1. What Is Tomato Paste?

Tomato paste is a concentrated tomato product obtained by cooking, crushing, refining, and evaporating fresh tomatoes to remove water and increase

the natural soluble solids, mainly sugars and organic acids. In industrial tomato paste, concentration is expressed in degrees Brix, which indicates the percentage of soluble solids.

Tomato paste is widely used as a base ingredient for:

• Tomato sauces and pizza sauces
• Ketchup and condiments
• Ready meals and canned foods
• Soups, stews, and culinary sauces
• Snacks, seasonings, and flavor preparations

2. Tomato Paste Supply Chain Overview

The tomato paste supply chain typically starts with dedicated processing tomato varieties grown on large-scale farms and ends with bulk or retail packaging delivered to food factories around the world.

Each stage adds value and risk, so understanding the sequence is essential for supply chain management and sourcing strategies.

1. Seed selection and nursery preparation
2. Field cultivation and crop management
3. Harvest and field handling
4. Transport of fresh tomatoes to processing plants
5. Reception, washing, sorting, and crushing
6. Refining, concentrating, and standardizing tomato paste
7. Thermal treatment and aseptic filling into bulk packaging (drums, bins, bag-in-box)
8. Storage, warehousing, and inventory management
9. Domestic and international logistics (road, rail, sea)
10. Repacking, formulation, and end-product manufacturing

3. From Seed to Harvest: Farm-Level Stage

3.1 Seed Selection and Tomato Varieties

Industrial Tomato Paste Production uses processing tomato varieties, which differ from fresh market tomatoes. These varieties are bred for:

• High solid content (high Brix) for efficient concentration
• Firm flesh and thick skin for mechanical harvesting
• Uniform ripening and color
• Disease resistance and field durability

3.2 Cultivation and Crop Management

Tomato paste supply chains are highly seasonal. In most producing countries, planting and harvesting are scheduled to feed processing factories during a defined campaign period, often

between 60 and 120 days. Efficient crop management focuses on:

• Optimized irrigation (drip or furrow) to control solids and yield
• Balanced fertilization to support fruit development
• Pest and disease control to maintain quality
• Field planning for easy access to mechanical harvesters

3.3 Harvesting for Tomato Paste

For industrial tomato paste, harvesting is typically mechanized. Harvesters cut the plant, separate fruit from vines, and load tomatoes into trailers or bins.

Harvest timing aims to maximize ripe fruit percentage and color while minimizing overripe or green fruit.

Harvest decisions consider:

• Target Brix level and color development
• Weather conditions (temperature, rain, frost risk)
• Factory capacity and transport availability
• Distance to processing plant (time from field to factory)

4. Field to Factory: Transport and Reception

4.1 Transportation of Fresh Tomatoes

Fresh tomatoes are transported to processing plants as quickly as possible to avoid quality loss. Common transport options include:

• Open-top trailers or trucks
• Large bins handled by forklifts or loaders
• Hopper trucks unloading directly onto reception lines

Time from harvest to processing is usually kept below 24 hours, and in many supply chains below 12 hours, to maintain firmness, prevent fermentation, and reduce spoilage.

4.2 Reception and Raw Material Assessment

At the processing plant, fresh tomatoes are weighed, sampled, and inspected. Typical checks at reception include:

• Net weight of delivery
• Percentage of ripe, unripe, and defective fruit
• Foreign material (soil, stones, plant residues)
• Brix of juice sample
• Color and sensory evaluation

5. Inside the Plant: Tomato Paste Processing Stages

5.1 Washing, Sorting, and Crushing

Once accepted, tomatoes move through a series of processing steps:

1. Washing and destoning: Flumes, sprays, and washers remove soil and foreign material; stones and heavy debris are separated.
2. Sorting: Manual or optical sorting removes defective fruit and non-tomato objects.
3. Crushing / Chopping: Tomatoes are chopped to release juice and pulp.

5.2 Heating and Enzyme Inactivation

The crushed tomato mash is quickly heated to inactivate naturally occurring enzymes that can affect viscosity and color. This hot break or cold break step significantly influences paste characteristics.

5.3 Refining and Pulp Separation

After heating, the mash is passed through refiners or sieves to separate skins, seeds, and coarse fibers from the pulp and serum. Mesh size determines final fineness.

• Single or multi-stage refiners can be used.
• Common sieve apertures: 0.4–1.0 mm, depending on texture requirements.

5.4 Evaporation and Concentration

The refined tomato juice is then concentrated under vacuum in multi-effect evaporators. Vacuum conditions lower the boiling point to preserve color and flavor.

Major goals of this stage include:

• Reach target Brix (e.g., 28–30° or 36–38°)
• Maintain bright red color
• Control viscosity and consistency

5.5 Standardization and Additives

Many industrial tomato pastes are standardized to meet specification limits:

• Salt may be added in small amounts (e.g., 1–2%) for flavor and preservation in non-aseptic products.
• Acidity may be adjusted slightly to ensure microbiological stability.
• In standard commercial tomato paste, artificial colors or preservatives are generally not used, but regulations vary by market.

6. From Paste to Drum: Aseptic Packaging and Formats

6.1 Aseptic Processing and Sterilization

For long-shelf-life industrial tomato paste, aseptic technology is widely used. Aseptic processing typically includes:

1. UHT or HTST heating of concentrated paste (e.g., 115–140 °C for a defined time) to ensure commercial sterility.
2. Cooling to filling temperature under hygienic conditions.
3. Aseptic filling into pre-sterilized bags or packaging inside a sterile chamber.

Aseptic tomato paste does not require chemical preservatives and can achieve shelf life of 12–24 months, depending on packaging and storage conditions.

6.2 Common Industrial Packaging for Tomato Paste

Tomato paste intended for food manufacturing is usually packed in bulk formats. The most common are aseptic bags placed in steel drums or large bins.

6.3 Aseptic Drum Structure

A typical aseptic drum for tomato paste consists of:

• Outer steel drum (metal barrel) providing mechanical protection
• Inner aseptic bag (multi-layer plastic laminate) providing sterile barrier
• Top or bottom valves or fitments for filling and discharge
• Plastic or metal lid and seals to secure the drum

7. Tomato Paste Specifications and Quality Parameters

Industrial tomato paste is traded based on well-defined specifications. Buyers and sellers typically agree on Brix, color, viscosity, defect limits, microbiological status, and packaging details.

7.1 Brix and Concentration Levels

Degrees Brix is the key parameter defining concentration. Different concentration levels serve different applications:

7.2 Color Measurement

Color is a critical quality parameter in tomato paste. It is often measured using colorimeters and expressed as a color score (e.g., a/b ratio in CIE Lab space). Higher a/b ratios represent more intense red color.

7.3 Viscosity

Viscosity influences how tomato paste behaves during pumping, mixing, and in final products. It is usually measured with a Bostwick consistometer or viscometer at a defined temperature and Brix.

7.4 Typical Industrial Specification Sheet

A generic industrial tomato paste specification normally includes the following items.

8. Quality Control and Food Safety in Tomato Paste

14. Frequently Asked Questions About Tomato Paste Supply Chains

14.1 Why is aseptic drum tomato paste so common in international trade?

Aseptic drum tomato paste offers a combination of long shelf life, high product safety, and efficient transport.

The aseptic process ensures commercial sterility without relying on preservatives, while drum packaging protects the paste and allows loading flexibility for containers.

This makes aseptic drums one of the most cost-effective ways to move tomato solids across long distances.

14.2 How is Brix adjusted in tomato paste production?

Brix is typically adjusted during the evaporation stage. Processors control evaporation time and temperature to reach the target Brix.

In some cases, batches can be blended to achieve a consistent final Brix value that meets the contracted specification.

14.3 What is the difference between hot break and cold break paste in final applications?

Hot break tomato paste has higher viscosity and a thicker texture, making it suitable for ketchup, pizza sauce, and products that require body and stability.

Cold break paste has more fresh tomato flavor and lower viscosity, making it better for tomato juices and some types of sauces.

Industrial buyers select the process type depending on their product requirements.

14.4 How long can industrial tomato paste be stored?

Under recommended conditions, aseptic tomato paste in drums can often be stored for 12–24 months.
