Many people because of the eagerness to eat, will just buy back or just out of the freezer from the frozen meat thawed with hot water immersion, in fact, this is not scientific, the correct method is to soak in cold water, or will be placed in the frozen meat at 15 degrees to 20 degrees, so that it naturally thawed. This is because meat in the quick-freezing process, its combination of juices contained in the protein and organic acids are also completely moved into ice, meat slowly thawed, the crystallization of such juices will be re-thawed slowly. Reduced to juice into the meat fibers, so that the meat to restore the original nature of the meat to maintain the meat's original nutrients and delicious, if thawed with hot water, meat juice crystals melt quickly, too late to penetrate into the meat fibers and loss of white, thus losing a part of the protein and aroma taste substances, the use of this meat made of food, nutritional value is not high, taste is not good.

Scientific thawing method is the frozen fish, livestock, poultry and other food in cold water or placed in 4 ℃ ~ 8 ℃, so that the natural thawing. This is because meat food in the process of quick-freezing, its intracellular fluid and extracellular fluid quickly frozen into ice, the formation of meat fibers and cells in the middle of the crystals. This crystallization of juices is a most valuable protein and tasty substance. If thawed with hot water, not only will lose part of the protein and its flavor substances, more importantly, will generate a strong carcinogen known as propionaldehyde. Therefore, frozen meat must be thawed with cold water or make it slowly and naturally thawed.

Tell you a quick way to thaw frozen meat: Place the meat on a table, place the bottom of an aluminum tub on top of the meat, and maximize their contact surface. You can also use 2 aluminum tubs to sandwich the meat (upside down with one tub underneath, meat in the middle, and one tub on top). If you don't have aluminum pots, a copper or iron pot will work.
