Enzyme-Assisted Extraction of Polyphenols From Rose (Rosa Damascena Mill.) Petals
Abstract
: The efficiency of enzyme-assisted extraction for the recovery of polyphenols from rose (Rosa damascena Mill.) petals was evaluated performing a simplex centroid experimental design for mixture with three components (pectinolytic, cellulolytic and hemicellulolytic preparation). The ternary enzyme combinations leaded to the highest contents of total polyphenols, reaching 43% higher average value as compared to the control (without enzymatic treatment) sample. Enzymatic treatments also enhanced (9−25%) the extractability of total anthocyanins. The results obtained demonstrate that enzyme-assisted extraction improves the recovery of polyphenolic antioxidants from rose petals, especially using ternary enzyme combinations, comprising pectinolytic, cellulolytic and hemicellulolytic preparation.
