Objective To study the influence of UV irradiation on the shelf life and quality of steamed bread. Methods The quality of steamed bread was determined by sensory evaluation and the shelf life of steamed bread was obtained by measuring the number of microorganisms on steamed bread surface. Results When the irradiation time was 7 s, the amount of UV light tube was 3, and irradiation distance was 5 cm, microorganism growth was obviously inhibited and the shelf life of steamed bread extended from 20 h to 40 h. Moreover, sensory score of steamed bread had no obvious changes. Conclusion Ultraviolet irradiation treatment has little impact on the quality of steamed bread, but it can significantly extend the shelf life of steamed bread.
