Canning - is a method of preserving food for a long time by packing them in sealed containers. In the form of canned food today can be consumed fruits, vegetables, beans, soups, meat, fish and seafood. Canned foods are often considered to be less nutritious than fresh or frozen their counterparts, but this is not always the case.
In fact, in some cases canning preserves the food most of the nutrients. Thus, most of the minerals and fat-soluble vitamins such as vitamins A, D, E and K, are stored in cans. However, since the process usually requires a high temperature, water-soluble vitamins of group B and C may be damaged. However, these vitamins in general are sensitive to heat and air, so they are also lost when any cooking in the kitchen.
In turn, canning allows you to increase the amount of other nutrients. For example, tomatoes and corn produce more antioxidants when heated, which makes canned kinds of products are more rich source of nutrients.
