High‑pressure processing (HPP) applies intense mechanical pressure to food, inducing protein denaturation and microbial inactivation while preserving heat‑labile nutrients.
Origin: Japanese (1970s) — Japan
See full technique reference →At pressures of 100–600 MPa, HPP disrupts lipid bilayer fluidity and alters protein conformation, leading to denaturation and aggregation. This mechanical action inactivates enzymes and pathogens without significant heat transfer, thereby maintaining sensory and nutritional quality.
