Jars can be very useful for storing food in your kitchen. They don’t take up much space and add an aesthetic touch to your pantry. But for proper storage of your food, it is important to follow the rules for storing food in jars.
Although they can be stored for a very long time, the preserves in the jars have an expiry date. In general, canned jars can be kept for a year but they can spoil if improperly stored.
Depending on the foods you store in the jars, you need to pay attention to how they are stored. In fact, depending on their acidity level, they must be stored differently in order to to prevent the proliferation of bacteria harmful to health. In order for your jars to last as long as possible, you must sterilize them well so that they properly preserve the food you are going to place inside. But sometimes it happens that your jars are not properly disinfected and your food becoming spoiled without you realizing it. To avoid food poisoning, here’s how to know whether the food in your canned jars is still edible.
If the lid of your jars is domed, your food is probably spoiled
Food from a jar is no longer edible if you find the lid of your jar completely domed. Also, if you see foam or the food give off a bad smell, it means that they are spoiled and you can no longer consume them. In this case, throw away your jar directly and do not try to consume the food inside. If your jar has a loose lid, throw it away as well because a botulism-causing toxin may be present in your food; she does not changes the color, taste or smell of food. Finally, wash your hands and all the surfaces of your kitchen as well as your equipment to avoid food poisoning.
To ensure that your storage jars last a long time, proper sterilization is a must. To do this, boil the glass jars for 5 to 10 minutes, then put them upside down to dry before filling them with food to be preserved and putting them again in boiling water. Bring the food to 100° so that it is perfectly sterile.
How long should store-bought jars be kept?
Canned jars are offered with expiry dates according to very specific hygiene rules and standards depending on the country. But these dates can be exceeded without risk of food poisoning. On the other hand, if the jar has swollen, this means that the food has begun to ferment and is rotting. Do not attempt to cook the food and discard the jar.
