Abstract: This study applied Weibull hazard analysis to determine of shelf-life, with UHT milk as experimental object. It also isscused the feasibility of applying physico-chemical Weibull hazard analysis to determine the shelf-life as well as the reliability analysis of commercial shelf-life. The sterilized commercial samples were divided into four experimental groups with commercial shelf-life of 45 days, stored at 25℃, 30℃, 35℃ and 40℃ respectively. The sensory, physico-chemical and bacterial tests were carried out at stated intervals.

Key words: shelf-life, Weibull distribution
