Resumen:
Ultrafiltration, (NH)rSOoaddition to 80% saturation and lyophilization after desalting, were assessed as different methods for the concentration of tomato fruit a- and B-galactosidases and s-L-arabinofuranosidase. Lyophilization was the most effective giving 95%,82% and 75%o recovery of enzyme activities, respectively. These enzymes are stable when preserved after lyophilization or in concentrated crude extracts at 20 or 50°C even after extended storage, either in the presence or absence of trehalose.
