Abstract
|
|
|
|
To promote the consumption of mulberry fruit, we manufactured mulberry fruit wine with 'simheung' by different processing methods and analyzed cyanidin-3-glucoside(C3G) stability and antioxidant capacity. In the processing of mulberry fruit alcoholic drink, 3 minutes blanching using microwave inhibited the C3G destruction by maintaining the antioxidant capacity and inactivation of enzymes related to pigment's stability. And freeze-dried mulberry fruit was the highest C3G pigment content and antioxidant capacity. Nevertheless, this is not recommended because the economic burden of the cost of freeze-drying. In conclusion, when processing mulberry fruit wine, the addition of citric acid and the enzyme's inactivation treatment were considered more effective than storage containers (transparent glass, brown glass bottles, aluminum foil, green glass, translucent glass bottles).
