Abstract

PURPOSE: Tubers or tuberous roots is pasteurized with an acid without steaming or boiling, ground and a composite enzyme preparation containing specific amounts of cellulase, hemicellulase and pectinase obtained from a strain in Aspergillus is made to act on the ground product to effect the liquefaction and saccharification.
CONSTITUTION: Raw sweet potatos and/or raw cassavas are washed, dipped in an acid solution and mechanically crushed. The liquefaction and saccharification of the crushed product is effected at room temperature to 50°C and 3.5W4.5pH using an enzyme composition containing cellulase of more than 300 units as CMCase every 1kg of the raw material, hemicellulase of more than 100 units as arabinogalactanase, pectinase of more than 400 units as the pectin viscosity reduction rate, glucoamylase of more than 1,500 units as starch saccharification rate and acidically active α- amylase of more than 20 units as the rate of starch-iodine coloring reduction.
