Abstract: A carrier is provided for high pressure processing of food (HPP), beverage, cosmetic, pharmaceutical, or biological products at moderate temperatures in horizontal machines. The carrier includes a cylindrical body, an inner space to accommodate the products, and one or more small openings longitudinally distributed along the carrier side wall. The carrier also has one or several inner pieces, acting as ballast, placed on the diametrically opposite side wall of the openings. The one or several inner pieces are coated by one or more sheets of a material with high adiabatic heating properties upon compression.

Abstract: A method for preparing beverages by extraction, employing high-pressure processing (HPP), for the bulk production of enriched beverages, ready for consumption and with an extended useful life. The method uses high hydrostatic pressures to perform a solid-liquid extraction and/or infusion (e.g. cold infusion) with an improved extraction rate and/or yield, and simultaneously inactivating spoilage and pathogenic micro-organisms to increase its safety and useful life. The method includes placing a mix (8) of solids and liquids in a bag (3) located within a vessel (4) and pressurising same to a pre-set pressure (up to 800 MPa) and maintaining said pressure (10) for a pre-set period of time. The method includes the subsequent depressurisation of the vessel (11) and the removal of the mix from the bag (12), filtering the same under ultra-clean conditions (13), thus obtaining a safe, particle-free beverage, enriched with the extracted compounds of interest.
