A Study on the Characteristics of Mandu-pi Differing in Roasted Soy Flour Content

볶은 콩가루 첨가를 달리한 만두피의 특성 연구

The purpose of this study was to investigate the effect of roasted soy f1our on the characteristics of Mandu-pi. Various Mandu-pi samples were prepared with wheat flour along with the addition of different amount of roasted soy flour. and then instrumental characteristics and sensory evacuation were investigated. As a result of amylography study, there were no difference In the initial pasting and maximum viscosity temperatures between samples. And maximum viscosity decreased with the increase of flour addition. In farinography study, the addition of roasted sop f1our did not affect the gelatinization temperature, while stability and developing time of dough increased by addition of soy flour level. Besides cooked weight, cooked volume and water absorption of Mandu-pi were also higher significantly than control. The more soy flour was added, the less lightness and more redness and yellowness were obtained. The result of sensory evaluation revealer that there were no differences between samples in beano aroma, smoothness, and chewness. However Mandu-pi added roasted soy flour showed higher scores in surface appreance, nutty aroma, nutty taste. sweet taste, and overall preferance than control.
