Thermal Processing Technology

Choosing the right process In order to be able to produce a product with specific product It is quite common to process both low-acid (pH>4.5) and qualities in the most cost-effective way it is essential to make high-acid (pH<4.5) products in the same UHT plant. However, the correct choice with respect to processing system and tech- only low-acid products require UHT treatment to make them commercially sterile. In many cases the choice is straight forward, but in other cases Spores cannot develop in high-acid products such as juice, and there may be more options to choose between. Some of the...
