ABSTRACT: The aim of this study was to characterize five different hybrid cultivars pears (‘Tenra’, ‘Centenária’, ‘Cascatence’, ‘Primorosa’ and ‘Seleta’) deployed in subtropical regions of Brazil regarding its physicochemical characteristics, bioactive compounds and antioxidant activity, as well as to evaluate the influence of these cultivars on the characteristics physicochemical, rheological properties and sensory acceptance of the obtained jelly, for identifying varieties with higher potential for industrial use. Regardingthe bioactive compounds and antioxidant activity it was observed that ‘Seleta’ cultivar was characterized by a higher phenolic content (57.68mg GAEs 100g-1), higher antioxidant activity (13.56% of DPPH sequestration and 1.25µM of trolox g -1) and higher content of vitamin C (3.59mg 100g-1). As the acidity, it ranged from 4.09 to 5.81 g of malic acid 100g-1 (‘Tenra’ and ‘Seleta’, respectively). Regarding color, the color parameter L* varied from 32.14 to 36.83, a* ranged from 2.87 to 5.20, b* ranged from 16.57 to 20.42, Chroma ranged from 16.67 to 21.02 and °Hue ranged from 74.94 to 80.18. Regarding the texture, the jellies produced from ‘Centenária’ and ‘Tenra’ were characterized by having the highest values of hardness (1.21 and 1.23N, respectively), gumminess (0.42 and 0.45, respectively) and chewiness (0.40 and 0.45N, respectively). The jelly obtained from the ‘Centenária’ still showed the highest adhesiveness (2.27N s-1) and springiness (0.99). Already jellies prepared by ‘Cascatence’ showed the highest cohesiveness values (0.68). The jellies prepared with different pear cultivars showed good sensory acceptance for all measured properties, with average scores ranging between the hedonic terms “liked slightly” to “liked very much”. Cultivars of subtropical pear trees present different physicochemical characteristics, resulting in jellies with different physicochemical characteristics and rheological properties. Processing in the form of jelly is extremely viable due to the good acceptance by consumers of all formulations elaborated.
