In conventional defrosting methods such as running water and microwave defrosting, dripping has arisen, affecting flavor and color, and so frozen foods have been evaluated poorly. Also, natural defrosting and refrigerator defrosting require at least two hours, and similarly dripping has arisen and so the reputation has been poor. The objective of the present invention is to perform defrosting of a frozen food such as meat or fish in a short period of time without using thermoelectricity such as electricity. [Solution] This food defrosting sheet is such that a powdered aluminum and a powdered ceramic are mixed with water, a high water absorption polymer or CMC (carboxymethyl cellulose), and hinokitiol, forming a gel, the result is introduced into a bag made of nylon, plastic, or an aluminum sheet, forming a soft sheet, which sandwiches a freezing subject food from the top and bottom, by which means contact area is increased, decreasing dripping arising during defrosting and reducing defrosting time using the heat-absorbing effect of the defrosting sheet for the heat of the frozen food, and so it is possible to decrease changes in color and flavor.
