摘要
Abstract
[objective] To study extraction technology of isoflavone from soybean by microwave assisted and ethanol extraction method. [ Method] Isoflavonoids were extracted from soybean with alcohol as extractant assisted by microwave. Based on single factor analysis and orthogonal test,alcohol concentration,solid-liquid ratio,microwave time,extraction temperature and extraction time were investigated on the effect of soybean isoflavone extraction amount. [Result] The optimum extraction technology of isoflavone was as follows: alcohol concentration of 80% , solid to liquid ratio of 1:16 g/ml, microwave time of 4 rain, extraction temperature of 70℃ and extraction time of 2 hours. Under the condition, the extraction amount of soybean isoflavone was 25. 37 mg (20 g defatted soybean powder). [Conclusion] The extraction technology was simple and feasible with higher extraction amount.关键词
