본 연구는 빙점 강하제를 첨가한 다진 홍고추의 활용 가능성을 평가하기 위해 김치에 첨가하여 특성변화를 살펴보았다. 빙점강하제로는 NaCl, glucose, pectin, ascorbic acid를 사용하였으며 비율을 달리하여 다진 홍고추에 첨가한 후 김치를 제조하여 관능평가를 한 결과 관능에 가장 큰 영향을 미치는 요인은 NaCl 함량임을 확인하였다. 이에 glucose, pectin, ascorbic acid 함량은 각각 5%, 1% 및 0.5
We investigated the use of mashed red pepper in the manufacture of kimchi using various freezing point depression agents (glucose, pectin, ascorbic acid or NaCl). In sensory evaluation results, overall acceptance seemed to be highly related to NaCl content. Kimchi was prepared using mashed red pepper with different levels of NaCl (3, 5, and 10% w/w), and quality characteristics were investigated during storage at . Salt concentrations of kimchi prepared with addition of 3, 5, or 10% NaCl, and control kimchi, were 2.28, 2.47, 3.10 and 1.92%, respectively. pH values varied significantly among treatments but acidity levels did not differ significantly except during the early stages of production. With increasing NaCl addition, the acidity of kimchi was lower than that of control samples during later fermentation periods. At day 20, the reducing sugar level in control kimchi had decreased by 70% whereas NaCl treatment caused decreases of 45 - 55%. The vitamin C contents of kimchi prepared with addition of NaCl (125.88-145.23 mg/100 g) were higher than that of control (37.22 mg/100 g). In sensory evaluation tests, appearance and texture did not differ significantly with treatment or fermentation period. When taste and overall acceptance were scored, kimchi prepared with the addition of 3% NaCl attained the highest marks throughout the entire fermentation period.
