“…No entanto, para a mangaba, Silva et al (2009) observou um ligeiro aumento do teor de vitamina C com o amadurecimento dos frutos. Estes fatos comprovam que muitos frutos do cerrado podem apresentar heterogeneidade de forma, cor e atributos físicoquímicos, também apontados por outros autores (DIB TAXI et al, 2003, BORGES et al, 2010.…”

Estudos visando aprimorar a tecnologia de pós-colheita da mangaba se fazem necessários em função da alta perecibilidade da fruta e falta de tecnologias de transformação adaptáveis às condições de microempresas. Nesse estudo frutos de mangaba com três estágios de maturação foram caracterizados quanto a suas propriedades físicas e químicas, além disso foram avaliadas diferentes formas de despolpamento dos frutos em função do rendimento e características da polpa. As características físicas dos frutos determinadas foram o comprimento, diâmetro, massa específica aparente, volume e massa específica. Determinou-se o uso de prévia redução de tamanho dos frutos em multiprocessador sob aquecimento e dois tipos de peneiras em extrator, tipo escovas: com 0,8 e 0,5 mm de diâmetro de abertura de malha. A massa foi o parâmetro físico estudado que apresentou a maior irregularidade, variando entre 9,96 e 67,8 g por fruto. Houve aumento do conteúdo de vitamina C no transcorrer do processo de maturação dos frutos de mangaba do Cerrado atingindo 59,16 mg 100 g-1 em frutos maduros. Nas operações de despolpamento avaliadas verificou-se que o branqueamento e a trituração prévia dos frutos não aumentaram o rendimento de polpa, que foi expressivo, em torno de 77%, indicando que a mangaba é um fruto promissor para a agroindústria. Palavras-chave: Cerrado, polpa de fruta, despolpamento, frutos tropicais. Mangaba (Hancornia speciosa Gomes) fruit characterization and study the pulp extraction processes ABSTRACT Studies to improve mangaba post-harvest technology are necessary due to the highly perishable fruit and lack of adaptive processing technologies to the conditions of small businesses. In this study, mangaba fruits with three maturity stages were characterized for their physical and chemical properties; and were also evaluated different pulping technologies of fruits on pulp yield and characteristics. The length, diameter, apparent specific mass, volume and density of mangaba fruits were measured. The use of previous reduction in fruit size with multiprocessor under heating and two kinds of sieves extractor brushes type: 0.8 and 0.5 mm mesh opening diameter were tested. The fruit mass was physical property with the highest range of variation (from 9.96 to 67.8 g per fruit). There was increase in the vitamin C content during the maturation process of mangaba fruits reaching 59.16 mg 100 g-1 in mature fruits. In the evaluated pulping technologies found that bleaching and prior pressing of the fruits did not increase the pulp yield, which was significant (77%), indicating that the mangaba is a promising fruit for agribusiness.

“…However, native fruit species are heterogenous in vegetative and reproductive aspects and need to be studied to be establish selection criteria such as fruit color, size, width, etc. (Borges et al 2010). These variations are important indicators of genetic variability to be exploited in breeding programs (Clement 2001).…”

“…Its recalcitrant seeds (Delgado and Barbedo 2007) have been little studied regarding maturation, dispersal and physiology, making difficult technological development for plant production. In Eugenia species, great physical and physiological variation during fruit and seed development and maturation is observed (Silva et al 2001, Pio et al 2005, Avila et al 2009, Cardoso and Lomônaco 2003, Borges et al 2010, Braz and Mattos 2010, Lamarca et al 2011. These variations show the adaptive ability of the genus to unpredictable, heterogeneous or transitional environments (Cardoso and Lomônaco 2003).…”

This study aims to analyze the maturation and dispersal of Eugenia pyriformis Cambess. seeds produced in different years, and the influence of variation in thermal and hydric environment on seed physical and physiological characteristics at dispersal. Fruits at different developmental stages were harvested in the city of São Paulo between 2003 and 2010, as well as in the cities of Campinas and Lavras, in 2009 and 2010 and analyzed for size and color. The seeds were extracted from the fruits and their dry mass, water content, germination and vigor were assessed. Results showed that seed maturation is unsynchronized to the maturation of the fruit, taking 45 days on average (430 growing degree-days), longer in rainy times or lower temperatures. Seeds with higher physiological quality were produced in rainy years and when the temperature range was larger. We concluded therefore that hydric and thermal environmental variations during development influence the maturation of Eugenia pyriformis seeds and are able to determine the formation cycle and the final seed quality.
