Shelf life of food product is important information for consumers. Product development of instant porridge that enriched with inulin as a prebiotic and expected to have a role in increasing calcium absorption in infants with aged 6-24 months. This study aimed to determine the shelf life of instant porridge products. The methods included in this research: (1) production of instant porridge products, (2) packaging with aluminum foil and polyethylene plastic, (3) stored at temperatures of 15°C, 30°C and 45°C which observed for 35 days with 7- day intervals, (4) analyzes of moisture content, protein content, total plate count, and organoleptic responses to critical responses, (5) analysis data was processed using the Arrhenius model ASLT method. Research results showed that instant porridge products stored at a temperature of 55°C were dropped by panelists on the 15th day. Instant porridge products with aluminum foil packaging have the longest shelf life with the lowest activation energy on protein content parameters with shelf life held at 15°C was 358 days, at 30°C was 214 days and at 45°C was 143 days. The recommendation for instant porridge should be packed using aluminum foil with storage temperature of 15°C.
