香菇柄水溶性膳食纤维饮料的研制

Preparation of Lentinus Edodes stem soluble dietary fiber beverage

以香菇柄为主要原料,采用纤维素酶法提取其中的水溶性膳食纤维,再与一些辅料进行科学调配,制成一种具有保健功能的膳食纤维饮料。通过单因素试验和正交试验确定了纤维素酶法提取水溶性膳食纤维的工艺条件,即纤维素酶浓度2.5 mg/mL,酶解温度55℃,酶解p H值5.0,酶解时间2.5 h。通过正交试验对产品的风味进行了调配,得出最优工艺配方为:白砂糖添加量7%,柠檬酸添加量0.15%,维生素C添加量0.03%,稳定剂添加量0.25%,在此条件下,可溶性固形物含量为12.6%,SDF含量为2.12%。

The production of soluble dietary fiber from Lentinus Edodes stem by enzymatic hydrolysis of cellulose was added of some ingredients to mix a kind of functional drinks. The best enzymatic hydrolysis conditions were studied by single factor experiments and orthogonal test. The results indicate that the optimum extraction technology is as follows： enzyme concentration 2.5 mg/mL, enzymatic temperature 55℃, enzymatic time 2. 5 h, enzymatic pH 5.0. The flavors of product were concocted by orthogonal array. The best recipe of product is as follows： White sugar 7%, citric acid 0.15%, Vitamin C 0.03%, stabilizer 0.25%. Under the conditions, soluble solid content is 12.6%, and the SDF content is 2.12%.
