Patent ID: 8241685

Claim:
A saccharogenic method comprising: providing a milled or minced, extruded raw material, wherein the raw material was extruded in the presence of an enzyme; mixing the extruded raw material with water in a ratio of the extruded raw materials to water of 1:1.3 to 1:3.5 to create a slurry; adjusting a pH of the slurry to a range between 6.0 to 7.0; adding calcium ion, an acid reagent, α-amylase and glucoamylase to the slurry, wherein α-amylase and glucoamylase are added in an amount of 0.2 L to 1 L or 0.2 kg to 1 kg per ton of the extruded raw material; liquefying the slurry by raising a temperature of the slurry and holding the slurry at the temperature for 5 minutes to 70 minutes, wherein liquefying occurs between 65° C. and 100° C.; cooling the temperature of the slurry to 45° C. to 70° C.; adjusting the pH of the slurry to 3.8 to 5.5 by adding an acid reagent; saccharifying the slurry by adding calcium ion and 0.4 L to 2 L or 0.4 kg to 2 kg of glucoamylase per ton of the extruded raw material to the slurry and holding the slurry for several hours; inactivating any α-amylase and glucoamylase present in the slurry by adjusting the pH of the slurry to 4.5 to 5.5, heating the slurry to 80° C. to 95° C., and holding the slurry at 80° C. to 95° C. for 5 minutes to 70 minutes; cooling the slurry to 60° C. to 70° C.; and filtering the slurry to obtain a saccharification liquor.
