The effect of processing of pomegranate juice on antioxidant activity and its relationship with total phenols

The antioxidant activity of pomegranate juices extracted by two methods was determined using three methods: β- carotene, Linoleic acid emulsion, and DiPhenel Picryl Hydrazyl (DPPH). The juice was extracted by separation arils from fruits and squeezed using Cyclone machine (T-1), while the second extraction method included squeezing the whole halve fruit with previous machine, (T-2). The potential compounds were determined using ethanol in a comparison with Butylated hydroxyl Anisole (BHA) as reference antioxidant. There were significant differences (P<0.05) in the antioxidant activity between the treatments in all measuring methods. The means of antioxidant activity amounted to 82.66% in T-1, 86.82% in T-2 and 86.98% in BHA. There was significant relationship between total phenols and antioxidant activity in all treatments.
