The reason why jar lids bloat is due to the activity of microbes. Once in a favorable environment full of nutrients, microbes that have survived sterilization begin to multiply actively. The environment itself is favorable for them: a warm, humid environment, closed to direct sunlight are the best conditions for the multiplication of most microorganisms. During their vital activity the microbes release gases - carbon dioxide and hydrogen sulfide. It is these gases that cause the lids to swell - the pressure inside the jar rises and the thin metal of the lids is lifted. In some cases, the pressure is so strong that the lid cannot withstand it and is blown off the jar.

It's simple, vacuum presses and swells it up according to your theory.

If you convert a can to gas, you can inflate a can pretty good. And microbes do just that.

That's why they add antiseptic preservatives to keep the microorganisms from raging and releasing gas as they live.

Everything can be explained, but you don't have enough knowledge yet.

Vova, do you really not know what causes canned food to bloat? I thought you were kidding yesterday. It's very messed up.

Vova again about the powerlessness of science.
