NEUTRAL SUGAR CONTENTS OF CORN GLUTEN MEAL AND CORN GLUTEN FEED

Corn gluten meal and corn gluten feed are coproducts from wet milling of corn. To increase their potential for further processing, the carbo hydrate composition of these coproducts was determined. Each material was first hydrolyzed by trifluoroacetic acid, and the noncellulosic ne utral sugars were then measured by high-performance liquid chromatogra phy. Glycerol (3.7 and 4.9%), arabinose (0 and 6.1%), xylose (0.3 and 6.3%), mannose (1.0 and 0%), glucose (7.9 and 21.1%), and galactose (0 .2 and 1.7%) were found in corn gluten meal and corn gluten feed, resp ectively. Glycerol and glucose account for most of the neutral carbohy drates from the hydrolysis of the 80% methanol soluble fraction (monos accharide and low molecular weight oligosaccharides).
