1. What Is Diced Tomato Paste?

In the industrial tomato processing sector, the phrase diced tomato paste commonly refers to

a blended product that combines firm tomato dices with a concentrated tomato base or

tomato paste. This hybrid ingredient delivers both:

• Visible tomato pieces (dices) for texture and visual appeal
• Thick, concentrated tomato matrix for color, flavor, and soluble solids

It is used extensively in mass-produced pasta sauces, pizza sauces, ready meals, and

foodservice sauces because it provides a consistent tomato identity while allowing manufacturers to tailor

viscosity, flavor intensity, and particulate size.

1.1 Distinguishing Diced Tomato Paste from Other Tomato Products

Diced tomato paste differs from other industrial tomato ingredients in several ways:

For pasta sauce manufacturing, diced tomato paste offers a balance between the functionality of tomato paste

and the sensory impact of diced tomatoes, making it ideal for chunky pasta sauce styles that

require both body and visible tomato pieces.

2. Role in Mass-Produced Pasta Sauces

In mass-produced pasta sauces, diced tomato paste functions as a primary structural ingredient,

not merely a flavoring. Its performance directly affects:

• Final sauce texture and chunkiness
• Consistency and viscosity during processing and filling
• Color stability during shelf life
• Tomato flavor intensity and sweetness/acid balance
• Yield and cost efficiency per unit of finished sauce

2.1 Core Functional Roles

• Texturizing agent: Provides firm tomato particles that maintain integrity after thermal processing.
• Color contributor: Supplies natural red color through lycopene-rich tomato solids.
• Flavor carrier: Concentrated base enhances umami notes and overall tomato taste.
• Body builder: Increases soluble solids to achieve desired sauce thickness.
• Water binder: Helps reduce syneresis (water separation) in bottled or jarred sauces.

2.2 Benefits for Large-Scale Producers

Because diced tomato paste integrates multiple functions into a single ingredient, it is especially popular in

mass-market pasta sauces, private label lines, foodservice sauces, and ready meal components

where process reliability and consistent sensory attributes are critical.

3. Key Definitions and Technical Terms

Understanding standard technical terminology around diced tomato paste and industrial tomato ingredients

helps clarify specifications and supplier communications.

3.1 Core Definitions

• Diced Tomatoes: Tomato flesh cut into regular cubes. Common industrial dice sizes include

  10 x 10 mm, 12 x 12 mm, 14 x 14 mm, and 20 x 20 mm, depending on application.

• Tomato Paste: Concentrated tomato product obtained by evaporating water from tomato

  juice or puree. Standard industrial tomato paste is identified by its Brix (soluble solids) level.

• Diced Tomato Paste (Blend): A product composed of diced tomatoes suspended in a matrix

  of tomato paste or concentrated tomato puree, often packed aseptically for industrial use.

3.2 Brix and Soluble Solids

Brix (°Bx) is a key parameter that expresses the soluble solids content of tomato products,

mainly representing sugars, acids, and some soluble pectins.

• Higher Brix = thicker, more concentrated tomato base
• Lower Brix = thinner, more watery product

3.3 Other Technical Terms

• Aseptic: A processing and packaging method where the product is sterilized, then filled

  into pre-sterilized containers in a sterile environment, yielding long ambient shelf life.

• pH: Measure of acidity. Tomato products typically have pH around 4.0–4.4, which allows

  high-acid thermal processing conditions.

• Peeled / Unpeeled: Describes whether the tomato dices retain skin. Many industrial

  diced tomato pastes use peeled tomatoes for better mouthfeel.

• Serum: The liquid portion surrounding solids (dices) in a tomato product; its viscosity

  strongly influences sauce texture.

• Syneresis: Separation of clear liquid from a sauce or puree, an undesirable quality

  defect in commercial pasta sauces.

4. Raw Material Requirements

The performance of diced tomato paste in pasta sauce manufacturing depends heavily on the quality and

characteristics of the raw tomatoes used.

4.1 Tomato Varieties Used

Industrial diced tomato paste is generally produced from processing tomato varieties rather

than fresh-market table tomatoes. Characteristics of suitable varieties include:

• High firmness and dense flesh for good dice integrity
• Relatively low seed and juice ratio
• Good color (deep red) and high lycopene content
• High Brix to increase processing efficiency
• Uniform shape and size for consistent dicing

4.2 Maturity and Harvest Parameters

Tomatoes destined for diced tomato paste should be harvested at optimum ripeness:

• Color: Fully red but still structurally firm
• Defects: Minimal skin damage and mold
• Solids: Adequate natural Brix to reduce energy cost in concentration

4.3 Additional Ingredients in Diced Tomato Paste Blends

Industrial diced tomato paste for pasta sauces is often processed as a 100% tomato product.

However, some variants may legally and technologically include:

• Salt (for flavor and water activity control)
• Acidifiers (e.g., citric acid) to adjust pH
• Calcium salts (e.g., calcium chloride) to enhance dice firmness
• Natural flavor concentrates from tomato

Formulation must comply with local regulatory definitions for standardized tomato products in the intended

market.

5. Processing Technology for Diced Tomato Paste

The production of diced tomato paste used in mass-produced pasta sauces integrates dicing,

concentration, and aseptic packaging. While exact process designs differ,

the general steps are broadly similar across the industry.

5.1 Overview of Process Flow

2. Washing and sorting
3. Optional peeling and coring
4. Dicing into predetermined cube size
5. Blanching or preheating to firm dices and inactivate enzymes
6. Preparation of tomato paste or concentrated base
7. Blending of dices with concentrated tomato base
8. Standardization of Brix, pH, and salt (if used)
9. Thermal treatment (e.g., HTST or UHT)
10. Aseptic filling into bulk industrial packaging

5.2 Dicing Operations

Tomatoes are diced using specialized cutting machines that aim to minimize mechanical damage. Critical

parameters include:

• Uniform cube size
• Minimal juice loss during cutting
• Limited ragged edges or crushed pieces

5.3 Pretreatment of Dices

To maintain dice integrity during later processing and pasta sauce cooking, diced tomatoes often undergo:

• Blanching: Short heating step to inactivate pectin-degrading enzymes.
• Calcium treatment: Where permitted, calcium salts may be used to strengthen cell walls.

5.4 Preparation of Concentrated Tomato Base

The tomato paste component is produced from:

1. Crushing or pulping whole tomatoes
2. Heating to inactivate enzymes and reduce microbial load
3. Removing skin and seeds (depending on desired smoothness)
4. Evaporating water in vacuum evaporators to target Brix levels

For diced tomato paste blends intended for pasta sauces, this base is usually diluted or standardized to

intermediate Brix before being combined with dices.

5.5 Blending, Standardization, and Thermal Processing

The diced component and concentrated base are carefully blended to achieve:

• Defined dice-to-serum ratio
• Target Brix (e.g., 12–16 °Bx for many sauce bases)
• Controlled pH (often around 4.1–4.3)

After blending, the product is thermally processed to commercial sterility, often using:

• High-temperature short-time (HTST) heat exchangers
• Or ultra-high-temperature (UHT) systems for aseptic products

5.6 Aseptic Packaging

Aseptic technology is widely used for diced tomato paste destined for pasta sauce manufacturing. This enables:

• Ambient storage
• Long shelf life (often 12–24 months)

15. Frequently Asked Questions (FAQ)

15.1 Is diced tomato paste the same as diced tomatoes?

No. Diced tomatoes are pieces of tomato in their own juice or lightly concentrated liquid, usually with

relatively low Brix. Diced tomato paste refers to dices suspended in a thicker, more concentrated

tomato base, creating a higher-solids product suited for pasta sauce manufacturing.

15.2 Why use diced tomato paste instead of just tomato paste?

Tomato paste alone is smooth and lacks texture. Diced tomato paste provides both concentrated tomato flavor

and visible tomato chunks, which consumers often associate with premium or homemade-style

pasta sauces.

15.3 Can diced tomato paste be used directly to make ready-to-eat pasta sauce?

Yes. Many manufacturers use diced tomato paste as the main base for ready-to-eat pasta sauces. Additional

ingredients such as oil, herbs, spices, salt, and sometimes sweeteners are needed to reach the final flavor

profile and consistency.

15.4 How does Brix level affect pasta sauce formulations?

Higher Brix diced tomato paste provides more solids and thicker body. This may reduce

cooking time and energy use but also means more dilution or additional ingredients may be required to reach

the desired taste and texture. Lower Brix products yield lighter sauces but may require longer reduction

times if a thicker texture is desired.

15.5 Are there any typical allergens in diced tomato paste?

Standard diced tomato paste made from tomatoes, with optional salt and acidifiers, does not usually contain

common allergens. However, always refer to product specifications and labels to confirm the absence of any

added ingredients that might be allergens according to local regulations.

15.6 Is diced tomato paste suitable for vegetarian or vegan pasta sauces?

Yes. When composed solely of tomato and permitted processing aids, diced tomato paste is suitable for

vegetarian and vegan applications. Pasta sauce formulations must also be reviewed to ensure all other

ingredients meet the desired dietary criteria.

15.7 What is the typical shelf life of aseptic diced tomato paste?

Aseptic diced tomato paste often offers a shelf life of approximately 12–24 months under

recommended storage conditions. Specific duration depends on the product formulation, packaging, and

producer’s validated stability data.

15.8 How should diced tomato paste be stored at a pasta sauce plant?

Store in a dry, cool, and clean environment, protected from direct sunlight and extreme temperatures. Follow
