ABSTRACT - The production of Hancornia speciosa Gomes, in Brazil, has increased significantly in recent years, with a concomitant increase in post-harvest losses, making it important to find out new techniques that contribute to extend the shelf life of this fruit without altering its physical, sensory and nutritional characteristics. The present study aimed to apply biodegradable coatings made from chitosan, whey protein, lactic acid and cassava starch to H. speciosa, as well as to assess their efficiency on the shelf life of the fruits. For that, physico-chemical analyses were performed to determine the pH, acidity, ºBrix, phenolic compounds, vitamin C and moisture content. The coatings with 1 % of chitosan, 4 % of whey protein, 3 % of cassava starch and 1.5 % of lactic acid presented satisfactory results at ambient temperature (25 ºC), delaying the ripening process, when compared to the controls.

RESUMO - Efeito de coberturas biodegradáveis no tempo de vida útil de Hancornia speciosa -  A produção de mangaba (Hancornia speciosa Gomes), no Brasil, tem aumentado consideravelmente nos últimos anos e, paralelamente a esse grande volume produzido, há elevado percentual de perdas, o que torna necessário o conhecimento de novas técnicas que contribuam para estender o tempo de vida útil dos frutos sem alterar suas características físicas, sensoriais e nutricionais. Objetivou-se aplicar coberturas biodegradáveis de quitosana, proteína do soro de leite, ácido lático e fécula de mandioca em mangaba, bem como avaliar a sua eficiência na preservação do tempo de vida útil dos frutos. Para isso, foram realizadas análises físico-químicas de pH, acidez, ºBrix, compostos fenólicos, vitamina C e umidade. As coberturas com 1 % de quitosana, 4 % de proteína do soro de leite, 3 % de fécula de mandioca e 1,5 % de ácido lático apresentaram resultados satisfatórios em temperatura ambiente (25 ºC), retardando o amadurecimento, em relação aos controles.
