What Is Diced Tomato Paste?

Diced tomato paste is a concentrated tomato product that combines small tomato pieces

(diced tomatoes) with thick, standardized tomato paste. It delivers both the

chunky texture of tomato dice and the rich color and flavor of tomato paste,

making it ideal for finished products that need visible tomato particles in a thick, stable base.

In industrial and foodservice contexts, diced tomato paste may also be referred to as:

• diced tomato in paste
• diced tomatoes in tomato paste
• tomato dice in concentrated tomato base
• diced tomato concentrate

Unlike simple diced tomatoes in juice, diced tomato paste products use a concentrated paste or purée

as the packing medium. This creates a dense, sauce-like matrix that is especially useful in

tomato-based sauces, dips, salsas, relishes, chutneys, and spreads.

Key Components of Diced Tomato Paste

• Diced tomato pieces – usually from peeled, ripe processing tomatoes, cut into uniform cubes.
• Tomato paste or concentrated purée – standardized to a specific brix level (soluble solids content).
• Optional salt or acidity regulators – depending on regional regulations and application needs.

Why Use Diced Tomato Paste in Sauces, Dips, and Spreads?

Food manufacturers, caterers, and brand owners choose diced tomato paste because it offers

technical, sensory, and economic advantages over using separate diced tomatoes and tomato paste.

Processing and Production of Diced Tomato Paste

Understanding how diced tomato paste is produced helps buyers and formulators select

appropriate specifications for sauces, dips, and spreads. While processes vary by facility and region,

most modern production lines follow similar stages.

1. Raw Tomato Selection

High-quality diced tomato paste relies on ripe processing tomatoes with

suitable solids content, color, and firmness. Industrial processors typically:

• Source from open-field or greenhouse-grown processing varieties.
• Target tomatoes with consistent color (deep red) and minimal defects.
• Screen incoming loads for brix, color, and foreign material.

2. Washing, Sorting, and Peeling

• Tomatoes are washed to remove soil, leaves, and foreign matter.
• Sorting systems remove under-ripe, overripe, or damaged fruit.
• Peeling is performed by steam, hot water, or mechanical methods, depending on desired texture.

3. Dicing and Particle Size Control

Peeled tomatoes are cut into uniform cubes. Typical dice sizes include:

• Small dice: 6–8 mm
• Standard dice: 10–12 mm
• Large dice: 14–16 mm or more

The selected dice size impacts mouthfeel, appearance, and flow behavior

in sauces and spreads. Many suppliers offer multiple size options to meet different application needs.

4. Preparation of Tomato Paste Base

In parallel, another portion of the tomato stream is:

• Crushed and heated to deactivate enzymes.
• Passed through refiners to remove seeds and skins.
• Concentrated in evaporators to a desired brix level (often 28–36°Brix for industrial paste).

This concentrated paste is then diluted and adjusted to achieve the final target solids

in the diced tomato paste product.

5. Blending Dice and Paste

The diced pieces are combined with the paste base in controlled ratios. Key parameters include:

• Dice-to-paste ratio (for chunkiness and viscosity).
• Salt level and acidity (for flavor and preservation).
• Optional herbs or natural flavorings, if the product is pre-seasoned.

6. Thermal Processing and Packaging

• The blended diced tomato paste is heated to a specified temperature.
• It is then filled into cans, pouches, drums, or totes.
• Products may be retorted, pasteurized, or aseptically packed, depending on packaging type and intended shelf life.
