초록

첨가 부재료를 달리한 김치를 18℃에서 24시간 예비 발효시킨 후, 4℃에서 35일간 저장하면서 질산염, 아질산염 및 vitamin C의 함량변화를 살펴보았다. 염도가 2.5% 수준인 김치 숙성도를 pH와 산도로 판정해 볼 때, 초기 숙성속도는 새우젓〉멸치, 갓, 마늘〉대조구, 무우〉ascorbic acid〉K-sorbate 순이었고 35일 후 pH 기준으로, 그 숙성도는 대조구〉갓〉무우〉ascorbic acid, 멸치젓〉새우젓〉K-sorbate〉마늘 첨가구 순이었다. 총 vitamin C 함량은 적숙기인 2주에 ascorbic acid 첨가구를 제외한 시료들에서 18.2-26.4 mg%로 담금직후와 같은 수준이었다. 그 중 환원형 ascorbic acid 보존율은 마늘, 갓, K-sorbate 첨가구에서 비교적 좋았다. 질산염, 아질산염의 함량은 숙성초기에 마늘, 무우첨가 김치에서 비교적 높았으며, 숙성기간 중 질산염의 함량범위는 260-490ppm이었고, 숙성 3주째에 최소량을 나타내었으며 이때 아질산염은 검출되지 않았다. 그리고, 총 vitamin C 함량도 이때 가장 낮았다.

This study was intended to observe the changes of the nitrate, nitrite and vitamin C content during the fermentation of Kimchies by some added materials. Eight different types of Kimchi, were prepared with chinese cabbage and seasonings, to which added respectively materials such as soused anchovy, soused shrimp, garlic, mustard leaf, K-sorbate, ascorbic acid, radish. After they were prefermented at 18℃ for 24 hours, stored 35 days at 4℃. Generally optimal maturity of Kimchi showed pH 4.4 to 4.6, lactic acid content 0.3 to 0.4% at salt content belows 2.5%. The content of total vitamin C in Kimchies was approximately 19.8-24.7 mg/100g at the initial stage of fermentation and then slightly decreased. When the process of the fermentation was active, the content of total vitamin C increased up to the same level or higher than that of the initial stage and then gradually decreased. In the case of Kimchi which added garlic, the content of vitamin C was relatively higher then the other samples. In the initial stage of fermentation, the nitrate and nitrite content in the Kimchi which added garlic and raddish were relatively higher than other samples. Nitrate content reached its minimum by the 21st day, at that time content was 290-342 ppm. At this time, the nitrite was not detected and total vitamin C content in all samples decreased.
