Abstract

Nutritional composition and antioxidative capacity of mulberry fruit (Ficus-4x) were investigated for evaluation as new red-colored fruit. Contents of moisture, crude fat, crude protein, and vitamin C were similar, whereas that of crude ash was higher, to those of other berry fruits. Contents of minerals (Ca, 14.33 mg/100 g; P, 39.98 mg/100 g; Fe, 6.01 mg/100 g; Zn, 4.04 mg/100 g; Mn, 2.26 mg/100 g), particularly Fe, were higher than those of other berry fruits. Hardness, springness, cohesiveness, gumminess, and chewiness of mulberry fruit were higher, and color values (L, 36.03; a, 1.80; b, 1.54) were lower than those of strawberry. Relative scavenging activities of mulberry fruit methanol extract and its cyanidine 3-glucoside on 1, 1-diphenyl-2-picrylhydrazy radical (DPPH) were 35.7 and 78.2%, respectively, using butylated hydroxyanisole (BHA) as standard. Antioxidant activities in corn oil (peroxide values and conjugated dienoic acid) were tertiary butylhydroquinone (TBHQ) > mulberry fruit ethanol extract > mulberry fruit water extract > butylated hydroxytoluene (BHT) > tocopherol. Results show mulberry fruit can be very useful red-colored fruit for development of functional foods with beneficial effects on radical scavenging and antioxidative capacities.
