There was a close relationship (r = 0.92} between the tocored content in crude oil and the Rm value that the soybean salad oil reached during color reversion. As shown in Figure 5, the tocored content of soybean oil changed in different refining steps, especially in the process of neutralization.

Therefore, the c o n t e n t s of y-tocopherol or y-TED in crude soybean oil could be used as an index for predicting the color quality Icolor reversion} of soybean salad oil. A l m o s t all the precursors {such as tocored} were converted to color-reverted s u b s t a n c e s under catalysis after bleaching treatment, and they were converted back to the precursors during deodorization.

Refining of Soybean Oil - Project Topics

Crude soybean oil of good quality has a lighter amber colour which upon alkali refining is reduced to the light yellow colour of most vegetable seed oils. Soybean oil produced from green or immature beans may contain sufficient chlorophyll to have a greenish cast but this is not usually very evident until after the yellow red pigment of the oil ...
