The parameters analyzed were total sugar value, crude fiber content, viscosity, pH value, vitamin C content, antioxidant activity, total microbes, taste score, aroma score, color score, texture score, hedonic value of general acceptance. The results showed that the addition of kasturi orange juice to jelly drinks brown rice bran extract had a significantly different effect (P0.05) on taste score, aroma score, color score and hedonic value of general acceptance. The interaction of kasturi orange juice addition to brown rice bran extract and konyaku flour gave a significantly different effect (P<0.01) on the total sugar value, crude fiber content, viscosity, pH value, vitamin C content, antioxidant activity, total microbes, taste score value, aroma score value, color score value, texture score value, hedonic value. Meanwhile, the addition of konyaku flour had a significantly different effect (P<0.01) on the total sugar value, crude fiber content, viscosity, pH value, vitamin C content, antioxidant activity, total microbes, and texture score. The effect was not significant (P>0.05) on taste score, aroma score, color score and hedonic value of general acceptance.
