Summary
The ultraviolet spectral changes produced in soybean oil by treatment with heat and visible and ultraviolet light have been determined. Heat treatment appears to cause more deep-seated changes than does exposure to visible or ultraviolet irradiation. Distinct flavor changes occur in soybean oil under these different conditions; that produced by visible light of strong intensity being the easiest to recognize.
A preliminary study is reported on the methods used to concentrate and isolate the substances responsible for the off-flavor of heat-treated soybean oil.
