Abstract

Papaya is a fruit with considerable economic potential in the tropics as there are domestic markets in producing tropical countries and export markets in the sub-tropical and temperate countries In Ethiopia, large quantity of papaya is wasted before it reach the target markets. Because papaya is naturally sensitive to postharvest injuries and mechanical damages due to its thin skin and climacteric type ripening nature. The use of modified atmosphere in combination with cool storage can successfully extend the storage life of papaya fruit. The high density polyethylene packaged fruits characterized by lower weight loss at ambient and evaporative cooler storage compared to the loss in non-packaged fruits stored at ambient condition, low density polyethylene bags maintained better weight compared to newspaper and banana leaf packaging materials. Packaged fruits had more number of marketable fruits than the non-packaged under both ambient and evaporative cooler conditions. The packaging materials of high density polyethylene bags and Low density polyethylene combined with evaporative cool storages have significant effect on maintain shelf life and postharvest quality of papaya compared with banana and news paper packaging materials. But the banana leaves and news paper packaging materials combined with evaporative cool storages also has good effect on maintaining shelf life and postharvest quality of papaya as compared with other packaging materials.

Highlights

The papaya, (Carica papaya L.), is a member of the family Caricaceae
Procedures include lowering temperature to slow respiration and senescence, maintaining optimal relative humidity to reduce water loss without accelerating decay, adding chemical preservatives to reduce physiological and microbial losses, and maintaining an optimal gaseous environment to slow respiration and senescence (Wills et al, 1989; Desi and Wagh, 1995).Packaging fruits is one of the most commonly used postharvest practice that puts them into unitized volumes which are easy to handle while protecting them from hazards of transportation and storage (Burdon, 2001)
Papaya fruits are sensitive to poor quality out turns and high postharvest losses if harvesting, treatments and handling techniques are inadequate or inappropriate

Summary

INTRODUCTION

The papaya, (Carica papaya L.), is a member of the family Caricaceae. It is believed to be native to southern Mexico, Guatemala, and Costa Rica (Teixeira da Silva et al, 2007). Objective General Object; To review effect of packaging materials and storage environment on postharvest quality of papaya. Effect Of Storage Temperature And Relative Humidity The function of a fruit or vegetable storage is to provide an environment that will permit produce to be stored as long as possible without deterioration of quality, which is a composition of flavor, texture, moisture content, and other factors associated with edibility. Tilahun and Kebede (2004) noted the effect of increasing storage relative humidity and reducing the temperature through a cooling process where evaporative cooling reduced the physiological weight loss in papaya compared to fruits stored under ambient conditions. Reduced rate of respiration and transpiration at lower temperature and higher relative (RH) humidity could be the reason for such a reduced rate of weight loss of fruits in the evaporative cooler storage
