Description
Summary:In order to increase the availability to consumers and add even more value to peaches (Prunus persica (L.) Batsch) and to identify which cultivars grown in tropical regions are more suitable for jelly processing, the objective of this study was to characterize and evaluate the influence of different peach cultivars ('Aurora', 'Biuti', 'Bonao', 'Centenario', 'Diamante', 'Douradao', 'Libra', 'Regis' and 'Tropical') cultivated in tropical regions on the physicochemical characteristics, rheological properties and sensory acceptance of the resulting jelly. The evaluated cultivars presented great variability among themselves in relation to the physical and physicochemical characteristics. The jellies elaborated from these cultivars; although, presenting great variability in relation to the physicochemical and rheological parameters, presented similar, high acceptance. All cultivars studied are suitable for processing and can be used for industrialization. Key words: Prunus persica (L.) Batsch, sensory quality, processing. Com o objetivo de aumentar a disponibilidade para os consumidores, agregar ainda mais valor aos pessegos (Prunus persica (L.) Batsch) e identificar quais cultivares cultivadas em regioes tropicais sao mais adequadas para o processamento de geleia, o objetivo deste estudo foi caracterizar e avaliar a influencia de diferentes cultivares de pessegueiro ('Aurora', 'Biuti', 'Bonao', 'Centenario', 'Diamante', 'Douradao', 'Libra', 'Regis ' e 'Tropical') cultivadas em regioes tropicais nas caracteristicas fisico-quimicas, reologicas e sensoriais da geleia resultante. Verificou-se que as cultivares avaliadas apresentaram grande variabilidade entre si em relacao as caracteristicas fisicas e fisico-quimicas. As geleias elaboradas a partir destas cultivares, embora apresentam grande variabilidade em relacao aos parametros fisico -quimicos e reologicos, apresentaram alta aceitacao. Conclui-se, que todas as cultivares estudadas sao indicadas para processamento e podem ser destinadas a industrializacao. Palavras-chave: Prunus persica (L.) Batsch, qualidade sensorial, processamento.
