Abstract

Fruits are an essential part of our nutrition. Citrus spp., which are mostly found in the Mediterranean basin are the most common fruit consumed by people. In today's environment, postharvest quality retention in supply chain management is a major concern and a critical issue. Fruit continues to breathe after being picked, and the high temperatures in the field and during transportation to pack houses make this process difficult. The fruit shelf life is shortened as a result of the spread of pathogens, which is harmful to the quality of fruits after harvest. Postharvest losses can result in significant waste, accounting for 30 to 50% of the overall crop, and are mostly brought on by infections and metabolic abnormalities of fruits. The right handling, treatment, storage, and transportation of harvested food determine the postharvest technological innovation's primary objectives of maintaining quality and prolonging shelf life. To further reduce the accumulation of artificial pesticide residues on fruit surface and the implications of fungicide waste disposal, new, eco - friendly methods must be used. This review critically evaluates the most efficient and ecologically friendly techniques, as well as cutting edge post-harvest processing and storage technologies in citrus fruits variety sweet orange.

Conclusion

There is a risk to human and environmental health as well as considerable financial expenses now that pathogen resistance has been connected to the use of synthetic fungicides to minimize pathogen infection. Finding alternative, secure control methods is therefore given more significance. To trigger a fruit's inherent defenses is one such strategy. An effective approach for assessing as well as grading the chilling and freezing damages in orange was the forward-scattering biospeckle imaging method. Utilizing edible coatings and more modern techniques, such as layer-by-layer coatings and their synergistic effects, are far more effective at increasing the shelf life of food. Certain post-harvest illnesses and disinfections have also been reported to be treated by essential oils and plant extracts. The phenols, antioxidants, and senescence delaying effects of LED light on fruits have improved in recent years. It is also possible to apply nanocomposite materials and antibacterial compounds to the surface. By using bioagents to activate natural antagonistic mechanisms, diseases can be effectively managed while preserving ecological equilibrium. Some recently developed technologies, such as cold plasma and irradiation, can reduce pest infestations in quarantine areas while simultaneously improving product quality. Therefore, the combined benefits of these technologies may reduce postharvest losses and maintain quality during supply chain management.
