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. |
