<p>A casing for containment of a proteinaceous product during or following processing is described. The casing has controlled porosity which permits close control of product drying with protein retention, providing good product color and surface texture, patterned and/or shaped products, high protein content and high peelability. The casing is a laminate of a first lamina having high strength and, optionally, surface pattern-producing capability, and a second lamina of controlled porosity which is permeable by vapors and, in most cases, also aqueous and organic liquids, but which is not permeable to solids such as proteins or fats. The laminae are adhered by an adhesive (preferably thermally activated) or by surface interlocking. Accessory materials such as liquid flavorants, colorants, release agents and anti-microbial agents can be incorporated into the laminae and from there imparted to the product. Applicable proteinaceous products include meat, poultry, seafood, soya and cheese.</p> |
