The purpose of this study was to investigate the sensory and physicochemical attributes of Cham-chwi dduk with various amounts of Cham-chwi(Aster scaber) and salt. Cham-chwi dduk was made by steaming glutinous rice flour with Cham-chwi powder for 15 min. Cham-chwi powder was added 1, 3, 5% of glutinous rice flour weight and salt was added 0.5, 1.0 1.5%. According to the sensory evaluation, bitterness and Cham-chwi flavor increased as the amount of Cham-chwi increased and saltiness increased as the amount of salt increased(p<0.05). In the textural profiles, chewiness, adhesiveness, hardness and gumminess were highest when 3% Cham-chwi was added. The moisture content of Cham-chwi dduk was increased as the amount of Cham-chwi was increased and the amount of salt was decreased. The more amount of added Cham-chwi increase, the more green color was strong and yellow color was weak. These results were used to determine the optimum conditions of adding levels of Cham-chwi and salt. Conditions were standardized with minimum range of firmness when expected value of Cham-chwi flavor was more than six and expected value of bitterness was less five. The optimum conditions of Cham-chwi dduk was established as the 3.1% Cham-chwi and 0.6% salt.
