DHA油脂在精炼过程中氧化稳定性的变化
Oxidative stability of DHA oil during the refining process
摘要
Abstract
The composition and oxidative stability of DHA oil was investigated during the refining process (deguming, alkali refining, bleaching and deodorization). It was found that all of minor compounds decreased during the whole process.The order of oxidative stability of DHA oil against light was deodorized > bleached > crude/degummed > alkali refined oil.The order of oxidative stability of DHA oil against heat( Rancimat method) was bleached > deodorized > degummed > crude > alkali refined oil.The oxidative stability of DHA oils before bleaching step was poor because of too many prooxidants in oils,and the deodorized oil was less stable against heat due to the loss of antioxidants in the deodorization.关键词
