In this study, the sensory characteristics of various fruit(pineapple, orange, grape, strawberry, kiwi, apple and banana) demi-glace sauces were compared. The viscosity of banana sauce was higher than the controls (7.03). Additionally, the sensory characteristics of other fruit sauces were lower than those of the controls, and additionally the viscosity as significantly different from the controls. The pH values of the fruit sauces were lower than the control values (4.40), and the brix of the fruit sauces was higher than that of he controls. The L-values of the controls (22.69) were higher than those of the banana sauce (25.20), and orange sauces (23.15). The a-values of the demi-glace sauce were higher than those of the fruit sauces. The b-values of the 8 types of demi-glace sauce ranged from 6.92 to 14.31. In the sensory evaluation of overall acceptability, the demi-glace sauce, kiwi sauce, orange sauce, and grape sauce achieved the highest scores. with regard to the overall acceptability of tofu steak with turmeric and fruit sauces, the kiwi sauce, pineapple sauce, and apple sauces achieved the highest scores.
