摘要：
Methods for extending the shelf-life of crops (e.g., roots, tubers, bulbs, corms, rhizomes and similar commodities), involving washing the crops (e.g., ginseng roots) in an aqueous solution containing about 50 ppm to about 500 ppm sodium hypochlorite and subsequently coating the crops with an aqueous solution containing chitosan and at least one organic acid (e.g., lactic acid, levulinic acid, acetic acid), and placing the crops in modified atmospheric packaging. The shelf-life of crops can be extended by up to about 38 weeks.
