This study surveyed the Korean Kimchi preference for Chinese, potential Kimchi improvement for Chinese market adaptation and Kimchi application for Chinese cuisine, with the aim of spreading the recognition of Kimchi throughout the world, especially in China, by giving information and developing local types which could be expected to be suitable for utilization of Chinese food life. The subjects were consisted of 298 Chinese(male 108, female 190) residing in Weihai, Yantai and Qingdao, in Shandong province. The questionnaire form was developed and used for self administered evaluation. The collected data were analyzed by SAS package. Baechu Kimchi was found to be the most well-known Kimchi for Chinese, and Kkakdugi, Oi Kimchi, Yoelmu Kimchi and Nabak Kimchi were followed in order. Baechu Kimchi(75.9%) was found to be the most favorite Kimchi for Chinese, and Oi Kimchi(59.3%), Kkakdugi(52.8%), Nabak Kimchi(39.3%) and Yoelmu Kimchi(37.7%) were followed in order. The subjects knew about the Korean foods made with Kimchi, such as Kimchi kimbap(74.8%), Kimchi bibimbap(71.5%), Kimchi bokkeumbap(61.7%), Kimchi guk(58.1%) in order. But the experience of consumption for Korean foods made with Kimchi was low compared to the knowledge of the Korean foods made with Kimchi. Chinese's most favorite foods made with Kimchi were Kimchi bossam, Kimchi bibimbap, Kimchi bokkeumbap and Kimchi kimbap, Kimchi bokkeum, Kimchi tteoksanjeok and Kimchi jeon in order. Among the 9 kinds of new Chinese foods made with Kimchi, Kimchi chao zhurou(fried pork with Kimchi), Kimchi chao mian(fried noodle with Kimchi), Kimchi chao youcai xiaren(fried rape and prawn with Kimchi), Kimchi zhuroushuijiao(dumpling with pork and Kimchi), Kimchi gedatang(wheat flakes soup with Kimchi) and Kimchi hundun(dumpling with Kimchi), and Kimchi youbing(panfried flour with Kimchi), Kimchi lamian(handmade knife-cut noodle with Kimchi) and Kimchi tangyuan(tangyuan with Kimchi) were preferred foods by the subjects in order.

recA 유전자를 특이적으로 증폭하는 PCR을 이용하여 우리나라 전통 침채류 발효에 관여하는 유산균의 다양성을 검토해 보았다. 김치에서 많이 검출되는 유산균 7종 및 대조군으로 Lactobacillus acidophilus를 검출할 수 있는 특이적 PCR primer pair을 이용하여 전통 침채류 5증(갓김치, 동치미, 배추김치, 오이소박이, 총각김치로부터 추출한 DNA를 template로 PCR을 수행한 결과, 5종의 침채류 모두에서 Lactobacillus plantarum과 Lactobacillus sakei가 검출되었지만, Lactobacillus paraplantarum, Lactobacillus pentosus와 대조군인 Lb. acidophilus는 검출되지 않았다. Lactobacillus brevis와 Leuconostoc citreum은 배추김치에서만 검출되었으며, Leuconostoc mesenteroides의 경우 갓김치, 동치미, 배추김치, 오이소박이에서 검출되었다. 주재료의 종류에 따라서 발효에 관여하는 유산균은 차이가 있는 것으로 추정되며, Lb. plantarum과 Lb. sakei가 우리나라 침채류 발효에 가장 널리 관여하는 것으로 사료된다.

김치발효중 기체조성변화가 숙성정도를 감지할 수 있는지 알아보기 위하여 배추김치를 플라스틱 용기에 일정량 충진하여 밀봉한 후 저장하면서 포장내 기체조성 변화를 조사한 결과, 김치발효중 포장내 기체조성은 $CO_2$ 발생으로 인하여 계속적으로 변화하였다. 김치 발효온도와는 무관하게 $O_2$ 농도는 지수적으로 감소하고 $CO_2$ 농도는 매우 특징적인 2단계 증가양상을 나타내었다. $CO_2$ 농도는 2차 단계에서 다시 증가함에 따라 김치의 pH는 비례적으로 감소하였다. 저장 온도와 계절별 원료 배추에 따라 김치 포장내 $CO_2$ 농도변화 속도가 다르며 최종 농도에 있어서도 상당한 차이를 나타내었다. 고온에서 발효된 김치일수록 포장내 $CO_2$ 농도가 더 높은 경향을 보였고 여름배추 보다 겨울이나 봄 배추로 제조한 김치에서 포장내 $CO_2$ 농도 및 발생속도가 더 높게 나타났다. 이러한 연구결과를 바탕으로 포장내 기체조성 변화를 이용한 김치의 숙성도 감지 가능성을 확인할 수 있었다.

두뇌기능을 활성화시킬 수 있는 새로운 기능성 김치를 개발하기 위하여 다양한 농도의 흑삼추출물을 첨가한 배추김치를 제조한 후 $4^{\circ}C$에 30일간 저장하면서 경시적으로 김치의 물리화학적 생물학적 관능적 품질을 측정하였다. 0.5~5% 흑삼추출물을 첨가한 김치의 색도를 측정한 결과, 대조구보다 L 값은 감소하고 a 값과 b 값은 증가하여 김치의 색은 암갈색~흑색을 나타내었다. 1~5%의 흑삼추출물을 첨가한 김치는 대조구보다 pH 감소 및 산도 증가가 늦게 나타났고, 경도의 감소 경향도 낮았으며 젖산균 및 효모 증가도 더디게 나타났다. Acetylcholinesterase 활성 저해정도를 측정하였을 때, 흑삼처리구는 대조구보다 약 2배 정도 높은 저해도를 나타내었으며 흑삼의 첨가 농도가 높을수록 저해 정도가 높았다. 김치의 최적 숙성 적기를 전후하여 관능검사를 실시한 결과, 1~3% 흑삼처리구는 흑삼농도가 높을수록 관능특성이 높았으나, 5% 흑삼처리구는 김치에서 흑삼의 맛과 향이 강하여 관능특성이 대조구보다 낮았다. 김치를 제조할 때에 흑삼추출물을 첨가하면 처리농도에 비례하여 김치의 가식기간이 약 15일 정도 연장되었다. 따라서 두뇌기능활성화 효과가 있는 김치를 제조할 때에는 3%의 흑삼추출물을 첨가하는 것이 가장 효율적인 것으로 사료되었다.

This study investigates the kimchi from Jangsu area (JSK) and its comparison with commercial kimchi (CMK). We conducted a sensory evaluation for the pH, titratable acidity, salinity, hunter's color values and mechanical characteristics of kimchi. The pH of JSK is significantly higher than CMK throughout the fermentation (p<0.001). At 15 days, JSK reached the stage of optimal maturity for pH 4.23~4.55 and CMK showed pH 3.96~4.00 as conditions after the optimal maturity (p<0.001). From the results of acidity analyses, CMK also showed higher acidity values than JSK (p<0.001), indicating that the rate of fermentation progress was faster in CMK. Salinity of JSK was a litter higher than CMK1 and CMK2 (p<0.001) and JSK indicated significantly higher L, a, b values during fermentation (p<0.001). Moreover, the textural values were significantly higher in JSK2 and JSK3 retaining hardness of the tissues. In the sensory assessment, the color, flavor, crispness, taste, and overall preferences were higher in JSK3 at 15 days and 30 days than CMK. Therefore, it seems necessary for recipe developments of kimchi with local characteristics in order to industrialize kimchi by using alpine crops at Jangsu area.

This study was conducted to provide basic data on the amount of sodium and the setting of permissible error range of actual measurement, which is a problem for cabbage kimchi nutrients subject to labeling. The sample targeted was baechu (Kimchi cabbage) kimchi, which might have a large variation in sodium content by part of kimchi. Kimchi samples were collected twice from eight companies by season (spring, summer, fall, and winter). The average sodium content in kimchi samples was 619±87 mg/100 g (range, 534±63 mg/100 g to 783±40 mg/100 g). The error in average annual sodium content of abandonment kimchi (maximum value difference compared to the minimum value) was 26.8 to 64.3%. Sodium contents in kimchi produced in spring and summer were relatively low. However, deviation between individuals was large. It was found that cases exceeding the permissible error (120%) standard varied depending on the criteria for setting the amount of sodium. In addition, due to seasonal differences, sodium content in kimchi exceeded 120% of the labeling value. Thus, it is necessary to set standards suitable for characteristics of kimchi to prevent unintentional violations of labeling standards by raw materials and manufacturing processes.

In this study, the FFQ-50 questionnaire which composed of 50 food items frequently eaten as sources of dietary fiber, was developed and used to estimate the dietary fiber intake of middle school students in the Chungbuk province. According to the survey, the average daily intakes of dietary fiber for the boys and girls were $23.3{\pm}12.3$ g (93.2%) and $20.8{\pm}11.5$ g (104.0%), respectively, showing a significant difference between the gender. The proportions of boys and girls who did not reach to the sufficient dietary fiber intake were 66.2% and 53.9% respectively. The major sources of dietary fiber were grain foods and vegetables, which measured at 77.24%, followed by fruits, seaweeds, tofu and tofu products, potato and starch, and mushrooms. The cooked white rice contributed the highest (17.81%), followed by baechu-kimchi, cooked brown rice, ramyeon (instant noodle), tangerine, sesame leaf jangajji (pickled sesame leaf), topokki (spicy rice cake stir-fry), blanched and seasoned bean sprouts, bread, and radish kimchi. The study showed that the cooked white rice was the major source of dietary fiber in the boys' diet followed by baechu-kimchi, ramyeon, cooked brown rice, tangerine, bread, strawberry, blanched and seasoned bean sprouts, sesame leaf jangajji, radish kimchi. Girls were taking in dietary fiber mostly from boiled white rice followed by baechu-kimchi, boiled brown rice, tangerine, ramyeon, sesame leaf jangajji, topokki, blanched and seasoned bean sprouts, radish kimchi, and boiled barley.
