Quality of Tteokbokki tteok prepared by adding various concentration of brown rice

The purpose of this study was to investigate the properties of tteok prepared from white (Samkwang) and brown rice (Heugseol, Heugjinju). The moisture and crude protein contents of rice were 14.89~17.15% and 4.79~6.81%, respectively. The crude lipid and crude ash contents of rice were 0.48~2.66% and 0.39~1.60%, respectively. The water binding capacity of Heugjinju (141.97%) was higher than those of other rice flours. As the soaking time increased, water absorption ability was in the order of Samkwang > Heugseol > Heugjinju. Using a rapid visco analyser (RVA), the initial pasting temperature of Heugseol was the highest, and the peak viscosities of Heugseol were higher than those of other rice flours. The quality characteristics of Tteokbokki tteok were assessed after its preparation by adding different amounts of Heugseol and Heugjinju (0, 5, 10, and 20%, w/w) content. The textural properties (hardness), of Heugseol and Heugseol measured using a texture analyzer, were greater than those of the control. Sensory preference tests revealed that 10% Heugseol and, 10% Heugjinju had the highest scores in appearance, color, and overall acceptability. The sensory test results revealed that Tteokbokki tteok prepared by addition of 10% added brown rice was the best.
