  • Prolonging the shelf life of fresh root vegetables
    Patent number: 4919948
    Abstract: The shelf life of root crops such as raw carrots can be substantially increased by subjecting the raw carrots to a process including (a) a mild heat treatment effective to reduce the microflora of the carrots but not to adversely affect the organoleptic qualities of the raw carrots, (b) the rapid cooling of the heat treated vegetable and placing the vegetable in a sealed container to prevent microbial recontamination and maintain the vegetable in a viable condition.
    Type: Grant
    Filed: January 23, 1989
    Date of Patent: April 24, 1990
    Assignee: DNA Plant Technology Corporation
    Inventors: Avigdor Orr, John O. Spingler, Seymour G. Gilbert
  • Prolonging the shelf life of fresh root vegetables
    Patent number: 4855153
    Abstract: The shelf life of root crops such as raw carrots can be substantially increased by subjecting the raw carrots, in one embodiment, to a process including (a) a mild heat treatment effective to reduce the microflora of the carrots but not to adversely affect the organoleptic qualities of the raw carrots, (b) the rapid cooling of the heat treated vegetable and (c) placing the vegetable in a sealed container to prevent microbial recontamination and maintain the vegetable in a viable condition. In another embodiment, the process includes subjecting the carrots to a vacuum, breaking the vacuum in the presence of water and placing the vegetable in a sealed container to prevent microbial recontamination and maintain the vegetable in a viable condition.

  • Packaged pre-cut vegetables
    Patent number: 4753808
    Abstract: 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.
