| Abstract | ||
| The effect of 6 solvents with different polarities on the extraction of pomegranate seed extracts was studied. Extraction efficiency, reducing activity, radical scavenging properties and the effect of each extract on thermal resistance (oxidative stability index) of antioxidant-free soybean oil were analyzed using a factorial test in a completely randomized design with 3 replications. The results showed that the highest extraction yield from pomegranate seeds was hexane extract and from defatted seeds was acetone extract. The antioxidant properties of the different extracts were analyzed using FRAP and DPPH and revealed that methanol seed extract had the highest antioxidant properties. The antioxidant efficiency of the seed extracts prepared using solvents in combination with antioxidant-free soybean oil was measured using a Rancimat. The results showed that methanol seed extract increased the oxidative stability of the oil sample. | ||
