采用碱性热处理结合酸诱导热变性,从菜籽粕加工废水中回收蛋白质。经单因素实验和正交实验得出最优工艺条件为:热处理pH 10,热处理温度70℃,热处理时间10 min,酸沉pH2.5。在最优工艺条件下,所得蛋白质回收率和干基蛋白质含量分别达到62.11%和65.48%。

　　To improve the economic feasibility and environmental friendliness of rapeseed meal processing and utilization,a process for protein recovery from rapeseed meal processing wastewater (RMPW) was developed.Analyses of particle size distribution and differential scanning calorimetry revealed that the dissolved protein in RMPW could be effectively precipitated with acid-induced denaturization,while the protein associated with the emulsified oil could be released by heat treatment in alkali condition.Based on these observations,the recovery proc...
