CONTENT • Introduction • Extraction using a solvent • Supercritical extraction • Extraction assisted by enzyme
LYCOPENE • Type of carotenoid • Aditive, colorant and antioxidant • Tomatopomace • Ripetomatoes
CONTENT • Introduction • Extraction using a solvent • Supercritical extraction • Extraction assisted by enzyme
EXTRACTION USING A SOLVENT • Fat-soluble: extractedwith organic solvents • Raw material: tomato waste skin • Solvent: hexane:acetone:alcohol (2:1:1) + BHT. • Variables
EXTRACTION USING A SOLVENT VARIABLES Number of extraction Solvent/meal ratio Solvent/mealratio Particlesize
EXTRACTION USING A SOLVENT VARIABLES Temperature Number of extractions Particlesize Number of extractions
EXTRACTION USING A SOLVENT VARIABLES Extractiontime Number of extractions
EXTRACTION USING A SOLVENT OPTIMUS CONDITIONS solvent/meal: 30:1 v/w 4 extractions 50 °C particle size 0.15 mm extraction time 8 min. Lycopene yield: 1.99 mg/100 g
CONTENT • Introduction • Extraction using a solvent • Supercritical extraction • Extraction assisted by enzyme
SUPERCRITICAL • Supercritical fluid extraction (SFE) • Tc, Pcsolvent • CO2: • low critical temperature, • not toxic, • not flammable, • low cost , • high purity
SUPERCRITICAL • Semi-continuos process • Equipment: an extractor, a back pressure regulator, a chiller, a high pump for CO2, collection vials and a wet gas meter. • Optimization: tomato seed oil (co-solvent)
