Prolonging the shelf life of pre-cut fresh celery

Abstract From the Canadian patent

The shelf life of vegetables such as raw celery can be substantially increased by subjecting the raw celery to a process including selecting a portion of the celery that has characteristic chemical and physiological properties found in petioles of market mature celery, (b) slicing the celery to minimize bruising and tissue damage caused by tearing and compression, (c) treating the cut celery with water (d) drying the surface of the cut celery and (e) placing the, pieces of celery in a sealed container to prevent microbial recontamination and maintain the celery in a viable condition.
