Abstract:

Article Preview

Experiments were carried out to analysis optimization of freeze-thaw regression model with Response Surface Analysis Method. The optimal response result is: freeze temperature: -18°C, freeze time: 12.5h, thaw temperature: 57°C, released oil yield: 93.16%, total free oil yield rate: 89.28%. The mechanism of demulsification was studied using Micro-imaging, SEM cooling stage, DSC, FTIR spectrometer. DSSP was changed and part of hydrogen bond was broken and α-helix structure conversed to random coil during the freeze process were found the effective freeze-thaw method to destabilize the emulsion.
