High Hydrostatic Pressure assisted (HHP) process enhancement for food and allied industries are reported in this paper review. Recently, considerable research has been devoted to the improvement of mild thermal processing techniques and to the development of alternative mild processing technologies. HHP assisted can enhance existing extraction, processes and enable new commercial extraction opportunities and processes. New HHP processing approaches have been proposed, including, the potential for modification of plant cell material to provide improved bioavailability of micro nutrients while retaining the natural-like quality, simultaneous extraction. Therefore, High Hydrostatic Pressure assisted (HHP) technologies could have a strong presence in the future of the biotechnology industry.
