Since there has not been a pickle made out of radish and carrots among the foods. We come up with the idea of making a pickle with radish and carrot. To examine the value that two kinds of pickle can carry out as a food, we utilize several methods : such as the examination of changes of color, hardness. PH, total bacteria and sensory test to investigate characteristics of a radish and carrot pickle during the storage.

This study was conducted to examine the quality characteristics of radish pickle added with different amounts of white wine (0, 3.75, 7.24, 10.48, and 13.50%), stored for 0, 1, 2, 3, and 4 weeks. The sugar content of the pickle solution decreased significantly(p<0.001) as the concentration of white wine increased, and decreased significantly(p<0.001) as the period of storage lengthened. The pH value of the pickle solution increased significantly(p<0.001) as the concentration levels of white wine rose. And a period storage decreased significantly(p<0.001) during the period of storage from week 0 to week 4 [makes no sense; recommend deletion]. The L-value of the solution increased significantly(p<0.001) with increasing concentrations of white wine, while the a-value and b-value both decreased. In addition, the L-value of radish pickle decreased significantly(p<0.001) as white wine concentrations increased, while the a-value and b-value increased. The hardness of the radish pickle increased significantly(p<0.001) when white wine concentrations were increased after 1 week. Hardness decreased significantly(p<0.001) during the period of storage. According to the results of sensory tests, appearance, taste, and overall preference were higher in the 30% additional sample[I can't find what this refers to]. These results are expected to be useful in producing radish pickle of optimal quality and to contribute to the development of various foods and the advancement of the food industry.

Physicochemical and antioxidant activity characteristics of radish pickles added with different amounts of stevia leaf (0, 1.0, 2.0, and 3.0 g) were investigated. Radish slices ($4{\times}4{\times}4cm$) were salted with NaCl, soaked into pickling solution added with different amounts of stevia leaf, and then stored at $4^{\circ}C$ for 6 months. Throughout the whole storage periods, L and b values of radish pickles increased significantly with increasing amount of stevia leaf, whereas a value decreased. Hardness and strength increased significantly with increasing amount of stevia leaf during the storage period. Antioxidant compound contents and antioxidant activity increased significantly with increasing amount of stevia leaf. These results are expected to be useful in producing stevia leaf radish pickles with antioxidant activity and we propose the manufacture and commercialization of radish pickles added with 2.0 g of stevia leaf.

순무(Brassica rapa L., Brassica campestris L.)는 십자화과에 속하는 채소로 무의 일종이다. 모양은 팽이와 유사하고 껍질은 적자색을 띄고 있다. 이를 원료로 한 연구로 피클, 젖산발효, 식이섬유소의 함량, 성분분석에 관한 연구 등이 보고되어 있다. 본 연구에서는 순무를 활용한 농가형 음료 및 식품 소재 개발의 일환으로 자당 첨가량과 발효온도를 달리하여 순무 발효액을 제조하고 이화학적 특성을 검토하였다. 순무는 강화군 농가에서 직접 구입하였다. 순무를 $4{\times}5{\times}1cm$의 크기로 세절하고 중량대비 40%, 60%, 80%, 100%의 자당을 첨가한 다음 $24^{\circ}C$에서 15일간 발효하였다. 또한 발효온도에 따른 변화는 60%의 자당을 첨가하여 $18^{\circ}C,\;24^{\circ}C,\;30^{\circ}C$에서 21일간 발효하였다. 시료는 3일 간격으로 채취하여 수율, 당도($^{\circ}Brix$), 산도(acetic acid, %), pH를 조사하였다. 자당 첨가량이 추출 수율에 미치는 영향은 40%, 60%, 80%, 100% 순으로 각각 39.14%, 55.38%, 53.56%, 55.72%로 40%를 첨가한 군을 제외하고 차이가 없었다. 당도와 pH는 자당 첨가량이 높을수록 증가하였고 총 산도는 각각 0.415, 0.446, 0.242, 0.194 (acetic acid, %)로 나왔다. 발효온도에 따른 당도와 pH의 변화는 시간이 경과할수록 감소하였으나 산도는 발효 15일 이후에는 $30^{\circ}C$가 $24^{\circ}C$보다 점차 높아졌다. 총산도의 변화는 $24^{\circ}C$와 $30^{\circ}C$에서 차이가 없었다. 본 실험의 결과에서 볼 때 순무발효액을 추출하기 위한 가공조건은 60~80%의 자당을 첨가하여 $24^{\circ}C$에서 15일간 발효하는 것이 적당한 것으로 사료된다.

This study examined the physicochemical properties of radish pickle containing different natural preservatives (grapefruit seed extract, green tea extract, rosemary, or olive) stored for 0, 1, 2, 3, and 4 weeks. The hardness and color of the radish pickles with the grapefruit seed extract was higher than the other radish pickles during storage from week 0 to week 4. A 14.52% and 13.80% decrease in hardness and color were observed in the radish pickles with grapefruit seed extract (GFE), respectively. In addition, the total phenolic content was highest in the GFE in natural preservatives. Based on the results, GFE was selected as the optimal natural preservatives, and the growth of total viable bacteria and yeast were evaluated. The total viable bacteria and yeast showed similar patterns to the control. These results are expected to be useful in producing radish pickles with optimal quality and contribute to the development of various foods in the food industry.
