Iii Symposium on Agricultural and Agroindustrial Waste Management March 12-14, 2013-sao Pedro, Sp, Brazil Bioactive Compounds of Spent Coffee Grounds, a Coffee Industrial Residue
Spent coffee grounds (SCG) are the main residues from the soluble coffee industry. The objective of this work was to evaluate different extraction methods of oil and diterpenes (kahweol and cafestol) from SCG, such as solid-liquid extraction, supercritical extraction or direct saponification, as well as to determine the phenolic composition and antioxidant capacities SCG and defatted SCG. Among...
متن کاملEffects of cafestol and kahweol from coffee grounds on serum lipids and serum liver enzymes in humans.
The diterpenes cafestol and kahweol are present in unfiltered coffee in oil droplets and floating fines. They elevate serum cholesterol and alanine aminotransferase (ALT). We measured fines in coffee brews, and examined diterpene availability from spent grounds in healthy volunteers. Turkish or Scandinavian boiled coffee contained 2-5 g fines/L and French press coffee contained 1.5 g fines/L. A...
