Premium Quality Refrigerated Vegetable Products and Methods of Making Them

The disclosure relates to methods of treating whole, cut, or other processed botanical ingredient(s) in a manner that reduces the load of viable food-contaminating organisms (human or other animal pathogens and food spoilage organisms), preferably without substantially altering one or more of the organoleptic properties of the ingredient(s). The method includes subjecting a botanical foodstuff to a high pressure processing (HPP) treatment and to aseptically sealing the foodstuff within a package that contains a microbistat. Such treatments improve the storage stability of the foodstuff and preferably do not significantly alter one or more organoleptic properties of the botanical ingredient(s). Packaged foodstuffs treated as described herein exhibit beneficial properties, such as retention of taste, appearance, and texture and extended shelf life, relative to non-treated foodstuffs.
