Popis: The aim of this study was to determine the quality of guava jelly after the addition of papaya peel extract and citric acid. The study used a two-factor, randomized factorial design. The first factor was the addition of papaya peel extract (P): (2%;4%;6%;8%), while the second was the addition of citric acid (A): (1%;1,5%;2%;2,5%). The parameters analyzed were moisture content, ash content, total soluble solids, vitamin C content, crude fiber content, degree of acidity (pH), and total acid. According to the results, the addition of papaya peel extract had a highly significant effect on the water content, crude fiber content, degree of acidity, total acid, and had a differ significant effect on ash content and total dissolved solid. The addition of citric acid also had a highly significant effect on the total dissolved solid, the content of Vitamin C, degree of acidity, the organoleptic test of taste, and had a differ significant effect on water content and total acid. The interaction between the addition of papaya peel extract and citric acid had a highly significant effect on the degree of acidity. Guava jelly with 8% papaya peel extract and 2% citric acid had the optimum quality characteristics.
