Karakteristik Mutu Sirup Buah Dengan Penggunaan Sari Buah Kelubi Dengan Gula Fruktosa Dan Sari Labu Kuning Sebagai Pewarna
ABSTRACT
The sour-tasting kelubi fruit and the sweet-tasting fructose sugar can be combined to make syrup, a thick, high-sugar beverage product that also contains natural pumpkin pigment. The purpose of this research was to obtain the best concentration of kelubi fruit juice and fructose sugar in making kelubi fruit syrup. This research was conducted experimentally using a completely randomized design (CRD) with four treatments and four replications. The treatments in this study were GB1: 50% fructose sugar with 50% kelubi fruit juice (w/v), GB2: 60% fructose sugar with 40% kelubi fruit juice (w/v), GB3: 70% fructose sugar with 30% kelubi fruit juice (w/v), and GB4: 80% fructose sugar with 20% kelubi fruit juice (w/v). Data obtained were statically analyzed using analysis of variance (ANOVA) and continued with Duncan’s Multiple Range Test (DMRT) at the 5% level. Based on the research, the data showed that the ratio of fructose sugar and kelubi fruit juice significantly affected the values of pH, reducing sugar content, viscosity and sensory. The best treatment in this research was GB2 (60% fructose sugar with 40% kelubi fruit juice (w/v)), which yielded a pH of 3.16, a reducing sugar content of 13.80%, and a viscosity of 516.07 cP. The descriptive assessment revealed that the syrup had a yellow color, a kelubi scent, a sweet and sour taste and a thick consistency. Hedonic sensory assessments of color, scent, taste, consistency, and overall attributes were preferred by the panelists.
