Heat and pH Stability of Alkali‐Extractable Corn Arabinoxylan and Its Xylanase‐Hydrolyzate and Their Viscosity Behavior

Abstract

Arabinoxylan extracted by an alkali from corn bran is a soluble fiber with a desirable low initial and extended fermentation property. Corn arabinoxylan hydrolyzate using an endoxylanase was much more stable at different levels of acidity and heat than the native arabinoxylan, and showed lower solution viscosity and shear-thinning property that indicates its potential as an alternative functional dietary fiber for the beverage industry.
