To improve the food quality of traditional Jeung-pyun(Korean fermenfed rice cake), effect of mixed ingredients on the quality of protein enriched product was studied. Changes were evaluated in chemical and textural properties of protein enriched Jeung-pyun altered by fermentation time, temperature, and steaming time. The maximum volume wxpansion was noted in dough mixed with rice flour(100 g), soy flour(25 g), sucrose(20 g), Tak-ju(50 ml) and water(10 ml), and then fermented at $35^{\circ}C$ for 3 hours. Soy protein isolate(SPI) enriched rice dough had a maximum expanded volume when 15g(w/w) of SPI, 20g(w/w) of sucrose, 60ml(v/w) of Tak-ju and 50ml(v/w) of water added into 100g rice flour, and then fermented at $30^{\circ}C$ for 2 hours. Steaming after fermentation made the smaller volume of bulk $45^{\circ}C$-50% of the initial volume be showed just after fermentation. Protein enriched Jeung-pyun prepared under the maximal volume endowing conditions showed the best protein quality(protein digestibility and protein efficiency ratio) and starch structure which was susceptible towards enzyme reaction. The improved starch quality of protein enriched Jeung-pyun could be confirmed by reducing power, gelatinization degree and amylose content. Jeung-pyun riched with soy flour at 20% level or with SPI at 5% showed the best overall quality by sensory and textural property but it had a problem in browning.
