-The objective of this work was to evaluate the tolerance of fruits of different banana cultivars to low temperature storages. Fruits of the cultivars Nanicão (AAA), Prata (AAB), Vitória (AAAB), Maçã (AAB) and Caipira (AAA) were used. Clusters of three fruits were kept in cold storage for 7, 14 and 21 days, with average temperature of 10.53±0.37°C and relative humidity of 85%. Subsequently, the clusters were transferred to temperatures of 22±0.39°C and evaluated for 16 days. The fruits of all cultivars remained green after 21 days of storage at 10.53±0.37°C. Fruits of the cultivar Nanicão did not completely ripened after transferred to the 22°C storage, when stored for 7 days at low temperature. These fruits were firmer, with green peel and low soluble solids and titratable acidity. The fruits of all cultivars complete the ripening when transferred to room temperature after 21 days of cold storage. Chilling injuries increased with cold storage time in all cultivars. The cultivars Nanicão, Caipira and Maçã had more symptoms of chilling injury, while Prata and Vitória were more tolerant to the cold storage (10.53°C) for up to 21 days, showing normal ripening after transferred to the 22±0.39°C storage.Keywords: Musa spp. Chilling injury. Storage. Shelf life. TOLERÂNCIA AO FRIO DE FRUTOS DE DIFERENTES CULTIVARES DE BANANEIRASRESUMO -O objetivo deste trabalho foi avaliar a tolerância dos frutos de diferentes cultivares de bananeira a baixa temperatura de armazenamento. Foram utilizados frutos das bananas Nanicão (AAA), Prata (AAB), Vitória (AAAB), Maçã (AAB) e Caipira (AAA). Utilizaram-se buquês com três frutos, mantidos em câmara fria por 7, 14 e 21 dias, com temperatura média de 10,53±0,37°C e umidade relativa do ar de 85%. Posteriormente, os buquês foram transferidos para a temperatura de 22±0,39°C e avaliados por 16 dias. Os frutos dos cultivares estudados peraneceram verdes após 21 dias de armazenamento a 10,53±0,37°C. Frutos do Nanicão não completaram o amadurecimento após serem transferidos para a temperatura de 22°C, quando armazenados por 7 dias à baixa temperatura, apresentando frutos mais firmes, com casca verde, baixos teores de sólidos solúveis e acidez titulável. Após 21 dias de armazenamento refrigerado, os frutos de todos os cultivares completaram o amadurecimento, depois de transferidos para temperatura ambiente. Os danos por frio aumentaram com o avanço do tempo de armazenamento refrigerado, para todos os cultivares. Nanicão, Caipira e Maçã apresentaram sintomas mais evidentes de dano por frio. As bananas Prata e Vitória mostraram-se mais tolerantes ao armazenamento refrigerado na temperatura de 10,53°C por até 21 dias, exibindo amadurecimento normal após a transferência para a temperatura de 22°C.Palavras-chave: Musa spp. Injúria por frio.

-the northern semiarid region of Minas gerais is an important producer of irrigated Prata-Anã banana variety, which is highly susceptible to fusarium wilt. the organic cultivation of resistant varieties may be an phytosanitary alternative, also adding value to fruits. this study aimed to characterize banana varieties produced in organic system based on chemical and physical assessments at post-harvest. Prata-Anã, BRS Platina, Fhia-18, BRS Conquista and BRS tropical varieties were characterized at the point of harvest (green) and mature (stage six of maturation), by chemical and physical assessments. At the point of harvest, BRS Conquista and BRS tropical banana varieties had more intense green skin color. 'BRS Conquista' presented lower fresh weight, shorter length and diameter than the other varieties. BRS Platinum variety had more fruit fresh mass, length and diameter. Mature Prata-Anã, BRS Platina, Fhia-18, BRS Conquista and BRS tropical banana varieties showed no difference in soluble solids, ph, titrable acidity and ratio; BRS Platina variety had more intense yellow skin color and lower pulp/skin ratio. greater dropping resistance occurred in BRS Conquista variety and BRS tropical was less resistant. Prata-Anã banana variety showed higher firmness. Banana varieties differed more by the physical characteristics (skin color, size, dropping resistance, firmness and pulp/skin ratio) in relation to chemical characteristics. Index Terms: Musa spp., varieties, postharvest. QUALIDADE DE BANANA ORGÂNICA PRODUZIDA NO SEMIÁRIDO DE MINAS GERAISRESUMO -A região norte de Minas gerais, semiárida, é importante produtora de banana 'Prata-Anã' irrigada, cultura altamente suscetível ao mal-do-panamá. O cultivo orgânico de variedades resistentes pode ser uma alternativa fitossanitária, além de agregar valor aos frutos. Objetivou-se caracterizar, em pós-colheita, variedades de banana produzidas em sistema orgânico, com base em avaliações químicas e físicas. As variedades Prata-Anã, BRS Platina, Fhia-18, BRS Conquista e BRS tropical foram caracterizadas no ponto de colheita (verdes) e maduras (estádio seis de maturação), por avaliações químicas e físicas. No ponto de colheita, bananas 'BRS Conquista' e 'BRS tropical' tiveram a cor da casca verde mais intensa. A 'BRS Conquista' apresentou menor massa fresca, menor comprimento e diâmetro do fruto em relação às demais variedades. A 'BRS Platina' produziu frutos com maior massa fresca, comprimento e diâmetro. Bananas 'Prata-Anã', 'BRS Platina', 'Fhia-18', 'BRS Conquista', e 'BRS tropical', maduras, não apresentaram diferença no teor de sólidos solúveis, pH, acidez titulável e ratio; a 'BRS Platina' obteve a casca com tonalidade amarela mais intensa e menor relação polpa/casca. Maior resistência ao despencamento ocorreu em 'BRS Conquista', e a 'BRS Tropical' foi menos resistente. A banana 'Prata-Anã' apresentou maior firmeza. As variedades diferiram mais pelas características físicas (cor da casca, tamanho, resistência ao despencamento, firmeza e relação polpa/casca) em rela...

-In the present work were evaluated the effects of propolis coatings of various botanical sources on quality traits of bananas cv. Prata (Musa sapientum L.) stored at room temperature. ´Prata´ bananas were selected and submitted to five postharvest treatments: four coatings applied by immersion in propolis extracts at a concentration of 2.5% (w/v) and a control (without coating). Propolis extracts were applied as 1) a wild type aqueous propolis extract, 2) a wild type hydroalcoholic propolis extract, 3) a rosemary green type hydroalcoholic propolis extract and 4) a red type hydroalcoholic propolis extract. The bananas were evaluated at three-day intervals along 12 days for fresh weight losses, flesh firmness, soluble solids (SS), titratable acidity (TA), the ratio SS/TA and pH. Sensory analyses were performed after three and six days of storage by 55 not trained panelists designed for acceptability. At the end of the twelve-day storage period, bananas coated either with the rosemary green hydroalcoholic extract or with the aqueous extract presented lower fresh weight losses in comparison to the bananas of the control treatment. No differences were determined in relation to flesh firmness and along the storage period TA values decreased and pH values increased in bananas of all treatments. SS contents increased towards the end of the storage period that, consequently, contributed to increases in the SS/TA ratio. The most significant increase in SS/TA ratio was determined in bananas coated with the red type hydroalcoholic extract. Taste panelists did not detect significant differences amongst coated and not coated cv. Prata bananas up to six days of storage. Index terms: Musa sp., hydroalcoholic extract, taste panel, fruit acceptability, storage. EXTRATO DE PRÓPOLIS NA CONSERVAÇÃO PÓS-COLHEITA DE BANANA 'PRATA'RESUMO -Este trabalho foi realizado com o objetivo de avaliar os efeitos do revestimento com extrato de própolis de diferentes fontes botânicas sobre as características físico-químicas de banana 'Prata' (Musa sapientum L.), armazenada à temperatura ambiente. Bananas 'Prata' foram selecionadas e submetidas à cinco tratamentos pós-colheita, sendo quatro formas de revestimento por imersão em extrato de própolis de diferentes fontes botânicas com concentração de 2,5% (m/v) ("extrato aquoso de própolis do tipo silvestre", "extrato hidroalcoólico de própolis do tipo silvestre", "extrato hidroalcoólico de própolis do tipo verde alecrim e "extrato hidroalcoólico de própolis do tipo vermelho ") e um controle (sem revestimento). As variáveis avaliadas foram perda de massa, firmeza da polpa, sólidos solúveis (SS), acidez titulável (AT), relação entre sólidos solúveis e acidez titulável (SS/AT) e potencial hidrogeniônico (pH), realizadas em intervalos de 3 dias por 12 dias de armazenamento. Realizou-se a análise sensorial das bananas aos 3 e 6 dias de armazenamento, avaliadas por 55 provadores não treinados através do teste de aceitação. Ao final de 12 dias de armazenamento, os revestimentos de extrato de própo...
