The goal of this work was to evaluate the use of pré-cooling, modified atmosphere and 1-MCP (1-methycyclopropene) on the postharvest quality of okra(Abelmoschus esculentus L. Moench) and jilo (Solanum gilo Raddi) stored under refrigeration. The PVC film was efficient in controlling the loss of fresh matter, regardless if the fruits were hydrocooled or not, keeping them firm. Control and precooled fruits without PVC appeared wilted by the second day of storage for okra and by the seventh days for jilo. The use of 1-MCP, before the wrapping with PVC, reduced the loss of fresh weight of jilo compared to control. Fruits of okra and jilo wrapped in PVC, regardless been precooled, has higher contents of chlorophyll compared to non wrapped fruits. Fruits of jilo treated with 1-MCP had higher content of chlorophyll compared to the remaining treatments at the third day of storage. Precooling and /or PVC film did not interfere with the content of carbohydrates ( starch and total soluble sugars), but immediately after the preccoling there was a reduction of starch breakdown. The was reduction in the rate of starch comsumption for jilo when treated with 1-MCP. At eleven days of storage there was yellowing for the jilo wrapped in PVC, but for the 1-MCP treated, regardless the concentration applied, the yellowing appeared ad fourteen days. There was higher development of chilling in okra stored without PVC, but at the end of storage the symptoms appeared in wrapped fruit, regardless if were precooled. No symptoms of chilling developed in jilo during storage. Thusd the use of PVC film and /or precooling helps in keeping the fruit quality, and, the use of 1-MCP before wrapping with PVC film, prolongs the shelf life at 10oC and 85% relative humidity.
