Star apple (Chrysophyllum cainito) is popularly cultivated in Mekong region. Its pulp has strong sweet taste with antioxidant constituents contributing to various phytochemical and functional advantages. However this fruit has a short shelf life due to its perishable nature. It’s necessary to have appropriate way to extend its commercial distribution. Modified atmosphere packaging can be considered as a proper alternative to store this perishable fruit. Purpose of this research focused on the application of modified atmosphere packaging (MAP) to prolong shelf-life of star apple fruit. Weight loss (%), firmness (N), total soluble solid (oBrix), and vitamin C (mg/100g) were the main variables applied to observe this valuable fruit during 21 days of storage. Under MAP (30% CO2, 15% O2, 55% N2), star apple fruit could be extended to 18 days regarding to the weight loss, firmness, total soluble solid, and vitamin C values. Our finding contributed a basic foundation for more further studies on other tropical fruits and vegetables. Keywords: Chrysophyllum cainito, Modified atmosphere packaging, Weight loss, Firmness, Soluble solid, Vitamin C.
