Resumo: | The objective of this research was to characterize the cocoa (Theobroma cacao L.) pulp traded in Southeast Bahia from the physical, chemical and microbiological standpoints, aiming to improve its quality. The pulp was extracted after different cleaning treatments of the fruit, which did not show any significant influence on the microbiological quality of the pulp. All samples showed low values for total and fecal coliforms; the total plate count determinations reached up to 104 CFU/g and the mold and yeast count was above 3x103CFU/g. The characteristics of the natural cocoa pulp were: soluble solids between 17oand 19o Brix, acidity around 1.5 (0,01 N solution), pH between 3.1 and 3.6, apparent viscosity of 96 cP, at 25°C and deformation rate of 200 s-1. The results were also positive for qualitative determinations of peroxidase and polyphenoloxidase activities. |

A polpa foi extraída após diferentes tratamentos de limpeza dos frutos, os quais pouco influíram na qualidade microbiológica da polpa. Todas as amostras apresentaram baixa contagem de coliformes totais e fecais. Na contagem total em placas foram determinadas até 104 UFC/g, e a contagem de bolores e leveduras também esteve acima de 3x103 UFC/g. A polpa de cacau in natura apresentou teor de sólidos solúveis na faixa de 17o a 19o Brix, acidez em torno de 1,5 (solução 0,01 N) e pH entre 3,1 e 3,6. A viscosidade aparente foi de 96 cP, à temperatura de 25oC, para uma taxa de deformação de 200 s-1. As provas qualitativas de peroxidase e polifenoloxidase apresentaram resultado positivo.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária Brasileiradas Mercês Penha, EdmarMartins da Matta, Virgínia1998-11-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/5003Pesquisa Agropecuaria Brasileira; v.33, n.11, nov. 1998; 1945-1949Pesquisa Agropecuária Brasileira; v.33, n.11, nov. 1998; 1945-19491678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/5003/7173info:eu-repo/semantics/openAccess2014-12-29T18:31:48Zoai:ojs.seer.sct.embrapa.br:article/5003Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-12-29T18:31:48Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
