Abstract
The spices used in this research were ginger, galangal, lemongrass, pandan and cinnamon. This spice has advantages, including being able to improve the aroma and taste of instant spice coffee and having antioxidant activity which is good for health. Making instant drinks can be done using the crystallization method. The addition of sugar in crystallization process acts as a crystallizing agent, sweetener and preservative. The aim of this research is to analyze the effect of the proportion of ginger extract and spice extract and the addition of sugar on the characteristics of instant spiced coffee, as well as determine the best formulation that produces instant spiced coffee with the best quality. This research used a completely randomized design (CRD) with a factorial pattern with two factors and two replications. Factor I is the proportion of ginger extract: spice extract (2:8, 3:7, and 4:6) and factor II is the addition of sugar (25%, 35%, and 45%). Data were analyzed using Analysis of Variance (ANOVA) and the Duncan Multiple Range Test (DMRT) at the 5% level. The results of the research with the best treatment were obtained from a combination treatment with a proportion of ginger extract and spice extract of 3:7 with the addition of 45% sugar to produce instant spiced coffee with a yield value of 39.14%, water content 1.43%, ash content 1.40%, solubility 89.47%, dissolution rate 0.12g/s, total dissolved solids 17.25%brix, antioxidant activity 87.36%, total phenol 15.90 mgGAE/g, and organoleptic tests including color 4.20 (like), aroma 4.08 (like), taste 3.72 (neutral), and overall likeability 3.92 (neutral).
