Abstract

This study aimed to determine the RH of the process enzymatic oxidation room on the cascara characteristics of arabica and robusta coffee husks. This study used a factorial completely randomized design (RALF) with two treatment factors, namely the types of coffee (arabic, and robusta) and room RH (80%, 85%, 90%, 95%). Each treatment was repeated three times. The parameters observed included physical characteristics (color), phytochemical contents (alkaloids, flavonoids, saponins, and tannins), and chemical characteristics (antioxidant activity, water solubility index, total acid, total phenol, and pH). The results of this study show that the type of robusta coffee husk has no significant effect on the pH value of cascara, but cascara from robusta coffee husk produces a higher pH value than Arabica coffee husk. The type of Arabica coffee rind had no significant effect on the value of antioxidant activity, water solubility index, total acid and total phenol in cascara, cascara from Arabica coffee rind resulted in higher antioxidant activity values, water solubility index, total acid, and total phenol compared to coffee rind. robusta. Enzymatic oxidation of coffee skin at room RH has a significant effect on the value of color (lightness (L*), yellowness (b*), and pH, the higher the RH used in the enzymatic oxidation process, the higher the value of lightness, yellowness and pH. Cascara from the skin Arabica and Robusta coffee in all room RH enzymatic oxidation processes contained alkaloids, flavonoids, saponins and tannins.The best treatment was enzymatic oxidation process with 95% RH with Arabica coffee husk.
