Tomato puree, a staple in kitchens worldwide, provides a rich tomato flavor and thickening power to countless dishes. While homemade versions offer a certain rustic charm, the convenience of store-bought tomato puree is undeniable. But what exactly is store-bought tomato puree, and how does it differ from other tomato products? This comprehensive guide will delve into the intricacies of this versatile ingredient, exploring its composition, manufacturing process, uses, nutritional value, and more.
Understanding Tomato Puree
At its core, tomato puree is a simple product: cooked tomatoes that have been strained to remove seeds and skins, resulting in a smooth, concentrated liquid. However, the nuances in processing and added ingredients can significantly impact the final product. Store-bought tomato puree aims for consistency in flavor and texture, a crucial factor for home cooks and professional chefs alike.
The Basic Definition
Tomato puree consists of cooked and strained tomatoes, typically with a consistency thicker than tomato sauce but thinner than tomato paste. The straining process eliminates the solids, leaving behind a smooth, even base.
Distinguishing Puree from Other Tomato Products
Confusion often arises between tomato puree, tomato sauce, and tomato paste. While all three originate from tomatoes, their processing methods and final consistencies differ significantly.
Tomato sauce typically contains additional ingredients such as herbs, spices, and sometimes even vegetables like onions and garlic. It’s usually ready to use as is.
Tomato paste is the most concentrated of the three. It’s made by cooking tomatoes for an extended period, reducing the liquid content dramatically. This results in a very thick, intensely flavored paste.
Tomato puree falls in between. It is more concentrated than tomato sauce but less so than tomato paste, offering a balance of flavor and thickness.
The Manufacturing Process of Store-Bought Tomato Puree
The journey from fresh tomatoes to a neatly packaged jar or can of puree involves a carefully controlled manufacturing process. This process ensures consistent quality, safety, and shelf stability.
Tomato Selection and Preparation
The process begins with selecting ripe, high-quality tomatoes. Varieties chosen for puree production are often those known for their rich flavor and meaty texture. Once selected, the tomatoes are thoroughly washed and sorted to remove any damaged or unsuitable fruit.
Cooking and Straining
The washed tomatoes are then cooked. This cooking process softens the tomatoes and begins to develop their characteristic flavor. After cooking, the tomatoes are passed through a strainer or pulper. This machine separates the skin, seeds, and any remaining solids from the pulp, leaving behind a smooth, liquid base.
Concentration and Pasteurization
To achieve the desired consistency and flavor concentration, the strained tomato pulp is often further cooked. This cooking process reduces the water content, thickening the puree.
The final step is pasteurization, a heat treatment that destroys any harmful microorganisms and extends the shelf life of the product. The puree is heated to a specific temperature for a set period, then quickly cooled before being packaged.
Packaging and Quality Control
The pasteurized tomato puree is then filled into sterilized jars, cans, or aseptic packaging. Quality control measures are implemented throughout the entire process, from tomato selection to packaging, to ensure the product meets the required standards for safety, taste, and appearance.
Ingredients in Store-Bought Tomato Puree
While the core ingredient remains tomatoes, store-bought puree may contain other ingredients that affect its flavor, texture, and shelf life.
Main Ingredient: Tomatoes
The star of the show is, of course, tomatoes. Different varieties of tomatoes can yield purees with varying degrees of sweetness, acidity, and overall flavor intensity. San Marzano tomatoes are often lauded for their superior flavor and are sometimes used in premium purees.
Common Additives
Some manufacturers add salt to enhance the flavor and act as a preservative. Citric acid, a natural acid found in citrus fruits, is sometimes added to adjust the acidity level, helping to preserve the color and prevent spoilage. In rare cases, sugar might be added to balance the acidity, particularly if the tomatoes used are naturally tart.
Reading the Label
Always carefully read the ingredient list on the packaging. Look for purees with minimal added ingredients. Ideally, the list should only include tomatoes, salt, and possibly citric acid. Avoid products with artificial flavors, colors, or excessive amounts of sugar or sodium.
Uses of Tomato Puree in Cooking
Tomato puree’s versatility makes it an essential ingredient in a wide array of dishes, providing flavor, moisture, and thickening properties.
Base for Sauces
Tomato puree is an excellent base for various sauces, from simple pasta sauces to complex stews and braises. It can be customized with herbs, spices, and other ingredients to create a wide range of flavor profiles.
Soups and Stews
Adding tomato puree to soups and stews enriches the flavor and adds body. It blends seamlessly with other ingredients, creating a cohesive and satisfying dish.
Casseroles and Baked Dishes
Tomato puree can be used in casseroles and baked dishes to provide moisture and a subtle tomato flavor. It helps to bind ingredients together and prevent the dish from drying out.
Pizza Sauce
While some prefer a chunkier sauce, tomato puree can be a great base for pizza sauce, especially when enhanced with oregano, basil, and garlic.
Global Cuisine
Beyond traditional Italian dishes, tomato puree finds its place in cuisines worldwide. It is used in Indian curries, Mexican salsas, and many other dishes to add depth and complexity.
Nutritional Value of Tomato Puree
Tomato puree is more than just a flavorful ingredient; it also offers several nutritional benefits.
Vitamins and Minerals
Tomatoes are a good source of vitamins, particularly vitamin C and vitamin K. They also contain minerals like potassium and folate. These nutrients contribute to overall health and well-being.
Lycopene: A Powerful Antioxidant

Low in Calories and Fat
Tomato puree is naturally low in calories and fat, making it a healthy addition to your diet. It can add flavor and nutrients to dishes without significantly increasing the calorie count.
Choosing the Right Store-Bought Tomato Puree
With so many options available, selecting the right store-bought tomato puree can feel overwhelming. Here are some factors to consider.
Consider the Ingredients
As mentioned earlier, prioritize purees with minimal added ingredients. Look for those that contain only tomatoes, salt, and possibly citric acid.
Acidity Level
Some people are sensitive to the acidity of tomatoes. If you find that tomato products often cause heartburn or indigestion, look for brands that specifically mention a lower acidity level.
Packaging Type
Tomato puree is available in jars, cans, and aseptic cartons. Each packaging type has its pros and cons. Jars are reusable and allow you to see the product before purchasing. Cans are generally more affordable but can sometimes have a metallic taste. Aseptic cartons are lightweight and convenient, but they may not be as environmentally friendly as glass jars.
Organic vs. Non-Organic
If you prefer organic products, look for certified organic tomato puree. Organic tomatoes are grown without the use of synthetic pesticides or fertilizers.
Price Point
