High‑pressure processing (HPP) applies 400–600 MPa for 5–10 minutes to inactivate pathogens while preserving raw‑like texture.
Origin: Modern food technology (21st century) — Global
See full technique reference →HPP induces reversible protein unfolding and limited denaturation, preventing gelation. Enzymes such as polyphenol oxidase are inactivated, extending shelf life without heat‑induced Maillard reactions. The mechanical pressure disrupts microbial membranes, achieving ≥5‑log reductions with minimal temperature rise.
