Abstract

A packaging material for packaging a selected fluid-containing fresh food item for providing simultaneous curing or marinating of such food item and storage of the same at normal refrigeration temperatures. A packaging material comprises a substrate suitable for contact with food and a food treatment layer comprises a predetermined amount of edible adhesive applied to a food contacting surface of the substrate and a curing or marinating agent mixed in, retained and calibrated by the adhesive. The adhesive is capable of dissolving in fluid from the food at a temperature in the range of −3° C. to −4° C. The amount of curing or marinating agent retained by the predetermined amount of adhesive is that which is required to substantially cure or marinate the selected food item. The amount of the adhesive is determined by the amount of curing or marinating agent required to be retained by it.
