The distribution of unsaturated and saturated fatty acid determines the hardness, aroma, cleansing, lather, and moisturizing abilities of soaps. It was relatively easy to make the optical data free of bias by observations of predetermined sections of the microscope slides. 1. A comprehensive literature search on egg cholesterol content showed that there is a wide range of results, primarily because of the breed of laying hens and production practices [], but also could be due to the method of cholesterol quantification.The standard method for quantification of cholesterol is saponification (AOCS method Ca 6b-53) followed by GC.
