Comparison of almond β-glucosidase activity measured at 400 and 405 nm. Measured in a reaction containing phosphate buffer or phosphate buffer with 25 μL of heat-inactivated human saliva. Enzyme activity was measured in both the inactive saliva and phosphate buffer at 400 nm (■, □) and 405 nm (░, ▓), respectively. The rate of reaction displayed on the y-axis in units of change in absorbance per change in time (minutes). The data points represent average values ± SD
