“…Refrigeration is the most reliable and time test method available for extending the fresh condition of fruits and vegetables as it checks destructive activities of decay causing microorganisms and also slows down the normal process of deterioration. Ali et al (1994) showed that papaya fruits are susceptible to chilling injury in 10 to 15°C. According to Pastrana et al 2010 the ripe fruits stored at 25°C had more β carotene and rutin compared to fruits stored at 1°C low (chilling ) temperature negatively affected major carotenoids.…”

The main objective of this study was to increase the shelf life of fruits through vacuum packing. Papaya fruits were pretreated with waxing, oil application, purafil packets, tissue paper wrapping given along with control and were packed in 150 gauge thickness polyethylene film bags under vacuum and another set of these samples under without vacuum. The fruits were then stored at room and refrigerated temperature and analyzed for chemical changes. Results showed that the shelf life of the fruits increased under vacuum packing with room and refrigeration temperatures for one and four weeks respectively. The fruits packed without any pretreatment in 150 gauge polyethylene bags maintained the quality with minimum changes followed by waxing, purafil and oil application. During storage moisture, acidity, Vitamin C and total sugar decreased whereas reducing sugar and total soluble solids (TSS) increased during storage. The sensory qualities declined with the period of storage and temperature differences. The study concluded that vacuum packaging and refrigeration conditions increased the shelf life of the papaya fruits.
