微波、纤维素酶预处理对大豆低聚糖提取的影响

Influence of Microwave and Cellulose Pretreatment on the Extraction of Soybean Oligosaccharides

摘要:

以脱脂豆粕为原料，在碱液浸提法提取大豆低聚糖的最佳工艺条件（在55℃和pH为11的条件下浸提1h）的基础上，采用微波和纤维素酶分别对脱脂豆粕进行预处理，考察两种方法对大豆低聚糖提取率的影响。实验结果表明：微波处理后大豆低聚糖的提取率有所下降，而经纤维素酶处理后，低聚糖的提取率有显著提高。

Abstract:

Before the extraction of soybean oligosaccharides from defatted soybean meal under the optimal conditions (the pH value, extracting time and extracting temperature being of 11, 60min and 55℃, respectively), microwave and cellulose were used to pre-treat the defatted soybean meal. The results show that pretreatment of the material with microwave can decrease the extraction rate, while cellulose pretreatment can improve the extraction rate.
