RESUMO-a aplicação de coberturas comestíveis em frutas e hortaliças deve ser precedida de testes que busquem a formulação que melhor se adapta àquele produto. o objetivo deste trabalho foi determinar a composição ideal da cobertura comestível à base de cera de carnaúba adicionada de prebiótico a ser aplicada em uvas variedade Thompson, armazenadas sob refrigeração. após a seleção, os frutos foram higienizados e procedeu-se à aplicação de soluções aquosas de cera de carnaúba adicionadas de Fruto-oligossacarídeo (FoS). Foram testadas treze formulações, utilizando as combinações de 50; 33; 25 e 0% (v/v) de cera de carnaúba e 30; 20; 10 e 0% do FoS (p/v). Durante 25 dias, foram avaliados parâmetros de textura, físico-químicos e físicos. os parâmetros de textura avaliados sofreram alterações durante o período do estudo, mas sem evidências de terem sofrido interferência das coberturas aplicadas. as formulações que se mostraram mais promissoras para futuras aplicações comerciais foram dos tratamentos B (50% de cera, 20% de FoS), K (25% de cera, 10% de FoS) e l (25% de cera, 0% de FoS). Termos para indexação: parâmetros físico-químicos, avaliação de textura, cobertura comestível, pós-colheita. IDEAL COMPOSITION OF FILM SOLUTION ADDED TO PREBIOTIC, APPLIED IN 'THOMPSON' GRAPESABSTRACT -the application of edible coatings for fruits and vegetables should be preceded by tests that seek the formulation that best fits that product. The objective of this study was to determine the ideal composition of edible coating based on carnauba wax added to prebiotic to be applied on grapes Thompson variety, stored under refrigeration. After selection, the fruits were cleaned and proceeded to apply the aqueous solutions of carnauba wax added to fructooligosaccharides (FOS).Thirteen formulations were tested, using the combinations 50, 33, 25 and 0% (v/v) of carnauba wax and 30, 20, 10 and 0% of the FOS (w/v). For 25 days, texture, physicochemical and physical parameters were evaluated. The texture parameters were changed during the study period, but no evidence have been influenced the coverage applied. The tested edible coatings did not alter the parameters evaluated of the Thompson grapes. The formulation which showed the most promising for future commercial applications were the treatment B (50% wax, 20% FOS), K (25% wax, 10% FOS) and L (25% wax, 0% FOS).
