Cold-pressed juice
Cold-pressed juice refers to juice that uses a hydraulic press to extract juice from fruit and vegetables, as opposed to other methods such as centrifugal or single auger.
Reverse osmosis
In addition to desalination, reverse osmosis is a more economical operation for concentrating food liquids (such as fruit juices) than conventional heat-treatment processes. Research has been done on concentration of orange juice and tomato juice. Its advantages include a lower operating cost and the ability to avoid heat-treatment processes, which makes it suitable for heat-sensitive substances such as the protein and enzymes found in most food products.
