As a trial to expand the use of oligosaccharide, tomato jams were made with various kinds and addition rate levels of oligosaccharide and their quality characteristics were evaluated by instrumental analyses and sensory evaluation. As the addition rate of oligosaccharides increased, 1. the sweetness of tomato jams decreased compared to those of control containing sugar, 2. the lightness and yellowness were increased, however, the redness was decreased, 3. the hardness and adhesiveness of tomato jams containing liquid type oligosacchairdes were lower and those of powder type were higher than control. The springiness of the samples containing oligosaccharide was lower than that of control, however, there was no significant difference in cohesiveness. In sensory evaluation, tomato jams containing oligosaccharides were generally similar or better than control. Color, viscosity, flavor and overall acceptability of the samples containing powder type oligosaccharide were higher than those of liquid type. Tomato jams containing 15% powder type oligosaccharide and 35% sugar showed the highest overall acceptability.
