The modified phospholipids were prepared from soy lecithin and conjugated linoleic acid ethyl ester in a solvent free system.The effects of the kinds of catalysts,the amount of catalyst(based on the mass of lecithin),reaction temperature,reaction time,and mass ratio of lecithin to conjugated linoleic acid ethyl ester on the esterification reaction were investigated.In addition,the product was analyzed by gas chromatography qualitatively and quantitatively.The results showed that the optimum conditions were ... |
