Economic aspects Industrially produced canned tomatoes are an important product and subject to regular market analysis as well as trade considerations.
Home preservation Home canned tomatoes may be prepared in a number of ways. However, safety measures need to be taken since improperly canned tomatoes can cause botulism poisoning, whether produced industrially or at home.
Diced tomatoes Diced tomatoes usually refers to tomatoes that have been diced. In the United States retail environment, however, the term refers to canned chunks of plum tomatoes in tomato juice or tomato purée, sometimes seasoned with basil or garlic. This product is a relatively recent arrival in the processed tomato market, and has become quite popular since its introduction in the mid-90s, probably due to American tastes for a chunkier tomato sauce. Calcium chloride is sometimes added to stabilize the cell structure of the canned tomatoes, giving the end product a firmer texture.
