This study was conducted to present primary data for the development of functional beverages by measuring quality characteristics and antioxidant properties and preparing coffee with dried fruit powder. The pH, water content, and brownness were higher in the control group than in the fruit-added sample group. Total polyphenols were highest in the Prunus Fruit Coffee (PFC) at 2765.43±87.03 mg GAE/L. In terms of DPPH, the fruit addition group (consisting of dried apple, dried cherry, and dried plum) was higher than the control group, and the LFC was the highest at 70.04±2.01%. ABTS showed high antioxidant properties in all sample groups, and LFC showed the highest content at 83.01±1.06%. Caffeine was the highest in the control group, all sample groups showed lower content than the control group, and AFC showed the lowest content at 664.70±16.36. As a result, the fruit-added coffee groups are higher than the control groups in terms of quality characteristics and antioxidant properties, and it is considered that the fruit groups are suitable as functional food materials when developing coffee products.
