  • Method of measuring the deleterious effects of non-caloric artificial sweeteners on enzymatic hydrolysis of sucrose measured in real time
    Patent number: 10612071
    Abstract: Non-caloric artificial sweeteners (NAS) are used as a substitute for natural sugars by providing the sweet taste. This invention measures the effects of artificial sweeteners on the enzyme kinetics of biological systems. The claimed invention is directed to a method of measuring the effect of an artificial sweetener on enzyme-catalyzed hydrolysis of a sugar comprising establishing a first sugar enzymatic conversion rate, then determining a second sugar enzymatic conversion rate, and lastly comparing the first sugar enzymatic rate and the second sugar enzymatic conversion rate. The sugar enzymatic conversion rates can be measured by either nuclear magnetic resonance spectroscopy or a glucometer. The methodology presented may be applied to the elucidation of kinetic parameters for invertase catalyzed conversion of sucrose to glucose and fructose.
