The world of cooking is filled with mysteries, but one question has puzzled home cooks and professional chefs alike for years: how many plum tomatoes are in a can of diced tomatoes? It’s a question that may seem trivial at first, but understanding the answer can make a significant difference in the flavor, texture, and overall quality of your dishes. In this article, we’ll delve into the world of canned tomatoes, explore the history of plum tomatoes, and provide you with the information you need to make informed decisions in the kitchen.
Introduction to Plum Tomatoes
Plum tomatoes, also known as Roma or Italian tomatoes, are a variety of tomato that is specifically grown for canning and cooking. They are characterized by their elongated shape, dense flesh, and low water content, making them ideal for sauces, soups, and other dishes where a rich, intense tomato flavor is desired. Plum tomatoes are higher in solids and lower in water compared to other tomato varieties, which makes them perfect for cooking and canning.
History of Canned Tomatoes
The practice of canning tomatoes dates back to the early 19th century, when Napoleon Bonaparte offered a prize to anyone who could develop a method for preserving food. Nicolas Appert, a French chef and confectioner, won the prize with his technique of packing food in glass jars and sealing them with wax. Later, Peter Durand invented the tin can, and the first canned tomatoes were produced in the United States in the 1860s. Today, canned tomatoes are a staple in kitchens around the world, and plum tomatoes are the preferred variety for canning due to their unique characteristics.
Canning Process
The canning process involves several stages, including sorting, washing, chopping, cooking, and packaging. The quality of the tomatoes is crucial at every stage, as it directly affects the final product. Plum tomatoes are sorted and washed to remove any debris or impurities, then chopped into small pieces to release their natural juices. The chopped tomatoes are then cooked with salt and sometimes other ingredients like citric acid or basil, before being packaged in aseptic cans or jars.
Estimating the Number of Plum Tomatoes in a Can
To estimate the number of plum tomatoes in a can of diced tomatoes, we need to consider several factors, including the size and weight of the tomatoes, the can size, and the packing efficiency. A standard can of diced tomatoes is usually 14.5 oz (410g) or 28 oz (794g). Assuming an average weight of 2-3 oz (57-85g) per plum tomato, we can make an educated estimate.
Let’s consider a 14.5 oz (410g) can of diced tomatoes. If we assume an average weight of 2.5 oz (71g) per plum tomato, we can calculate the number of tomatoes as follows:
410g (can weight) / 71g (average tomato weight) ≈ 5.8 tomatoes
However, this calculation is highly approximate and does not take into account the packing efficiency, which can vary depending on the manufacturer and the specific product. Additionally, the weight of the tomatoes can vary significantly depending on their size, variety, and growing conditions.
Factors Affecting the Number of Tomatoes
Several factors can affect the number of plum tomatoes in a can of diced tomatoes, including:
- Tomato variety: Different varieties of plum tomatoes have varying sizes, shapes, and weights, which can impact the number of tomatoes in a can.
- Can size: Larger cans will generally contain more tomatoes than smaller cans, but the packing efficiency can also play a role.
- Packing efficiency: The way the tomatoes are packed into the can can affect the overall weight and number of tomatoes. Some manufacturers may use a more efficient packing method, resulting in more tomatoes per can.
- Moisture content: The moisture content of the tomatoes can also impact the overall weight and number of tomatoes in a can. Tomatoes with higher moisture content will weigh more, but may not necessarily result in more tomatoes per can.
Conclusion
Estimating the exact number of plum tomatoes in a can of diced tomatoes is a complex task, as it depends on various factors, including the tomato variety, can size, packing efficiency, and moisture content. However, based on our calculations, we can estimate that a 14.5 oz (410g) can of diced tomatoes may contain approximately 5-6 plum tomatoes, assuming an average weight of 2.5 oz (71g) per tomato. This estimate should be used as a rough guide, and the actual number of tomatoes may vary depending on the specific product and manufacturer.

What is the average number of plum tomatoes in a can of diced tomatoes?
The average number of plum tomatoes in a can of diced tomatoes can vary depending on the size of the can and the desired consistency of the diced tomatoes. Generally, a can of diced tomatoes can contain anywhere from 2 to 6 plum tomatoes, with the most common range being 3 to 4 tomatoes. This is because plum tomatoes are typically smaller and more oval in shape than other varieties, making them ideal for canning and dicing.
To give you a better idea, a standard 14.5-ounce can of diced tomatoes usually contains around 3 to 4 plum tomatoes, while a larger 28-ounce can may contain 5 to 6 tomatoes. However, it’s worth noting that some brands may use more or fewer tomatoes depending on their specific recipe and production process. Additionally, the number of tomatoes can also be affected by factors such as the ripeness and quality of the tomatoes, as well as the desired flavor and texture of the final product.
How are plum tomatoes selected and prepared for canning?
Plum tomatoes are typically selected for canning based on their size, shape, and quality. Tomatoes that are too small or too large may not be suitable for canning, as they may not dice evenly or may not have the desired texture. The selected tomatoes are then washed, sorted, and graded according to their size and quality. Next, they are blanched in hot water or steam to remove the skin, and then diced or crushed to the desired consistency.
The diced or crushed tomatoes are then packed into cans, along with any additional ingredients such as salt, citric acid, or other seasonings. The cans are then sealed and heated to a high temperature to kill off any bacteria and create a vacuum seal. This process, known as retorting, helps to sterilize the contents and extend the shelf life of the canned tomatoes. Once the cans have cooled, they are labeled and packaged for distribution to stores and consumers.
What factors affect the number of plum tomatoes in a can of diced tomatoes?
Several factors can affect the number of plum tomatoes in a can of diced tomatoes, including the size and variety of the tomatoes, the desired consistency and flavor of the final product, and the production process used by the manufacturer. For example, some manufacturers may use a combination of plum and other tomato varieties to achieve a specific flavor or texture. Additionally, the ripeness and quality of the tomatoes can also impact the number of tomatoes used, as riper tomatoes may be softer and more prone to breaking down during processing.
The production process itself can also influence the number of tomatoes in a can. For instance, some manufacturers may use a more efficient dicing process that allows them to use fewer tomatoes, while others may use a more traditional method that requires more tomatoes to achieve the desired consistency. Furthermore, factors such as the time of year, weather conditions, and soil quality can also impact the yield and quality of the tomatoes, which can in turn affect the number of tomatoes used in a can.
Can I use fresh plum tomatoes instead of canned diced tomatoes in a recipe?
While it is possible to use fresh plum tomatoes instead of canned diced tomatoes in a recipe, it’s not always a straightforward substitution. Fresh tomatoes have a higher water content and a more delicate texture than canned tomatoes, which can affect the flavor and consistency of the final dish. Additionally, fresh tomatoes may require more preparation time, as they need to be washed, cored, and diced before use.
That being said, using fresh plum tomatoes can be a great way to add flavor and texture to a dish, especially during the peak tomato season when fresh tomatoes are at their best. To use fresh tomatoes in place of canned diced tomatoes, you can try roasting or cooking them down to reduce the water content and intensify the flavor. You can also use a combination of fresh and canned tomatoes to achieve the desired consistency and flavor. However, keep in mind that using fresh tomatoes may require adjusting the amount of liquid and seasoning in the recipe to compensate for the differences in texture and flavor.
How do different brands and types of canned diced tomatoes vary in terms of plum tomato content?
Different brands and types of canned diced tomatoes can vary significantly in terms of plum tomato content, depending on the manufacturer’s recipe and production process. Some brands may use more plum tomatoes per can, while others may use a combination of plum and other tomato varieties. Additionally, some brands may offer organic or premium versions of canned diced tomatoes that use higher-quality tomatoes or more traditional production methods.
In terms of specific variations, some brands may offer canned diced tomatoes that are labeled as “plum tomato” or “San Marzano-style,” which may indicate a higher proportion of plum tomatoes in the can. Other brands may offer flavored or seasoned versions of canned diced tomatoes that use a blend of tomato varieties and spices. When shopping for canned diced tomatoes, it’s a good idea to check the ingredient label and look for certifications such as “USDA Organic” or “Non-GMO” to get an idea of the quality and content of the tomatoes.
Are there any health benefits to using plum tomatoes in canned diced tomatoes?
Plum tomatoes are a nutrient-rich variety of tomato that is high in vitamins, minerals, and antioxidants. They are an excellent source of lycopene, an antioxidant that has been linked to several health benefits, including reduced risk of heart disease and certain types of cancer. Plum tomatoes are also low in calories and high in fiber, making them a healthy addition to a balanced diet.
When used in canned diced tomatoes, plum tomatoes can help to retain their nutritional value due to the canning process, which helps to preserve the tomatoes’ natural antioxidants and flavor compounds. Additionally, canned diced tomatoes made with plum tomatoes can be a convenient and healthy way to add more fruits and vegetables to your diet, especially during the off-season when fresh tomatoes are not available. However, it’s worth noting that some canned diced tomatoes may contain added salt or other ingredients, so it’s always a good idea to check the label and choose a low-sodium or organic option whenever possible.
Can I grow my own plum tomatoes for canning and cooking?
Yes, you can grow your own plum tomatoes for canning and cooking, provided you have a suitable climate and growing conditions. Plum tomatoes are a popular variety for home gardeners, as they are relatively easy to grow and produce a high yield of fruit. To grow plum tomatoes, you will need to choose a variety that is well-suited to your climate and soil type, and provide the plants with full sun, well-draining soil, and regular watering.
When growing plum tomatoes for canning, it’s a good idea to choose a variety that is specifically bred for canning and cooking, such as ‘Roma’ or ‘San Marzano’. These varieties tend to have a higher solid content and a more dense texture, making them well-suited for canning and cooking. You can also try growing a combination of plum and other tomato varieties to create a unique and flavorful blend for canning and cooking. With proper care and attention, you can enjoy a bountiful harvest of fresh plum tomatoes and enjoy the satisfaction of preserving your own homegrown produce.
