Abstract

A study of crude soy oils by ultraviolet spectrophotometry showed E 1%1cm values at 233 nm ranging from 1.6 to 2.0. These E 1%1cm values can be used as a measure of the conjugated diene compounds of soy oil. E 1%1cm values for purified triglycerides were 0.78 (tristearin), 1.1 (triolein), and 0.71 (trilinolein). For the triglyceride fraction of crude soy oil after separation by high performance liquid chromatography (HPLC) the E 1%1cm was 0.98. HPLC separation of components in crude soy oil led to a tentative identification of a triglyceride fraction, a carotene fraction, 2 tocopherol fractions, and 4 conjugated diene fractions.
