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.
