Hot food can be kept in a thermos for about 5 to 7 hours if the thermos is preheated with boiling water for a few minutes before adding the food. Make sure the food is steaming hot when placed in the thermos to maximize heat retention. After 7 hours, the temperature may drop below the safe threshold for hot foods, so it's best to consume it within that time frame to avoid any risk of foodborne illness.
