Description
Cold pasteurization uses low‑temperature long‑time heating (55–65 °C for 30–60 min) to inactivate vegetative pathogens while preserving nutrients and sensory quality.
Technical
The process relies on the thermal death time (D‑value) of target microbes; at 60 °C a 10 D‑time is required for Listeria monocytogenes, while spores remain resistant. Heating denatures proteins and inactivates enzymes, but the mild temperature limits Maillard browning and nutrient loss.
