Post-harvest losses of 'Cruiser' cantaloupe reach similar to 15% in arid regions of Mexico, representing substantial wasted water and embedded greenhouse-gas emissions. This study presents an open-access, low-temperature maceration protocol for converting cosmetically rejected fruit into a carotenoid-rich spirit at rural scale. A 5-day maceration at 20 degrees C (15% pulp, 20% v/v ethanol) preserved color, beta-carotene, and antioxidant capacity over 90 days of storage. Shelf-life predictions beyond this period are model-based and require long-term validation. Trained assessors characterized the beverage with a favorable aromatic profile driven by fruity esters and floral terpenes. Life-cycle results indicated lower cradle-to-gate impacts than reference mango spirits, and composting of pomace generated a mature soil amendment. A simplified techno-economic scenario suggests potential for rural processing but excludes taxation, licensing, and regulatory compliance; thus, economic feasibility cannot yet be confirmed. Overall, this study provides a proof-of-concept pathway for valorizing cantaloupe waste through low-temperature maceration and identifies critical analytical, regulatory, and economic aspects needed for future scale-up.
