Tomato Paste 36–38%CB: Technical Overview and Industrial Applications

Tomato paste is a cornerstone ingredient in industrial food processing, offering concentrated flavor, vibrant color, and functional versatility. Among the various grades of tomato paste, tomato paste 36–38%CB—denoting a cold-break (CB) processed paste with 36–38% soluble solids—has become a preferred option for applications that require high color retention, fresh taste, and precise viscosity control. Its concentrated nature enables reduced transport volumes and consistent performance in sauces, Soups, ketchups, and ready-to-eat meals, meeting the stringent demands of professional kitchens and industrial manufacturers.

Despite appearing simple, producing high-quality 36–38%CB tomato paste requires rigorous control across tomato selection, processing techniques, thermal management, and packaging. This article provides an in-depth exploration of the product, including market context, key technologies, quality considerations, supply-chain criteria, common industry challenges, applications, and emerging trends.

1. Industry Background and Market Demand

The global tomato paste market has experienced sustained growth driven by urbanization, increasing demand for processed foods, and the expansion of quick-service restaurants and ready-meal production. Industrial users require tomato pastes that deliver consistent viscosity, bright color, and stable flavor to ensure uniform results across batches.

Tomato paste 36–38%CB is particularly suited for these needs:

• Industrial food manufacturing: Offers concentrated tomato solids for sauces, ketchups, soups, and ready meals.

• Culinary consistency: Cold-break processing maintains bright red color and fresh taste even during high-temperature cooking.

• Logistics efficiency: High-solids paste reduces handling, storage space, and shipping costs.

• Flavor uniformity: The 36–38% soluble solids range ensures predictable acidity, sweetness, and texture across batches.

As global demand for processed and convenience foods continues to rise, cold-break tomato paste with high Brix levels has become a critical ingredient in professional food production.

2. Core Concepts and Key Processing Technologies

2.1 Cold-Break (CB) Processing

Cold-break processing involves crushing tomatoes and heating the pulp to 55–65°C, a temperature range low enough to preserve natural pectin and enzymes. Unlike hot-break processing, CB preserves a fresher flavor, brighter color, and higher acidity, producing a tomato paste with a thinner but more vibrant consistency.

• Advantages of CB processing:

• Maintains fresh flavor profile

• Preserves bright red color for visual appeal

• Retains natural acidity and volatile compounds

• Supports functional versatility in culinary applications

CB tomato paste is preferred in applications requiring intense color and fresh taste, such as premium sauces and ketchup formulations.

2.2 Soluble Solids Concentration

The 36–38% Brix range is a defining feature of this product. Soluble solids influence:

• Viscosity and mouthfeel: Ensures the paste integrates smoothly in formulations

• Color intensity: Enhances visual appeal in final products

• Flavor balance: Provides a natural sweetness-acidity profile

Evaporation systems, including falling-film or multi-effect evaporators, concentrate the tomato pulp to the desired Brix level while minimizing thermal degradation.

2.3 Refining and Homogenization

After concentration, paste is refined to remove seeds, skin, and coarse particles, followed by homogenization to ensure uniform texture. This step is critical to maintain smoothness, improve heat transfer during processing, and enhance product stability.

2.4 Thermal Handling and Packaging

Although CB paste retains fresh qualities, it still requires careful thermal management for microbiological safety:

• Filling temperature: Typically conducted under mild heat to preserve color and flavor

• Sterilization/retort: Used for extended shelf life in canned or bulk paste

• Packaging integrity: Barrier properties and seal quality ensure oxygen and light protection, preventing oxidation and color loss

Proper packaging and thermal control are essential to preserve the characteristic CB qualities of bright color, fresh flavor, and smooth texture.

3. Product Structure, Materials, and Manufacturing Workflow

3.1 Raw Material Specifications

High-quality tomato selection is critical for producing consistent 36–38%CB paste:

• Fully ripened tomatoes for optimal sugar content and lycopene levels

• Low variability in acidity to support precise Brix levels

• Minimal defects such as mold, rot, or pest damage

3.2 Packaging Materials

Packaging must withstand mild heat and maintain barrier integrity:

• Tinplate cans: Provide long-term storage and retort stability

• Flexible laminated pouches: Allow hot-fill or mild-fill processing with reduced weight

• Industrial drums: For bulk industrial use

Material selection ensures oxygen and light protection, mechanical resistance, and compatibility with thermal processing.

3.3 Manufacturing Workflow

The production process for 36–38%CB paste typically includes:

1. Sorting and washing of tomatoes

2. Crushing and cold-break heating (55–65°C)

3. Evaporation to achieve 36–38% soluble solids

4. Refining and homogenization for smooth texture

5. Filling into sterilized packaging

6. Mild sterilization or retort

7. Cooling, inspection, and packaging for distribution

Monitoring systems track Brix, pH, viscosity, color, and microbial safety at critical points.

4. Factors Influencing Quality and Performance

Quality and consistency of 36–38%CB tomato paste depend on multiple variables:

• Raw tomato variability: Seasonal differences in sugar, acidity, and moisture can affect color, taste, and viscosity

• Thermal processing accuracy: Excessive heat can reduce brightness and flavor; insufficient treatment risks microbial contamination

• Refinement efficiency: Particle size and homogeneity influence texture and heat transfer

• Packaging integrity: Poor sealing or compromised barriers reduce shelf life

• Storage conditions: Exposure to high temperatures, light, or oxygen accelerates oxidation and quality deterioration

5. Supply Chain and Supplier Selection Standards

Industrial buyers should consider:

• Certifications: HACCP, ISO 22000, BRC/GFSI

• Traceability: Farm-to-factory documentation ensures accountability

• Production capacity: Suppliers must manage consistent output across seasonal peaks

• Packaging reliability: Verified barrier properties, seal strength, and retort performance

• Distribution readiness: Compliance with international labeling, health certifications, and transport standards

6. Common Industry Challenges

• Raw material cost volatility due to weather, water availability, or crop yield fluctuations

• Variability in Brix and acidity impacting formulation consistency

• Heat-induced degradation affecting color and flavor

• Packaging failures leading to spoilage or non-compliance

• High-volume logistics requiring precise synchronization between production and distribution

7. Application Scenarios and Use Cases

36–38%CB tomato paste is versatile across industrial applications:

• Sauces and gravies: Provides vibrant color and smooth texture

• Ketchups and condiments: Forms a stable base with bright appearance

• Soups and ready meals: Enhances flavor and viscosity

• Industrial batching: Supports consistent mixing in large-scale formulations

The cold-break process preserves visual and sensory qualities, making it suitable for premium and visually demanding products.
