酶解技术在无添加糖类婴幼儿米粉中的应用

本文研究了无添加糖类婴幼儿米粉酶解后的DE值及其对辊筒干燥工艺产品的影响,选取α-淀粉酶4000 SG、常温、底物浓度50％、酶添加量0.0056％和酶解时间30 min作为最佳的酶解条件,并在此酶解条件下确定辊筒干燥工艺参数为蒸汽压力0.6 MPa,转速1000 r·min-1,验证了无添加糖类的婴幼儿米粉生产可行性...

Application of Enzymatic Hydrolysis Technology in Infant Rice Flour

In this study,the optimal enzymatic hydrolysis conditions ofα-amylase 4000 SG at room temperature,substrate concentration of 50%,enzyme addition amount of 0.0056%,and enzymatic hydrolysis time of 30 min were determined by the DE value of infant rice flour without adding sugar,and on this basis,the effect of roller drying was studied.Under the conditions of enzymatic hydrolysis,the roller drying process parameters were determined as steam pressure 0.6 MPa and rotational speed 1000 r·min^-1,which realized the feasibility of producing infant rice flour without adding sugars,and the product yield was increased to 70%.
