Description
Summary:ABSTRACT This study aimed to evaluate the physico-chemical composition of native fruits of the Ceará coast at different development stages. The fruits of ‘guajiru’, ‘manipuçá’, ‘murici-pitanga’ and ‘murta’ were collected during the year 2014, and the following evaluations were made: total soluble solids, total titratable acidity, pH, total soluble solids and titratable acidity ratio. A completely randomized design was used, with 5 or 6 treatments, depending on the maturation stage and 4 replicates. For total soluble solids, ‘murta’ obtained a minimum of 2.6 °Brix in stage 1 and ‘manipuçá’ obtained maximum of 24.53 °Brix in stage 5. For the total titratable acidity, ‘guajiru’ showed minimum of 0.09% in stages 3 and 4, and ‘murici-pitanga’ showed maximum of 3.29% in stage 6. ‘Murici-pitanga’ had minimum pH of 3.44 in stage 5 and ‘guajiru’, maximum pH of 5.9 in stage 2. For total soluble solids and titratable acidity ratio, ‘murici-pitanga’ exhibited a minimum of 3.25 in stages 1 and 3, and ‘guajiru’ showed maximum of 141.11 in stage 4. It was concluded that ‘guajiru’ and ‘manipuçá’ fruits reached physiological maturity in stage 3, whereas ‘murici-pitanga’ and ‘murta’ fruits reached in stage 4; thus, these are the ideal stages for fruit harvest. RESUMO Objetivou-se, com este trabalho, avaliar a composição físico-química de frutas nativas do litoral cearense em diferentes estádios de desenvolvimento. Os frutos de guajiru, manipuçá, murici-pitanga e murta, foram colhidos durante o ano de 2014, através das seguintes avaliações: sólidos solúveis totais, acidez total titulável, pH e relação sólidos solúveis totais e acidez total titulável. Utilizou-se o delineamento inteiramente casualizado com 5 ou 6 tratamentos, dependendo do estádio de maturação do fruto e 4 repetições. Para sólidos solúveis totais a murta obteve mínimo de 2,6 ºBrix no estádio 1 e o manipuçá obteve máximo de 24,53 ºBrix no estádio 5. Na acidez total titulável, o guajiru com mínimo de 0,09% nos estádios 3 e 4, e o murici-pitanga com máximo de 3,29% no estádio 6. Para o pH no murici-pitanga foi obtido mínimo de 3,44 no estádio 5 e o guajiru, máximo de 5,9 no estádio 2. Para a relação sólidos solúveis totais e acidez total titulável, o murici-pitanga com mínimo de 3,25 nos estádios 1 e 3 e o guajiru com máximo de 141,11 no estádio 4. Concluiu-se que os frutos do guajiru e do manipuçá atingiram a maturidade fisiológica no estádio 3; já os frutos do murici-pitanga e da murta os atingiram no estádio
