Resumo: Pineapple (Ananas comosus Mill.) is exposed to injuries caused by low temperature during the refrigerated storage. The post-harvest application of Ca may contribute to reduce a number of physiological disorders. In this work, the influence of the postharvest application of 2% CaCl2 associated with hydrothermical treatment (38oC and 40oC) for 10 and 20 minutes, on the chemical composition (enzymes, phenols), and susceptibility to internal browning of pineapple 'Smooth Cayenne' fruits was studied. The fruits were stored at 9oC and 90% relative humidity for 15 days. The evaluations were performed seven days after removal of the fruits from the refrigerated conditions. The immersion of the fruits into a 2% CaCl2 solution reduced the index of internal browning and diminished the activities of the enzymes polyphenoloxidase, peroxidase and phenilalanine ammonium lyase, as well as the content of phenolic compounds when associated with the hydrothermic treatment regardless to the immersion period.

A aplicação, pós-colheita, de Ca pode contribuir para reduzir vários tipos de desordens fisiológicas. Neste trabalho, verificou-se a influência da aplicação, pós-colheita, de CaCl2 a 2%, associada ao tratamento hidrotérmico (38oC e 40oC) por 10 e 20 minutos de imersão, na composição química (fenólicos e enzimas), e na suscetibilidade ao escurecimento interno do abacaxi (Ananas comosus Mill.) cultivar Smooth Cayenne. Os frutos foram armazenados a 9oC e umidade relativa de 90% por um período de 15 dias. As avaliações foram efetuadas sete dias após a retirada dos frutos das condições de refrigeração. O tratamento dos frutos com CaCl2 reduziu o índice de escurecimento interno, conferindo menor atividade das enzimas polifenoloxidase, peroxidase e fenilalanina amônio liase e reduzindo o teor de compostos fenólicos na polpa quando associado ao tratamento hidrotérmico, independentemente do tempo de imersão.
