| Abstract: | This paper discusses the effects of freezing process on changes of water absorption rate and cooking hardness of black beans.Black beans underwent the process of different soaking times,freezing temperatures and freezing times,and then dried by hot air to study changes of their water absorption rate during rehydration,as well as changes of their hardness during cooking.Results indicate that the optimal processing parameters are 6 h soaking,7 d freezing at-20 ℃,which could significantly improve the water absorption rate in rehydration and decrease cooking hardness of black beans. |
