Enzymolysis grain puree and preparation method thereof

The invention aims to provide a preparation method of enzymolysis grain puree. The method includes the following steps: performing shallow baking for grain raw materials; shattering and sieving the shallowly-baked grain raw materials at high dry-matter concentration, then performing low-temperature swelling at the temperature of 58 DGE C to 65 DGE C; performing enzymolysis for the raw materials obtained by low-temperature swelling at the temperature of 62 DGE C to 68 DGE C by adding amylase and glucoamylase; performing enzyme deactivation treatment for the obtained enzymatic hydrolysate and performing filtration, then obtaining the enzymolysis grain puree. The invention also provides the enzymolysis grain puree obtained by the preparation method of enzymolysis grain puree. 本发明的目的在于提供种酶解谷物原浆制备方法，其包括以下步骤：对谷物原料进行浅焙；在高干物质浓度下，对所述浅焙的谷物原料进行粉碎过筛，然后在58℃-65℃下进行低温溶胀；通过加入淀粉酶与糖化酶，在62℃-68℃下对所述低温溶胀后得到的原料进行酶解；对得到的酶解液进行灭酶并过滤，从而得到酶解谷物原浆。本发明还提供了使用该酶解谷物原浆制备方法得到的酶解谷物原浆。
