    The cagaita is a native fruit of the cerrado, of high perishability, and for postharvest conservation of the fresh fruit, methods are used to increase its life cycle. In the present study, edible coatings are used, a technique that aims to control the loss of mass through transpiration reduces gas exchange, increases the shelf-life, improves the appearance, preserves the structural integrity and mechanical properties. The study aims to evaluate the influence of coatings based on biopolymers on the maturation of cagaita during storage. The factorial scheme 3 x 4 was used, with three treatments - without coating, polysaccharide coating and protein coating, four evaluation points - with an interval of 2 days, stored at 25 ºC. The fruits were submitted to weight loss, pH, titratable acidity, soluble solids, and ascorbic acid evaluations. There was no influence of the time factor in the present study, and for titratable acidity, ascorbic acid, soluble solids, and pH, there was no significant difference between treatments. Observing the content of soluble solids, the main indicator of ripeness, which varies from 5 to 7 ºBrix, it was concluded that the fruits did not ripen

    1 recurso en línea (páginas 286-293) : ilustraciones color.Brazilian Cerrado is one of the largest biomes in the world and is considered the richest one. Mangaba fruit is representative of this biome, but it is highly perishable. The aim of this study was to evaluate the application of edible coatings on post-harvest mangaba. Fruits with a good appearance and absence of injuries were used. The experiment was done with a factorial scheme (3 treatments × 6 storage periods). After sanitization and drying, the mangabas received the treatments: (1) whey protein coating; (2) corn starch coating; and (3) no coating (control). Trays with the fruits were stored at room temperature (25°C). Mass loss, pH, total soluble solids (TSS), total titratable acidity (TTA), firmness and ascorbic acid levels were evaluated after 0, 2, 4, 6, 8, and 10 days of storage. The data were evaluated with analysis of variance, Tukey test and regression. The edible coating with whey protein obtained satisfactory results in the conservation of mangaba, showing good results for the TSS/TTA ratio (16) and vitamin C (116 mg/100 g). The coatings influenced the shelf-life and post-harvest characteristics of this fruits, but the coating with whey protein was the most indicated for mangaba.El Cerrado brasileño es uno de los mayores biomas del mundo y considerado el más rico. La fruta mangaba es representativa de este bioma pero es altamente perecedera. El objetivo de este estudio fue evaluar la aplicación de recubrimientos comestibles en la poscosecha de mangaba. Se utilizaron frutas con buen aspecto y ausencia de lesiones. El experimento se realizó en esquema factorial (3 tratamientos × 6 períodos de almacenamiento). Después de la desinfección y secado, las mangabas recibieron los siguientes tratamientos: (1) recubrimiento de proteína de suero; (2) recubrimiento de almidón de maíz; (3) sin revestimiento (control). Las bandejas con los frutos se almacenaron a temperatura ambiente (25°C). Se evaluaron los niveles de pérdida de masa, pH, sólidos solubles totales (SST), acidez total titulable (ATT), firmeza y ácido ascórbico en periodos de almacenamiento de 0, 2, 4, 6, 8 y 10 días. Los datos fueron evaluados mediante análisis de varianza, prueba de Tukey y regresión. El revestimiento comestible con proteína de suero obtenido resultados satisfactorios en la conservación de mangaba, mostró buenos resultados para la relación SST/ATT (16) y vitamina C (116 mg/100 g). Los recubrimientos influyeron en la vida útil y en las características pos cosecha de estas frutas, pero el recubrimiento con proteína de suero de leche es el más indicado para la mangaba.Bibliografía: y webgrafía: página 29

    ELABORAÇÃO E AVALIAÇÃO SENSORIAL DE SORVETE DIET E SEM LACTOSE DE MANGABA ENDÊMICA DO CERRADO

    A mangaba é um fruto do cerrado, rica em ferro e fonte de vitamina C mas com alta perecibilidade. Com o objetivo de reduzir os desperdícios e aumentar o processamento desse fruto, foi elaborado um sorvete a partir da polpa do fruto, em uma formulação integral e em outra sem lactose e diet, para atender a consumidores com restrições alimentares. Os sorvetes foram analisados quanto ao pH, sólidos solúveis, acidez titulável e derretimento. E submetidos a análise sensorial por 30 provadores, que mostraram aceitação de ambos, mesmo sendo possível detectar diferença entre eles.  A produção de sorvetes é viável para aumentar o processamento de mangaba e evitar desperdício
