dc.description.abstractTwo different regional varieties of pears, S. Bartolomeu and Amêndoa, were analyzed fresh and after sun-drying. The total phenolic composition and antioxidant capacity of these pears were determined. The total antioxidant capacity was compared using two different methods: DMPD (N,N-dimethyl-p-phenylenediamine) and the method of ABTS (2,2’-azinobis(3-ethylbenzothiazoline-6-sulfonic acid)) radical scavenging. The ABTS method, when compared with the DMPD method, showed a better correlation between the content of phenolic compounds of the pears and their antioxidant activity. The fresh pear possessed higher amounts of phenolic compounds and higher antioxidant capacity when compared to sun-dried pear. The antioxidant efficiency was expressed as Trolox equivalent and as ascorbic acid equivalent. For both methods, the Trolox equivalent was higher than the ascorbic acid equivalent.por
