The definition of canned food: refers to food that is packaged in airtight containers, commercially sterilized before or after packaging, and can be stored at room temperature for a long time. It is called canned food.

Can sealing is one of the important means of long-term storage of food. Can sealing can block the circulation of air and water inside and outside the can, prevent microorganisms outside the can from penetrating into the can, and kill spoilage bacteria in the original can, so it can Prevent deterioration and deterioration and resist long-term storage. If the seal is incomplete, all operations such as conditioning, sterilization, and packaging will be meaningless. Therefore, sealing is one of the most important basic operations in the canned food manufacturing process.

Before buying canned cats, remember these three steps: look, touch, and listen

1. Look

2. Touch

Gently touch the top cover of the can with your hand to see if there is a slight bulge like the bottle cap to confirm that the can has not expanded. There is a possibility of microbial contamination in expansion tanks or pop-up tanks.

3. Listen

Gently press the upper and lower lids with your fingers, shake the can slightly, and listen to see if there is any sound. Turn the can over to see if any liquid is exposed and make sure it is completely sealed.

2. Do not refrigerate uneaten canned food

If there are uneaten cans, replace the container immediately (any non-metallic material is acceptable) and keep it in the refrigerator for no more than three days.

Why change the container

Pet cans are usually made of tinplate cans, and the packaging material cost of aluminum cans is relatively high. Tinplate is a packaging material made of tin-plated mild steel plate on both sides. It is a kind of metal material. When opened, the iron in the can may be oxidized and released onto the food inside the can. After the can is opened, it is no longer the original sterile environment.
