Abstract

PURPOSE:To obtain roast laver sheet having low degree of contamination with bacteria, without lowering the unique flavor, taste and palatability of laver sheet, by irradiating ultraviolet radiation to a dried laver sheet immediately before and/or immediately after roasting. CONSTITUTION:A dry laver sheet placed and transferred on a net conveyor 41 is roasted with the heater 11 to obtain roast laver sheet. In the above process, the sheet is irradiated with ultraviolet radiation immediately before and/or immediately after the roasting. The irradiation is carried out using the ultraviolet lamps 21 placed above and below the sheet at a dose of 1,000-100,000muw. min/cm<2>. A roast laver sheet having low degree of bacterial contamination can be prepared without lowering the unique taste, flavor and palatability of the laver sheet.
