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.
Edwin L. Moore
Moore went to the Citrus Research Center in Lake Alfred to enhance commercial evaporation methods and also studied the chemical characteristics of the new juice. A patent was awarded in 1948 on the process they developed, but it was claimed by the USDA, which cited the use of its facilities. Moore's work on the project helped establish minimum quality standards for frozen concentrated orange juice.
