High Pressure Processing extends the shelf life of food products

High Pressure Processing (HPP) is a method of processing food in its sales packaging. As a result, the shelf life of food products is extended multiple times.

High Pressure Processing is suitable for products with a high water content that are packed in watertight, flexible packaging. The products are exposed to pressure of about 6000 bar for 3-6 minutes. The process denaturises pathogens such as listeria, salmonella and norovirus as well as many yeasts and moulds. The properties of the products remain unaltered.

The process chamber has a holding capacity of 350 litres and a production capacity of 1500 kg per hour. In practice, the daily capacity is about one lorryload.

Applications include:

• Ready-made meals

• Packaged meat and fish products

• Prepared salads

• Vegetables, fruit, berries

• Dairy products

• Pet food


Benefits for producers, retailers and consumers:

• Food safety is improved

• The need for preservatives and additives is reduced

• Shelf life is extended

• Food waste is reduced

• Export costs are reduced (products do not need to be frozen)

• It is easier to plan for seasons

• Replaces pasteurisation and heat treatment

• Products’ structure, nutritional values and taste remain unchanged

• A simple method: only water and electricity are used
