Abstract
Using enzymatic and chemical method to prepare corn bran dietary fiber from the corn bran.At the meantime using biological modification to modify the corn bran IDF,detecting the WBC to make sure the best modification condition.Compared with the raw materials,the WBC of the product after xylanase modification was 5.70g/g,the expansive force was 3.03mL/g,respectively increased 65.70% and 14.93%.The xylanase modification of optimum condition：pH 5.0,the amount of enzyme was 0.2mL/g,digesting in 55℃ water bath for 50min.The WBC of the product after cellulase modification was 5.83g/g,the expansive force was 2.73mL/g,respectively increased by 69.48% and 3.70%.The cellulose modification of optimum condition：pH 6.0,the amount of enzyme was 0.1mL/g,digesting in 45℃ water bath for 2h.The enzyme modification had a great effect on increasing the WBC,providing a new way for corn deep-processing.关键词
