摘要：
The aim of this study was to evaluate the effect of red-fleshed dragon fruit (Hylocereus polyrhizus) juice concentration on betacyanin degradation kinetics and sensory acceptance. The samples stored at 4 degrees C were comparatively stable compared to 25 degrees C in terms of betacyanin retention, and yeast and mold growth. The loss of betacyanin in red-fleshed dragon fruit juice and concentrate at 25, 37, and 45 degrees C were of first-order reaction. The drink reconstituted from red-fleshed dragon fruit concentrate showed better acceptability in terms of sweetness, flavor, and overall acceptability. The current study demonstrated improved betacyanin retention and sensory acceptance of red-fleshed dragon fruit juice via juice concentration.
