High Pressure Processing Technology and Equipment Evolution : A Review

Abstract

High pressure processing (HPP) is an interesting non-thermal technology that involves the sterilization of food by the mean of ultra-high pressures, which lead to extending the shelf life of processed food, as well as maintaining nutritional value and quality of food products. The consumers' increasing demand for this new products graped the interest of several already-existing high pressure equipment manufacturers around the globe. The successful of this technology encouraged them to enter the field of food processing and adjust their existing technologies to adapt to the new process. This review spots the major discoveries in HPP equipment history, describes the current applications of HHP in processing and provides comprehensive information about HPP equipment technology used in commercial and research applications. In addition, this paper presents the major manufacturers in HPP equipment industry around the world.

A review of sustainable and intensified techniques for extraction of food and natural products

“…The current market of HP equipment is shared among companies such as Hiperbaric, Avure, and Multivac that are the main contributors to the development of this technology. 135,136 As a leading company in the sector of HP equipment, Hiperbaric has been operating in this market since 1999. Its first application in 2002 was dedicated to treat dry cured meat products and later ready-to-eat products elaborated by Campofrío (Spain).…”

Sublethal Injury and Viable but Non-culturable (VBNC) State in Microorganisms During Preservation of Food and Biological Materials by Non-thermal Processes

“…Current applications of HHP are solely operated in batch mode, with the treatment of the final product being carried out within a flexible packaging. For this purpose, the packaged goods are placed in a pressure vessel, which is linked to a high pressure pump and a corresponding pressure intensifier ( Elamin et al, 2015 ). The vessel is filled with a pressure transmitting liquid, e.g., water, and additional water is pumped into the system in order to increase the pressure.…”

“…HHP treatment is a so-called isocratic process, i.e., the pressure transmission is immediate and its distribution is multidirectionally homogeneous. Consequently the same pressure treatment applies to all goods within the treatment chamber, regardless of product size and shape ( Elamin et al, 2015 ). However, temperature non-uniformity may occur during the treatment due to heat losses toward the wall of the pressure vessel.…”

Cold extraction of phenolic compounds from watercress by high hydrostatic pressure: Process modelling and optimization

“…In addition, the higher the hydrostatic pressure is, the more solvent can enter cells and the more compounds can permeate out to the solvent [25,26]. Despite the considerable cost of the HHP equipment, processing can become cheaper compared to conventional methods that demand temperature and long processing times [27]. Therefore, the equipment costs could be repaid back in long-term usage.…”
