ANTIOXIDANT ACTIVITY, TANNIN CONTENT AND DIETARY FIBER FROM COFFEE HUSK EXTRACT AND POTENTIAL FOR NUTRACEUTICAL

Abstract

The coffee processing industry still produces a lot of solid waste that has not been utilized optimally. The use of coffee husk waste is only as animal feed and fertilizer. While, the compound content in coffee husk waste contains high-fiber and it is indicated to be used as an antioxidant, antimicrobial, anti-allergic, and anti-hypertensive. The sample of coffee husk waste was mashed into a homogeneous powder then the analysis was carried out using volumetric, gravimetric, and UV-Vis spectrophotometry methods. Here, we report the antioxidant activity, tannin content, total dietary fiber and potential nutraceutical from the coffee husk. Antioxidant activity of coffee husk was very strong (IC 50 = 20 ppm) and tannin content was 10%. Hence, the coffee husk can be potential as raw material for making nutraceutical that used for the treatment of diseases caused by free radical exposure. The total dietary fiber of coffee husk was obtained by 34%. Thus, coffee husk waste also can be utilized as the prevention of digestive diseases.
