| Abstract: | "The effect of dihydrosphingosine (d18:0) on triacylglycerol (TAG) oxidation was examined with and without alpha-tocopherol. Three types of TAG from fish, linseed, and soybean oil were oxidized at 50 degrees C to determine the effect of dihydrosphingosine (d18:0) with or without alpha-tocopherol on triacylglycerol (TAG) oxidation. The analysis of oxygen consumption and total volatile formation demonstrated a small effect of d18:0 on TAG oxidation in the absence of alpha-tocopherol. On the other hand, the combination of d18:0 with alpha-tocopherol showed strong antioxidant activity and completely inhibited volatile formation within 1400 h for soybean oil TAG, 650 h for linseed oil TAG, and 380 h for fish oil TAG" |
