From Field to Factory: The Aseptic Process Behind Premium Tomato Paste

The journey of aseptic tomato paste begins long before it reaches the factory floor. Behind every drum or IBC of high-quality tomato concentrate lies a carefully managed process — from selecting the right tomato varieties to advanced aseptic sterilization. Understanding this process helps food manufacturers appreciate why aseptic tomato paste delivers unmatched quality, safety, and consistency.

From Fresh Tomatoes to Concentrate

It all starts in the fields. Only fully ripe, healthy tomatoes are selected for processing to ensure a deep red color and natural sweetness. Within hours of harvesting, the tomatoes are washed, sorted, and crushed.

The pulp is then heated to deactivate enzymes that could affect taste and texture. After that, the juice is filtered and concentrated under vacuum conditions until it reaches the desired Brix level — typically 28–30% or 36–38%, depending on customer requirements.

The Aseptic Sterilization Process

Once the concentration is achieved, the next critical step is aseptic sterilization. Both the tomato paste and the packaging material are sterilized separately at high temperatures. The paste is then cooled and filled into sterile containers — such as 220L drums or 1,000L IBCs — in a completely bacteria-free environment.

This process guarantees that the product remains shelf-stable for up to two years without the use of preservatives or refrigeration, maintaining its natural flavor, color, and nutritional value.

Quality Control and Traceability

Each batch of aseptic tomato paste undergoes strict laboratory testing to verify its acidity, color, viscosity, and microbiological purity. Traceability is maintained throughout the entire process — from the farm to the final shipment — ensuring complete transparency and product safety.

From Factory to You

After packaging, the product is carefully stored and transported to customers around the world. Because of its aseptic nature, it arrives ready for immediate use in manufacturing sauces, soups, ketchup, and ready meals.

The aseptic process is what makes modern food production both efficient and safe.
