Abstract

A method of and an apparatus for producing a packed food, wherein a sheet of packing film of heat resisting and insulating material formed with a multiplicity of minuscule current passing apertures is placed on an insulating container open at the top and the bottom and having an electrode plate and a salt solution impregnated electrical contact member placed thereon which are positioned at the lower open end, and forced into the container in such a manner that the minuscule current passing apertures are in a horizontal plane in contact with the salt solution impregnated electrical contact member. Then a charge of unprocessed foodstuff is filled in the packing film, and an electrode plate is brought, through a salt solution impregnated electrical contact member, into contact with the minuscule current passing apertures and the unprocessed foodstuff positioned thereagainst. Thereafter a current is passed between the two electrodes so as to ripen and sterilize the unprocessed foodstuff into a processed food which is wrapped with the packing film.
