Abstract

The purpose of this study was to investigate optimal condition for making marinated crabs sauce added mulberry branches(M/B), which is effective in removing smells and storing food with antibacterial function of microorganism, and present the biochemical properties, VBN, changes of microorganisms and amino acids, and sensory evaluations. pH increased along with aging process when the same amount of M/B. After 1 day of aging, salinity decreased significantly along with the added amount of M/B(p<0.001). Sweetness decreased along with the aging process. L-value decreased as the aging proceeded, so the color turned darker. a-value and b-value showed significantly high figures with 1 day aging and G4(p<0.05). VBN of G4 was lower than that of other groups, meaning the lowest level of decomposition. The samples with M/B showed lower number of microorganism than the G1 due to antibacterial function(p<0.05). Total free amino acid content was the highest in G5 and it increased along with aging process. Characteristic difference test results showed bitterness, grass flavor, and astringent flavor increased significantly as the amount of M/B increased(p<0.05). Savory taste was the highest (p<0.001). Fish flavor was the highest in the G1 and it decreased as the amount of M/B increased(p<0.001). In the preference test conducted on general consumers, flavor, taste, and general preference was statistically significant(p<0.01).

본 연구의 목적은 비린 냄새 제거와 미생물 항균작용으로 저장성 향상 효과가 있는 참뽕가지를 어간장게장 제조에 이용하고자 이화학적 특성, VBN, 미생물 변화 및 아미노산 변화, 관능적 품질 특성을 평가하여 첨가량과 최적조건을 제시하는 것이다. pH는 숙성 1일과 5일 각 시료 간에 유의한 차이를 보였으며(p<0.001), 참뽕가지를 동일한 양으로 첨가하였을 경우, 숙성 기간에 따라 증가하였다. 염도는 숙성 1일에서 대조구보다 참뽕가지의 첨가량이 증가할수록 유의하게 낮아졌다(p<0.001). 당도는 숙성시간이 증가함에 따라 낮아졌다. L-value는 같은 양의 참뽕가지를 첨가하였을 때 숙성기간이 늘어날수록 값이 감소하여 색이 어두워졌다. a-value와 b-value는 숙성기간 1일, 참뽕가지 함량 100 g일 때 유의적(p<0.05)으로 높은 값을 나타내었다. VBN 함량은 숙성기간 1일과 5일에서 G4에서 가장 낮은 VBN 함량을 나타내어 부패도가 가장 낮았으며, 미생물 수는 숙성 1일에 대조구가 가장 높았고, 참뽕가지 첨가량이 증가할수록 항균작용을 하여 대조구보다 낮게 나타났다(p<0.05). 총유리아미노산은 숙성기간이 지남에 따라 증가하는 경향을 나타내었다. 특성차이검사 결과는 쓴맛, 풀 냄새, 텁텁한 맛이 참뽕가지 첨가량이 증가할수록 유의적(p<0.05)으로 진하다고 평가되었다. 감칠맛은 G4가 가장 높게 평가되었고, 참뽕가지를 첨가한 모든 시료가 대조구에 비하여 유의적(p<0.001)으로 구수하다고 평가되었다. 비린내는 참뽕가지를 첨가하지 않은 대조구에서 가장 높았으며, 첨가량이 증가할수록 감소한다고 평가되었다(p<0.001). 일반소비자들에 대한 기호도 검사결과, 향, 맛, 전반적인 기호도는 통계적으로 유의한 것으로 나타났다(p<0.01).
