摘要:

分别对馒头进行自然冷却、冷风冷却、真空冷却、混合冷却(a.自然冷却与真空冷却相结合;b.冷风冷却与真空冷却相结合),比较不同冷却方法对馒头的冷却后品质、冷冻贮藏期品质、失水率、开裂率的影响以及冷却过程中的能耗,得出自然冷却与真空冷却相结合的混合冷却为馒头最佳冷却方法。

Abstract:

In this study, the effects of different cooling methods including natural cooling, cold air cooling and vacuum
cooling, and combinations of vacuum cooling with either natural cooling or cold air cooling on the quality of steamed buns.
Subsequently, changes in quality characteristics, percentage water loss and cracking incidence of steamed buns during further
frozen storage were examined. Moreover, comparison of power consumption among 5 cooling methods was performed. The
obtained results led to the conclusion that natural cooling combined with vacuum cooling was the best cooling method for
steamed buns.

Key words: steamed bun, cooling method, combined use of different cooling methods, quality, energy consumption
