The study showed test results of Teriyaki sauce produced by apple concentrate instead of sugar in order to reduce the sugar content. We created four batches of soy sauce for testing. The Control batch was normal soy sauce. S1, S2, S3, and S4 were sauces made with different amounts of apple concentrate. The test results for the moisture contents, color value, sugar content, salinity, viscosity, pH and sensory evaluation (QDA, acceptance test) of all the types of sauce are as follows. The moisture contents of the Control was 50.80%, and for S4 was 35.14%. In chromaticity results, the L value of the Control was 10.85 which was the highest compared to samples which were in the range of 8.35~8.55. The value of a and b was highest in S4 and was lowest in Control. The sugar content was 53.53 $^{\circ}Brix$ in the Control, and 43.73 $^{\circ}Brix$ in S1. S1 showed 6.77% salinity, and S4 showed 5.37% salinity. The viscosity of S4 was highest at 60.33 cp, and Control showed the highest pH value of 4.82. The QDA of S4 showed the most intense brown color, which was 5.36. For gloss and soy sauce scent, no significant difference was found between the samples. Control showed a mild apple scent which was 1.45, and S1 showed the saltiest flavor which was 5.18. The sweet flavor for Control was 4.64, and S3 showed the strongest aftertaste from the test. No significant difference of appearance and acceptance was found between samples. S2 showed a scent of 5.09, which was the best. The savory taste of S3 was best, and was worst for S1. S3 showed the best overall interest which was 4.55. According to these results, S3 had the lowest sugar content, at 4%, and therefore had the highest possibility of being produced.
