How to thaw frozen foods cooked the healthiest
We cook frozen in Food Most of the time using cold water immersion, the floods came, hot water thawing method, etc., resulting in dishes taste bad, ugly color, shape is not the whole, the phenomenon of more nutrient loss. So, how do thaw and cook frozen food?
About various types of food refrigeration and freezing of time in order to maintain food quality, inhibit the reproduction of bacteria, low temperature food storage methods to prevent deterioration of the primary means of corruption.
Current with the company to use the refrigerator or electric freezer, cold room temperature will control the 0 ~ 10 , the freezer temperature will reach -18 ~ -24 . Therefore, various types of food refrigeration and freezing time should be:
1. Vegetables food storage freezer. Leafy vegetables such as cabbage, rape, spinach, cabbage, etc. for 2 days; per cabbage for 5 to 7 days; fruits and vegetables such as tomatoes, cucumbers, eggplant, green peppers, summer squash 4 to 5 days; Beans Vegetables such as lentils, beans, cowpea, etc. 3 to 4 days; fungi foods such as all kinds of mushrooms, including shiitake mushrooms, mushroom, etc. 2 to 3 days.
2. All kinds of animal-based food storage freezer. Pork, beef chunks 3 to 4 days, small pieces of 2 to 3 days for 2 to 3 days mutton, chicken for 2 to 3 days, fish 1 to 2 days. Frozen storage, the food is placed in the freezer, and freezer temperature is generally -18 ~ -24 , so it takes longer food storage, and can do with food, with the check, with the place, such as pork meat, beef, lamb for 90 days, 120 days of chicken, fish for 90 days. But not long-term storage of frozen foods, if stored too long may cause food sour, or bad, this and Other food products Shelf-life, like, over the shelf life would deteriorate. So frozen food to eat a frozen period, to prevent the indefinite storage.
Thawing frozen foods and requirements of food cooked from the frozen state to the former, must be a thaw. Thaw is the reversal of the freezing process, which can freeze the food back to the fresh frozen state before.
Food thawing methods are: 1. Air-thaw method. There are two kinds, one will be removed from the freezer with frozen food into the freezer, thawing method of this long, but good quality food thaw, usually out at night, eat the next morning; Second, the frozen food from Remove the freezer, thaw on the indoor air, this thawing method greatly influenced by temperature. Air thawing method used should be noted that food can not be too long, especially in the summer of bacteria after thawing fast food, likely to cause food spoilage.
2. Water thawing method. Frozen food need food, the available water thawing. Because of the heat transfer performance of the water better than air, thawing time can be shortened. It should be noted that frozen food should not be direct contact with the water should be sealed with Package Such as sealed boxes, sealed bags of food, or food nutrients will be washed away by water, making food taste worse.
With water thawing method should pay attention to three points: First, do not completely freeze thawing raw food, when thawed to be able to cut with a knife when you can cook; two can not thaw too far, such as meat, fish and other food all there will be a lot of bloody water thawing out. After cooking for frozen cooked products after, when thawed can be used in heating thaw method. But the thaw must pay attention to add a small amount of heated water and low heat slowly, and not be too hasty, to prevent the use of fire caused by thaw in the cold outside the rotten phenomenon.
3. Microwave thawing method. Microwave ovens have become known for home appliances, and soon will become the company, especially the small, scattered units of cooking appliances. In addition to the main microwave cooking, food, the food is also a microwave thawing of "strength." It is the use of electromagnetic waves to freeze foods with a high rate of polar molecules rotate between the use of molecular vibration, friction, collision theory to generate a lot of heat, so that frozen food to the tables at the same heat from the inside, which fast shortening on thawing time.
