摘要:

测定在25℃条件下储存期间馒头的理化性质和微生物指标的变化,探讨两种加工方法对产品的品质保存期的影响,揭示其抗老化机理。通过对硬度、水分活度、破碎率、膨润度、支链淀粉结晶度、TPA 质构特性、微观结构等理化性质及微生物指标等对比实验研究。结果表明,蒸烤馒头能更好的延缓淀粉的回生、老化,阻止其被微生物侵袭,延长其保质期。

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
