脂质伴随物对多不饱和脂肪酸乳液稳定性的影响研究进展

α-亚麻酸、二十二碳六烯酸、二十碳五烯酸以及n-6 PUFA亚油酸等多不饱和脂肪酸（PUFA）对人体具有显著的健康功效，目前被广泛应用于在食品、医药等领域。但是含有PUFA的油脂极易被氧化，且具有强疏水性，因此其应用受到一定限制。乳液递送体系是一种经典的脂质载体，现已被应用于高生物利用率的PUFA产品的研究与开发中。脂质伴随物是来源于油脂的天然植物化合物，主要包括多酚、植物甾醇、磷脂、脂溶性维生素等。研究表明，将一定量的脂质伴随物添加入乳液体系中能够有效改善体系的稳定性。基于此，本文主要归纳总结了极性多酚类化合物、双亲性植物甾醇及磷脂、非极性维生素等脂质伴随物对乳液稳定性的影响及潜在的作用机制，并针对研究中存在的科学问题以及发展方向进行了分析和展望。

Review of lipid concomitants effects on stability of polyunsaturated fatty acid emulsion #br#

For pronounced functional efficiency for human, α -linolenic acid (ALA), docosahexaenoic acid (DHA), eicosapentaenoic acid (EPA) and n-6 PUFAs linoleic acid have been widely applied in foods and drugs. But their applications are limited owing to oxidation and strong hydrophobicity nature. Thus the lipid carriers as emul? sion delivery system has been used to develop PUFA productions with highly bioavailability. Lipid concomitant is natural phytochemical extracted from oilseeds or oil, including polyphenols, phytosterols, phospholipids, fat-soluble vitamins, etc. A number of publications reported the stability of O/W (oil in water) emulsion system affected by lipid concomitant. In this paper, we reviewed recent advances of the effects of hydrophilic polyphenols, amphiphilic phy? tosterols and phospholipids, lipophilic vitamins on emulsion stability and on their potential mechanism. We also dis? cussed scientific problems on research and potential application of lipid concomitant.
