    摘要:

    采用吸附脱色法对青海胡麻籽油进行脱色,并以波长665 nm下脱色率为指标,分别研究了脱色温度、脱色时间、吸附剂添加量三个因素对胡麻籽油脱色效果的影响。在单因素基础上进行三因素三水平响应面优化设计。结果表明,胡麻籽油脱色工艺的优化条件为:脱色温度为71 ℃、脱色时间为23 min、吸附剂用量为4.3%,脱色率达到77.59%。

    Abstract:

    The decolorization of Qinghai flaxseed oil was carried out by the method of adsorption decolorization. The decolorization rate at wavelength of 665 nm was selected as the experiment indicator, and the effects of 3 single-factors (decolorization temperature, decolorization time and addition amount of adsorbent) on the decolorization process were studied. On the basis of single - factors experiment, 3-variable 3-level response surface methodology were conducted to optimize the decolorization process. The results showed that the optimum conditions of the decolorization process were as follows: the decolorization temperature was 71 ℃, the decolorization time was 23 minutes, the amount of adsorbent was 4.3%, and the decolorization rate was 77.59%.
