Abstract
Centrifugal ultrafiltration of genipap fruit extracts after mechanical/sonic enzymatic treatment was performed through 50, 30, 10 and 3 kDa molecular weight cut off (MWCO) (15min; 10°C; 9425g). Volume, volumen retention factor (VRF), flux, genipin and glucose concentrations were determined. Separation efficiency, retention, transmission coefficients (RC,TC), and membrane selectivity were estimated. Reduction in MWCO increased volumen in the retentate (7.670.0 mL), decreased VRF (1.970.0) and flux (0.0670.00 mL cm_2 min_1) after 3 kDa ultrafiltration. Genipin and glucose reached equilibrium in retentate and permeate (1773.3; 1671.5mgmL_1; 4172.2 and4174.8 mgmL_1) after 3 kDa ultrafiltration. The highest removal of genipin was 0.570.1.RC and TC were 0.570.1; selectivity for genipin was 0.970.0 after 3 kDa separation.
