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.

The research started in 1942 and it took three years for MacDowell, Moore and Atkins to perfect a method of producing frozen concentrated orange juice that is still utilized today. The process of concentration that was previously being used involved heating the juice so that the water would evaporate. The three researchers invented a process called the cutback process, in which the flavor of orange juice was retained by adding a bit of fresh juice to the concentrate and then freezing it. This new process restored some of the Vitamin C that was lost in heating, thereby creating a more nutritious product. The process helped accelerate the growth of citrus production in Florida and helped create the frozen food industry.
