  • Physico-chemical and sensory characteristics of six dongchimi cultivars were evaluated. Moisture and sugar contents were 94.2% and $4.30^{\circ}Brix$ for three spring radish cultivars, while 92.9% and $7.30^{\circ}Brix$ for three autumn ones. pH $(5.7{\sim}6.1)$ and acidity $(0.09{\sim}0.12%)$ did not show significant differences among cultivars. pH decreased steadily up to 21 days to reach optimum pH of 4.0. The maximum number of total lactic acid bacteria, $10^8{\sim}10^9\;CFU/mL$, was reached at pH 4.0. The final acidity of spring radishes was lower than that of autumn ones, and was proportional to the sugar content of the radishes. The firmness of spring radish decreased rapidly compared to the autumn ones. Cheongbok was found suitable for dongchimi, because its firmness level was maintained around $165.0{\times}10^3\;N/m^2$ at 35 days. Sensory evaluation revealed 96371 among spring radishes and cheongbok among autumn radishes scored high in firmness, chewiness, flavor, and overall acceptance. These results suggest that autumn radishes are suitable for dongchimi fermentation with cheongbok being the best among the cultivars.

  • The study was conducted to investigate the changes of soil properties and evaluation of plant utilization according to the application of compost used with phyllite. At this experiment, the plant cultivation test(lettuce and radish plant) was carried out to know about physico-chemical properties of compost, humus degradarion and stabilization degree, and some effects among rhe treatments were best at 20Mg/ha in PSPC 10(Phyllite, Saw dust, Pig manure Compost) plots and ar 10Mg/ha in PSPC 20 treatments, respectively. The EC value was high in the compost. Therefore the EC was appeared more than 2ds/m at the applied 40Mg/ha with compost. And in case of lettuce, Avail.-$P_2O_5$ and EC were more increased than in the radish plots, highly. In contrast, in case of radish, Toral-N, Total-C, and EC contents were decreased after plant cultivation. That is, it could know that radish was fond of absorprion of nitrogen. Also, BD values of soil physical properties were decreased according to increasing of phyllite addition ratio, however water holding capacity(WHC) was increased. The plant test had not been darnaged through the application of compost used with phyllite in soil and there had not been worse on changing of soil physico-chemical properties. Consequently, phyllite composts have been thought on agricultural utilized possibility.

  • Common cruciferous vegetables, kohlabi (Brassica oleracea) and radish (Raphanus sativus), contain phytochemicals such as glucosinolates and carotenoids. Therefore, this study investigated the antioxidant and anti-adipogenic effects of kohlrabi sprout extract (KSE) and radish sprout extract (RSE). The total carotenoid and glucosinolate contents of KSE and RSE were $39.50{\pm}0.67$ and $76.73{\pm}2.75mg/g$, respectively. The total glucosinolate contents of KSE and RSE were $2.65{\pm}0.02$ and $8.13{\pm}0.54mg/g$, respectively. The in vitro-antioxidative activities of KSE and RSE were significantly increased in a dose-dependent manner. Furthermore, ${\beta}$-carotene and glucosinolate-enriched KSE and RSE significantly inhibited lipid accumulation and reactive oxygen species production during the adipogenesis of 3T3-L1 preadipocytes. These results suggest that glucosinolate-enriched KSE and RSE, especially RSE, can be used in the treatment of obesity and as a natural source of antioxidants.

  • Young radishes (YR, yeolmu in Korean) were cultivated in the soil with and without sulfur. YR-Control (without sulfur) was grown in the normal soil. YR were grown in the soil with $1,818\;g/m^3$ sulfur (YR-A) and $1,818\;g/m^3$ sulfur added lime mortar (YR-B) on it, respectively. Also, we prepared YR kimchis using YR-Control, YR-A and YR-B. The kimchis were fermented at $5^{\circ}C$ for 8 weeks. The growth inhibitory effects of AGS human gastric adenocarcinoma cells of the YR samples and kimchis were investigated. YR kimchis after $4\~5$ weeks at $5^{\circ}C$ showed higher acidity of $0.88\~1.20\%$ with pH $4.3\~4.5$ and the YR kimchis kept approximately pH 4.0 until 8 weeks. The kimchi A and B using YR-A and YR-B showed faster fermentation time, higher level of Leuconostoc sp. and lower level of Lactobacillus sp. during the fermentation, comparing to the control kimchi using YR-Control. Juices from YR-A and YR-B showed higher growth inhibitory effects of AGS human gastric adenocarcinoma cells than the juice from YR-Control at the same concentration. The growth inhibitory effect of YR-A was similar to that of the YR-B. The kimchi A and B juices also exhibited higher inhibitory effects $(74\%)$ on the growth of AGS human gastric adenocarcinoma cells than that of the control kimchi $(57\%)$ at the higher concentration of $20{\mu}L/assay$. Methanol extracts from the YR-kimchis also led to the similar results to the results of the juices. These results suggested that preparing of kimchi using differently cultivated YR especially in the soil with sulfur, which can help to synthesize sulfur-containing compounds, could increase the growth inhibitory effects of AGS human gastric adenocarcinoma cells.

  • Effects of cucumber and tomato seed germination by previous leaf and root vegetables (cabbage, radish, welsh onion, lettuce) residue in soil were tested in pot condition. Overall, suppression effect of welsh onion residue was the greatest in 4 tested crop residue and followed by radish, cabbage and lettuce, but lettuce residue didn't have effect on cucumber seed germination. Suppression were maintained ca. 20 days but after the time point, growth of cucumber and tomato were enhanced. Enhancing effect of welsh onion residue was the greatest in 4 tested crops residues and followed by radish, cabbage and lettuce. As a conclusion, residue of welsh onion, radish and cabbage were suppressed the germination of cucumber and tomato seeds but enhanced growth after 20 days of treatment. To verify the effective concentration of residue on suppression of germination and growth of radicle of cucumber and tomato, plant extract of welsh onion, radish, cabbage and lettuce were diluted as 5, 10, 17, 23, 35, 50, and $65\%$, and then tested. In low concentration treatment, 5, 10, 17, and $23\%$, all 4 crop extracts didn't suppress cucumber seed germination. High concentration of lettuce extract, 35, 50, and $65\%$, cucumber seed didn't germinate at all. In case of welsh onion extract, only $65\%$ treatment suppressed cucumber seed germination. In low concentration treatment, 17, and $23\%$, only the welsh onion extract suppressed young radicle. In case of high concentration treatment, except $35\%$, all four crops extract suppressed cucumber radicle growth. In low concentration treatment, tomato seed germination was suppressed by lettuce extract only but in high concentration treatment, 35, 50, and $65\%$, all extracts suppressed germination. Especially higher than $50\%$ treatment, tomato seed didn't germinate at all. Radicle growth was highly suppressed in welsh onion and lettuce extract, higher than $23\%$ concentration. As conclusion, leaf and root vegetable extracts suppressed cucumber and tomato seed germination and in high concentration, also suppressed radicle growth.

  • This study was conducted to evaluate the quality characteristics of pickled radish wrap supplemented with calcium chloride ($CaCl_2$) at different concentrations. With $CaCl_2$ supplementation, initial pH and acidity were 3.8~4.0 and 2.7~3.0% (w/v), respectively. During the 28 day-preservation at $4^{\circ}C$ or $50^{\circ}C$, the initial pH and acidity were maintained. However, when the pickled radish wrap was preserved at $25^{\circ}C$, it had lower pH (by 0.5) and higher acidity (by 1.9~2.2%) when compared with the initial values. The difference in color (${\Delta}E$-value) of the pickled radish wrap preserved at $50^{\circ}C$ was significant (${\Delta}E$-value 23~27), though the hardness of the sample prepared at $4^{\circ}C$ or $25^{\circ}C$ showed no distinguishable differences at various concentrations of $CaCl_2$ supplementation (0.1, 0.2, 03, 0.4, and 0.5%). However, once preserved at $50^{\circ}C$, it resulted in the greater hardness with the higher concentrations of $CaCl_2$ supplementation. In terms of softness, the overall trend in changes was similar to the hardness. A sensory evaluation using the samples preserved at $4^{\circ}C$ for 28 days demonstrated that the preparation with 0.4% $CaCl_2$ ranked highest in taste, hardness and overall acceptability. It wass suggested that supplementation with 0.4% $CaCl_2$ would be most appropriate to improve the textural properties of pickled radish wrap while maintaining its organoleptic quality.

  • 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.
