An ideal emergency food must be able to fulfill the basic energy requirement of human which is equal to 2100 kcal per day, convenient and easy to distribute. This research aimed at contributing to the creation of healthy, nutritious and safe emegency food in the form of canned rice. Rice was chosen as the major staple food in Indonesia. Besides, to enrich the nutrition content of the product, eggwhite powder and margarine were added as the source of protein and fat. In the first step, the 4 formula were developed based the results of proximate analysis on raw materials content. All of the 4 formula were hypothesized to be able to fulfill the standard of energy distribution of protein (10-15%), fat (35-45%) and carbohydrate (40-50%). The 4 formula were canned and sterilized at 121.1oC for 40 minutes while the Fo value of this product was determined 15 minutes based on heat penetration test results. The best formula was selected based on several criteria which were sensorical properties, physical properties (color and texture) and also final proximate analysis results. The selected formula was Formula IV which contained 30% of carbohydrate, 6% of protein and 10% of fat and received the highest hedonic rating from 70 untrained panelists. The total energy contribution from the selected formula was 600 kcal and it is recommended to consume this product at least 3-4 times per day to fulfill the daily energy requirement. The last phase of this research was shelf life determination of seleted formula by using Accelerated Storage Study (ASS) for 6 weeks with sensorical properties (color, aroma, taste and texture) using 6 trained panelists and physical properties (color and hardness) observed. Based on the shelf determination using texture as the critical parameter when stored at 30oC, the shelf life of this product was projected up to 516 days and the followed the first order reaction kinetics
