How to use the front and back of tin foil

by admin

carefully observe the tin foil and you can find that its two sides are different. One side is bright and the other side is dark. The bright side is called the photosensitive side, and the darker side is called the matte side. When we use it, we should use the matte side to contact the food to improve the heat conduction effect., The photosensitive surface is exposed. If you accidentally use it upside down, the photosensitive surface contacts the food, which may cause the food to adhere to the tin foil

extended data:

aluminum foil paper, also known as tinfoil in Hong Kong, is a thin sheet with a thickness of less than 0.2mm processed by aluminum foil rolling mill. Most of the aluminum foil paper is bright on one side and matte on the other side. It is mainly used for packaging food, drugs, cosmetics and other chemicals. Tin foil is processed by aluminum foil rolling mill. Generally, it is processed into a thin sheet with a thickness of less than 0.2mm. The raw material for processing is aluminum block. After processing, it is cut into the required length and width, and then rolled up, packaged and sold

some foods (such as sweet potato, golden mushroom, etc.) must be wrapped in aluminum foil to avoid burning. Wrap it in aluminum foil to cook seafood, mushrooms, vegetables, etc. to preserve the freshness

the role of tin foil when used for barbecue:

the first is to prevent food from sticking to the baking tray

the second is to prevent food from sticking to dirty things

the third is to facilitate brushing the baking tray

the fourth is that some food has seasonings and fillings when baking, which are afraid to be scattered. Wrap them with tin foil

the fifth is to prevent water loss and keep them fresh

whether the front and back sides of tin foil can be used, it is generally recommended to use bright side
most of the tinfoil is bright on one side and matte on the other. Aluminum foil paper for food can wrap food on both sides. It is recommended to wrap it with bright bread to improve the heat conduction effect
development history of tinfoil:
the original tinfoil is really made of tin. Tinfoil is softer than aluminum foil, and it will have a little tin flavor when wrapping food. At the same time, tinfoil limits its use in food packaging because of its low melting point and can not be heated, or its high heating temperature – such as embrittlement when it is above 160 ℃. For example, it needs to barbecue food, Tin foil cannot be used when baking food. Since the aluminum foil paper came into being, it began to melt when heated to above 660 ℃ due to its high melting point. It can be applied to ordinary barbecue food, baked food, and even traditional flower chicken. It is wrapped and baked with aluminum foil paper, which is clean and hygienic while maintaining the original flavor. Therefore, after the reduction of aluminum price, aluminum foil replaced tin foil in daily life. However, because aluminum will affect brain development, the surface of current aluminum foil will be coated to avoid the release of aluminum
main functions of tin foil paper:

tin foil paper is usually used to hold food (such as aluminum foil paper tray). When used for barbecue, it can wrap bean sprouts, potatoes, sweet potatoes, etc. for barbecue to prevent them from burning. Sometimes used for decoration. Modern tin foil is made of aluminum. It can also be used as aluminum electrode for electrolysis. There are also hairstylists who perm guests with tinfoil. Some people also use tinfoil to absorb the oil in the soup. Tin foil is also widely used as an isolation layer, heat exchange, and as a conductor. Usually, the thickness of aluminum foil used in paper wrapped beverage packaging and food packaging bags is only 6.5 microns. This thin aluminum layer can be waterproof, keep fresh, prevent bacteria and dirt. It is very common to use tinfoil trays to hold food. Although aluminum foil trays are disposable, they are made of aluminum and do less harm to nature

electric hair

some hairstylists wrap their hair in tinfoil to heat it, which has a good heat transfer effect. Improper use of tin foil can lead to burns, poor hair quality and other problems

oil absorption

rub the tin foil into a ball and open it to absorb the oil in the soup. The principle is that the surface tension of aluminum foil paper will be amplified in the process of wrinkling aluminum foil paper

tin foil is pressed out of aluminum block by rolling machine, then cut into the required length and width, and then rolled up, packaged and sold. Ordinary aluminum foil paper and aluminum foil paper tray can be purchased in supermarkets and
department stores, and tin foil paper can be purchased in hardware stores and industrial materials companies.

both front and back sides are the same (⊙ o ⊙), tin foil is also aluminum foil, with single-sided light and double-sided light, mainly due to different rolling processes and consistent properties. No impact.

many people are mistaken. In fact, they should wrap food with reflective surface, and the dumb surface is right outside, because it uses the reflection principle of light. The function of the outer matte surface is to absorb light energy and heat energy as much as possible, while the reflective surface of the inner layer wraps the absorbed light energy and heat energy inside to continuously form reflection, so that the food materials can be heated quickly and evenly, and at the same time, it can keep the water, nutrients and flavor of the food from losing. On the contrary, if the reflective surface is outside, it will reflect the light to the outside space, which will reduce the efficiency of light energy heating, prolong the time of processing food materials, and greatly reduce the color and flavor!
