采用微波辅助技术从脱酚棉籽粕中提取棉籽糖,通过单因素和正交实验考察了微波处理时间、微波功率、料液比、pH 值对棉籽糖浸出率的影响,得出了棉籽糖最佳提取条件：微波处理时间9 min、微波功率650 W、料液比1∶10、pH 值2．5,在此条件下棉籽糖的浸出率为91．5％,经过微滤膜除杂和纳滤膜浓缩纯化后,棉籽糖纯度95％.最后,通过微滤膜和纳滤膜技术进一步纯化浓缩棉籽糖.

The microwave-assisted technology was employed to extract raffinose from cottonseed meal without gossypol.Effects of microwave time,microwave power ratio,material liquid ratio and pH value on extraction rate of raffinose by the single factor and orthogonal experiments were studied.The best ex-tract conditions of raffinose were obtained.Raffinose was purified by micro-filtration membrane and nano-filtration membrane technology.The results showed that the best extract conditions were:microwave time 9 min.,microwave power ratio 650W,material liquid ratio 1:10,pH=2.5.In these conditions,the extrac-tion rate of raffinose was 9 1 .5%.After purification by micro-filtration membrane purifying and nano-filtra-tion membrane enrichment,the purity of raffinose was 9 5%.
