Resumo: The study was undertaken to increase the shelf life of fruits of guava (Psidium guajava L.) var. Paluma in the post-harvest period in the São Francisco River Valley (Petrolina, PE, Brazil). Effects of calcium (Ca) concentration, storing condition and fruit wrapping material in the shelf life of fruit of guava were studied. Twelve treatments were tested in a randomized complete block design, in a 2 x 3 x 2 factorial arrangement, comprising the following variables: two storing conditions (natural temperature and refrigerated), three Ca concentrations (0.5, 1.0 and 1.5%) and two fruit wrapping materials (transparent poliethylene bag and impervious paper bag). The following guava parameters were evaluated: weight and peel green color losses and total soluble solids. It was observed that when the fruit was harvested just before ripening (fruit reaching complete growth but still with green peel) it maintained its commercial characteristics for up to sixteen days when wrapped in transparent poliethylene bag and stored under refrigeration at 10°C and 90% of relative humidity.

Foram estudados dois ambientes de armazenamento (condições naturais e ambiente refrigerado), três concentrações de Ca (0,5, 1,0 e 1,5%) e dois tipos de embalagem do fruto (saco de polietileno transparente e saco de papel-manteiga). Doze tratamentos foram testados no delineamento de blocos ao acaso, com três repetições, num arranjo fatorial 3x2x2. Foram determinados os parâmetros: perda de peso e da cor verde da casca do fruto, e o teor de sólidos solúveis totais. Verificou-se que frutos da variedade Paluma colhidos "de vez" (frutos completamente desenvolvidos, mas com a casca verde) mantiveram suas características comerciais por até dezesseis dias de armazenamento quando foram embalados em saco de polietileno transparente e sem furo, e armazenado em ambiente refrigerado a 10oC, e 90% de umidade relativa.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraNeto, Luiz GonzagaCristo, Amenaide SilvaChoudhury, Mohammad Menhazuddin1999-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/5140Pesquisa Agropecuaria Brasileira; v.34, n.1, jan. 1999; 1-6Pesquisa Agropecuária Brasileira; v.34, n.1, jan. 1999; 1-61678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/5140/2332info:eu-repo/semantics/openAccess2010-07-14T13:12:04Zoai:ojs.seer.sct.embrapa.br:article/5140Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-07-14T13:12:04Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
