折光

Result and Conclusion: The yolk oils processed by daking and dry distillation are almost similar in the contents of fatty oils, type of fatty acids, acid value, iodine value, saponification value, relative density and refractive index, while obvious differences were found in the products processed by chloroform extraction.

结果 ：烘法和干馏法炮制的蛋黄油中脂肪油含量，所含脂肪酸的种类、含量以及酸值、碘值、皂化值、相对密度、折光率相近，氯仿提取法制备品则差异较大。结论：烘法和干馏法制备的蛋黄油中脂肪油部分没有明显区别，二者与直接用氯仿提取的蛋黄脂肪油相比则有较大差异。
