Abstract

Dragon fruit is known for its numerous health benefits. These benefits include slowing premature aging, preventing cancer, boosting immunity, increasing appetite, lowering cholesterol, strengthening bones and teeth, preventing diabetes, promoting eye health, maintaining heart health, and promoting healthy skin.This study was conducted to determine the effect of the type and concentration of thickening agent on the viscosity of red dragon fruit jam (Hylocereus polyrhizus). This study used a Randomized Experimental Design (RAK) in a Split Plot Design (RPT) with 2 factors, namely: the type of thickening agent (pectin, CMC, agar-agar) and its concentration (0.5%; 0.1%; 1.5%), which was continued with the Least Significant Difference (LSD) test if the treatment had a significant effect. The parameters analyzed were pH, water content, viscosity and organoleptic tests (aroma, taste, color, and viscosity).The results of the study showed that the best treatment for red dragon fruit jam was obtained by adding a thickener of CMC (Carboxyl Methyl Cellulose) with a concentration of 1% which resulted in a water content of 41.09%, a viscosity value of 54 Poise and an average hedonic test value of 4.04.
