Despite growing market share, northern growers contend with significant operational vulnerabilities. Papaya is a delicate, climacteric fruit; it continues to respire and ripen quickly after detachment from the mother tree. Exposure to mechanical impacts or temperature swings during long hauls down National Route 34 causes rapid bruising and fungal decay from Colletotrichum species (anthracnose).
The primary bottleneck sits inside regional packinghouses. While large citrus companies operate automated optical sorters and advanced cold chains, many independent mamón producers still sort fruit manually over padded tables. Pre-cooling infrastructure remains sparse across rural Jujuy. Loading fruit into long-haul trailers before pulling core pulp temperatures down to 10, 12°C (50, 54°F) leads to premature skin softening during transport.

Transport logistics introduce further headaches. Because volumes from individual farms rarely fill whole tractor-trailers daily, growers frequently combine shipments with bell peppers, tomatoes, or eggplants. Mixing cargo with different respiration rates and temperature tolerances compromises produce quality. Addressing these cold-chain gaps represents the main hurdle for regional producers aiming to surpass imported Brazilian product in premium supermarket tiers.
