The Quality Characteristics of Sulgidduk with Added with Burchu (Allium tuberosum R.) Powder during Storage

부추가루 첨가 설기떡의 저장 기간 중 품질 특성

The purpose of the study was to perform research a proximate analyses and sensory evaluations for sulgidduk over a storage period, where the sulgidduk contained added with buchu powder added at 1%, 2%, and 3% concentrations. The general composition of the buchu powder was 34% crude protein, 1.8% crude lipid, and 21.8% crude fiber while the moisture contents of the buchu powder was 2.71%. The moisture contents of the sulgidduk samples over the storage period ranged from 34% to 38%. Color and moisture changes were not significant (p<0.05) during storage, while the values showed significant decreasing trends (p<0.05) with greater additions of buchu powder. In terms of textural characteristics, hardness, cohesiveness, gumminess, and chewiness decreased significantly (p<0.05) with greater concentrations of buchu power, while adhesiveness and springiness showed no significant differences(p<0.05). Based on the sensory evaluations, overall preference was high for the 3% buchu powder sample. This sample received high scores on flavor, color, taste, chewniess, and moisture, suggesting that adding 3% buchu powder would be feasible for making sulgidduk.
