Most of enzymes are not used to completely degrade a substrate like endogenous amylase releasing glucose, but are more used to decrease the length of the polysaccharides to reduce impact on viscosity or accessibility for the &nbsp;endog enous enzymes.

Enzymes required to hydrolyse NSP from corn are endoxylanase, arabinofuranosidases, acetylxylan esterase, feruloyl esterase and glucuronidases.
