This study was carried out to develop the intermediate material for its processing product of sea tangle by investigating softening stability of softened sea tangle for storage. The change of softening stability, Avrami (equation) exponent, color and sensory characteristics was examined during storage when hydrophilic softening agent was added to the softened sea tangle. Inclination of the sample added with isomalto oligosaccharide showed the lowest value in relation of ln(E_L/- Et) vs t for four days of storage. Exponent range of Avrami equation was 1.00-1.67 and isomalto oligosaccharide having 1.0 of exponent exhibited the most stable effect in softerness. The sample formulated with isomalto oligosaccharide indicated the lowest value in rate constant and its rigidity was progressed very slowly during storage. The L, a and b value of softened sea tangle during storage was relatively decreased. Color preference, odor, cohesiveness, softerness, process compatibility were revealed to be in best when isomalto oligosaccharide was added. When softening agent was added to the softened sea tangle it showed the positive result in processing compatibility and the available value in intermediate material for its processing product. It was relatively effective on softening stability when isomalto oligosaccharide was added to the softened sea tangle.
