Effects of enzymatic extraction on anthocyanins yield of saffron tepals (Croc…

An aqueous solution of Pectinex (containing cellulase, hemicellulase, and pectinase) at 1%,2.5%, 5%, 7%, and 10% concentrations and 40 C was used to extract anthocyanins (Acys) of saffron tepals at 20, 40, 60, 120 and 180 min reaction times and compared with ethanol solvent under similar conditions. The Acys of the Pectinex solution reached 6.7 mg/g of tepal powder (~40% more than the ethanol m…
