I have a mea culpa. I suspect I was conflating ‘pasteurisation’ with ‘sterilisation’.
(NB. if anyone else is reading this; pasteurisation ensures the fresh food you eat is safe, sterilisation is what they do to the food they send to the space station. Fresh food does not automatically equal safe food.)
But the most definitive advice I’ve been able to find from Baldwin is:
Pasteurized food should be served immediately or stored below 3°C (37°F) and consumed or chilled/refrigerated within a specified time period.
Helpful.
