Abstract

This report is an account of the pilot plant studies on cooking and thinning of corn starch with free α-amylase and the conversion of the resulting dextrin to glucose with glucoamylase immobilized to porous silica. Previous pilot plant work, in which dextrin produced by acid hydrolysis was further hydrolyzed to glucose with immobilized glucoamylase, has been reported elsewhere (1). Mainly emphasized here is the effect of feed composition on the rate of intraparticle diffusion and the effect of enzyme immobilization on the reactor selectivity.
