| This work aimed to evaluate the physicochemical characteristics and enzymatic activity of “Sabará” jabuticaba fruits, which were cultivated in Lavras, Minas Gerais State, Brazil, at different maturation stages. The fruits were harvested and separated into five different stages: totally green fruit, fruit with incipient pigmentation, fruit with a light purple predominance, totally purple fruit and totally dark purple fruit. These fruits were physicochemically analyzed and evaluated for polygalacturonase enzymatic activity. Chlorophyll degradation and the synthesis of anthocyanin on fruit rinds were observed, as well as the degradation of the cell wall and its consequent softening. In the pulp, increased soluble solids, pH and sugars were observed, while... |

| UV-C radiation is a food preservation method aimed to extend the life of the product, inactivate microorganisms, and stimulate the synthesis of phenolic compounds. This study aimed to physicochemically characterize and evaluate the antioxidant activity and phenolic content of ‘Gala’ apples subjected to different UV-C radiation doses.The fruits were harvested, sanitized, selected and inserted into a UV-C radiation chamber, and different radiation doses were applied as follows:0 KJ m-2 (0 min.), 0.68 KJ m-2 (2 minutes),2.73 KJ m-2 (4 minutes), and 4.10 KJ m-2 (6 minutes). The apples were stored for 120 days at 5 ± 1°C and analyzed after 0, 30, 60, 90, and 120 days of storage. Radiation doses had no influence on parameters, such as weight loss, firmness and... |
