Abstract
Objective: This research were undertaken to search new alternative of drying method of noni fruit extract that maintain antioxidant properties and activity. Methods: In this research, noni fruit extract were dried with both synthetic drying agent and natural fiber that, respectively synthetic amorphous silica (SAS) and wheat fiber. Each of ethanolic extract and dried extracts were determined for antioxidant activity, antioxidant properties levels, and antioxidant properties release. Antioxidant activity were represented as 2,2-diphenyl-1-picrylhydrazyl free radical scavenging activity while antioxidant properties levels were analyzed by Folin-Ciocalteu method for total phenolic content measurement. Results: Noni fruit dried extract with SAS and wheat fiber showed no significant difference on total phenolic content compared with ethanolic extract (respectively 0.2787±0.0116; 0.2823±0.0100 and 0.2935±0.0048 %w/w GAE). But, only wheat fiber dried extract showed no significant difference on EC50 values towards ethanolic extract (respectively 2682.6257±34.8739 and 2626.4397±48.5153 μg/ml). Wheat fiber and cellulose dried extract showed highest phenolic content respectively after 60 min and 45 min, whereas SAS dried extract couldn’t be determined because its fluctuating release profile Conclusion: Addition of wheat fiber as drying agent could be an alternative for noni fruit extract drying because it had no effect on antioxidant properties levels and activity.
