| Abstract | The immune system plays a crucial role in protecting the body against pathogens and free radicals that can cause cellular damage. Purple sweet potato (Ipomoea batatas L.) is a source of anthocyanins with potential for development into nutraceutical products. Gummy candies is a practical nutraceutical dosage form that is popular with the public. This study is aimed to formulate purple sweet potato gummy candies, investigate the effect of varying gelatin concentrations on physical and organoleptic characteristics and determine the optimal gelatin concentration. This experimental study involved three formulas based on varying gelatin concentrations: F1 (7%), F2 (12%), and F3 (17%). Evaluations included organoleptic tests, weight uniformity, moisture content, pH, elasticity, stability and hedonic testing. Hedonic test data were analyzed using the Friedman test at a 95% confidence level. The results showed that all formulas were uniform in shape, purple in color, had a characteristic grape aroma and possessed a chewy texture; they also met the requirements for weight uniformity, moisture content and pH. Increasing the gelatin concentration resulted in higher moisture content and elasticity. All formulas remained stable during 14 days of storage at cold temperatures (2–8°C), whereas fungal growth occurred at room temperature (25±2°C). Variations in gelatin concentration significantly affected preference levels for aroma, taste and texture (p<0.05) but did not significantly affect color (p>0.05). Formula F2 (12%) was identified as the optimal formula because it met physical evaluation requirements and achieved the highest preference ratings, particularly regarding taste and texture.
