In recent years consumers have become used to products geared toward a more convenient lifestyle, thus, the demand for salted-cabbage, for use in preparing Kimchi is increasing. This study aims to investigate purchasing factors, the satisfaction and demands of salted-cabbage, and to ascertain a marketing strategy for expanding the use of salted cabbage in food-service departments of schools. Self-administered questionnaires were collected from 131 buying agents who manage food materials for schools, and statistical data analysis was completed using the SPSS V.14.0 program. 46.9% of the participating respondents were from elementary schools, 27.7% from middle schools, and 25.4% were from high schools.. Most of the subjects (67.9%) recognized the salted cabbage retailed for foodservice, but 62.3% of these had not purchased them, due to both their lack of trust in the sanitation and raw material handling of the food product, and the high price. Respondents considered different factors when deciding whether or not to purchase: the origin (local or imported) of the cabbage, hygiene, and taste, as well as characteristics such as the cabbage weight, package weight, and package materials. The score of post-behavior intentions as well as overall satisfaction was rather high. Also, they perceived the need of strategic promotion for enlarging the market portion of salted-cabbage. These results will done the guidelines for diversifying the salted-cabbage market and for creating an added value of agricultural products in rural areas.

In this study, the effects of a pre-filter system and electrolysis system on the safe and efficient reuse of brine in the cabbage salting process were investigated. First, sediment filter-electrolyzed brine (SF-EB) was selected as brine for reuse. Then, we evaluated the quality and microbiological properties of SF-EB and Chinese cabbage salted with SF-EB. The salinity (9.4%) and pH (4.63) of SF-EB were similar to those of control brine (CB). SF-EB turbidity was decreased (from 0.112 to 0.062) and SF-EB residual chlorine (15.86 ppm) was higher than CB residual chlorine (0.31 ppm), and bacteria were not detected. Salinity (2.0%), pH (6.21), residual chlorine (0.39 ppm), chromaticity, hardness, and chewiness of cabbage salted with SF-EB were similar to those of cabbage salted with CB. The total bacterial count in cabbage salted with CB was increased as the number of reuses increased (from 6.55 to 8.30 log CFU/g), whereas bacteria in cabbage salted with SF-EB was decreased (from 6.55 to 5.21 log CFU/g). These results show that SF-EB improved the reusability of brine by removing contaminated materials and by sterilization.

절임 배추와 숙성된 김치의 동결저장 가능성을 조사하였다. 생배추의 조직은 급속침지동결이나 예비건조하면 완만공기동결이나 건조하지 않은 것에 비해 우수하였다. 절임 배추는 생배추에 비해 동결손상이 적었고 급속동결이나 예비건조에 의해 조직이 개선되지 않아 조직특성은 숙성된 김치와 비슷하였다. 김치는 동결시 동결하지 않은 것에 비해 약간 질겼으나 전체적인 품질에서는 유의적인 차이를 보이지 않았다. 동결저장시 절임배추는 3개월후 약간의 핑크색을 띄었으나 김치는 6개월 저장동안 이런 현상이 나타나지 않았고 품질도 거의 변화가 없었다.

김치가 갖는 신선한 맛과 향을 지니면서 저장성을 유지시키기 위한 기초실험으로서 냉온살균기술의 하나인 오존살균기술을 이용하여 김치 원부재료 중에 가장 함유량이 많은 배추 또는 절임배추에 오존을 처리하였을 때 이들의 미생물학적 및 화학적 특성변화를 저장기간별로 측정하였다. 배추 및 절임배추에 부착된 총균수는 각각 $1.3{\times}10^7$ CFU/g 및 $7.1{\times}10^6$ CFU/g이었으나 오존처리를 한 경우에는 대조군보다 낮은 균수를 보였으며 저장기간이 증가하는 동안에도 대조군보다 낮은 균수를 유지하였다. 효모 및 곰팡이 수는 대조군의 경우 각각 $6.0{\times}10^3$ CFU/g, $1.2{\times}10^3$ CFU/g으로 나타났으나 오존처리시 감균되었으며 저장기간 내내 낮은 균수를 유지하였다. 또한 배추 및 절임배추에 존재하는 성분(ascorbic acid 및 환원당)의 함량 변화와 색도 및 경도의 변화에서는 오존처리에 의한 변화는 대조군과 비교하여 크게 차이가 없는 것으로 나타났다.

Salted Chinese cabbage were dipped in solutions of CaCl2 (0.1%, 0.5%, 1.0%), Ca-lactate (0.5%) alone, or with chlorine (NaOCl 200ppm) and stored at 3 or 23$^{\circ}C$ to determine the effects of calcium (Ca) on storage quality. pH change and microbial growth of salted cabbage were reduced in CaCl2 of 0.1% and 1.0% more than in the water-dipped control but better than in NaOCl treatment at two temperatures. Storage quality of salted cabvage was not affected by Ca contents or Ca with Cl treatment.

절임 배추의 저장 기간을 연장하기 위하여 배추를 절인 다음 전해산화수로 세척하고 저장하면서 품질 특성의 변화를 측정한 결과는 다음과 같았다. 즉 절임 배추를 전해산화수로 세척한 처리구가 대조구보다 낮은 pH를 보였으며, 저장 8일까지는 대조구에 비하여 낮은 pH를 나타내었다. 적정산도는 저장기간 동안 0.11-0.15%로 큰 변화를 나타내지 않았으며, 대도구와 처리구간에도 큰 차이가 없었다. 절임 배추를 전해산화수로 세척한 직후에는 대조구에 비하여 총균수가 $10^3\;CFU/mL$ 정도 낮았으나 처리구의 총균수는 저장 6일에 대조구와 비슷하였다. 유산균수도 세척 직후에는 처리구가 대조구보다 낮았으며, 저장 4일에는 대조구와 처리구의 차이가 가장 현저하였다. 저장 2일까지는 국물의 밝은 정도(L)에 있어서 대조구와 처리구간에 차이가 없었으나 그 이후에는 처리구가 대조구보다 높은 값을 나타내었다.

절임배추와 양념으로 구성된 제품에 대한 품질 특성 정보를 제고하고, 버무린 형태로 저장된 김치와 절임배추와 양념을 분리 저장한 후 버무린 김치의 품질 특성의 차이를 확인하기 위해 $4^{\circ}C$에서 저장하면서 1주 간격으로 품질특성을 분석하였다. 절임배추의 산도 및 일반세균수 변화 결과, 염수 침지에 따른 절임배추의 품질유지 효과가 나타났으며, 외관 및 관능적 품질 특성 결과를 토대로 염수 침지하지 않은 절임배추의 저장한계는 1주, 염수침지한 절임배추의 저장한계는 2주 이내임을 알 수 있었다. 특히, 염수량이 많을수록 품질 유지에 더욱 효과적이었으며 관능적 특성에서도 다소 높은 점수를 받았다. 양념은 저장 8주 동안 산도가 증가하는 경향을 보였으나 미생물학적 및 관능적 품질특성에는 큰 변화가 없었다. 0일차에 제조하여 $4^{\circ}C$에서 저장한 김치와 $4^{\circ}C$에서 각각 저장된 절임배추와 양념을 이용하여 매주 제조한 김치의 품질 특성을 분석한 결과, 0일차에 제조하여 저장한 김치보다 저장된 절임배추와 양념으로 매주 제조한 김치의 pH가 높고, 산도가 낮아 발효 지연효과가 있는 것으로 나타났다. 특히 3주차 저장된 절임배추와 양념으로 제조한 김치의 경우 신냄새, 신맛 등의 지표에서 김치형태로 저장된 것보다 유의적으로 낮은 점수를 받았다. 전반적인 기호도에서도 분리 저장 후 제조한 김치에서 높은 점수를 받았으나 유의적인 차이는 확인되지 않았다. 이상의 결과, 절임배추와 양념으로 제품화할 경우 절임배추는 품질유지를 위해 염수에 침지하여 포장하는 방법이 효과적이며, 분리 저장된 절임배추와 김치 양념을 혼합하여 김치로 제조하여도 처음부터 김치 형태로 제조하여 저장한 것과 비교하여 발효가 지연되면서 관능적으로도 문제가 없어 김치의 가식기간을 연장할 수 있는 방법이 될 것으로 생각된다.

Chemical, physical md microbial analysis of salted baechu(Chinese cabbage) and its exudate were conducted during storage in large plastic bags(LDPE, HDPE, PVC-box) at 0$^{\circ}C$. Salinity was slightly lowered for 2 weeks storage and maintained that level thereafter in salted haechu, but in its exudate increased rapidly for 2 weeks storage and decreased thereafter. In all treatment pH decreased to 5.0 in salted baechu and to 4.5 in its exudate for 6 weeks storage. Reducing sugar content of salted baechu was 1.5∼2.0 fold higher than that of its exudate, and decresed slowly in both. Total viable cells increased rapidly for 2 weeks but maintained that level thereafter and lactic acid bacteria increased continuously until 6 weeks. Lightness of exudate decreased rapidly in PVC-box, but decreased slowly in LDPE. Compression force of salted baechu increased continuously untill 8 weeks except for PVC-box.

The principal objective of this study was to evaluate the influence of temperature and salt concentration on the physicochemical properties of salted Chinese cabbage. Salted Chinese cabbage samples were prepared with various concentrations of salt(4, 5, 6 and 7%), and were stored for 10 days at three temperatures(8, 14, and $25^{\circ}C$). The salting ratio of Chinese cabbage evidenced a decreasing trend regardless of the salting temperature and salt concentration, and their decrement appeared relatively high as the salting temperature increased. The period required to achieve a critical salting ratio(85%) decreased with increases in the salt concentration at $25^{\circ}C$, and a similar trend was observed at lower temperatures(8 and $14^{\circ}C$). The salinity of all samples evidenced an increasing trend during the salting period, and at $25^{\circ}C$, in particular, a continuous increment was observed. At salt concentrations of 4%, the critical salinity(2.2%) was not achieved regardless of the temperature and salting period. The pH of salted Chinese cabbage achieved critical pH in 3 days at a salting temperature of $25^{\circ}C$, but the critical pH 5.5 of samples at 8 and $14^{\circ}C$ appeared after a long period of approximately 4 to 10 days. The average hardness values of salted Chinese cabbage at a salting ratio of 85% were approximately 1.49 MPa, 1.87 MPa, and 1.97 MPa, respectively, at three temperatures($25^{\circ}C$, $14^{\circ}C$, and $8^{\circ}C$). The initial reducing sugar content of cabbage juice was 11.8 mg/$m{\ell}$, and this value decreased substantially to 3 to 5 mg/$m{\ell}$ on day 1.

This study was conducted to determine the optimum conditions for the preparation of traditional Korean whole cabbage Kimchi with salted shrimp. Sensory, physical and chemical characteristics of Kimchi with various salted shrimp level(1.8, 3.6%), fermentation time(12, 24, 36 hrs) and storage period(1, 4, 7 days) were measured. As the fermentation time and storage day were extended, pH of Kimchis decreased but titratable acidity of Kimchis increased. The more salted shrimp in Kimchi resulted in the higher titratable acidity. The longer fermentation time and the longer storage resulted in the more citric, malic and succinic acid, and the less lactic and acetic acid in Kimchi. The optimum conditions for the preparation of Korean whole cabbage Kimchi were 3.6% salted shrimp level, 12 hours fermentation time and 84 hours(3.5 days) storage period.
