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.
Orange juice
The next step is one of the most vital in the processing of orange juice. Pasteurization is important in destroying naturally occurring enzymes that are associated with deterioration of the juice. Pectinesterase is infamous for its deteriorative activity in orange juice. In the pasteurization process, the juice is generally rapidly heated to 197 °F for about 40 seconds. Several industry leaders use flash pasteurization, which is carried out by tubular or plate-type heat exchangers. In order to prevent overheating, turbulent flow is vital to heat the juice rapidly. Cans are filled with the pasteurized juice and inverted immediately to allow the juice to sterilize the inside parts of the lid. The orange juice filled can is sealed and cooled to 90 to 100 °F by spinning on the conveyor belt under cool water sprays. Quality of storage is determined by time and temperature. Juice must be stored at cool temperatures to prevent deterioration.
