Beverage pasteurization

Beverage pasteurization is the heat-treatment to eliminate micro-organisms present and to ensure the desired shelf life for the beverage. The carefully designed pasteurization process safeguards flavours and nutrients in the beverage product.

The pasteurization conditions are chosen for each beverage based on its specific properties. The temperature ranges from 85°C for juices to 138°C for Asian teas and the holding times typically vary between 5 and 30  seconds.

For beverages that are packaged aseptically and do not require refrigeration, it is necessary that aseptic conditions are secured throughout the process, preventing any recontamination of the pasteurised product. Other pasteurization systems are designed for cold-filling, where the hygienically filled beverage is distributed in the cold chain, or for hot-filling of beverages to be shipped at ambient conditions.

Tetra Pak’s pasteurisation systems are designed for high energy recovery and minimal product waste that ensure low operating costs and maximum protection of the environment. The flexibility to handle a wide range of beverages in the same pasteurisation system, allows producers to respond quickly to new market needs.
