摘要：

In order to explore the change mechanism of frozen food quality in cold chain circulation, the glutenin in the dumpling wrapper was objected to analyze the changes of physicochemical and functional properties under the freeze-thaw cycles from-40℃ to 25℃. The result showed that emulsification and foaming ability increased, the solubility decreased while the surface hydrophobicity raised by freeze-thaw cycles; the free thiol contents dropped and HMW degraded, and the decreasing of random coil and a-helix were 8.25%, 18.67% respectively. All of these showed that the structure of protein was broken and functional properties reduced under the freeze-thaw cycles, which provided the reference for the study in mechanism of dumplings quality. ©, 2015, Chinese Institute of Food Science and Technology.
