摘要:

以挤压豆渣为原料,采用热水浸提、超声波和微波辅助提取豆渣中水溶性大豆多糖。结果表明:热水浸提、超声波和微波辅助提取大豆多糖得率分别为3.45%、8.67%、11.60%。与传统热水浸提法相比较,采用超声波和微波辅助提取大豆多糖具有安全、节能、快速、得率高等优点。

Abstract:

Extruded soybean dregs were used as the raw material for extracting polysaccharide by hot water extraction, ultrasonicassisted extraction or microwave-assisted extraction. Optimal hot water extraction technology was investigated using single factor method, and optimal ultrasonic-assisted extraction and microwave-assisted extraction technologies using single factor method coupled to orthogonal array design for maximizing polysaccharide yield. Results showed that optimized hot water extraction, ultrasonic-assisted extraction and microwave-assisted extraction gave polysaccharide yields of 3.45%, 8.67% and 11.60%, respectively. In comparison with conventional hot water extraction, other two methods have the benefits of safety, saving energy, rapidity, high productivity, and so on.

Key words: extruded soybean dregs, ultrasonic, microwave, extraction, polysaccharide
