Where to store

Canned corn in glass jars is stored no more than 3 years. But the store product in cans no more than 2 years. This is due to the fact that due to the metal content is oxidized faster and its shelf life is reduced. Such preservation is stored in a dark dry place at room temperature of 22-25 ° C.

For storage is well suited cellar, storage room or just a shelf in the kitchen. After opening the lid and using the corn completely, the jar with it is placed on the shelf of the refrigerator and stored for no more than a day. At the same time, it is better not to drain the pickle, because without it the corn kernels are stored less and lose their taste qualities faster.

Why can lid swell

When opening corn, it is very important to turn on the lid; if it is swollen, then there is a chance that the product has deteriorated and may cause poisoning.

The reasons for swelling of the lid or damage to such preservation may be as follows:

  • storage of canned corn at high temperature (above 25 ° C), especially in the summer heat. In this case, harmful and dangerous microorganisms have not yet formed, but certain chemical processes have led to the lid swelling. And yet in this case it is better not to risk and refuse to eat such a product;
  • violation of cooking technology;
  • a hermetically rolled up jar - this happens when an unsuccessful roll-in or when the jar lid does not fit
  • lack of sterility of the container, if the jars and lids were poorly sterilized;
  • substandard products. This happens when the vegetables were poorly washed or rotten;
  • corn cans tend to "explode." This is due to the high content of proteins and the almost complete absence of acids. In order to eliminate this problem during conservation, it is recommended to add a little vinegar, lemon juice or citric acid. To eliminate this trouble, you can not apply acid, but simply sterilize the jars with this product for at least two or three hours.

Important! Sterilization of cans is recommended to be carried out several times (2-3 times), since after one sterilization spore microorganisms may not completely die.
