Omega-7脂肪酸的功能研究现状
Omega-7脂肪酸是一组单不饱和脂肪酸。近年来, 随着相关研究的深入, 其营养价值和生理功能越来越为人们所认识。如可作为信号分子在机体代谢中发挥重要作用, 可提高人体对胰岛素的敏感性, 对糖尿病、代谢综合征和动脉粥样硬化有一定功效, 有助于抵抗炎症和控制体重等。目前国外已有?-7脂肪酸相关保健食品上市, 但由于其在体内的代谢研究尚未完善等原因, 国内进行相关保健食品的生产研究较少。天然?-7脂肪酸常见于秘鲁凤尾鱼、野生鲑鱼等深海鱼类和沙棘果油、澳洲坚果油、海藻等植物类食品中, 但其含量很低。高浓度的?-7脂肪酸需要通过特殊纯化工艺提取, 目前采用的方法一般是分子蒸馏和超临界CO2萃取。本文综述?-7脂肪酸在食品、保健品方面的功能研究现状及产品开发情况, 旨在为?-7脂肪酸的开发利用提供参考。
Omega-7 fatty acids are a group of monounsaturated fatty acids. In recent years, with the deepening of related researches, their nutritional values and physiological functions are more and more recognized. For example, as signal molecules, ?-7 fatty acids play an important role in improving the body's sensitivity to insulin and have a certain effect on diabetes, metabolic syndrome and atherosclerosis. They can also help to resist inflammations and control body weight. Some ?-7 fatty acid health food are already for sale abroad. Due to the in vivo metabolic mechanism of ?-7 fatty acids is not clear and other reasons, domestic research about the production of related health food is relatively less. Natural ?-7 fatty acids are common in Peruvian anchovies, wild salmons and other deep-sea fishes, as well as plants like seabuckthorn oil, macadamia oil, seaweed and others, with very low content. High concentrations of ?-7 fatty acids require special purification after extraction, such as molecular distillation and supercritical CO2 extraction, and so on. In this paper, the function and development of Omega-7 fatty acids in food and health products were reviewed, so as to provide references for the development and utilization of Omega-7 fatty acids.
