ORAL SOLUTION HAVING HIGH SOD ENZYMATIC ACTIVITY AND PREPARATION METHOD THEREFOR

摘要

The invention relates to an oral solution having high SOD enzymatic activity and the preparation method therefor, wherein the method comprises: pressing edible plant raw materials, followed by removing large particles by means of centrifugation (1000-4000 rpm, 0-30 min); subsequently, separating the supernatant using two processes of ultrafiltration (the first separation adopting a tubular membrane with pore size ranging from 60-120 kD; the second accomplished by an spiral-wound membrane with pore size ranging from 8-30 kD), before treated using ultra-high pressure at 200-600 MPa for a period of 1-20 min. After treated by the method of the invention, SOD has been activated with enhanced enzymatic activity up to above 10000 U/ml, which has addressed problems related to low enzymatic activity of SOD in products. The products obtained by the present method are more beneficial to human health.
