Cans of tomato sauce – a staple in many kitchens around the world, particularly in Italian cuisine. But have you ever stopped to think about what exactly goes into those humble cans, or the rich history behind this beloved condiment? In this article, we’ll delve into the world of canned tomato sauce, exploring its origins, production process, nutritional benefits, and culinary uses.
Origins of Canned Tomato Sauce
Tomato sauce, in its various forms, has been a cornerstone of Italian cooking for centuries. The use of tomatoes, introduced to Europe from the New World, revolutionized Italian cuisine in the 18th century. Initially believed to be poisonous, tomatoes eventually gained popularity, and by the 19th century, tomato sauce had become a staple condiment.
The concept of canning food dates back to the early 19th century, when French chef Nicolas Appert developed a method for preserving food in glass jars. However, it wasn’t until the 1920s that canning technology improved, making it possible to mass-produce canned goods. Canned tomato sauce, in particular, became a hit in the United States during World War II, as it provided a convenient and shelf-stable alternative to fresh tomatoes for the military and civilians alike.
The Production Process
So, what goes into those cans of tomato sauce? The production process involves several steps:
Tomato Selection and Preparation
Tomatoes are carefully selected based on variety, ripeness, and quality. They’re then washed, sorted, and crushed or diced to release their natural juices and pulp.
Cooking and Concentration
The tomato puree is then cooked with onions, garlic, salt, and sometimes sugar to enhance flavor and texture. The mixture is concentrated through evaporation or vacuum evaporation to create a thick, rich sauce.
Acidification and Packaging
Citric acid or vinegar is added to the sauce to ensure a safe pH level for canning. The sauce is then filled into sterilized cans, sealed, and heat-treated to kill off any bacteria and extend shelf life.

What is the origin of canned tomato sauce in Italian cuisine?
Canned tomato sauce has a long history that dates back to the late 19th century in Naples, Italy. During this time, tomatoes were a staple ingredient in Neapolitan cooking, and canning was a way to preserve the fruit for year-round use. The first cans of tomato sauce were made by hand, with tomatoes being cooked down and packed into glass jars or metal cans.
The concept of canning tomatoes quickly spread throughout Italy, and soon, canned tomato sauce became a staple ingredient in many Italian households. The convenience and long shelf life of canned tomato sauce made it an essential component of Italian cooking, particularly for sauces, soups, and braises.
What are the different types of canned tomato sauce available?
There are several types of canned tomato sauce available, each with its own unique characteristics and uses. Crushed tomatoes are perhaps the most versatile, consisting of fully ripe tomatoes that have been crushed and packed into cans. They are great for making sauces, soups, and stews.
Other types of canned tomato sauce include diced tomatoes, which are perfect for adding texture to dishes, and tomato puree, which is a concentrated form of tomatoes often used as a base for sauces. San Marzano tomatoes are also a popular variety, known for their sweet-tart flavor and low acidity. They are often used in Neapolitan-style pizzas and pasta dishes.
How do I choose the best canned tomato sauce for my recipe?
When choosing a canned tomato sauce, there are several factors to consider. Look for cans that are labeled “san marzano” or “pomodoro” for high-quality tomatoes. Check the ingredient list to ensure that the sauce doesn’t contain added salt, sugar, or preservatives.
It’s also important to consider the acidity level of the tomatoes, as this can affect the flavor of your final dish. If you’re looking for a more balanced flavor, opt for a sauce with a lower acidity level. Finally, consider the texture and consistency of the sauce, and choose one that suits your recipe.
Can I use fresh tomatoes instead of canned?
While fresh tomatoes can be used in place of canned, they have a higher water content and may not provide the same rich, intense flavor as canned tomatoes. Fresh tomatoes are also more perishable and may not be available year-round, making canned tomatoes a more convenient option.
That being said, if you have access to ripe, flavorful fresh tomatoes, they can be a great addition to many dishes. Simply core and chop the tomatoes, then cook them down to remove excess moisture before using them in your recipe.
How do I store canned tomato sauce?
Canned tomato sauce should be stored in a cool, dry place, away from direct sunlight and moisture. Once opened, canned tomato sauce should be refrigerated and used within a few days. It’s also a good idea to transfer the sauce to an airtight container to prevent spoilage.
If you don’t plan on using the entire can, consider freezing the remaining sauce for later use. Simply transfer the sauce to an airtight container or freezer bag, label it, and store it in the freezer for up to 6 months.
Are there any health benefits to using canned tomato sauce?
Canned tomato sauce is a rich source of several important nutrients, including vitamin C, potassium, and lycopene, an antioxidant that has been linked to several health benefits. Lycopene has been shown to reduce the risk of heart disease, certain cancers, and even osteoporosis.
In addition, canned tomato sauce is low in calories and fat, making it a healthy addition to a variety of dishes. When choosing a canned tomato sauce, look for ones that are labeled “low sodium” or “no added salt” to reduce your overall sodium intake.
Can I make my own canned tomato sauce at home?
Yes, you can make your own canned tomato sauce at home, although it does require some special equipment and techniques. You’ll need a large pot for canning, as well as jars, lids, and rings specifically designed for canning.
To make your own canned tomato sauce, start by cooking down fresh tomatoes with onions, garlic, and herbs. Then, pack the sauce into hot, sterilized jars, leaving about 1/2 inch of headspace. Process the jars in a boiling water bath for 20-30 minutes to ensure that the sauce is properly sterilized and sealed.
