| 中文摘要: |
| 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pH 2.5。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%。 |
| 英文摘要: |
| The recovery of protein from rapeseed meal processing wastewater was investigated by alkali heat treatment and acid-induced heat denaturization.The optimal recovery conditions were obtained by orthogonal experiment based on single factor experiment as follows: heat treatment pH 10, heat treatment temperature 70℃，heat treatment time 10 min, acid precipitation pH 2.5. Under these conditions,the recovery rate of protein and the content of protein （dry basis）were 62.11% and 65.48%,respectively. |
