Abstract:
The production of 'Rojo Brillante' persimmon, an astringent cultivar, has increased significantly during the last few years. Nowadays, the application of high carbon dioxide is the method used to remove astringency. It allows to commercialize fruit with crisp texture. Browning of flesh fruit during shelf-life is one of the major causes of losses to the industry. The influence of postharvest management in the appearance of the browning disorder has still not been studied. In the present work the effect of the deastringency treatment conditions, as well as the influence of the packing line process have been studied. According to the preliminary results obtained in this work, the most important factor involved in the incidence of browning is the mechanical damage suffered by the fruit in the packing line. Fruit susceptibility to browning was related to the degree of astringency of the fruit and thus to the level of tannins.
