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. |
