Although any tomato type can be used, red paste tomatoes are the preferred tomato for canning or processing, according to the University of Illinois Extension. Meatier and containing fewer seeds than other tomato types, most red paste tomato plants ripen within a short period of time, which makes them ideal for processing large quantities. The methods used for processing tomatoes are pressure canning or boiling water bath processing. Although both processes are acceptable for tomatoes, the USDA suggests that pressure canning results in better quality and nutrition.
