Description

一种用于超临界CO2萃取枸杞籽油前的纯植物改性剂A kind of pure plant modifier before supercritical CO2 extraction of Lycium barbarum seed oil

技术领域 technical field

本发明涉及一种萃取工艺。 The invention relates to an extraction process.

背景技术 Background technique

枸杞籽即枸杞的种子,含有孕育生命发育和生长的丰富而全面的生物活性物质。而枸杞籽油正是以枸杞籽为原料,利用现代化萃取技术提取的,有效的保留了枸杞的多种功能成分如:亚油酸、γ-亚麻酸、VE、β-胡萝卜素、生物碱等的保健品,其中人体必需脂肪酸含量高达80%以上,不饱和脂肪酸总含量达99%,β-胡罗卜素、维生素E、有机硒、隐黄质等含量极高。 Lycium barbarum seeds, the seeds of wolfberry, contain rich and comprehensive biologically active substances that nurture life development and growth. Lycium barbarum seed oil is extracted from wolfberry seeds using modern extraction technology, effectively retaining various functional components of wolfberry such as: linoleic acid, γ-linolenic acid, VE, β-carotene, alkaloids, etc. Health care products, in which the content of essential fatty acids is as high as 80%, the total content of unsaturated fatty acids is 99%, and the content of β-carotene, vitamin E, organic selenium and cryptoxanthin is extremely high.

枸杞籽油可降低人体血浆胆固醇含量,防止血脂及动脉粥样硬化症;对高血脂所引起的高血压、冠心病有显著的缓解作用;直接参与皮肤新陈代谢,消除氧自由基,延缓皮肤衰老,加强皮肤水合功能,使皮肤柔软并富有弹性,有明显增白效果;此外,食用枸杞籽油还可以消除人体皮肤中的褐色斑、黑色素,令皮肤更有光泽,可抑制青春痘、痤疮、暗疮的再生,能缓解体力疲劳,有效改善睡眠等功效。因此,充分开发利用枸杞籽油源,对于改善我国人民的膳食结构,提高人民的生活水平有着重大的意义。 Lycium barbarum seed oil can reduce human plasma cholesterol content, prevent blood lipids and atherosclerosis; it has a significant alleviating effect on hypertension and coronary heart disease caused by hyperlipidemia; it directly participates in skin metabolism, eliminates oxygen free radicals, and delays skin aging. Strengthen the hydration function of the skin, make the skin soft and elastic, and have obvious whitening effect; in addition, eating wolfberry seed oil can also eliminate brown spots and melanin in the human skin, make the skin more shiny, and inhibit acne, acne, and acne Regeneration, can relieve physical fatigue, effectively improve sleep and other effects. Therefore, the full development and utilization of wolfberry seed oil source has great significance for improving the dietary structure of our people and improving people's living standards.

超临界CO2流体萃取(SFE)是利用超临界流体的溶解能力与其密度的关系,即利用压力和温度对超临界流体溶解能力的影响而进行的。在超临界状态下,将超临界流体与待分离的物质接触,使其有选择性地把极性大小、沸点高低和分子量大小的成分依次萃取出来。在枸杞籽油的萃取工艺中,现代更回倾向超临界CO2萃取枸杞籽油。然而,由于枸杞籽的拥有很坚固的细胞壁,所以严重影响了萃取的效率,而现有的枸杞籽结构改性剂即使能够提高萃取率,也会给后期的除溶剂带来很大的麻烦,影响油脂的品质。 Supercritical CO2 fluid extraction (SFE) is carried out by using the relationship between the dissolving power of supercritical fluid and its density, that is, using the influence of pressure and temperature on the dissolving power of supercritical fluid. In the supercritical state, the supercritical fluid is contacted with the substance to be separated, so that it selectively extracts the components of polarity, boiling point and molecular weight in sequence. In the extraction process of wolfberry seed oil, modern times are more inclined to supercritical CO 2 extraction of wolfberry seed oil. However, due to the strong cell wall of wolfberry seeds, the extraction efficiency is seriously affected, and even if the existing structure modifiers of wolfberry seeds can improve the extraction rate, it will bring great trouble to the solvent removal in the later stage. affect the quality of the oil.
