## 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.

## Claims

### Claim 1

A packaging material for wrapping a selectable fluid-containing fresh food item having a particular size and weight and providing simultaneous curing or marinating and storage of said food item at normal refrigeration temperatures, said packaging material comprising:
(a) a substrate suitable for contact with food; and,
(b) a food treatment layer applied to a first food contacting surface of said substrate, said food treatment layer comprising a predetermined amount of a curing or marinating agent mixed in and throughout a predetermined amount of edible adhesive, wherein said adhesive dissolves in fluid from said fresh food item when said food treatment layer is placed in contact with said fresh food item at a temperature in the range of −3° C. to +4° C., said adhesive being present in a calibrated amount sufficient to hold said predetermined amount of said agent and adhere said agent to said substrate and said agent being present in an amount sufficient to cure or marinate said fresh food item of said particular size and weight when said fresh food item is stored at said temperature range and said adhesive dissolves in said fluid at said temperature range.

### Claim 2 (depends on 1)

A packaging material according to claim 1 wherein said substrate is a film substantially impermeable to air and microorganisms.

### Claim 3 (depends on 2)

A packaging material according to claim 2 wherein said film has a further said food treatment layer applied to a second food contacting surface of said film opposite to said first food contacting surface.

### Claim 4 (depends on 3)

A packaging material according to claim 3 wherein said fresh food item is muscle cut meat.
