超长碳链脂肪酸在专用油脂中应用的研究进展

超长碳链脂肪酸(VLCFAs),特别是饱和及部分单不饱和超长碳链脂肪酸在工业和医学领域有广泛的应用,并因其具有独特的消化代谢途径和功能特性,近年来在食品工业中也显示出了相当大的应用潜力,引起了企业和研究者的广泛关注。介绍了常见VLCFAs（山嵛酸、芥酸、木蜡酸、神经酸）的来源和特点,阐述了VLCFAs对甘油三酯体系结晶的影响,并对其作为抗霜剂及促晶剂、低热量基料油、强化型基料油在人造奶油、起酥油、代可可脂等专用油脂中的应用现状进行了综述,提出了应用中存在的问题,并对未来的发展趋势进行了展望。

Advance in application of very long chain fatty acids in specialty oils and fats

Very long chain fatty acids(VLCFAs), especially saturated and monounsaturated VLCFAs, have been widely used in the industrial and medical fields, while they have also shown considerable application potentials in the food industry in recent years because of their unique digestive and metabolic pathways and function characteristics. The sources and characteristics of common VLCFAs (behenic acid, erucic acid, lignoceric acid and nervonic acid) were introduced, and their effects on crystallization of triglyceride systems were also described. Their application and research status for the production of shortening, margarine and cocoa butter replacers as anti-frost agent and crystal promoter, low calorie base oil, strengthening base oil were summarized, and their development trends were also discussed.
