Quality Characteristics of Pound Cakes Prepared with Flowering Cherry (Prunus serrulata L. var. spontanea Max. wils.) Fruit Powder during Storage

摘要

The study investigated the quality of pound cake prepared with various concentrations of cherry powder (obtained from ground fruit of Prunus serrulata L. var. spontanea Max. wils.). Pound cake was evaluated for their sensory property and physical quality stored for 10 days at 25°C. The pH of the batter decreased with rising cherry powder concentration. The specific loaf volume and height decreased (from 2.95 to 2.60 cm3/g) with increasing in cherry powder. The baking loss rate of the pound cake tended to increased by 11.47-12.67%, but with no significant differences. The lightness, redness, and yellowness values were significantly decreased with increases in cherry powder except for redness of pound cake crumb. As the concentration of cherry powderincreased, the mechanical characteristics of the pound cake did not differ significantly. The hardness tended to increase, while adhesiveness and springiness decreased with increases in powder. The retrogradation degree of pound cake prepared with cherry powder was higher than the control but there were no significant differences. For the antioxidative activity measured by DPPH (2,2-diphenyl-l-picrylhydrazyl) radical scavenging activity, pound cake prepared with 10% and 15% added cherry powder showed high antioxidant activities. The pound cakes containing 10 and 15% cherry powder had acceptable sensory properties, such as flavor, taste, softness, moisture, and overall acceptability. The results exhibited that adding the cherry powder into the pound cake increased antioxidant activity with the highest quality improvement obtained by incorporating 10% (w/w) of cherry powder into the pound cake formula.
