Quality characteristics of tomato jam added with 15, 25, 35 and 50% fructo-oligosaccharide substituted for sucrose were evaluated. As the amount of fructo-oligosaccharide increased, the moisture content and total titratable acidity of tomato jam increased, whereas pH and spreadness decreased. In the results of color and texture analysis, lightness (L*), redness (a*) and yellowness (b*) in addition to adhesiveness and resilience increased when fructo-oligosaccharide was added up to 50% of the total tomato weight. In the sensory evaluation, values of flavor, transparency, sweetness, and off-flavor decreased as fructo-oligosaccharide content increased, whereas tomato flavor, sourness and stickiness increased. Overall acceptance of tomato jam added with 25~35% fructo-oligosaccharide was the highest among all of the samples.
