Enzyme Information


I.U.B. 9001-57-4


Sugar-breaking enzymes such as invertase break down disaccharides, trisaccharides and oligosaccharides that may cause gastric discomfort or dietary intolerances for some individuals.

The food grade invertase enzyme used in National Enzyme Company products is obtained by the controlled fermentation of Saccharomyces cerevisiae and is characterized by its ability to catalyze the inversion of sucrose solution. This enzyme catalyzes the hydrolysis of sucrose into its component parts D-fructose and D-glucose.


One Sumner Unit (SU) is defined as that quantity of enzyme that will convert 1 mg of sucrose to glucose and fructose in 5 minutes at a temperature of 20°C and a pH of 4.5. The amount of glucose and fructose produced is measured spectrophotometrically using a DNS acid- phenol reagent correlated to a glucose standard.


This enzyme is widely used to produce various confections and invert sugars as well as a digestive aid.
