  Traditional packaging materials for food include glass, metal, paper, paperboard, and plastic. The stability of food antioxidants depends on storage temperature, storage time, and type of packaging material. After stress exposure, gene expression is tightly controlled and reversible using various molecular pathways that are very dependent on specific stress and organism type. The current study examined the stability of lipid peroxidative, stress genes, and antioxidants in fruits and vegetables stored in various packaging materials under refrigeration. A plastic container, a brown paper bag, and a ziplock bag were utilized to store tomatoes and lemons under refrigeration (5–6 ℃), and the parameters were examined on Day 0 (control), Day 1, and Day 15. The values of the parameters were estimated via various technical methods, while the expressions of genes were determined using the process of polymerase chain reaction and visualized using agarose gel electrophoresis. The stability of antioxidants, lipid peroxidative, and electrolyte levels of the tomatoes and lemons stored in the various packaging materials were found to be significantly altered on Day 15 compared with those of the control. In addition, the expressions of stress genes of the tomatoes stored under refrigeration in the various packaging materials, especially the plastic container, were significantly downregulated on Day 15 compared with those of the control. In conclusion, no packaging materials are suitable for retaining the levels of antioxidants, lipid peroxidative, and stress genes of food materials under refrigeration.
