Blast chilling should now be used in all commercial restaurants, cafes and bistros; basically anywhere that prepares and serves food to the public. When blast chilling first came about it was not compulsory to integrate this practice into daily routines however as the concern for safe guarding the public against potentially harmful bacteria was addressed, food safety regulations now firmly advise that blast chilling is a critical practise for any food preparation businesses which plan to later regenerate pre-prepared foods.
