Maimulyanti, Askal; Prihadi, Anton Restu published the artcile< Integrated extraction by percolation, distillation, and soxhlet extraction to separate bioactive and bioenergy compounds from spent coffee ground>, Recommanded Product: (9Z,12Z)-Methyl octadeca-9,12-dienoate, the main research area is coffee ground caffeine chlorogenic acid percolation distillation soxhlet extraction.
The spent coffee ground has potential compounds applied in food and bioenergy. In this study, an integrated extraction to sep. chem. compounds from the spent coffee ground was designed. Furthermore, the extraction apparatus was combined for percolation, distillation, and Soxhlet extraction The distillation technique produces flavored coffee, Soxhlet extraction separates coffee oil; while percolation produces the coffee extract Anal. of coffee aroma using distillation techniques obtained alpha furfuryl alc. (52.16%), Me pyrazine (15.63%), and 2.6-di-Me paradiazine (9.62%). Anal. of coffee extract using the percolation technique obtained antioxidant compounds with IC50 (56.61μg/mL), polyphenols (1.25 mg/g), caffeine (7.88%), chlorogenic acid (1.25%), and tannins (21.22%). Anal. of coffee oil using the Soxhlet extraction technique obtained Me ester compounds that have the potential for biodiesel such as linoleic acid Me ester (39.90%), palmitic acid Me ester (34.30%), oleic acid Me ester (8.74%), and stearic acid Me ester (8.66%). The integrated extraction has successfully separated many chem. components from spent coffee ground dan it has added value to be applied in food, beverage, pharmaceutical, and bioenergy.
