Abstract:

Physico-chemical (hardness, water activity, fragmentation ratio and swelling degree, crystallinity, TPA structural properties) and microbiological properties of steamed and steam-baked bread stored at 25 ℃ during storage were compared to explore the effect of processing method on the quality of products and the retrogradation mechanism. Steam-baked bread had more excellent function in delaying retrogradation, attenuating aging, preventing from microbial invasion and extending storage period.

Key words: steamed bread, physico-chemical and microbial properties, rheology, microstructure
