Optimum environment. As with all enzymes, pectinases have an optimum temperature and pH at which they are most active. For example, a commercial pectinase might typically be activated at 45 to 55 Â°C and work well at a pH of 3.0 to 6.5. Pectinase is commonly used in fruit industries to speed up fruit juice extraction. Uses
Figure 1 shows that the optimum temperature of salivary amylase ranges from 32Â°C to 37Â°C.This applies to the human body since salivary amylase is suitable to function within these temperatures. After 37Â°C, the graph then steeply declines as a result of loss of activity. At 50Â°C and 70Â°C, salivary amylase is denatured.esults and Discussion The effect of temperature and pH on the enzymatic activity of salivary amylase was determined by measuring the rates of reaction in varying temperatures and pH. The 0.5% NaCl added in the enzyme solution activates the salivary amylase to perform its function â to hydrolyze starch.
