Abstract: In this paper, the effect of thermo-tolerant xylanase from thermophilic bacterium Geobacillus sp. PZH1 on the quality and shelf-life of steamed bread was investigated. The results showed the thermo-tolerant xylanase significantly elevated the volume of steamed bread and improved its textural properties. Meanwhile, the xylanase restrained the bacterial growth and prolonged the shelf-life of steamed bread.

Key words: thermophilic bacterium, thermo-tolerant xylanase, bread quality, shelf-life
