Slice of Laminaria ochotensis Miyabe was dried in an air dryer at 50°C, and the shrunk surface area, the shrinking rate and the dried tissue were investigated quantitatively. Using the shrinkage curve, the shrunk surface area curve was plotted vs. drying time, and it showed nearly a linear shrinkage up to 25min of drying period. When the shrunk surface area curve was expressed vs. moisture content, the shrinkage proceeded in four periods, which were roughly in correspondence to four drying rate periods. From the shrunk surface area curve, the shrinkage characteristic curve, i.e. shrinking rate (cm/cm hr) vs. moisture content, was obtained. Basing on this curve and the drying characteristic (drying rate vs. moisture content), the drying mechanism was clarified more precisely. Concerning the shrinking rate of Laminaria ochotensis Miyabe, it was found that the shrinking rate is largest in the second falling rate period, and lipid in the dried tissue was observed markedly in the cortical layer portion and the medullary layer portion.
