There are different lids for canning:
- white metal;
- yellow;
- golden lids with a lacquer coating on the inside and outside.
In order for vegetables and fruits to look good and keep well, the marinade must contain a preservative (citric acid or vinegar). Therefore, it is very important that the lid has a special lacquered coating. If not, the material will oxidize.
Yellow lids for canning
For this reason, uncoated white metal lids should not be used for long-term preservation not only for vegetables and jams but also for meat and legume preparations as the protein will react with the lid material.
Sterilisation of lids
Which lids are best to use
Choose lids that have a lacquered coating on the outside and inside. This material is chemically resistant to acids and is very versatile.
How to check the lid
Laminated lids for canning with lacquer finish
If you cannot determine whether your lid is suitable for canning, moisten a cotton ball with acetone and wipe the lid from the inside. If there is a yellow or green mark on the surface, do not close the jar with such a lid.
