| Research Abstract |
It is a very important problem in an aging society that the development of eatable foods for old persons should be taken place. As gels need not to be bitten and are easy to add various nutrients at cooking and proceeding process, gels are suitable for food of sick persons, babies and old persons. Mixed gels, which an old person can easily bite, were measured by the objective and subjective methods of dynamics. Gellan gum, which forms thermostable gel, was used in order to take calcium, and dietary fiber. Soybean dietary fiber (SDF) and polydextrose were used as dietary fiber and milk powder was used as a source of supply for calcium. Gellan gum jellies with SDF increased thermostable and decreased rupture strain with increasing the concentration of SDF,and rupture stress increased up to a certain concentration of SDF.Gellan gum jellies with SDF containing CaCl_2 was favored. In gellan gum jellies with polydextrose, storage modulus and rupture property values did not changed remarkably with increasing the concentration of polydextrose. The jellies with high concentration of polydextrose was favored. The data of jellies with milk powder were analyzed by use of the modification of Scheffe's mixture experiment method in rectanglar experimental area in the Scheffe's triangle, and softer jellies were judged smoother than harder jellies. From above result, gellan gum jellies with SDF,polydextrose or milk powder seemed to be hopeful and useful foods for the old persons to take dietary fiber and calcium.
