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. This study involved multiple reactions and reactants, such as Methyl nonadecanoate (cas: 1731-94-8Related Products of 1731-94-8).
Methyl nonadecanoate (cas: 1731-94-8) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Related Products of 1731-94-8
