Process for preparing starch hydrolyzate with high content of protein and maltose

摘要

Native cereal enzyme extract, rich in protein and minerals and contg. the protein as insol. gluten and soluble protein from the cereal flour, is hydrolysed, alone or in admixture with a starch suspension in ratio of 1:1-10 wt.%, and a dry matter content of 5-42 wt.%, with moderate stirring and for 1-14h, with addn. of an alpha-amylase, a proteinase and simultaneous utilisation of the natural cereal beta-amylase present in the medium. Hydrolysis is at 45-67 deg.C and pH 4.5-6.0, to 45.50 dextrose equiv. units.
