A sterilization unit may include UV sources (90, 100, 110, 120) and a heat source, which may be a broad band UV source, a source of IR or microwave radiation. A combined microwave/UV unit can be used to defrost frozen food and simultaneously sterilize it or maintain sterility. Heating prior to UV irradiation can enhance the sterilization, as can rapid cooling after irradiation. Irradiation can also be enhanced by displacing the food during irradiation e.g. by supporting it on a rotatable support (135) and/or by displacing it relative to the support surface. | |
