Abstract

|
This study was conducted to determine whether Diospyros lotus L. fruit could be used as a natural functional food ingredient and whether its use should be increased. D. lotus fruit powder was found to have high acidity in the immature IDL stage and significantly higher sugar content in the mature MDL stage. The levels of crude fat, selenium, and tannins decreased significantly from the IDL stage to the MDL stage in D. lotus fruit powder. However, the levels of magnesium and calcium were significantly greater in the MDL stage than in the IDL stage (p<0.05). The total phenol content was significantly higher in the IDL stage, but the DPPH radical scavenging activity significantly increased in the MDL stage (p<0.05). In conclusion, the fruits of D. lotus. have high nutritional quality in both the immature and mature growth stages. Thus, it is a good candidate for use as a functional food, and its use should be increased because of its high nutritional qualities.
