CN107927200A 一种高油酸低酸值玉米葵花调和油及其制备方法 无效 - 驳回

一种高油酸低酸值玉米葵花调和油及其制备方法
摘要：
本发明公开了一种高油酸低酸值玉米葵花调和油，包括下列质量配比的原料：玉米胚芽30-45％，葵花籽30-45％，油茶籽10-20％，油橄榄10-20％，以及辣木籽5-15％。本发明经过多级分离超临界CO2萃取及分子蒸馏精炼。多级分离超临界CO2萃取既保有较高的提取率，又因多级分离的存在可同时分离水分、游离脂肪酸、臭味成分及色素成分等。再通过分子蒸馏技术进行精炼处理，即得高油酸低酸值的玉米葵花调和油，其出油率可达30％以上，酸价低于0.35(KOH)/(mg/g)，不饱和脂肪酸含量92％以上，油酸含量55％-65％。本发明不仅弥补了玉米油和葵花油油酸含量较低的缺陷，还实现了油脂的快速精炼，大大降低了所得调和油的酸值。
摘要（英）：

The invention discloses corn and sunflower seed blend oil with a high oleic acid content and a low acid value. The corn and sunflower seed blend oil comprises the following raw materials in percentageby mass: 30-45% of corn germs, 30-45% of sunflower seeds, 10-20% of oil tea seeds, 10-20% of olives and 5-15% of moringa seeds. The corn and sunflower seed blend oil is subjected to multi-stage separation supercritical CO2 extraction and molecular distillation refinement, wherein the multi-stage separation supercritical CO2 extraction maintains a higher extraction rate and also can simultaneouslyseparate moisture, free fatty acids, odorous components, pigment components and the like due to multi-stage separation; and then by performing refining treatment through a molecular distillation technique, the corn and sunflower seed blend oil with a high oleic acid content and a low acid value is obtained, the oil yield can reach 30% or higher, the acid value is lower than 0.35(KOH)/(mg/g), theunsaturated fatty acid content is 92% or higher and the oleic acid content is 55%-65%. The corn and sunflower seed blend oil disclosed by the invention fills in the gap of lower oleic acid content ofcorn oil and sunflower seed oil, realizes quick refinement of oil and greatly reduces the acid value of the obtained blend oil.
