Abstract : Mangoes are a key fruit in tropical regions, but they face post-harvest losses due to spoilage and shelf-life issues. This study investigated the effectiveness of zeolite as a low-cost alternative to preserve Manalagi mangoes. The Manalagi Mangoes were stored in a styrofoam box for 7 days, with different concentrations of treated zeolite (0, 25, and 50 percent). Firmness in kilogram per centimeter squared (kg/cm2) was used as a primary indicator of ripeness. The experiment showed that both treatments varied significantly from the mangoes with no treatment, with visible effects appearing from day 2. The 25% treatment performed comparably to the 50% treatment in retaining firmness starting on day 4. In conclusion, zeolite should be used as a non-toxic and widely available alternative to communities with a lack of access to refrigeration and Modern Atmospheric Packaging. Its adoption could help reduce postharvest losses in developing countries where refrigeration is limited.

Keywords : Zeolite, Firmness, Ethylene, Preservation, and Post-Harvest Losses.
