摘要
对水酶法提取花生油过程中产生的乳状液进行高压蒸汽破乳工艺研究。在单因素试验基础上,采用响应面分析法对高压蒸汽破乳工艺进行优化。确定最优破乳工艺条件为:蒸汽压力18.2MPa,蒸汽温度115℃,蒸汽处理时间21 s。在最优破乳工艺条件下,破乳率为93.49%,总油提取率为89.54%,并且高压蒸汽破乳效果明显优于水浴加热破乳。
High - pressure vapor demulsification of the emulsion produced by aqueous enzymatic extrac- tion of peanut oil was researched. Based on single factor experiment, the high - pressure vapor demulsifi- cation process was optimized by response surface methodology. The optimal demulsification process condi- tions were obtained as follows： vapor pressure 18.2 MPa, vapor temperature 115℃ and vapor treatment time 21 s. Under these conditions, the demulsification rate was 93.49%, and extraction rate of total oil was 89.54%. In addition, the high -pressure vapor demulsification effect was obviously superior to water bath heating demulsification.
