However, its commercialization comes up against the short post-harvest life of these fruits, which need to be consumed as soon as possible after their harvest, otherwise their fermentation process begins and they end up becoming unfit for consumption. For this problem, the present study aimed to prolong the postharvest conservation time of jaboticabas, in good consumption conditions for at least 10 days, with the use of modified atmosphere. The study was carried out with fresh jaboticabas, fruits of uniform size and color were selected, free from mechanical injuries or caused by insects. The fruits were packed in expanded polystyrene trays and covered with 9 and 17 micron PVC film, with or without potassium permanganate sachet. A control was also added without any treatments (PVC film and / or potassium permanganate). All treatments were stored in a B.O.D. at a temperature of 10 ° C for 10 days. At the end of this period, all trays were removed and mass loss, soluble solids content, titratable acidity, texture, pH, color and tasting were analyzed. From the data collected, it was found that the use of the modified atmosphere with plastic film and potassium permanganate enabled greater conservation of the jaboticabas, in comparison with the additional control (fruits kept only under 10 ° C refrigeration). There was a delay in senescence, with a lower concentration of Soluble Solids (SS) and Titratable Acidity (AT), when the modified atmosphere treatments were used, in addition to greater maintenance of the firmness of the fruit and the original color, especially when the PVC treatments were combined. thicker (17 μm) and the use of potassium permanganate, since more than half of the fruits were suitable for consumption (average of 58%). In the control, no fruit was suitable for consumption, due to external wilting and pulp fermentation, after 10 days of storage at 10 ° C. A jaboticabeira é uma árvore que produz seus frutos em abundância a cada frutificação e os mesmos são muito apreciados pela maioria das pessoas, seja ele consumido in natura, ou através de doces e geleias. Porém sua comercialização esbarra na curta vida pós-colheita desses frutos, que precisam ser consumidos o mais brevemente possível após sua colheita, caso contrário se dá início o seu processo de fermentação e eles acabam se tornando impróprios para o consumo. Para tal problemática o presente estudo objetivou-se prolongar o tempo de conservação pós-colheita de jaboticabas, em boas condições de consumo por ao menos 10 dias, com o uso de atmosfera modificada. O estudo foi realizado com jaboticabas frescas, foram selecionados frutos de tamanho e coloração uniforme, livres de injúrias mecânicas ou causadas por insetos. Os frutos foram acondicionados em bandejas de poliestireno expandido e revestidas com filme de PVC de 9 e 17 micras, com ou sem sachê de permanganato de potássio. Foi adicionado também uma testemunha sem quaisquer tratamentos (filme PVC e/ou Permanganato de potássio). Todos os tratamentos foram armazenados em câmara tipo B.O.D. a uma temperatura de 10 °C durante 10 dias. Ao final desse período, todas as bandejas foram retiradas e realizou-se análises de perda de massa, teor de sólidos solúveis, acidez titulável, textura, pH, cor e degustação. A partir dos dados coletados ficou constatado que o uso da atmosfera modificada com filme plástico e permanganato de potássio possibilitou maior conservação das jaboticabas, em comparação com a testemunha adicional (frutos mantidos apenas sob refrigeração de 10 °C). Houve retardamento da senescência, com menor concentração de Sólidos Solúveis (SS) e Acidez Titulável (AT), quando utilizados os tratamentos de atmosfera modificada, além de maior manutenção da firmeza do fruto e da coloração original, principalmente quando foram combinados os tratamentos de PVC de maior espessura (17 μm) e o uso do permanganato de potássio, pois mais da metade dos frutos estavam aptos ao consumo (média de 58%). Na testemunha nenhum fruto estava apto ao consumo, devido ao murchamento externo e fermentação da polpa, após 10 dias de armazenamento à 10 °C. 2022-02-22T12:30:23Z 2022-02-22T12:30:23Z 2021-04-22 bachelorThesis PAGNONCELLI JUNIOR, Francisco.

The jaboticaba tree is a tree that produces its fruits in abundance with each fruiting and they are very appreciated by most people, whether consumed in natura, or through sweets and jellies. However, its commercialization comes up against the short post-harvest life of these fruits, which need to be consumed as soon as possible after their harvest, otherwise their fermentation process begins and they end up becoming unfit for consumption. For this problem, the present study aimed to prolong the postharvest conservation time of jaboticabas, in good consumption conditions for at least 10 days, with the use of modified atmosphere.
