酸枣仁保健食用油的开发研究

摘要

[目的] 研究开发一种可食用的酸枣仁保健油.[方法] 采用二氧化碳超临界萃取技术萃取酸枣仁油,然后通过分子蒸馏技术降低酸枣仁油的酸价与过氧化值,利用活性炭和白土的吸附特性进行脱色脱味处理.[结果] 试验得到一种淡黄色澄清、味道浅的酸枣仁油,测得其酸价为2.03 mg/g,过氧化值为4 mmol/kg;气相色谱分析检测结果得出:棕榈酸含量5.00%,硬脂酸含量2.00%,油酸含量40.46%,亚油酸含量47.72%,亚麻酸含量0.39%.[结论] 所得到的酸枣仁油基本上符合国家植物食用油卫生标准,可作为食用油使用,但其药理性质还需进一步研究.%[Objective] To research and develop spine date seed healthy edible oil.[Method] Spine date seed oil was extracted by supercritical carbon dioxide extraction technology.And then through the molecular distillation technology to reduce the acid value and peroxide value of spine date seed oil ,Using the characteristics of activated carbon and clay absorption,decolorization and deodorization treatment were carried out.[Results] A light yellow,clear,shallow taste spine date seed oil was obtained,the acid value was 2.03 mg/g,and the peroxide value was 4 mmol/kg;the GC indicated that the oil contains 5.00% palmitic acid,2.00% stearic acid,40.46% oleic acid,47.72% linoleic acid and 0.39% linolenic.[Conclusion]The obtained spine date seed oil basically conforms to the national edible oil standard and can be used as edible oil,but its pharmacological properties need further study.
