ABSTRACT:
Disclosed are packaged cut produce such as fruit salad mixtures for refrigerated storage which enjoy increased shelf life without the need for gas absorbents. The package includes a sealed imperforate container disposed within which are a quantity of perishable produce cut fruit pieces in a bed having a bed depth of about 1 to 3 inches. The package includes an equilibrium headspace composition comprising by volume of 2 to 5% oxygen, 10 to 15% carbon dioxide and balance nitrogen which, surprisingly, is optimal for substantially all cut produce blends. The package further includes a gas permeable portion such that about 4 to 12 cc. of oxygen is admittable to the package per 24 hr. per oz. of produce. In its method aspect, the present invention provides a method for refrigerated packaging and storage of cut fruit produce in a package of specified oxygen permeability.
