The aim of this study is to assess the replacement effect of black chokeberry (Aronia melanocarpa) used in red-pepper paste seasoning with vinegar. Red-pepper paste seasoning with aronia and vinegar was prepared by mixing red pepper paste, aronia juice or vinegar, sugar and honey, and then aronia juice (J) was added to 0% (C), 50% (A1) and 100% (A2) by replacing the vinegar. As a result, the brightness of the prepared gochujang was decreased with increasing the level of the aronia juice. Total sugar and salinity of C, A1, and A2 showed a significant increase (p<0.05) in compared with that of aronia juice, 24.42 mg/mL and 1.11%, respectively. Also, pH level showed significantly increase with increasing the content of the juice (p<0.05). However, total acidity was decreased with increasing the level of the juice (p<0.05) and A2 (6.55%) especially was lower than the juice, 8.06%. Meanwhile, the total polyphenols were increased with increasing the content of the juice at gochujang samples (p<0.05) and the polyphenols content of the aronia juice was the highest at all samples (p<0.05). The total anthocyanins were also increased with increasing the level of the juice (p<0.05). Antioxidant activity measured by DPPH and ABTS radical scavenging rate was the highest at the aronia juice (p<0.05). Consequently, the result of antioxidant activity of red-pepper paste seasoning with aronia suggested that aronia can be used as a substitute of vinegar in red-pepper paste seasoning with vinegar.
본 연구는 소금을 된장, 간장 및 고추장으로 대체한 우육포의 품질특성 구명 및 전통장류를 이용한 우육포의 제조가능성을 타진코자 실시하였다. 본 실험에 이용된 원료육은 한우육의 semimembranosus 근육을 이용하여 동일한 염도(15)의 소금(대조구), 된장, 간장 및 고추장을 염지액의 2% 수준으로 첨가시켜 70℃에서 8시간동안 건조하였다. 수분활성도는 0.79-0.88의 범위를 만족하며, 처리구에서 대조구인 소금 첨가구에 비해 높은 수분활성도 값을 나타내었다(p<0.05). 수분함량 또한 22.98-28.87%의 범위를 보였으며, 된장과 간장 첨가구에서 대조구보다 높은 수분함량 값을 나타내었다(p<0.05). 육색 측정 결과, 된장, 간장 및 고추장 첨가구에서 대조군보다 낮은 명도 값을 나타내었고, 적색도는 대조구와 고추장 첨가구에서 된장 및 간장 첨가구에 비해 낮게 나타났다(p<0.05). 전단가 및 조직감 측정 결과, 대조구에 비해 처리구에서 낮은 전단가를 보였다. 경도 또한 대조구인 소금 첨가구에서 처리구에 비해 높게 나타났다(p<0.05). 관능평가 결과, 소금을 첨가한 대조구가 6.25로 가장 높은 염도 값을 나타내어 전통장류로 대체 시 소비자들이 느끼는 염도를 줄일 수 있을 것으로 판단된다. 또한 향 및 조직감에서 간장 첨가구에서 가장 높은 값을 획득하였다(p<0.05). 이러한 결과는 종합적 기호도로 이어져 간장을 첨가한 육포가 소금과 된장 및 고추장을 첨가한 육포에 비해 유의적으로 높은 선호도 값을 획득하였다(p<0.05).
Consumption and general views of housewives in Inchon on commercial kochujang(fermented red pepper-soy paste) were surveyed by questionnaires in June through August, 1997. Respondents considered the taste (88.1%) as the most important factors to determine the quality of kochujang and preferred hot(621%) and bright red colored kochujang(70.6%) with fine red pepper powder Eighty seven percent of respondents preferred the traditional kochujang to the commercial one mainly due to the taste and the reliability to the materials kochujang. Especially all housewives at the age of sixty and over preferred traditional kochujang and those at twenties had a higher preferrence for the commercial one compared to other age groups. While 51.4% of the respondents consumed both e traditional and commercial kochujang, 16.2% and 32.5% did only commercial and traditional kochujang, respectively. Consumption of commercial kochujang decreased with age and main food with it was pan fried dishes(33.7%). Convenience(76.6%) was the major reason for purchasing commercial fried and most respondents(44.1%) selected the special brand from the previous experience of their own. Problems to be improved in commercial kochujang were better taste(31.3%) and development of diverse usage(62.4%).
