  • Radish kimchi is a typical side-dish in Korean traditional food and is a way of keeping vegetables for a extended period using fermentation. This study examined the classification, usage, eating history, variety, and recipes of Korean radish kimchi through ancient and modern era literature. The Korean radish kimchi were categorized into six groups: kkakttugi, seokbakji (or nabakkimchi), dongchimi, jjanji, jangachi, and jangkwa. According to the record, the eating history of radish kimchi comes from before the age of the Three Kingdom period. Radish was preserved in salt, vinegar, soybean paste or lees of fermented liquor in the early times. This pickled radish was not supposed to be watery. Radish kimchi was divided into watery kimchi (dongchimi) during the period of United Silla and the Koryo Dynasty. Kimchi was mixed with Chinese cabbage to make seokbakji or nabakkimchi. Up to the early Chosun Dynasty, the key ingredient of kimchi was radish. After the middle of the Chosun Dynasty, kimchi was mixed with red pepper powder, salted fish, soybean sauce, and various ingredients. There were many kinds of radish kimchi during the late Chosun Dynasty. In the 11 Korean recipe books published within the past 100 years, there are nine kinds of kkakttugi, three kinds of seokbakji, four kinds of dongchimi, three kinds of jjanji, nine kinds of jangachi, and five kinds of jangkwa. Kkakttugi (cubed, sliced or julienne radish) was pickled with salt, red pepper powder, garlic, green onion, oyster, sugar, salted fish, and more. Seokbakji and nabakkimchi were not as salty, so they could not be preserved as long. Dongchimi (watery radish kimchi without red pepper powder) was made of radish, water, salt, 18 side ingredients, 13 condiments, and seven garnishes. Jjanji was pickled to be very salty and was eaten during summer. Jangachi can be used as a regular side dish and is made of radish or dried radish slices pickled or seasoned with salt, soy sauce, vinegar, soybean paste, lees of fermented liquor, and spices. Jangkwa is used as a stir-fry method and has been segregated from jangachi relatively recently.

  • This study was performed to determine the effects of different processing methods (AD: drying at $50^{\circ}C$ for 15 h; ADR: roasting after drying; SAD: drying after steaming; SADR: roasting after steaming and drying) on the quality characteristics, total phenolic content, anthocyanin content, DPPH radical scavenging activity, and reducing powder of red radish (Bordeaux and watermelon radish) tea. The pH of red radish tea was the highest with SAD. In terms of the total sugar content, Bordeaux radish tea showed the highest level with AD, ADR, and SAD, and watermelon radish tea showed the highest level with SADR. The a value of Bordeaux radish tea was higher with AD and ADR. The b value of Bordeaux radish tea was increased with steaming and roasting treatment. In terms of measuring the colors of watermelon radish tea, the L value was decreased while the b value was increased with roasting treatment. The total phenolic content, DPPH radical scavenging activity, and reducing powder with ADR and SADR were higher than those in samples prepared by different processing methods. AD and SAD resulted in higher anthocyanin contents than ADR and SADR. In terms of sensory evaluation, the appearance and color were rated higher with AD and SAD, whereas the flavor and taste were ranked higher with ADR and SADR than in the other samples. The results suggest that red radish (Bordeaux and watermelon radish) tea prepared by ADR and SADR processing methods can be utilized as health functional tea material with antioxidant activity.

  • The radish skin and radish greens are an edible part of the radish. But they are removed before eating the radish and used as a byproduct or an animal feed material because of their tough and rough texture. This study was conducted to investigate the effect of supercritical heat-treated radish-extract on UV-induced HRM-2 wrinkled mouse animal model on anti-aging wrinkles. Supercritical heat-treated radish-extract was applied on the back of seven-weeks old HRM-2 mice. The effect of HRE on skin thickness, elasticity and wrinkle formation of the mice was observed by using UVB lamp to induce melanogenesis and wrinkle formation. As the result, increased depth of wrinkles was observed in the negative control group in comparison to the normal group. In contrast, decreased depth of wrinkles was observed in the radish-extract-free group compared to the negative control group. In the study of the effect of radish-extract on wrinkle-formation related gene expression and protein what protein expression, MMP-2 and MMP-9 gene expression significantly increased in the negative control group compared to the normal group. The gene expression reduced in dependence to the mass of radish-extract treated. Similar to quantitative results of mRNA expression, the expression of MMP-2 protein increased as a result of UVB-irradiation. The MMP-2 expression was inhibited in dependence to the mass of radish-extract treated. In conclusion, the supercritical heat-treated radish-extract has an effect on improving skin wrinkles not only when it is applied to the skin but also when orally ingested. Thus, it can be effectively used as a composition to health functional products. Therefore we can also conclude that radish a food that does not show any side-effects even upon long-term intake can reduce wrinkle formation as well as improve skin elasticity when taken regularly for a long period.

  • The Sasang constitution food is classified by Sadang theory(四黨論), Aroma-Scent-Fluid-Taste(馨臭液味), Inhale-Exhale-Incomings-Outgoings(呼吸出納), Ascent-Descent-Open-Close(升降開闔), Healthy Energy(保命之主), which is different from the Oriental medicine herb classification of traditional oriental medicine. So, we obtained the result of the characteristic of radish, one of much used food materials by examining ancient documents as follows. First, today 'Rae(來)' is used as to come' but in ancient days, was used as 'wheat'. Radish(萊服) is the word made by meaning which removes and overcomes the poison of wheat Second, Ancient people realized the power of its Inhale Disperse Qi (呼散之氣) when the root of radish raises quickly from the soil, and recognized that radish has such a good dissolving function when seeing Bean-curd becomes soft if radish is added to Bean-curd dish. That’s why they classified that radish is lung medicine, and used it as Taeumin type medicine. So if someone is suffocated by the smoke and has indigestion, chronic asthmatic coughing, now we use radish by applying the Inhale Disperse Qi of radish.

  • This study was conducted to investigate the physical, textural and sensory properties of Seolgiddeok prepared with different amount of radish leaf powder, and stored for 3 days. The moisture content decreased gradually during storage and the decrease was less in the groups with radish leaf powder than in the control. The color L value decreased significantly as the amount of radish leaf powder increased, while the redness (a) and yellowness (b) both increased. Measurements with a texture analyzer, showed that the hardness, chewiness, gumminess and adhesiveness of Seolgiddeok tended to decrease in proportion to the amount of radish leaf powder in the formula. The gelatinization properties of Seolgiddeok were investigated by amylograph. Breakdown and setback in Seolgiddeok were low following the addition of radish leaf powder. In the sensory evaluation, Seolgiddeok with radish leaf powder was superior in flavor, chewiness, and softness than the control. Seolgiddeok with 3% radish leaf powder had the highest overall acceptability score. Therefore, we concluded that the addition of radish leaf powder to Seolgiddeok improves the sensory characteristics and delays retrogradation.

  • According to statistical data the past ten years, cultivation area and yield of radish are steadily decreasing. This phenomenon cause instability of radish's supply due to meteorological chage, even if radish's yield per unit area is increasing by cultivation technological development. These problems raise radish's price. So, we conducted study on meteorological factors for accuracy improvement of radish yield estimation. Panel analysis was used with two-way effect model considering group effect and time effect. As the result, we show that mixed effects model (fixed effect: group, random effects: time) was statistical significance. According to the model, a rise of one degree in the average air temperature on August will decrease radish's yield per unit area by $428kg{\cdot}10a^{-1}$ and that in the average air temperature on October will increase radish's yield per unit area by $438kg{\cdot}10a^{-1}$. The reason is that radish's growth will be easily influenced by meteorological condition of a high temperature on August and by meteorological condition of a low temperature on Octoboer.

  • Purpose: This study was to investigate the quality characteristics of wet noodle added with radish juice containing with pulp. Methods: Wet noodles were prepared with different amounts of radish juice (0%, 20%, 40%, 60%, 80%, 100%, w/w) instead of water. Results: As the amount of radish juice was increased, water absorption, volume increasing rate, and turbidity of soup were decreased. Lightness (L) values of uncooked wet noodles and cooked noodles were decreased with the addition of radish juice, while redness (a) and yellowness (b) values had no tendency of increasing or decreasing, regardless of the amount of radish juice. Moreover, lightness, redness, and yellowness values of uncooked noodles were higher than those of cooked noodles. The texture of cooked noodles showed significant differences in hardness and chewiness. It was increased as the amount of radish juice was increased. Their adhesiveness and springiness were lower than those of the control. Appearance, texture, and overall acceptability of sensory evaluation revealed that the noodle added with 80% of radish juice had the highest scores, although there were no differences among noodles added with different amounts of radish juice. Conclusion: In summary, the most desirable blending ratio of radish juice and water for the kneading of wet noodles was 80:20.

  • This study investigated changes in the chemical properties and antioxidant activity of dried shredded radish (Raphanus sativus L.). Shredded radishes with a thickness of either 3.5 mm or 7.0 mm were dried using hot air at $45^{\circ}C$ or were sun dried. The degree of browning for the 3.5 mm sun dried radish, the 7.0 mm sun dried radish, the 3.5 mm hot air dried radish and the 7.0 mm hot air dried radish was 0.12, 0.14, 0.04 and 0.04, respectively. The DPPH radical scavenging activity (EDA%) of the hot air dried radish had a higher value than the sun dried radish. In contrast, the ABTS values of the sun dried radishes were higher than the hot air dried radishes. The total polyphenol content of the 7.0 mm and 3.5 mm hot air dried radishes reached high values of 15.99 and 11.62 mg/g, respectively. The total polyphenol contents of the 7.0 mm and 3.5 mm sun dried radishes were 9.63 and 6.77 mg/g, respectively. In sensory evaluation of the stir-fry dried shredded radishes, the 7.0 mm hot air dried sample scored the highest in terms of smell, color, gloss and overall preference. In conclusion, hot air drying ($45^{\circ}C$) and a thickness of 7.0 mm were found to be the optimal conditions for dried shredded radish and stir-fried dried shredded radish products.

  • Previous research has indicated that radish powder could be a suitable replacement for chemical nitrite sources in alternatively cured meat products. However, the effects of radish powder level on the physicochemical properties of cured meat have not been systematically studied. In this study, we aimed to investigate the effects of varying concentrations of radish powder and incubation time on the physicochemical properties and cured meat pigments of alternatively cured meat products. We divided our experimental setup into seven groups with different radish powder concentrations and incubation times: control (0.01% sodium nitrite), treatment 1 (0.15% radish powder and 2 h incubation), treatment 2 (0.15% radish powder and 4 h incubation), treatment 3 (0.30% radish powder and 2 h incubation), treatment 4 (0.30% radish powder and 4 h incubation), treatment 5 (0.30% celery powder and 2 h incubation), and treatment 6 (0.30% celery powder and 4 h incubation). The cooking yield, CIE a* values (redness), and total pigment levels were not significantly different (p > 0.05) between any of the alternatively cured treatments and the control. However, when 0.30% radish powder or celery powder was added to the products, the CIE b* values increased significantly (p < 0.05) with incubation time. At the same vegetable concentration, the nitrite content, nitrosyl hemochrome, and curing efficiency also increased significantly (p < 0.05) as the incubation time increased from 2 to 4 h, regardless of the types of vegetable powder. Among the meat products cured with radish powder, treatment 4 showed the highest increase in residual nitrite content, nitrosyl hemochrome content, and curing efficiency, but showed decreased lipid oxidation. Our results suggest that increased concentrations of radish powder and longer incubation times would be more suitable for producing alternatively cured meat products comparable to traditionally cured products treated with synthetic nitrite.
