Embodiment 1
[0023] (1) Slurry mixing, enzyme immersion and liquefaction: use cornstarch and water as raw materials for slurry mixing, adjust to a concentration of 15°Be, and stir for 20 minutes; the material liquid enters the enzyme immersion tank, adjusts the pH to 6.0, and adds high temperature resistant α -Amylase 0.35L / ton of dry starch, stirring and soaking for 15 minutes; liquefied by the first injection at 106°C, and liquefied by the second injection at 125°C after 65 minutes of heat preservation to a DE value of 14.5%;
[0024] (2) Saccharification and glucoside conversion: adjust the pH of the liquefaction liquid to 5.1, and the temperature is 60°C, add 160ml / ton of dry starch with β-amylase and 150ml / ton of dry starch with pullulanase, inactivate the enzyme after 25 hours of heat preservation; adjust the pH To 4.2, add transglycosidase of 0.35% of the dry starch mass, and react for 32 hours at a temperature of 58°C;
[0025] (3) Decolorization, filtration, separation, and concen...
Embodiment 2
[0028] (1) Slurry mixing, enzyme immersion and liquefaction: use cornstarch and water as raw materials for slurry mixing, adjust to a concentration of 17°Be, and stir for 20 minutes; the material liquid enters the enzyme immersion tank, adjusts the pH to 5.8, and adds high temperature resistant α -Amylase 0.45L / ton of dry starch, stir and soak for 15 minutes; liquefy with the first spray at 107°C, and liquefy with the second spray at 128°C after 70 minutes of heat preservation until the DE value is 15%;
[0029] (2) Saccharification and glucoside conversion: adjust the pH of the liquefaction solution to 5.2, the temperature is 56°C, add 180ml / ton of dry starch with β-amylase, 170ml / ton of dry starch with pullulanase, inactivate the enzyme after 26 hours of heat preservation; adjust the pH To 4.3, add 0.4% dry starch mass transglycosidase, temperature 59°C, react for 33 hours;
[0030] (3) Decolorization, filtration, separation, and concentration: add 0.025% activated carbon, h...
