Abstract

The objective of this study was to determine whether sea cucumber flakes could be used in Gochujang. When the concentration of sea cucumber flakes added to Gochujang was increased from 0 to 3% or 5%, moisture content of sea cucumber flakes Gochujang was decreased from 44.13% to 5.52 or 5.58, respectively, although the difference in pH value between the 3% and 5% group was not statistically significant. Titratable acidity did not change with the addition of sea cucumber flakes. When the concentration of sea cucumber flakes added to Gochujang was increased from 0 to 3% or 5%, salinity of sea cucumber Gochujang was decreased from 8.83% to 7.92% or 7.42%, respectively. Amino-type nitrogen content was increased with the addition of sea cucumber flakes. However, the increase was not statistically significant. With increasing concentration of sea cucumber flakes added to Gochujang, color value a* was decreased from 13.82 to 12.25 and 11.14, respectively. Sensory results showed that color, flavor, test, and overall acceptance of Gochujang were all improved after the addition of sea cucumber flakes. There was no significance in color, flavor, test, or overall acceptance between the 3% and the 5% concentration groups of sea cucumber Gochujang.

본 연구는 해삼의 가공활용도를 높일 목적으로 제조한 해삼플레이크를 위리 전통식품인 고추장에 적용하여 그 활용가능성을 확인하고자 하였다. 고추장의 수분함량은 플레이크 첨가량이 0%인 경우에 비해 각각 39.37(3%), 38.01%(5%)로 감소하였다. pH는 해삼플레이크 첨가량에 따라 pH 5.52(3%), pH5.58%(5%)로 증가하였으나 실험군 간 유의한 차이는 없었다. 총산은 각각 3.38(0%), 3.55(3%), 3.56(5%)로 변화가 없었다. 고추장의 염도는 해삼플레이크 첨가량이 0, 3, 5%로 증가함에 따라 각각 8.83%, 7.92%, 7.42%로 감소하였다. 아미노태 질소 값은 196.67(0%), 214.00(3%), 223.00(5%) mg%로 증가하였으나 유의한 차이는 없었다. 고추장의 색도는 해삼플레이크 5% 첨가군의 L*값이 25.16으로 낮았으며, 적색도(a**)는 13.82(0%), 12.25(3%), 11.14(5%)로 감소하였다. 관능평가는 해삼플레이크를 첨가한 고추장이 무첨가 고추장에 비해 높게 평가되었으며, 우리 전통식품에 대한 해삼플레이크의 활용 가능성이 높다고 판단되었다.
