In the fragrance! The windows of residents in Dazhou, Sichuan Province are covered with sausages. What is the secret of keeping sausages for a long time?

Low temperature, high salinity and small contact area with oxygen. Sausages are usually made in winter. Tracing back to its origin, on the one hand, because the ancients had no better way to preserve food in the past, and on the other hand, because it was difficult for them to obtain fresher meat through hunting or other means after the cold weather, they invented this method of filling and storing meat. I have to say that the wisdom of the ancient working people is endless ~ but sausages are not bad, just compared with other meat products.

First of all, the outdoor temperature is low in winter.

Sausages are usually made after the weather turns cold. The reason why this time period is chosen is that sausages and bacon made in 1 1 month and1February just catch up with the Spring Festival of the following year, and on the other hand, because of the low temperature environment, sausages are conducive to outdoor air-drying and preservation.

Secondly, the meat injected with sausage has a high salt content.

Meat products poured into sausages are generally seasoned and pickled, and the overall salt content is relatively high. In an environment with high salt content, the production and development of various bacteria will be affected, which is the reason why pickles and salted duck eggs are preserved for a long time.

Thirdly, after sausage is filled, the contact area between meat and oxygen is small.

This is also a problem of the growth environment of bacteria. As we all know, ordinary food is moldy and spoiled by exposure to air. Microbes and fungi contained in food itself will come into contact with oxygen in the air and grow rapidly under the catalysis of oxygen, which will lead to food deterioration. However, there is a casing on the outer layer of sausage, which makes the meat products in the casing basically have no possibility of contacting oxygen, so it is very helpful for its storage time.
