【摘要】 以稳定米糠为原料,利用物理方法和生物技术方法相结合,获得米糠营养提取液。经单因素和正交试验确定最佳提取工艺:采用二次提取,糠水比为1∶4;乳化剂蔗糖脂肪酸酯(SE13)的用量为0.4%;纤维素酶的用量为4%,反应温度为50℃,pH值为5.5,超声波提取2 h,米糠营养物提取率为47.8%,所得提取液中营养成分丰富。更多还原

【Abstract】 Stabilized rice bran was used as raw material,and the nutrients were extracted from rice bran by physical method in combination with biologic method.The optimum extraction process was determined through the single factor and orthogonal experiments: using the second extraction,bran-water ratio 1:4,the dosage of sucrose fatty acid ester as an emulsifier(SE13) 0.4%,reaction temperature 50 ℃,pH value 5.5,ultrasonic extraction 2 h.Nutrient extraction rate 47.8%,and the obtained extract was rich in nutrients.更多还原
