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
