The Core Ingredients in Great Value Diced Tomatoes
When you purchase a can of Great Value diced tomatoes, the ingredient list is intentionally short and straightforward. The main components are the cut tomatoes themselves, which are typically picked and canned at the peak of freshness in California's Central Valley. They are then packed in a liquid medium, usually their own tomato juice, to preserve their flavor and moisture. Beyond these primary ingredients, a standard can will contain a few additional components that serve specific functional purposes. Some varieties include salt for enhanced flavor, while others are specifically labeled as "no salt added".
The Roles of Calcium Chloride and Citric Acid
Two ingredients that might seem less familiar to the average home cook are calcium chloride and citric acid. They are standard additions in the canned tomato industry and serve important roles:
- Calcium Chloride (CaCl₂) : This is used as a firming agent. When tomatoes are diced, the increased surface area can cause them to become mushy during the canning process and subsequent cooking. The calcium ions in calcium chloride bind with the pectin in the tomato's cell walls, reinforcing their structure and helping the diced pieces hold their shape. This is why diced tomatoes will not break down into a smooth sauce as easily as whole canned tomatoes.
- Citric Acid: This organic acid is added to increase the overall acidity of the product. Tomatoes can have variable acidity levels, and some modern varieties may not be naturally acidic enough for safe canning. The addition of citric acid ensures a low pH, creating an unsuitable environment for the growth of Clostridium botulinum, the bacteria that causes botulism. It is a critical food safety step mandated by the USDA for home canning and widely used in commercial processing.
Ingredient Variations Across Great Value Diced Tomato Products
Walmart's Great Value line offers several types of diced tomatoes, each with a slightly different ingredient profile to suit various culinary needs. Understanding these differences can help you choose the right can for your recipe.
- Great Value Diced Tomatoes (Standard): As noted, this typically includes tomatoes, tomato juice, salt, calcium chloride, and citric acid.
- Great Value Petite Diced Tomatoes: The ingredient list is very similar to the standard version but with smaller pieces. Varieties with salt will list it, while 'no salt added' versions omit it.
- Great Value No Salt Added Diced Tomatoes: This version is for those monitoring their sodium intake. It includes cut tomatoes, tomato juice, calcium chloride, and citric acid, but specifically excludes added salt.
- Great Value Fire Roasted Diced Tomatoes: This specialty product has additional ingredients to impart a smoky flavor. While the core list remains the same, it may include spices and natural flavorings.
- Great Value Diced Tomatoes with Green Chilies: For a zesty, Southwestern flavor, this variety adds chopped green chili peppers, distilled vinegar, and other spices to the base tomato recipe.

Potential Impact on Cooking
Understanding the ingredients, particularly calcium chloride, is important for cooking. The firming agent means that Great Value diced tomatoes will hold their shape, even after long simmering times. This is a desired trait for certain dishes like a hearty chili or a chunky stew. However, if your goal is a smooth, velvety pasta sauce where the tomatoes should completely break down, you may achieve better results by choosing whole peeled canned tomatoes, which typically contain less or no calcium chloride. The added citric acid also contributes a slight tartness, which is generally well-balanced by the tomato's natural sweetness and any other ingredients in a recipe.
Conclusion
Ultimately, the ingredients in Great Value diced tomatoes are a straightforward combination of tomatoes and functional food additives designed to ensure safety and maintain quality. The use of calcium chloride for firmness and citric acid for acidity are standard industry practices. While the basic list is simple, the brand offers variations with and without salt, as well as with additional flavorings like green chilies or smoke, allowing for a range of cooking applications. By checking the specific product label, you can select the perfect can for your next recipe, whether you need a firm, chunky texture or a low-sodium option.
