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.

ABSTRACT: The objective of this research was to evaluate the nutritional composition and bioactive compounds of whole umbu fruit, including pulp, seed and peel, and also of a commercial umbu pulp. Samples of the fractions and of commercial pulp were analyzed for determination of minerals and proximate composition, total phenolic and antioxidant activity. Pulps and peel were also analyzed for vitamin C and carotenoids contents. Commercial pulp presented better nutritional composition than fresh pulp (P<0.05) and the peel presented higher phenolic content and antioxidant activity than seed. Peel also stood out by its vitamin C (79 mg.100 g-1) and total carotenoids (2,751 µg.100 g-1) contents, showing that, as the main barrier of the fruit for its protection, it is a fraction rich in bioactive compounds. The highest dietary fiber and iron contents were observed in umbu seed (P<0.05). Therefore, umbu by-products may be ingredients proper for development of food richer in nutrients and bioactive compounds.

In the present study, valorization of yarrow (Achillea millefolium) by-product from the filter tea industry was investigated through the application of subcritical water for the extraction of bioactive compounds. The influence of different process parameters (temperature 120–200 °C, extraction time 10–30 min, and HCl concentration in extraction solvent 0–1.5%) on extract quality in terms of content of bioactive compounds and antioxidant activity was investigated. Optimal conditions of the extraction process (temperature 198 °C, extraction time 16.5 min, and without acidifer) were determined and, when applied, the most efficient exploitation of by-products is achieved, that is, attainment of extracts rich in total phenols and flavonoids and high antioxidant activity. In addition, by applying the high performance liquid chromatographic analysis, the content of chlorogenic acid was determined as well as the hydroxymethylfurfural content in obtained extracts. The results demonstrated that subcritical water can be successfully used for utilization of yarrow by-products for obtaining extracts rich in antioxidants.
