Developer of Aseptic Bulk Storage Wins Processing Prize

Nelson started developing the aseptic bulk system about 25 years ago. His work in this area of food technology began with research into methods of processing tomatoes.

17/08/07 The developer of aseptic bulk storage and distribution, credited with revolutionising global food trade, has been awarded the "Nobel Prize" of the industry. Philip E Nelson, a retired professor at Purdue University in Indiana, US, was awarded the World Food Prize.

"Bulk storage of food items that have a short shelf life at ambient temperatures has been possible due to efforts of Philip E Nelson in development of huge carbon steel tanks coated with an epoxy resin," the award announcement stated.

Nelson started developing the aseptic bulk system about 25 years ago. His work in this area of food technology began with research into methods of processing tomatoes.

He then moved on to other aspects, such as bulk storage research and the "bag-in-box" system.

Nelson won the award for his constant efforts in developing techniques, which ensure that the nutritional value of fruits and vegetables is maintained during their processing, transport and storage.

In particular he is credited with engineering aseptic techniques of food handling, processing, packaging and delivery that ensure that food-spoiling germs do not survive.
