High‑pressure pasteurisation of guacamole uses 400–600 MPa for 5–10 minutes at near‑ambient temperatures to inactivate pathogens while preserving nutrients and flavor.
Origin: Aztec (pre‑Hispanic) — Mesoamerica
See full technique reference →The process applies hydrostatic pressure to disrupt microbial cell membranes and denature enzymes such as polyphenol oxidase, while the low temperature limits thermal degradation of heat‑labile compounds like vitamin C and volatile aldehydes. Pressure also reduces oil phase separation when emulsifiers are present, maintaining a stable creamy texture.
