摘要
探讨以燕麦麸为原料,用酶-碱结合工艺提取燕麦麸膳食纤维的可行性,并对影响燕麦麸膳食纤维提取的各因素进行了讨论。结果表明,在料水比1∶10,α-淀粉酶添加量1.5%,酶解溶液pH值7.0,酶解温度65℃条件下,酶解40min后,使用1mol/LNaOH溶液调节pH值至11,于60℃条件下反应30min,燕麦麸膳食纤维的提取率达66.124%。
The feasibility for extraction of dietary fiber from oat bran by the combined enzymatic and alkali technology was investigated, and the different factors affecting the extraction of dietary fiber were discussed. The optimal extracting conditions were as follows： the ratio of material to water was 1：10,α-amylase addition 1.5%, pH value 7.0 and enzymatic hydrolysis under temperature 65℃ for 40 min. The extracting rate of dietary fiber was up to 66. 124% when using 1 mol/L NaOH solution with pH value adjusted to 11 reacting under 60℃ for 30 min.
