Abstract: Disclosed are packaged cut product blends of vegetables salad mixtures for refrigerated storage which enjoy increased shelf life without the need for gas absorbents or anti-oxidants. The package includes a sealed imperforate container disposed within which are a quantity of perishable produce cut pieces with reduced respiratory rates in a bed having a bed depth of about 1 to 6 inches. The package includes an equilibrium headspace composition comprising by volume of 1.5 to 0.8% oxygen, 8 to 12% carbon dioxide and balance nitrogen which, surprisingly, is optimal for reduced aerobic respiration rates for substantially all cut produce blends. The package further includes a gas permeable portion such that about 18 to 32 cc. of oxygen is admittable to the package per 24 hr. per oz. of produce.
