This study analyzed the changes in the nutritional components, properties, physicochemical properties, general bacteria, and lactic acid bacteria of pickled cabbage depending on the cultivation area. An analysis of the nutritional composition on the first day of storage showed no significant difference in the calories, carbohydrates, protein, fat, and dietary fiber contents regardless of the cultivation region, but regional differences were observed in the vitamin C content in the order of Andong > Pyeongchang > Haenam. The total free amino acid content appeared in the order Andong > Pyeongchang > Haenam, and the GABA (-amino-n-butyric acid) content appeared in the order Haenam > Andong > Pyeongchang. In addition, pickled cabbage was observed on the 1st, 5th, and 10th days of storage at 4oC. No significant change in appearance was observed on the 1st and 5th days, but changes were observed on the 10th day. Regardless of the cultivation area, the salinity (p<0.05) and pH (p<0.05) decreased significantly as the storage period increased, while the sugar content (p<0.05) and acidity (p<0.05) increased significantly. The general bacteria (p<0.05) and lactic acid bacteria (p<0.05) counts increased significantly as the storage period increased, irrespective of the cultivation region.

Physicochemical characteristics of vinegar pickled cabbages during storage were examined. 3x3 cm cube-shaped stems and leaves of cabbages examined in different pickling condition (salt 2, 4, 6, 8% and sugar 5, 10, 15, 20% brix) for 12 hours, and salt and sugar penetration rate were measured at every 2 hours. The vinegar pickled cabbages were stored for 4 weeks at 3 different temperature conditions (5, 15, and 25℃), and sensory test and TPA test were performed at intervals of every week. The rates of salt and sugar penetration were faster on the leaves than on the stem of cabbage. Also, increase in salt and sugar concentration of solutions led to increase in salt and sugar permeation rate. As a result of sensory test, both leaves and stems of cabbages stored at 5℃ did not show any significant difference with storage time. However, preference degree of cabbages stored at 15 and 25℃ decreased significantly as increasing the storage time. Hardness and cohesiveness of pickled cabbage were increased significantly as the storage time increased, but storage temperature did not give any effect on them.

연근즙 첨가수준에 따라 백김치를 제조한 후 에서 4주간 저장하면서 숙성 중의 이화학적, 관능적 특성을 조사하였다. 연근즙의 첨가수준이 증가할수록 pH는 감소, 산도는 반대로 증가하는 경향을 보였고 숙성기간 중에도 같은 경향을 보였다. 탁도는 첨가수준이 증가할수록 증가함을 볼 수 있었으며, 숙성 2주까지는 대조군의 비해 첨가군의 경우 탁도가 증가하는 경향을 보였으나 숙성 3주, 4주에서는 약간 더 감소하는 경향을 보였다. 색도 L 값과 a 값은 연

식품 조리 및 제조 가공 시 사용되는 소금은 천일염, 정제염 및 수입산염이 대부분이지만, 아직까지 소금 종류에 따른 식품 제조 시 품질특성에 관한 연구는 미비한 실정이다. 이에 국내산 정제염, 국내산 천일염, 수입산염 등 소금의 종류를 달리하여 제조한 김치를 에서 7일간 발효시키며 품질을 비교, 분석하였다. 이화학적인 특성으로 pH, 산도, 염도를 측정하였고, 미생물학적인 특성으로 총균수와 젖산균수를 분석하였으며, 또한 관능검사를 실시하였다. 실

최근, 저온 장시간 발효된 묵은지에 대한 소비가 증가하고 있다. 본 논문에서는, 저온()에서 46주 동안 발효된 묵은지의 pH, 산도, 유기산, 생균수, 아미노산, polygalacturonase (PG) 활성 등을 분석하였다. 10주 발효한 김치에서는 pH 4.1, 산도 0.99%를 나타낸 반면, 46주 발효한 김치에서는 pH 3.9, 산도 1.29%를 보였다. 한편, 10주에서 46주로 발효 기간이 증가하면서, 젖산, 젖산/초산비, Lacto
