The Thawing Characteristic of Frozen Tofu under High-Voltage Alternating Electric Field

الملخص EN

To systematically and comprehensively investigate the high voltage alternating electric field (HVAEF) thawing processing, we investigated the high-voltage electric field thawing characteristic of the frozen tofu at different voltages for alternating current (AC).

The thawing time, thawing loss of frozen tofu, and specific energy consumption (SEC) of HVEF system were measured.

Seven different mathematical models were then compared to simulate thawing time curves based on root mean square error, reduced mean square of deviation, and modeling efficiency.

The results showed that the thawing rate of frozen tofu was notably greater in the high-voltage electric field system when compared to control.

Both Linear and Quadratic models were the best mathematical models.

Therefore, this work presents a facile and effective strategy for experimentally and theoretically determining the HVAEF thawing properties of frozen tofu.
