| Abstract | ||||
| his study was carried out on cantaloupe fruits (Cucumis melo L. cv. Gal 152, Galia type) harvested at yellow green color stage in the winter of 2013 and 2014 seasons from a private farm at EL-Ismailia Governorate, to evaluate the effects of chitosan at 1000 and 2000 ppm, potassium permanganate sachets contained 2.5 and 5g per box and distillate water (control) on maintaining quality and storability of cantaloupe fruits during storage at 5 °C and 95% relative humidity for 28 days in addition to 2 days at 10 °C (shelf life conditions). Results showed that all postharvest treatments reduced weight loss %, the loss of TSS%, L. ascorbic acid and total sugars, had the higher values of firmness and general appearance as compared with untreated control during storage and shelf life condition. Cantaloupe fruits soaked in chitosan at 2000 ppm or packed with 5g potassium permanganate were the most effective treatments in this concern and gave fruits with good appearance after 21 days at 5° C plus 2 days at 10°C. The lower concentrations of these materials were less effective treatments in this concern. | ||||
