Lipid oxidation was studied in rapeseed oil, stored at 35 or 50 degrees C i
n 0.03, 0.3, 1.0 or 1.8% oxygen for 42 days. Peroxide value (PV), oxygen co
nsumption, tocopherol consumption end production of volatile compounds were
analyzed to follow the oxidation, At 50 degrees C, lipid oxidation measure
d as oxygen consumption or PV was only slightly influenced by oxygen concen
tration greater than or equal to 1%. Below 0.5% the influence was strongly
enhanced. The production of volatiles showed different relationships to oxy
gen concentration and some compounds were produced in larger amounts at low
er O-2, than at higher O-2 concentrations.
