본 연구는 마를 활용하여 마죽을 만든 다음 양념으로 마김치를 제조하였다. 마의 농도는 3%(W/W)로 하여 마맛김치, 마깍두기, 마포기김치를 제조한 다음 영양성분 및 관능 평가를 실시하였으며, 그 결과는 다음과 같다. 시료 100 g 당 3 종류의 마김치 열량은 35~40 kcal이였으며, 조지방, 포화지방, 트랜스지방 및 콜레스테롤은 검출되지 않았다. 나트륨 함량은 450~650 mg으로 마맛김치군 < 마깍뚜기군 < 마포기배추김치군 순으로 높은 함량을 보였다. 3종류 마김치의 비타민 C 함량은 저장 기간 28일에 급격히 높은 증가량을 보였으며, 마깍뚜기에 비해 마맛김치와 마포기배추김치에서의 비타민 C 함량이 크게 증가되었다. 3종류의 마김치 모두에서 Ca, K, Mg의 함량은 높았다. 마김치의 염도는 담금 직후부터 28일까지 맛김치와 깍두기에 비해 포기배추김치 염도가 2.38~ 2.72%의 적정염도를 유지하였다. 맛김치와 배추포기김치는 저장기간이 늘어나면서 명도값은 증가된 반면에 적색도값은 감소되는 경향을 보였으며, 대조군에 비해 마를 첨가한 실험군에서 높은 황색도값을 보였다. 3종류 마김치의 경도는 저장기간이 길어질수록 낮아졌다. 3종류 마김치의 관능검사에서는 대조군과 마를 첨가한 실험군 간에 큰 차이는 없었다.

같은 재료를 사용하면서도 김치를 담글 때에 배추의 형태가 다른 포기김치와 맛김치의 발효중에 일어나는 품질특성의 차이점을 알아본 결과는 다음과 같았다. 맛김치는 포기김치에 비하여 $20^{\circ}C$에서는 2일 정도, $5^{\circ}C$에서는 10일 정도 발효가 빨리 일어났다. 김치를 $20^{\circ}C$에서 발효시킬 때에는 포장내의 이산화탄소 농도가 3일까지는 증가하였으나 그 이후에는 감소하였고, 산소의 농도는 3일 이후에 증가하기 시작하였다. 김치 즙액의 색도는 발효 온도에 관계없이 L, a 및 b값 모두 발효가 진행됨에 따라 증가하였다. $20^{\circ}C$에서 발효시킨 맛김치의 젖산균수는 포기김치에 비하여 전반적으로 높았다. $5^{\circ}C$에서 발효시킨 맛김치는 20일까지 포기김치에 비하여 젖산균수가 많았으나 그 이후에는 포기김치의 값이 높았다. 관능검사에서는 냄새, 색 및 맛에서 두 김치간에 큰 차이가 없었다.

In this study, we produced kimchi with cooked Dioscorea batatas yam based on the its outstanding nutritional value, biological activity, and pharmacological action. Sliced kimchi cabbage, processed white radish kimchi (kkakdugi), and whole kimchi cabbage were prepared with 3% Dioscorea batatas, and the physicochemical and bioactivity characteristics were analyzed. In three kinds of Dioscorea batatas. The pH of the kimchi decreased and its acidity increased as the storage period was extended. The period of the maximum total viable cell count of the sliced cabbage and the processed white radish kimchi (kkakdugi) was 14 days, while the period for whole kimchi cabbage was 21 days. The period of maximum lactic acid bacteria count was 14 days for all three kinds. For physiological activities, polyphenol and flavonoid contents and DPPH elimination were highest immediately after production of the kimchi. Also, anthocyanin content increased as the storage period extended. The pH, acidity, total viable cell count, lactic acid bacteria count, and physiological activities were shown to be different according to the type of kimchi and the storage period.

He purpose of this study was to provide basic data for improvement commercial kimchi quality. To examine the consciousness of commercial kimchi, college students residing in the Jeonnam area were selected and asked to questionnaires. Commercial kimchi samples used included a total of 7 kinds which were fermented for 2 week at $4^{\circ}C$. A sensory characteristics included 10 items with a 5-score scale: color, savory taste, carbonated taste, sour taste, hot taste, salty taste, bitter taste, off-flavor, texture, and overall preference. 76% of the whole student liked kimchi, especially well-fermented kimchi(43.2%) and kimchi with fermented fish(48.6%). Participants liked savory(21.6%), hot(17.1%), and crispy(14.4%) taste. Their most favorite kimchi was the whole cabbage kimchi(26.1%), wild lettuce kimchi(0.9%) and watery kimchi made of sliced radishes(1.8%) were low in preference. 56.8% of participants had no experience in making kimchi. They mainly bought commercial kimchi in grocery stores(37.8%) or shopping malls(29.7%). They pointed out the addition of artificial sweeter(35.1%), insanitation, and discredit of kimchi materials(21.6%) as problems of commercial kimchi. The sensory characteristics of commercial fresh kimchi was significantly different in color($2.6{\sim}4.1$), and hot($2.3{\sim}3.8$), and salty($2.6{\sim}3.5$) with p<0.001. The sensory characteristics of $4^{\circ}C$-fermented commercial kimchi for 2 week was significantly different in color($2.7{\sim}3.9$), and salty($2.1{\sim}4.0$) with p<0.001. It was found that color, and hot, and salty taste had the greatest effect on the overall preference in non-fermented kimchi, and color and salty taste, in 2 week fermented kimchi

This study aimed to evaluate the characteristic differential between whole cabbage kimchi (pogi kimchi) and sliced cabbage kimchi (mat kimchi) during kimchi fermentation at $6^{\circ}C$. The difference of microbial and physicochemical properties was investigated until 6 weeks. For the changes in the microbial flora, both kimchi samples exhibited a continuous increase in total aerobic bacteria and lactic acid bacteria (LAB) population size up to 2 weeks followed by a stationary phase until 5 weeks. Interestingly, the number of LAB of mat kimchi was overall higher than that of pogi kimchi during kimchi fermentation. We speculate that mat kimchi has in a more advantageous growth condition than pogi kimchi for microbial growth because small kimchi cabbage size appropriately derives nutritional supply in order to increase the LAB growth. During lactic fermentation at $6^{\circ}C$, physicochemical changes in the pH, salinity, and titratable acidity was observed to be no significant differences between two types of kimchi. Furthermore the contents of organic acids such as oxalic acid, citric acid, malic acid, lactic acid, fumaric acid, and acetic acid was not significantly different (p>0.05) between both kimchi samples as well as the contents of total free amino acid.
