عنوان المقالة:تقييم جودة حفظ ثمار التين الشوكي باستخدام بعض مواد التغليف Evaluation of Quality of Storage of Prickly Pear (Opuntia Ficus Indica (L.)) Using Two Packaging Methods
This research conducted (1) Objectives: to study the effect of preservation methods and packaging materials on the quality and safety of Prickly pear (PP) during the storage period. Across sectional descriptive study conducted on Palestine. (2) Materials and Methods: Fruits were hand-harvested, divided into Control, and Storage in refrigeration at 8c grouped with two material packaging in plastic (Polystyrene, Polyethylene terephthalate) and Carton (Tissue paper, Kraft paper). The fruits were stored for three months. chemical and microbial quality were evaluated at zero time and during storage. (3) Results: The samples wrapped in tissue paper showed a gradually significant decrease in Total Sugar and Brix by an increase in time during storage, and the samples deteriorated as it falls to 8.43 % after the second month. The samples that were wrapped in Kraft paper also showed slight decreases in the total sugar, Protein was not affected by the storage period in refrigeration, and all samples showed a gradually significant decrease in pH with statistically significant. Visual symptoms of chilling injury on fruits appeared after the second month of storage in refrigeration. (4) Conclusion: wrapping by Kraft paper kept the PP fruits in refrigeration without spoilage for two months.
