Many people tend to wrap the ingredients they buy in cold storage, such as: when cold storage, most people may use the insulated film, but do you know? Using aluminum foil paper not only replaces the fresh film, but also has many advantages.
What are the advantages of using aluminum foil paper to store?
According to the Japanese Grape website, there are several advantages to using aluminium foil paper to preserve cold-fried meat:
1. Accelerate the speed of cold-fried and unwoven.
2. Effectively prevent cold-fried burns.
The reason for accelerating the cooling and dissolving speed is the high heat conductivity of aluminum foil paper. When cold, the temperature of meat wrapped in aluminium foil drops faster than that of the fresh film; when uncooked, the temperature rises faster.
As for the effect of preventing cold burning, it is due to the high shielding properties of the aluminum foil paper; shielding properties refer to its characteristics that are difficult to permeate oxygen, water vapor and other gases.
Tips to prevent cold-fried burning
Cold-fried burning refers to the phenomenon that the surface of food preserved by cold-fried changes in color or quality due to dryness. The main causes of cold-frying burning include:
1. Water evaporation in food
The moisture on the food surface is lost in the cold-frying warehouse (solidity directly changes to atmosphere), resulting in dryness on the surface and showing a "burning" appearance. If the moisture evaporates continuously, the surface of the cold food may have a dry texture or white spots.
2. Oxidation and the air in the cold storage surface is connected to the surface of the food. Even if the temperature is low, it may cause oxidation due to oxygen, resulting in changes in color and flavor. Especially meat and fish, fat will deteriorate due to oxidation, further affecting the flavor.
3. Incorrect storage method
If the food is not fully sealed, cold burning will be more likely to occur when it is in contact with the air.
Based on the above reasons, the main causes of cold soaking are water evaporation and oxidation. If the bag is not sealed strictly, the air will easily enter, and the cold blasting will become more severe. Some people may think that aluminium foil paper cannot wrap food tightly, but through correct wrapping methods, the sealing can be greatly improved. For example, when cold meat, first fold the aluminium foil paper and paste the meat, then fold three sides to achieve a good sealing effect. This can effectively prevent moisture evaporation and oxidation. This wrapping method is called "U-shaped wrapping method" because it looks like "U-shaped wrapping method", which is a recommended way to improve sealing.
What should I pay attention to when solving the problem?
It should be noted that aluminium foil paper cannot be used for microwave furnaces, so if you use microwave furnace to heat, please remove the aluminium foil paper first. In addition, avoid placing the cold meat at normal temperature to degreasing, as this may lead to proliferation of food poisoning.
