Follow the picture tutorial or find the printable card at the end of the post. As soon as they are chopped or crushed, enzymes start to break down the pectin that helps to hold tomato cells together. The enzyme that causes separation is activated by exposure to air and inactivated by heat. In commercial production, tomatoes are flash heated nearly to boiling in a matter of seconds, using equipment not available to consumers. Because the pectin holding tomato cells together is not exposed to air when cold, it remains intact, and a thick bodied, homogeneous juice is produced.
How to Make Canned Stewed Tomatoes
If you don't own a pressure canner, don't worry -- it is possible to can tomatoes without one. Water bath canning works too as long as you follow the instructions.

Each quart of tomatoes will need a teaspoon of salt and a tablespoon of bottled lemon juice. Coarse kosher sat works best for canning, and using bottled lemon juice is the safest way to ensure a consistent level of acidity that will keep the jars shelf-stable. Canning can be a little labor-intensive and requires some practice and specialized equipment, like a wire jar rack for the water bath, but the result is well worth it.

Make sure you keep the temperature of the freezer at 0°F or below to ensure proper freezing. Frozen tomatoes will retain their flavor for 12 months.
Start with firm, unblemished tomatoes, and wash them well in cold water. A. No, oven canning is not safe because of temperature fluctuations. Also, the jars can explode in dry heat.
Options for Pressure Canners
This gives you plenty of time to thaw them to use in your favorite sauce, stew, or soup recipes. You can eat canned tomatoes past the expiry date as long as the cans are unharmed and show no signs of bulging.
