Japanese healthy foods and is representative of all shojin (vegetarian) dishes. Gomatofu,
one of the mixed gels consisting of kudzu (arrowroot) starch and sesame, possesses an extremely unusual textural characteristic which is soft,
smooth, and properties are greatly influenced by preparation, ingredients and roasting conditions of sesame seeds.
Hence there are many kinds of sesame materials which can be used to prepare gomatofu such as white, black, huskless or not and roasted or
unroasted sesame materials, in this study, the effects of these materials on the physical properties of gomatofu were studied. The sample of
Ra-W prepared with unroasted huskless sesame seed had the least hardness, but mouthfeel of this sample were the highest. The samples of
Ro-B and Ro-W prepared with roasted husk (black and white) sesame seed were evaluated to have the best palatability because of their
superior springiness. It was clarified that different kinds of sesame materials affected the forming of structure and physical properties of
gomatofu, because the chemical components were different from varieties of sesame materials.
