| Outline of Final Research Achievements |
This study aimed to clarify the mechanism by which soybean whey improves the physical properties of protein-rich foods. In particular, we focused on dehydrin, a protein that is known to be expressed following drought and/or chilling stress. As a result, two kinds of dehydrin (26 and 31 kDa in size, respectively) were found in soybean whey. Interestingly, the 31 kDa dehydrin had higher thermostability than its 26 kDa counterpart. Furthermore, the 31 kDa dehydrin protected protein-rich foods against denaturation by freezing. In addition, we found that the 31 kDa dehydrin had an activating effect on other proteins.
