Practical housewives prefer to make canned vegetables, fruits, and meats on their own. Home cooking is always associated with the selection of tightly closed containers.

TIPS FOR SELECTION DEPENDING ON THE TYPE OF PRESERVATION.
When determining which lids are best for canning, it is necessary to take into account not only the features of the products themselves, but also the characteristics of the product. Certain varieties are suitable for vegetables, fruits, meat, fish. The choice is governed by redox properties. To choose the right canning lids, it is recommended to consider the following tips:
1. Unlacquered, tin-plated, tin lids (white) are only suitable for products with low acidity — marmalade, jams, preserves, compote. However, if fruits and berries have a bright color, it is better to use varnished color for them.
2.Products saturated with protein (meat, legumes) should not be left under a white tin lid. Amino acids, into which protein breaks down, can enhance the oxidative process.
3. Iron jar lids with anti-oxidation varnish coating are suitable for marinades, pickles, adjika, vegetable salads. These dishes contain many organic acids, which require chemically inert surfaces.
CRITERIA FOR ASSESSING PRODUCT QUALITY
In order for ready-made canned food to retain high characteristics for a long time, it is necessary to check the quality of the lids before cooking them. They must not be deformed, broken, moldy or rusty. The edge of the products must be even, without potholes, cracks, wavy bending.
When choosing tin pieces, you need to pay attention to the rubber seal. If it is elastic and elastic, then the expiration date has not yet expired. In old products, the rubber dries out and loses its ability to spring. The sealing ring must not be twisted. If a defective element is found in already purchased covers, they must be replaced. You can find elastic bands for lids in hardware stores where seaming accessories are presented.
The optimum thickness of the tin should be 0.2 mm. Tin lids must be varnished on the inside. Also, high quality tin covers must be made in accordance with GOST.
