When analyzing consumption forecasts worldwide for sensitive beverages, it’s easy to see a trend of growth, and this trend is much more evident in the developing countries. One interpretation of these data is that there is a developing tendency for people to look for higher quality products.
Aseptic is a multi-disciplinary approach to the filling of sensitive beverages with the aim of preserving the natural properties of each product in terms of colour, taste, texture, chemical, microbiological and nutritional aspects. Many disciplines contribute to the final result: packaging design, plastic material generation, packaging manufacturing and sterilization, product sterilization and aseptic filling and capping. This is the main reason for the creation of the second edition of this book: to open the aseptic world to all the contributions and to give to the reader a better understanding of what is behind that nice bottle of orange juice or milk that everyone has in their refrigerator every day.
A second important reason is to give readers an update about the technical developments in aseptic bottle filling since the sterilization focus changed from bottles to preforms. We, at GEA Procomac still expect a long life for the trusted Peracetic Acid sterilization technology, but we welcome preform sterilization and Aseptic Blowing as the aseptic technology of the future.
