Effect of cold storage and packaging to improve the quality of local orange fruits after harvest

الملخص EN

This study was carried out using two home-based refrigerators with a volume equal to 377 l each.

the storage duration of local orange fruits was five months, ranging from 1 / 12 / 2019 to 1 / 5 / 2020.

an experiment comprised two factors, including two levels of storage temperature at five °C and ten °C and three different types of packaging; non-packaging, packaging with a Polyethene bag and packaging with a paper bag.

the experimental design is a completely randomized design with five replications per treatment.

the mean values were compared using Duncan's test at a significance level (p = 0.05).

results showed that storage at five °C reduced the weight loss% and fruit damage% to 56.16% and 16.79%, respectively.

as for the packaging factor, paper bags showed the lowest value of weight loss fruit damage and the highest value of fruit juice was recorded, 11.18%, and 41.52%, respectively.

regarding the interactions between storage temperature and packaging types, the treatment combinations, five °C with paper bag packaging, achieved the lowest weight loss and fruit damage and the highest rate of fruit juice with percentages equal to 2.7%, 9.79, and 41.52%, respectively.

the same trend is actual for a combination of storage temperature at ten °C with paper bag packaging gave the highest percentage of fruit juice, 41.52%.

various storage temperatures at ten °c and Polyethene bag packaging revealed the highest ratio of total sugars, reaching 11.34%.
