Method for unfreezing frozen meat product

Abstract

The invention discloses a method for unfreezing a frozen meat product. The method comprises the following steps of putting to-be-unfrozen bulk frozen meat between two metal polar plates; soaking the metal polar plates and the bulk frozen meat for 60-90 seconds in saline water having a concentration of 1-3 percent; and applying alternating current with different voltages between the two metal polarplates according to the thickness difference of the bulk meat. The method can be used for unfreezing meat quickly, the frozen meat product unfrozen by the method has uniform temperature, little juiceis lost in unfreezing, and the taste of the meat product can be better maintained.

Description

technical field [0001] The invention relates to the technical field of food industry, in particular to a method for thawing frozen meat products. Background technique [0002] Freezing is a better way to keep meat quality stable, but frozen meat often needs to be thawed before use. The thawing process has an effect on the meat quality. Traditional thawing methods, such as air thawing and water thawing, rely on heat transfer from the surface of the meat to the interior, but the thawing time is too long, and the thawed meat products have poor taste. [0003] Microwave thawing is also a common thawing method. Its advantage is that the thawing speed is fast, but the temperature difference between the surface temperature and the center temperature of the meat after thawing is large, especially for thick meat. It is easy to cause the surface of the meat to be scorched, but the inside is still not defrosted. The reason for this phenomenon is that the microwave frequency is high,...

Problems solved by technology

Although this method has a fast thawing speed, it requires radio frequency equipment, and a high voltage of 6-8Kv is required between the plates, which is expensive and unsafe due to high voltage.
