The postharvest phase plays a pivotal role in the preservation of fruits and vegetables, significantly influencing their quality and shelf life. With approximately one-third of global food production lost or wasted annually during postharvest and processing stages, addressing this challenge is imperative for food security, economic stability, and environmental sustainability. This research delves into the realm of postharvest storage techniques, specifically focusing on controlled atmosphere storage, modified atmosphere packaging (MAP), and conventional refrigeration, and their impact on reducing food loss. The postharvest period is a critical phase in the agricultural supply chain, significantly influencing the quality, safety, and shelf life of fruits and vegetables. Globally, one-third of food production is lost or wasted during postharvest and processing, posing challenges to food security, economic stability, and environmental sustainability (FAO, 2022). This research investigates the impact of postharvest storage techniques on mitigating food loss, with a focus on controlled atmosphere storage, modified atmosphere packaging (MAP), and conventional refrigeration. The study employs a randomized complete block design, encompassing diverse produce, including apples, tomatoes, and leafy greens. Through sensory analysis, nutritional assessment, and economic and environmental impact evaluations, the research aims to provide insights into the efficacy of these storage methods. Preliminary results suggest that controlled atmosphere storage outperforms other techniques in preserving sensory attributes, nutritional content, and extending shelf life. The economic and environmental analyses underscore the sustainability and economic viability of controlled atmosphere storage. This research contributes valuable knowledge to the ongoing discourse on reducing food loss, enhancing food security, and fostering sustainable postharvest management practices in the agricultural sector.
