Safterei
The cold-pressed juices produced by Safterei are made by a form of pasteurization known as Pascalization or High pressure processing (HPP). Instead of using heat for preservation, the raw juice is exposed to be pressured by thousands of pounds. Using this method the flavor and the nutritional value of the juice is not damaged.
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.
