Why should the two ends of ham sausage be sealed with aluminum rings?

A protective film of alumina is formed on the surface of the aluminium product, which is used to separate the food and usually does not release harmful substances。However, it is not suitable for acidic and alkaline foods.

For long-term storage of Japanese sake (the inner layer of aluminum canned beverages is covered with a film), do not wash it with steel wool balls! At the same time, it also prevents air leakage from reacting with the air, causing odor changes and other phenomena.

First, he wanted to make him in the shape of a intestine instead of a flat package. The packaging has a certain heat shrinkage and looks prettier, so there aren't many sealing options. Secondly,Aluminum itself is notRare metalsThe annual domestic output is close to 40 million tons

Finally, despite the fact that you think it's wasted on aluminumHam sausageThe packaging is called a casing. The material is made of PVDC composite. This should be the best preservation technique that currently exists.

PVDC has been used in foreign countries as a substitutePolyethyleneAsplastic wrap

At present, the domestic level is still at the PE level. He kept the information on it. The surface of aluminum is oxidized in the air to form a relatively stable dense oxide film.

In addition, it is relatively lightweight. Aluminum is an easy ** metal, whichRateHigher than steel。It can achieve good circulation and prevent waste.

If you switch to plastic products, the first is that the strength is not enough, and the second is that it is not (meaningless) and difficult to degrade, which will cause more serious pollution.

Aluminium elementsIt is compact, light in texture, and beautiful in color, so it is often used as a packaging material, especially for flavors and fragrances that emit substances with a long cycle. Therefore, we often see that most of the substances with flavors are made of aluminum foil.

The packaging is on the outside, mainly because the aluminum foil is compact and the fragrance will not volatilize in a short time, but when used as food packaging, the direct contact surface with the food is not easy to become aluminum foil because it will cause passivation.

This is done to seal and keep the ham sausage.

The freshness, as well as the taste.

It is possible to use aluminum ring seals to be stronger and less prone to deterioration, which can improve the shelf life.

Because if the ham sausage leaks, the inside of it will deteriorate.

Because it's stronger to say crazy like this, that's why it's like this.

Because the surface of aluminum is oxidized in the air to form a dense oxide film, it is relatively stable; In addition, it is lighter than the belt late, and the source stove is easy to use! This is chemical hail pretending knowledge....Hehe.

What if you can't sell it at once, what if the iron rusts, do you buy it, hehehe, there is a dense oxide film on the surface of the aluminum ......

Prevents air leakage from reacting with air and causing odor change.

A protective film of alumina is formed on the surface of aluminium products to separate the food, and usually does not release harmful substances.

However, it is not suitable to hold acidic alkaline food and alcohol for a long time (the inner layer of aluminum canned beverages is covered with a film), and do not use steel wool balls to clean!

Probably aluminum has good ductility.

I thought aluminum was soft·· If only something else might not work.

Aluminum is a metal object that absorbs heat quickly and dissipates heat quickly.

We have machines that can be separated, and several processes are needed, one is to crush and separate, the other is sorting, and the third is fine separation.

If you burn plastic, it doesn't seem to be environmentally friendly if you burn it too much.

It doesn't matter, as long as the child is not abnormal.

There should be no problem, because this one is still relatively smooth and will not hurt the stomach, so be careful in the future.

It is necessary to use food-grade lubricants so that the quality is *** Like Mobil, Shell, and Jiamei, these have food-grade lubricants.

In this case, you can take a toothpick and cut it in the middle of the ham sausage and then open it, or you can use scissors.

Take the scissors directly, and then just take the same mouth.

It doesn't matter.

There won't be a problem. Rest assured.

The question of why there is such a ham sausage every few days.
