摘　　要：该研究以双低菜籽为原料,乙醇溶液为溶剂,在超声波辅助下萃取制备双低菜籽浓缩蛋白;由单因子实验确定最佳工艺参数为:超声频率20DHz,超声功率100 KW,乙醇溶液浓度70％, 液固比3．5:1,萃取3次,每次20 min,得到浓缩蛋白产品蛋白含量大于60％,氨基酸平衡;硫甙、植酸、单宁等杂质去除85％以上。Preparation of protein concentrates assisted by ultrasound from Canola seed are studied. After investigating the single effect factor on protein preparation, the optimum factors were as follows：the concentration of ethanol 70%, the rate of solution to solid 3.5 to 1, pH3.5, and extracting three times, with 20min each, under 100kw ultrasound power, The result showed that protein contents are above 60% and contain a balanced amino acids profile, impurities such as phytic acid, glucosinolate content and tannin are removed more rather 85%.
