Sous vide foods are chilled products packed in vacuum-sealed pouches and preserved by the sous vide process. This gentle heat treatment gives them better shelf life than non-vacuum cook-chill methods, while reported eating-quality gains include better texture, colour, and flavour retention. Typical products include fruits in syrups and many catered meals. The vacuum pouch excludes oxygen and the gentle cooking avoids the damage of aggressive heating, but the absence of a full sterilizing step makes validated pasteurization schedules and uninterrupted refrigeration the non-negotiable safety controls.
