摘要:

以花生茎为原料,微波提取花生茎中水溶性膳食纤维。通过对浸泡时间、微波时间、微波功率、微波温度和料液比等影响因素进行单因素及正交试验,获得花生茎水溶性膳食纤维的最佳提取工艺条件:浸泡时间55min、微波时间4min、微波功率800W、微波温度90℃、料液比1:14(g/mL),水溶性膳食纤维提取率达到6.0%,NSP 含量为94.68%,SDF 综合评分为65.12%。

Abstract:

In this study, peanut stems were used as the raw materials to extract soluble dietary fiber (SDF) through microwaveassisted technology. The optimal microwave-assisted extraction processing conditions were explored by single factor and orthogonal experiments through evaluating the effects of soaking time, microwave treatment time, microwave power, microwave treatment temperature and material-liquid ratio on extraction rate of SDF from peanut stems. Results indicated that the optimal microwaveassisted extraction processing conditions were soaking time of 55 min, microwave treatment time of 4 min, microwave power of 800W, microwave treatment temperature of 90 ℃ and solid-liquid ratio of 1:14. Under the optimal extraction conditions, the extraction rate of SDF was 6.0% and the content of non-starch polysaccharides (NSP) in SDF was 94.68%. The average comprehensive score of SDF was 65.12%. These studies can provide a theoretical reference for the extraction of SDF from peanuts stems.
