| Abstract: | Based on the previous discusses of the new thawing technology at low temperature by the HVEF, an experimental device has been established in this paper. An investigation is undertaken to determine the rules of quick thawing by HVEF by the thawing experiments of ice, bean curd and meat. 20% time, needed in normal method in ice (300 mL) thawing, is saved under the 24 kV/m of HVEF, and the same tendency in thawing process of bean curd and meat. The data support the hypothesis that the study in water existed comprehensively in food is signified for the thawing mechanism. |
