“…Cooling is the main factor that slows down the metabolic processes, transpiration and tissue oxidation processes. At room temperature, asparagus retains an acceptable quality for 5 days (Irving and Hurst, 1993), but lowering the temperature to 2 °C extends the storage period to 14 days (Papoutsis, 2023). In general, the acceptable storage temperature for asparagus is below 4°C, but it should be above -0.8°C (ice crystallization temperature in asparagus) (Ando et al, 2019).…”

Storage is a crucial component of a sustainable and efficient food supply system. Reduction of postharvest losses and waste is a vital strategy to improve efficiency, ensure product availability, and reduce environmental impact. Asparagus (Asparagus officinalis L.) boasts a high nutritional value and complex of phytonutrients. Yet, the storage period for fresh asparagus is quite short, leading to rapid quality deterioration. An effective method to extend storage periods involves postharvest treatments using the natural biopolymer chitosan. The aim of the research was to assess the effectiveness of applying sustainable postharvest treatments based on chitosan and rutin, with a focus on losses and waste reduction during asparagus storage. The impact of the applied storage technology on the visual appeal and sensory attributes of asparagus, along with its effects on respiratory metabolism, weight loss, soluble solids, soluble carbohydrates, chlorophylls, and carotenoids, was systematically assessed. The findings indicate that the post-harvest treatment using chitosan and rutin effectively preserves the visual characteristics of asparaguswhen the storage period is prolonged to a week. A major advantage of this technology is a substantial reduction in waste, achieving the levels of 1.0-1.5%. The proportion of standard products post-storage ranged from 94.4% to 96.0%. The treatment with chitosan and rutin efficiently reduces weight loss by half and suppresses the respiration rate, leading to decreased losses in soluble solids, carbohydrates, chlorophylls, and carotenoids during storage. These outcomes underscore the effectiveness of the applied coating in impeding metabolic processes, resulting in minimized quantitative and qualitative losses in the product quality during a prolonged storage.
