Abstract: Military compressed food was the primary variety in military food system.In order to study the relationship of hardness and temperature during storage,the compressed food was measured by sensory analysis and Weibull hazard analysis at 50 ℃ to determine the limit of hardness accept ability.The hardness predictive models were also developed.The results showed that the limit of hardness acceptability was 190 N,and the shelf-life was 40 d.
