  • Patent number: 5200219
    Abstract: Fresh green beans in a plastic container that have an extended shelf life, the green beans being treated to slow down the normal deterioration of the beans by immersing the green beans in water at a temperature and for a time sufficient to cool the interior of the beans to that temperature, to sanitize the beans by removing spores and bacteria, and to replace some of the water lost by the beans after harvesting. After the immersion step, the moisture is removed from the surface of the green beans at a temperature of 40.degree. F. to 44.degree. F., and thereafter the beans are graded and packed into the plastic container, keeping the bean temperature below 48.degree. F.
    Type: Grant

  • Patent number: 4867996
    Abstract: Fresh green beans in a plastic container that have an extended shelf life, the green beans being treated to slow down the normal deterioration of the beans by immersing the green beans in water at temperatures of 32.degree. to 38.degree. F. for a time sufficient to cool the interior of the beans to that temperature, to sanitize the beans by removing spores and bacteria, and to replace some of the water lost by the beans after harvesting. After the immersion step, the moisture is removed from the surface of the green beans at a temperature of 40.degree. to 44.degree. F., and thereafter the beans are graded and packed into the plastic container keeping the bean temperature below 48.degree. F.
