Resumen
Descripción
Most of the external injures on produce are mainly caused at harvest and along the postharvest handling chain. Impacts, vibrations and compression forces result in damages that devalue the product for the fresh market. Some citrus species are remarkably susceptible to an epidermal blemish, oleocelosis, a characteristic disorder resulting from mechanical forces. In the present work two tangerine cultivars, Ponkan and Michal were submitted at lab facilities to compression forces of up to 60N to identify effects on internal quality and oleocelosis and decay incidence. Both cultivars had noteworthy losses on titratable acid and ascorbic acid after seven days at room temperature of the compression treatment. Cv. Ponkan is more susceptible to oleocelosis incidence probably because of a higher number and more superficial oil glands facilitating their rupture.
