“…Firmness analysis and weight loss measurements were conducted to verify the influence of the radiation on the general preservation of the fruit as indicated by water loss and softening. Fante et al (2013), working with apples subjected to different levels of 1-MCP, also noted a decrease in the firmness of fruit during storage due to the action of ethylene regardless of the dose of 1 -MCP.…”

“…Several post-harvest methods have been used to maintain the quality of apples during storage, such as modification of the atmosphere (Fante, Vilas Boas, Paiva, Pires, & Lima, 2014), controlling the atmosphere (Steffens, Giehl, & Brackmann, 2005;Brackmann, Weber, Pinto, Neuwald, & Steffens, 2008), the use of 1-methylcyclopropene (Fante et al, 2013) and the use of different temperatures and concentrations of O 2 and CO 2 (Brackmann, Argenta, & Mazaro, 1996). In addition to these methods, ultraviolet (UV-C) radiation has been recently used to preserve fruits.…”

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 Hue angle, and physicochemical aspects, such as pH, soluble solids, titratable acidity and the soluble solids/titratable acidity ratio. The 4.10 KJ m-2 dose was effective and increased the phenolic content and antioxidant activity for up to 90 days while maintaining the content of vitamin C during storage.

The aim of this study was to evaluate the application of 1-MCP on physicochemical characterization and antioxidant activity of 'Gala' apples mutants, harvested at two different times and maintained in refrigerated atmosphere (0 °C) during 90 days. 'Mondial Gala', 'Imperial Gala' and 'Galaxy' were obtained from commercial orchards. After harvesting, half of the fruits were treated with 1-MCP, and control fruits were maintained in the same condition, but without the treatment. Skin color, pulp firmness, titratable acidity, total soluble solids, total phenolic compounds, anthocyanin and antioxidant activity were evaluated in peel and pulp. The results show that using 1-MCP, pulp firmness was higher than the control. Titratable acidity analysis showed statistical differences for apple clones, harvest point and treatment with 1-MCP. Total soluble solids content was not influenced by the treatments. Epidermis color was statistically influenced by clone (a*, L* and C*), and by harvest point (L*), but 1-MCP did not affect this parameter. The content of total polyphenols and antioxidant activity was higher in the peel when compared to the pulp. 1-MCP proved to be effective in maintaining postharvest quality in all clones and at two harvest points tested.

A vida útil pós-colheita do taperebá é muito curta mesmo em condições de refrigeração, assim o presente trabalho tem por objetivo avaliar a influência de diferentes concentrações de 1–metilciclopropeno (MCP) sobre a conservação e preservação da qualidade deste fruto visando maior tempo de comercialização na forma in natura. Adotou-se um delineamento experimental inteiramente casualizado em arranjo fatorial 4x5 com cinco repetições. A cada três dias os frutos de cada tratamento foram avaliados quanto à perda de massa fresca, firmeza da polpa, pH, o conteúdo de sólidos solúveis, teor de vitamina C, acidez titulável, índice de maturação e taxa respiratória. Os resultados demonstraram efeito significativo em todas as características avaliadas tanto no tempo de armazenamento quanto entre os tratamentos. De modo geral, o 1–MCP controlou as alterações fisiológicas nos frutos principalmente sobre os atributos quantitativos de sólidos solúveis, firmeza da polpa, acidez e teor de vitamina C, pH e perda de massa fresca. Concentrações entre 100 e 150 mg L-1 de 1-MCP são recomendadas para a pós-colheita do taperebá por promover maior conservação durante o armazenamento refrigerado dos frutos.
