add enough drops of Benedict’s solution to color the contents a clear light blue. Digestion is the process by which your body changes the food you eat to forms that your body can use for repair, building, and energy. BACKGROUND Most animals begin their digestion in their mouths. In humans, the production of maltose from starch Investigatory project on starch digestion by salivary amylase, exploring the effects of temperature and pH.
