like in a store bought bolognaise sauce, how does the meat in it stay safe to eat? the ones where it has the part on the lid that u press to check it hasn’t been unsealed.
i love meat sauces but genuinely just curious about what happens to it that makes it able to be kept in a jar out of the fridge for months and it still being safe to eat?

Part of canning food is making sure all of the bacteria is dead before sealing it up. That usually means boiling the jars and lids, pouring sauce in while it’s still hot.
That’s the reason why a can or jar that isn’t fully sealed should be discarded – on glass jars you have the center of the lid that pops up to let you know it’s not sealed anymore. That piece of the lid gets pulled down as the contents cool. On metal cans you just have to look for holes.
If they aren’t sealed, there’s a good chance bacteria got in and ruined your food.
