Previous issue date: 2006-02-21 / The present study was released at the UFRRJ, having the objectives to analyze the age influence on the dwarf-green coconut s constituent in fruits originated from inflorescences emitted at the winter time, in the Baixada de Sepetiba area, and to determine the ideal harvest point for the liquid albumen consumption of in natura fruits. Initially, the inflorescences were marked, and experimental samples were taken from the 4th month until the 12th month after the inflorescence emission. After that, fruits in the CEASA-RJ had been acquired, proceeding from different producing regions (Linhares/ES, Rio Bananal/ES, Itagua?/RJ and Santa Cruz/RJ) and compared with fruits harvested in the 6th and 7th months in the previous experiment. The external measures (Length, Width and Length/Width Relation) and interns ones (Length and Width of the internal socket; and Length/Width Relation of the internal socket) had been analyzed too, observing the liquid albumen volume and income performance, the solid albumen thickness, Total Soluble Solids (TSS), Titulable Total Acidity (TTA), the TSS/TTA relation and pH. According to the data gotten in the present work, the harvest of fruits from inflorescences emitted during the winter time, in the Baixada de Sepetiba area (Rio de Janeiro), must be carried through the period between the 6th and 7th months of development. The fruits reach its maximum size between the 7th and 8th months, the fruits have a round shape between the 5th and 7th months, with bigger weight between the 7th and 9th months, greater volume of liquid albumen between the 6th and 7th months and greater income of liquid albumen (%) between the 5th and 6th months. When compared with fruits proceeding from the local market, the fruits with 6 and 7 months old had gotten compatible arithmetic mean, with characteristics as recommended in the technician regulation of coconut water identity and quality settings (Normative Instruction n?39/2002 M.A.P.A.). / O presente trabalho foi realizado no Laborat?rio de P?s-Colheita do Departamento de Fitotecnia Instituto de Agronomia da UFRRJ, com objetivo de avaliar a influ?ncia da idade sobre os constituintes de frutos de coqueiro an?o-verde em infloresc?ncias emitidas no per?odo do inverno, na regi?o da Baixada de Sepetiba, e determinar o ponto de colheita ideal para consumo do alb?men l?quido dos frutos in natura. Inicialmente, foram marcadas as infloresc?ncias e tomadas amostras do 4? m?s at? o 12? m?s ap?s a emiss?o da infloresc?ncia. Em seguida, foram adquiridos frutos na CEASA-RIO, provenientes de diferentes regi?es produtoras (Linhares/ES, Rio Bananal/ES, Itagua?/RJ e Santa Cruz/RJ) e comparadas com frutos colhidos no 6? e 7? meses no experimento anterior. Foram realizadas avalia??es quanto ?s medidas externas (Comprimento, Largura e Rela??o Comprimento/Largura) e internas (Comprimento e Largura da cavidade interna; e Rela??o Comprimento/Largura da cavidade interna), foram avaliados o volume do alb?men l?quido, rendimento do alb?men l?quido, espessura do alb?men s?lido, S?lidos Sol?veis Totais (SST), Acidez Total Titul?vel (ATT), rela??o SST/ATT e pH. Pelos dados obtidos no presente trabalho, a colheita de frutos a partir de infloresc?ncias emitidas no per?odo de inverno, na regi?o da Baixada de Sepetiba (RJ), devem ser realizada no per?odo do 6o at? o 7o m?s de desenvolvimento. Os frutos atingem tamanho m?ximo entre o 7? e 8? meses, s?o frutos mais arredondados entre o 5? e 7? meses, com maior peso entre o 7? e 9? meses, maior volume do alb?men l?quido entre 6? e 7? meses e maior rendimento do alb?men l?quido (%) entre o 5? e 6? meses. Quando comparados com frutos provenientes do mercado, os frutos com 6 e 7 meses obtiveram m?dias compat?veis e com caracter?sticas preconizadas no regulamento t?cnico para fixa??o de identidade e qualidade da ?gua-de-coco (Instru??o Normativa n?39/2002 M.A.P.A.).
