Resumo: | The objective of this work was to determine the harvest point and to characterize the postharvest of camu‑camu (Myrciaria dubia) fruit harvested at different maturity stages. The fruits are harvested at four maturity stages, defined by skin color: green, reddish‑green, red‑greenish, and purple. Fruit were cold‑stored at 22±1°C and 85±5% RH. It was used a completely randomized design, split‑potted in time, with five storage periods: 0, 3, 6, 9, and 12 days. Evaluations were made for: respiratory activity; ethylene production; skin color, determined with the hue angle and chromaticity coordinates a* and b*; firmness; fresh matter weight loss; contents of chlorophyll, anthocyanins, soluble solids, and ascorbic acid; titratable acidity; and rot incidence. Peaks of CO2 and ethylene production occurred after harvest. The contents of chlorophyll and anthocyanins varied according to the changes in skin color, from green to purple, which confirmed fruit ripening. The contents of ascorbic acid ranged from 759.02 mg per 100 g, in the green stage, to 1,071.12 mg per 100 g, in the purple one. Fruit harvested with complete purpled skin had reduced postharvest life. Best postharvest quality for camu‑camu is achieved when skin color is red‑green. |

A colheita dos frutos foi realizada em quatro estádios de maturação, definidos pela cor da casca: verde, verde‑avermelhada, vermelho‑esverdeada e roxa. O armazenamento foi feito em câmaras de refrigeração a 22±1°C e 85±5% UR. Utilizou-se delineamento experimental inteiramente casualizado, em parcelas subdivididas no tempo, com cinco períodos de armazenamento: 0, 3, 6, 9 e 12 dias. Foram avaliados: atividade respiratória; produção de etileno; coloração da casca verificada pelo ângulo de cor e coordenadas de cromaticidade a* e b*; firmeza; perda de massa de matéria fresca; teores de clorofilas, antocianinas, sólidos solúveis e ácido ascórbico; acidez titulável; e incidência de podridão. Os picos de produção de CO2 e etileno ocorreram após a colheita. Os teores de clorofilas e antocianinas variaram com a mudança na coloração da casca de verde para roxa, o que confirmou a maturação dos frutos. Os teores de ácido ascórbico variaram de 759,02 mg por 100 g, no estádio verde, a 1.071,12 mg por 100 g, no roxo. Os frutos colhidos totalmente roxos têm reduzida vida pós‑colheita. A maior qualidade pós‑colheita do camu‑camu é obtida quando os frutos são colhidos com coloração vermelho‑esverdeada.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFAPESP (Fundação de Amparo à Pesquisa do Estado de São Paulo)Pinto, Patrícia MariaJacomino, Angelo PedroSilva, Simone Rodrigues daAndrade, Carolina Amanda Wippich2013-09-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/14236Pesquisa Agropecuaria Brasileira; v.48, n.6, jun. 2013; 605-612Pesquisa Agropecuária Brasileira; v.48, n.6, jun. 2013; 605-6121678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/14236/12151https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/14236/9579info:eu-repo/semantics/openAccess2013-09-05T19:39:27Zoai:ojs.seer.sct.embrapa.br:article/14236Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2013-09-05T19:39:27Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
