DPPH free radical-scavenging capacity
The results showed that HHPE led to the highest antioxidant
capacity, followed by UAE and CE. The antioxidant capacity values
of Chilean papaya seeds increased significantly (p 0.05) with
different extraction methods, from 9.3%, 40.4% and 66.8% for UAE at
5 min, 10 min and 15 min, respectively, to 129.3%, 242.7% and
272.8% for HHPE at 500 MPa for 5 min, 10 min and 15 min,
respectively, when compared to conventional extraction (see
Fig. 1). Therefore, papaya seeds are another by-product of a fruit
