Embodiment 1
[0021] Example 1 A kind of efficient and environment-friendly maltose syrup sugar production process, it comprises the following steps:
[0022] A. Starch mixing: Dilute the starch with hot water into starch milk with a concentration of 16Be. The temperature of the starch milk is less than or equal to 50°C. Adjust the pH value of the starch milk to 6.0. Add high-temperature resistant α-amylase to the starch milk. The addition of amylase is 400ml / ton of dry starch;
[0023] B. Liquefaction: The starch milk is liquefied by the second injection liquefaction method, the temperature of the first injection is 105°C, the temperature of the second injection is 125°C, and the flow rate of the two injections is 12m 3 / h, the DE value of the obtained liquid is 12%;
[0024] C. Saccharification: Cool the liquid obtained in step B to 58°C, adjust the pH value of the liquid to 5.5, and then add β-amylase, pullulanase and maltotriose hydrolase in an amount of 100ml / ton dry starch, Suga...
