暨南大学硕士学位 暨南大学硕士学位论文 PAGE PAGE VI MAGs shifted to higher temperatures. These data indicated that using hydrogenation to change the fatty acid composition could effectively increase the oxidation stability of MAGs. (5) Two-stage molecular distillation was introduced to purify the produced MAGs. The unreacted glycerol and free fatty acid in the glycerides were removed at an evaporator temperature of 140 ℃ at the first stage. MAGs with a purity of above 90.0 % were obtained at an evaporator temperature of 190 ℃ at the second stage.
