Cold-pressed juice
After extracting juice from fruits and vegetables, the juice may be consumed raw, or the manufacturer may choose to put the juice through a preservation method such as HPP in order to extend shelf life and kill potentially harmful microorganisms. The HPP process allows the juice to be stored for about 30 days.
Anthony T. Rossi
A major breakthrough came in 1954, when Rossi invented and patented a pasteurization process to aseptically pack pure chilled juice in glass bottles, allowing it to be shipped and stored without refrigeration. For the first time, it was possible to offer the consumers over a widespread area the fresh taste of orange juice made from 100-percent fruit. Soon thereafter, he also devised a method of freezing pure whole citrus juice in blocks for storage and shipping.
