Tomato paste is a fundamental ingredient in many cuisines around the world, particularly in Mediterranean, Italian, and Middle Eastern cooking. It is made by cooking tomatoes down to a thick, concentrated paste, which is then used to add depth and richness to a variety of dishes, from sauces and soups to stews and braises. One of the key characteristics of tomato paste is its concentration, which can vary depending on the manufacturing process and the intended use of the product. In this article, we will delve into the world of tomato paste concentration, exploring what it means, how it is measured, and why it matters in cooking.
What is Tomato Paste Concentration?
Tomato paste concentration refers to the amount of solid tomato material present in the paste. It is typically expressed as a percentage, with higher percentages indicating a more concentrated product. The concentration of tomato paste is important because it affects the flavor, texture, and overall performance of the paste in cooking. A more concentrated paste will have a more intense flavor and a thicker consistency, while a less concentrated paste will be milder and more prone to separation.
Measuring Tomato Paste Concentration
The concentration of tomato paste is typically measured using a device called a refractometer. A refractometer measures the refractive index of a solution, which is the degree to which it bends light. In the case of tomato paste, the refractive index is directly related to the concentration of solids. By measuring the refractive index of the paste, manufacturers can determine its concentration and ensure that it meets their quality standards.
Refractometer Measurement Process
The process of measuring tomato paste concentration using a refractometer is relatively straightforward. A small sample of the paste is placed on the refractometer, and the device is calibrated to read the refractive index. The refractive index is then converted to a concentration value using a pre-determined scale. This scale is typically based on the Brix scale, which is a standard unit of measurement for the concentration of sugars and other soluble solids in foods.
Types of Tomato Paste Concentration
Tomato paste is available in a range of concentrations, each with its own unique characteristics and uses. The most common concentrations are:
Tomato paste with a concentration of 18-20% is considered low-concentration and is often used in sauces and soups where a mild tomato flavor is desired. Tomato paste with a concentration of 22-24% is considered medium-concentration and is a good all-purpose choice for many recipes. Tomato paste with a concentration of 28-30% is considered high-concentration and is often used in recipes where a intense tomato flavor is desired, such as in braises and stews.
Factors Affecting Tomato Paste Concentration
Several factors can affect the concentration of tomato paste, including the type of tomatoes used, the cooking time and temperature, and the amount of water added during processing. Tomato variety is a key factor, as some varieties are naturally more concentrated than others. Cooking time and temperature also play a role, as longer cooking times and higher temperatures can result in a more concentrated paste. Water addition is another important factor, as adding too much water can dilute the paste and reduce its concentration.
Impact of Concentration on Flavor and Texture
The concentration of tomato paste has a significant impact on its flavor and texture. A more concentrated paste will have a more intense, richer flavor and a thicker, more velvety texture. This makes it ideal for recipes where a strong tomato flavor is desired, such as in pasta sauces and braises. A less concentrated paste, on the other hand, will have a milder flavor and a thinner consistency, making it better suited for recipes where a subtle tomato flavor is desired, such as in soups and stews.

What is tomato paste and how is it made?
Tomato paste is a concentrated form of tomatoes that has been cooked down to remove excess water, resulting in a thick, rich paste. The process of making tomato paste involves several steps, starting with the selection of fresh, ripe tomatoes. These tomatoes are then washed, sorted, and chopped before being cooked in large vats to break down the cell walls and release the natural juices. The cooking process is typically done under vacuum or at high temperatures to preserve the flavor and nutrients of the tomatoes.
The cooked tomatoes are then strained or pureed to remove any seeds, skin, or excess pulp, resulting in a smooth, consistent paste. The paste is then further concentrated through evaporation or other methods to achieve the desired consistency and flavor. Tomato paste can be made from a variety of tomato types, including plum, cherry, and beefsteak tomatoes, each with its own unique flavor profile and characteristics. The final product is a versatile ingredient that can be used in a wide range of dishes, from sauces and soups to stews and braises, adding depth, richness, and a burst of tomato flavor.
What are the different concentrations of tomato paste available?
Tomato paste is available in various concentrations, which are typically measured by the percentage of solids present in the paste. The most common concentrations are single, double, and triple concentrate, with single concentrate being the most diluted and triple concentrate being the most concentrated. Single concentrate tomato paste typically has a solids content of around 12-15%, while double concentrate has a solids content of around 24-28%, and triple concentrate has a solids content of around 36-40%. The choice of concentration depends on the intended use of the tomato paste, with more concentrated pastes being better suited for dishes where a strong tomato flavor is desired.
The concentration of tomato paste can also affect its texture and consistency, with more concentrated pastes being thicker and more gel-like.
