ANALISIS FISIKOMIA DAN SENSORIS SELAI BUAH NAGA MERAH DENGAN PENAMBAHAN KULIT BUAH NAGA MERAH (HYLOCEREUS POLYRHIZUS)

This study aimed to analyze the characteristics of red dragon fruit (Hylocereus polyrhizus) jam with the addition of red dragon fruit peel. The research employed a Completely Randomized Design (CRD) with a single-factor treatment consisting of six levels of red dragon fruit jam formulations: A1 (0% peel addition), A2 (30% peel addition), A3 (40% peel addition), A4 (50% peel addition), A5 (60% peel addition), and A6 (70% peel addition). Each treatment was repeated three times, resulting in a total of 18 experimental units. The observed parameters included physical characteristics (spreadability and color), chemical characteristics (moisture content, ash content, pH, total sugar, antioxidant activity), and sensory characteristics (texture, color, and taste). The results showed that the formulation of red dragon fruit jam with the addition of red dragon fruit peel significantly affected the spreadability, color, water content, ash content, pH, total sugar, and organoleptic tests (texture, color, and taste), but did not significantly affect antioxidant activity. Treatment A3 (addition of 40% red dragon fruit peel) was the best treatment, with the following characteristics: physical properties (spreadability 11,37 cm, lightness 29,44%, redness 13,38%, yellowness -1,01%), chemical properties (moisture content 38,74%, ash content 0,54%, pH 3,48, total sugar 10,20%, antioxidant activity 9.799,35 μg/mL), and sensory characteristics (flavor preference score 3,28, color preference score 3,56, texture preference score 3,68).
