摘要
油脂改性主要包括分提、氢化及酯交换3种方法。主要对这3种油脂改性技术的起源、分类、各自的优劣性以及目前的应用及研究现状进行了介绍,同时指出这3种改性技术存在的问题,并对其未来发展进行了展望。干法分提是物理改性过程,生产中无反式脂肪酸生成、无催化剂污染,因而其应用前景广阔;油脂氢化过程存在反式脂肪酸问题,今后应重点开发具有高活性、低反式脂肪酸、低消耗的催化剂体系;酶法酯交换具有高效、专一,反应条件温和,副产物少,污染少,将是今后油脂改性的重要方法。
Oils and fats modification technology includes fractionation, hydrogenation and transesterification. The origin, classification, advantages and disadvantages, application and research status＇of the three kinds of modification technology were introduced, the problems of these three kinds of modification technology were also pointed out, and the future development was prospected. The dry fractionation was a physical modification process, and there was no trans fatty acids and no catalyst contamination, therefore it had wide application prospect. For the exist of trans fatty acids in the hydrogenation process, the development of high activity, low trans fatty acids and low consumption of catalyst system would be focused on in the future. Transesterification catalyzed by enzyme would be an important methods because of high efficiency, moderate conditions,little by - products and contamination.
