Homemade preparations were always welcomed by the hostesses. To this day, they are an indispensable attribute not only on the festive table, but also ideal for a casual dinner.
Despite the variety of canned foods on the shelves of supermarkets, self-made pickles do not leave anyone indifferent. Home preservation has not only an excellent taste, but also is rich in vitamins that are so necessary for a person.
There are many recipes for preparing various canned foods. During the cold months, berries and mushrooms collected in the summer months are to their liking. But their magnificent taste will be possible to enjoy only subject to certain rules, the implementation of which is a necessity for all types of conservation.
Beginning housewives must first get acquainted with a variety of ways and some nuances, so that even making minor mistakes, know what to do if a can of mushrooms is swollen, if mold appears or the color of a product changes.
Basic Rules
Forbidden:
- Finding canned foods in warm places. A sufficiently high temperature stimulates various chemical processes.
- Storage on a non-insulated balcony. When freezing, the volume in the jars increases, from which the glass containers may crack. Jam or jam in the frost quickly sugared.
- Too long storage. Over time, slow chemical processes will begin to occur that will affect the quality of the products.
Recommendations:
- Store no more than two years.
- Adhere to the desired temperature from 0 to + 15 ° C.
- Use only sterilized dishes.
- Rinse all products thoroughly.
Mushroom harvesting
Special attention should be paid to harvesting mushrooms for the winter. With proper preparation, they can be stored as long as possible and will be a great addition to dinner.
Before clogging, sterilized jars that are closed with lids should be sterilized. In water heated to 40 degrees, they are sterilized for about 40-50 minutes. If the water has time to boil over this time, then it is necessary to add boiling water, otherwise the glass jar will burst due to the temperature difference. Then it should immediately clog, check the quality and then cool at room temperature.
If the rules are not fully respected, then this will lead to spoilage of canned food, and you will have to face a frequent problem with all the housewives, who subsequently do not know what to do if the jar of mushrooms is swollen or the lid completely leaves.
Canning Errors
The most common mistake is insufficient sterilization, which subsequently contributes to the development of microbes in the product. As a result, over time, gas begins to be released, the presence of which leads to an increase in pressure in the container.
Another factor affecting the swelling of the lid is its quality. Air may enter the docking area with the can, which is why swelling should also be expected.
And if the lid on the jar with mushrooms still swollen during storage, further storage of the product is not recommended, since this indicates poor quality of the contents. Typically, this phenomenon can be observed within a few days after sterilization.
What to do if a jar of mushrooms is swollen?
The possibility of using defective canned food should be decided individually, depending on what product is contained in the container. If some vegetables or jam can be used after bloating, using additional processing, then mushrooms are not recommended in most cases.
This product can be re-preserved only when the mushrooms in the jar have stood for only a few hours. With this option, canned food will be uniquely safe.
How to check for botulism?
If, after all, such a nuisance happened and the marriage takes place, then you need to know what to do and what to do if the jar of mushrooms is swollen. Before subjecting the product to reprocessing, it is necessary to determine the formation of botulism. Press the swollen cover. If it misses, then a new washing and digestion of mushrooms is allowed, and if the lid does not miss, then the botulism process definitely began in the bank, and in this case it is necessary to discard all the contents. This product will not be suitable for use.
But it should be remembered that mushrooms are such a product, the use of which requires special care.
