The minimal processing advantage

Minimal processing methods are designed to preserve the natural taste, nutrients, and texture of food and beverage, altered with the intention to make them safe for consumption. When products are labeled as minimally processed, they seem to appeal to consumers who perceive such products as healthier or fresher. Depending on the method used, not all minimally processed products are entirely free from additives or preservatives. But they are often considered the healthier choice as they reduce reliance on synthetic ingredients.

Current minimal processing technologies include fermentation, high pressure processing (HPP), cold pressing, non-thermal, and gentle mechanical techniques.

Fermentation has boomed in application, from the age-old process for traditional probiotic-rich foods like kefir, kimchi and kombucha, to the innovative platform for plant-based protein and dairy alternatives. Even when fermentation is scaled up, it retains its classification as minimal processing because the underlying method is mild and natural. The process harnesses controlled microbial activity for preservation, flavor, and functional benefits. It is also useful in valorizing food by products into new ingredients, thereby reducing waste.

In HPP, products such as juices, seafood, dairy, and ready-to-eat food, undergo pressures up to 600 MPa to inactivate pathogens without heat. HPP extends shelf life while preserving flavor and nutrients, making it ideal for tropical markets. Many manufacturers of cold-pressed juices and seafood exports rely on HPP.

Another method that does not require heat, cold-pressing is a mechanical extraction using hydraulic presses. It benefits manufacturers of juices, vegetable extracts, and oils. The method can retain most vitamins, enzymes, and natural taste.

Pulsed electric fields (PEF), ultraviolet (UV) treatment, and ultrasound processing are the non-thermal methods in minimal processing. PEF can extend shelf life by using short bursts of electricity to disrupt microbial membranes. UV treatment sterilizes beverages and packaging surfaces. According to PMG Engineering, ultrasound processing in food “offers solutions in crystallization, freezing, extraction, filtration, emulsification, sterilization, and more. It ensures nutrient retention, minimizes microbial load, and supports sustainable production.”

Low-temperature dehydration sits between minimal and moderate processing, and is said to be gentle enough to retain flavor and nutrients compared to high-heat drying.

Equipment designed for minimal processing

Many global manufacturers are driving innovation in minimal processing, offering equipment that producers in Southeast Asia can adopt to meet consumer demand and regulatory requirements.

HPP system from Avure (JBT)

The AV-40X to AV-70X expandable HPP systems from Avure Technologies offer modular expansion. They are applicable for high-volume beverage and packaged food production. For instance, the AV-S Seafood HPP Machine is a vertical design that increases yield by 30% and reduces shell fragments.

Hiperbaric has introduced the Hiperbaric 525 HPP, an HPP system particularly suited for large-scale beverage and ready-to-eat food production.

The Precision and Biomass Fermentation Upscaling Line from GEA Group supports the production of animal-free proteins, enzymes, and functional biomolecules. It scales precision fermentation and biomass fermentation industrially, enabling natural processes to meet modern demand such as those for dairy alternatives and plant proteins.

A specialist in Pulsed Electric Field (PEF) systems, Elea Technology GmbH offers belt, extraction, as well as inactivation systems for a wide range of F&B applications. The PEF Advantage Belt Systems (including the Advantage B 1 for compact lines or Advantage B 1000-850) is for large-scale operations of snacks to beverages. Its latest Advantage™ Belt PEF System is designed for processing roots, tubers and fruits: short electrical pulses are applied to food as it passes along the conveyor belt. These pulses permeabilize cell membranes in order to soften the tissues as well as to inactivate microorganisms without the use of heat.

Packaging that complements minimal processing

Food processing alone is not enough to guarantee product quality and shelf life. Advanced packaging technologies help extend shelf life especially of minimally processed foods where additives and preservatives are reduced.

Modified Atmosphere Packaging (MAP), aseptic systems, and advanced sealing equipment are the complementary technologies. MAP extends shelf life by altering the gas composition inside packaging. Aseptic systems provide sterility during filling and packaging, allowing products like cold-pressed juices or dairy alternatives to remain safe and stable. Sealing equipment prevent contamination.

Smart packaging solutions also integrate with non-thermal processing methods, ensuring microbial safety while preserving taste and nutrients.

Multivac continues to innovate in packaging with its advanced form-fill-seal machines designed for fast changeovers. These systems are widely used in meat, dairy, and snack processing.

Syntegon has developed Amplified Heat Sealing (AHS) Systems, which deliver tight seals and longer shelf life while being compatible with sustainable mono-materials. This innovation supports bakery, confectionery, and dairy producers seeking to balance minimal processing with sustainability.
