| 摘 要： | 通过调节亲水性溶剂乙醇使用量,考察乙醇浓度的变化对乙醚-石油醚提取微胶囊中DHA的影响,并对提取条件进行优化,使乙醚有效地提取脂肪,提高了微胶囊中DHA提取率。本提取方法与国标法的酸水解法(GB5009.6-85)和哥特里-罗紫法(GB/T5009.46-1996)比较,DHA的提取率提高了10%以上,本提取方法的回收率为97.0%-98.3%,且具有操作简便、不易出现乳化等优点。 |

| Abstract: | This study was designed to investigate the effects of changes in ethanol concentration on extraction of micro - capsulated DHA from health food and optimize the condition for the extraction.The rate of DHA extraction by this method was 10% more than that by the methods of GB5009.6-85 and GB/T5009.46-1996.The recovery was 97.0% - 98.3% .Meanwhile,this method is simple and accurate. |
