Enzyme Information


I.U.B. 37288-54-3


Fiber-breaking enzymes are capable of hydrolyzing the nondigestible carbohydrates that comprise fiber. The human body does not produce enzymes to break down fiber, but instead is at the mercy of enzymes produced by intestinal microorganisms. While fiber is an important part of a healthy diet, it may also act as an anti-nutritive factor. Fiber may bind to minerals and other nutrients, blocking their bioavailability and preventing their absorption.

The hemicellulase enzyme used in National Enzyme Company products is a food grade enzyme complex obtained by the fermentation of Aspergillus niger. Hemicellulase is a mixture of enzymes including polygalacturonate hydrolase, arabinosidase, mannosidase, mannanase and xylanase. It hydrolyzes the interior glucosidic bonds of galactomannoglucans, yielding polysaccharides of lower molecular weight.


One FCC Hemicellulase Unit (HCU) is that activity that will produce a relative fluidity change of one in five minutes in a locust bean gum substrate under the conditions of the assay. This assay is based on the enzymatic hydrolysis of the interior glucosidic bonds of a defined locust (carob) bean gum substrate at pH 4.5 and 40°C. The corresponding reduction in substrate viscosity is determined with a calibrated viscometer.


The primary use of this enzyme complex is in supplementing or modifying animal feeds to increase nutrient availability. This enzyme decreases the level of non-starch polysaccharides and their anti-nutritive effect. This enzyme has benefits for use in human and pet digestion as well as in agricultural feeds.
