Rearch investigated ice crystallization in solution containing various high molecular weight substances by thermal response methods in a batch crystallizer. |
| Abstract: The kinetics of ice crystallization in various polymer solutions were studied by the thermal response method in a batch crystallizer. Polymers suppress the secondary nucleation of ice crystals, depending on the kinds of polymer and concentration. The decrease of the nucleation rate constant in polymer solutions was related to the increase of viscosity. The effects of polymers on the nucleation rate were also observed in solutions containing low molecular weight compounds. |
| Experimental Conditions: Dextran T2000, Dextran T500 , Ficoll400, Ficoll 70, dextran sulphate, ovalbumin, carboxy methylcellulose, polyethylene glycol, ovalbumin, skim milk were used with ice crystals measured with a microscope and viscosity measured with a B type rotational viscometer (Tokyo Keiki Seisakusho). Different ice crystals were formed with different compounds. |
