| 摘 要： | 为了降低苹果籽油的酸价,以压榨法毛油为试材,进行碱炼脱酸工艺研究,在单因素试验基础上,采用Box-Behnken设计响应面法优化碱炼脱酸工艺条件。结果表明:NaOH质量分数21%,中和温度50.5℃,中和时间39min,搅拌速度30r/min,在此条件下,苹果籽油酸价可达到0.91mgKOH/g。碱炼后的苹果籽油在脱胶、脱色、脱蜡精炼过程中,脱胶处理对苹果籽油的酸价影响显著。 |

| Abstract: | In order to decrease acid value (AV) of Apple seed oil, apple seeds oil btained by cold pressing was used to study the influence of the neutralization conditions on the AV .The optimization conditions for apple seed oil deacidification by response surface method (RSM) was performed. The result showed that the optimum parameters were: concentration of sodium hydrate 21 %, 50.5℃, 39min, agitation rate 30r/min. The acid value of apple seed oil was 0.91mgKOH/g. Degumming process greatly influenced the acid value of apple seed oil during refining process. |
| Keywords: | apple seed oil deacidification response surface method (RSM) optimization |
