Cold pressed marionberry seed oil has been reported to contain antioxidants and possess a remarkable radical scavenging activity and oxygen radical absorption capacity when tested with the DPPH (1,1-diphenyl 1-2-picrylhydrazyl) and ABTS cation radical scavenging assays or the oxygen radical absorption capacity.
The major fatty acids in the cold pressed marionberry seed oil were linoleic, α-linolenic and oleic acids. Linoleic acid comprised approximately 63% of the total fatty acids, whereas α–linolenic acid was present at 16%, suggesting the potential use of marionberry seed oil as a dietary source for essential fatty acids.
Cold-pressed marionberry seed oil also contained a significant level of oxygen radical absorbing agents and exhibited an ORAC (Oxygen Radical Absorbance Capacity) value of 17.2 μmol TE/g oil.
The oxidative stability of oil mainly depends on the fatty acid composition and the presence of antioxidative compounds. Although marionberry seed oils are highly unsaturated oils, their antioxidative stability may be comparable to refined seed oils.
