What are the specific uses and functions of aluminum foil paper?

1. Wrap ingredients
If round ingredients such as pineapple bread and small meal buns are directly baked in the oven, the outer skin will be burnt and the inner filling will not be heated. You can wrap the ingredients with aluminum foil with the bright side facing inwards before baking, so that the ingredients can be evenly distributed inside and outside. heat.
Principle: The heat source of the oven is transmitted to the aluminum foil and then to the food, so that the airtight interlayer between the food and the aluminum foil produces water vapor and hot air, and the food can be heated more evenly.
2. Put the grinding plate
After ginger and garlic are ground into mud on the grinding plate, the residue is always stuck in the small hole of the grinding plate, which is troublesome to clean and easy to cut hands. The shiny side of the aluminum foil is smooth, put the shiny side of the aluminum foil up on the grinding board and press it together, then grind the mud, the food will not get stuck, and the aluminum foil can be reused.
Principle: The aluminum foil paper is easy to shape, put it on the grinding plate and press it flat, the raised part of the grinding plate will make the aluminum foil paper produce sharp edges and corners, which is very convenient for grinding mud.
3. Cream preservation
The unpacked cream can be wrapped in aluminum foil and then stored in the refrigerator. The fresh-keeping effect is better than that of plastic wrap. Because it is not heated, the cream can be wrapped with the shiny side inward or the matte side inward.
Principle: Aluminum foil paper has better barrier properties than plastic wrap, which can isolate most of the air, moisture and light, and can prolong the fresh-keeping period.
4. Remove stains
Any metal pan can be wiped with a ball of aluminum foil. For example, the burnt dirt on the barbecue grill, or the oven where the food has been baked, can be rolled into balls of used aluminum foil and used to scrub.
Principle: Kneaded into a spherical aluminum foil, the surface will have many edges and corners to produce scraping effect, which can be used to remove pot stains.
5. Sharp scissors
If the scissors become dull, don't rush to throw them away. You can restore the sharpness of the scissors by cutting the aluminum foil.
Principle: Just like a whetstone sharpens a kitchen knife, scissors will generate friction when cutting aluminum foil, which will make the scissors sharp.
6. Clay preservation
Paper clay, resin soil, etc. that children play with can be wrapped in aluminum foil for storage.
Principle: Aluminum foil can prevent direct light, block air, and prolong the shelf life of clay. It can be wrapped with the bright side or the matte side inward.
7. Brighten silverware
Add baking soda to the water and put the aluminum foil wrapped in silverware to restore the luster to the blackened silverware. You can wrap the shiny side inward and outward.
Principle: The aluminum in the aluminum foil and the baking soda water will produce a redox reaction, so that the blackened and foggy areas on the surface of the silverware will be restored to light.
