Global food systems face a paradox: rising demand and widespread hunger coexist with massive food waste, especially fresh produce. Short shelf life, poor forecasting, and lack of transparency lead to unnecessary disposal, contributing to greenhouse gas emissions and sustainability challenges. Consumers also lack reliable information on freshness and nutritional value, further worsening waste. Hence, embodiments of present disclosure provide a method and system for traceability, quality assessment and end of life recommendations of a food item. Initially an image of the food item is captured and a machine-readable tag on the food item is scanned to retrieve traceability data. Then, using trained Visual Language and physics-based models, visual and biochemical features are analyzed to compute ripeness, shelf life, and freshness scores. Further, usage recommendations and end-of-life options are recommended, including recycling guidance for packaging and upcycling opportunities for leftovers. This integrated approach ensures transparency, optimizes consumption, and supports sustainability.
