무 에탄올 추출물의 미백기능, 숙취해소, 항균활성 및 항산화능을 분석하였다. Tyrosinase inhibition assay법을 이용하여 미백활법을 측정한 결과 무 줄기와 무 뿌리 추출물의 $IC_{50}$(50% inhibitory concentration)은 각각 0.9 mg/ml와 2.1 mg/ml를 나타냈다. 무뿌리 추출물보다 무줄기 추출물이 2.5배 정도 높은 tyrosinase의 저해율을 보였지만, 무의 품종별로는 별다른 활성 차이를 보이지 않았다. 숙취해소 활성의 분석법으로는 alcohol dehydrogenase activity assay방법을 이용하여 측정한 결과 ethanol을 분해시키는데 필요한 효소인 alcohol dehydrogenase를 150% 활성화시키는 무줄기와 무뿌리 추출물의 농도가 각각 2.5 mg/ml와 8 mg/ml로 나타났다. 항산화력의 직접적인 지표로 대표적으로 분석되는 항목인 TBARS법에 의한 TBA 값을 천연 항산화제와 비교한 결과, 무줄기 추출물과 무뿌리 추출물(1%)은 ${\alpha}-tochoperol$(2.2%)의 43-61% 수준의 항산화 활성을 나타냈다. 이와 같은 생리활성 분석을 통하여 무를 이용한 숙취해소 및 항암 기능식품 개발, 미백 기능 소재로의 개발 가능성을 확인할 수 있었다.

게걸무 분말 4-16%를 국수 반죽에 대체${\cdot}$첨가하여 제조한 국수를 무첨가구와 비교 분석하여 게걸무 분말의 첨가가 국수의 제면특성에 미치는 영향을 조사하였다. 게걸무 분말 첨가 시, 국수의 생면과 조리면의 적색도는 게걸무 무첨가구에 비하여 유의적인 증가를 나타냈으며 이러한 경향은 첨가량이 많아질수록 높게 나타났다. 기계적 텍스처의 측정 결과, 조리면에서 게걸무 분말을 국수에 첨가 시 경도는 낮아지고 부착성과 탄성은 감소하며 씹힘성은 증가하였지만 부서짐성에는 영향을 미치지 않았다. 조리면의 무게 증가율과 부피 증가율은 게걸무 분말 첨가에 따른 차이를 보이지 않은 반면, 국물의 탁도는 게걸무 분말 첨가량이 증가할수록 국물의 탁도가 높게 나타났다. 게걸무의 첨가비율이 낮은 4-8% 수준의 시료에서는 무첨가구에 비하여 탁도가 유의적으로 감소하였다가 첨가비율이 높은 12-16% 수준의 첨가시료에서는 무첨가구 수준으로 탁도가 증가하였다. 관능검사 결과, 종합적인 기호도는 게걸무 분말을 4-8% 대체하여 첨가한 시료가 유의적으로 가장 높게 평가 되었는데, 이는 대조구 국수와 관능적 텍스처 특성이 유사하면서 무 고유의 매운맛과 시원한 맛을 나타내는 수준의 시료이었다. 따라서 국수의 제면성에 영향을 끼치지 않는 범위 내에서 국수 고유의 조직감을 유지하고 게걸무 특유의 향미를 갖는 조건은 게걸무 분말을 8% 이하로 첨가하는 것이 바람직한 것으로 판단되었다.

Development of radish collectors may enhance radish production and promote upland crop mechanization in the Republic of Korea. Theoretical analysis of power is crucial to ensure the optimum design of agricultural machinery. The aim of the present study is to analyze theoretically the power requirement of a tractor-mounted radish collector under development and to propose design guidelines. The important components of the radish collector were belt-type conveyors, three hydraulic motors, and a direct current (DC) winch motor to operate the total radish collecting process. Theoretical equations were used to calculate the hydraulic motor's power, winch motor power, and draft power at loaded and unloaded conditions. A variety of tractors (44 - 74 kW) and different soil characteristics (hard, firm, tilted, and sandy) were considered to investigate the appropriate drawbar power. Variations of the power requirement of the tractor-mounted radish collector were observed due to modifications of the design parameters. The required hydraulic power of the stem cutting conveyor, stem cutting blade, and transfer conveyor of the radish collector were 0.23 and 0.24, 0.18 and 0.19, and 0.19 and 0.22 kW under unloaded and loaded conditions, respectively. The maximum draft power was calculated as 0.89, 1.07, 1.25, and 1.61 kW at a 30° tilted angle for hard, firm, tilted, and sandy soil, respectively. The calculation showed 2.07 kW DC power was required for unfolding or folding the stem-cutting conveyor. A maximum power of 4.78 kW was prescribed for conducting the whole process of the tractor-mounted radish collector. The analysis of power introduced in this study will be helpful to select the appropriate design parameters for the successful development of a tractor-mounted radish collector.

Radish (Raphanus sativus L.) is a cruciferous vegetable, and its leaves have antioxidant and anticancer properties. This study was conducted to evaluate the effects of ethyl acetate extracts from radish leaves on hypertension in 11-week-old spontaneously hypertensive rats (SHRs). The SHRs were randomly divided into 3 groups of 6 rats each on the basis of initial systolic blood pressure (SBP) and were treated with oral administration of radish leaf extract (0, 30, or 90 mg/kg body weight [bw], respectively) for 5 weeks. Six Wistar rats were used as normotensive controls. The amount of the radish leaf extract had no effect on body weight. The SBP of the SHRs showed a decreasing trend with the consumption of the radish leaf extract. In the third week, the SBP of the group fed 90 mg extract/kg bw reduced from 214 mmHg to 166 mmHg and was significantly lower than that of the normotensive and hypertensive controls. The extract did not show a significant effect on the angiotensin-converting enzyme (ACE) activity in the serum, kidney, and lung. The extract increased the concentration of NO in serum and the activities of antioxidant enzymes such as glutathione peroxidase and catalase in red blood cells (RBCs). The serum concentrations of $Na^+$ and $K^+$ were not significantly different between all groups. However, the fecal concentrations of $Na^+$ and $K^+$ increased; the fecal concentrations of $Na^+$ and$K^+$for the normotensive and hypertensive controls were not different. Urinary excretion of $Na^+$ was higher in the normotensive Wistar rats than in the SHRs, while that of $K^+$ was not significantly different. These findings indicate that consumption of radish leaves might have had antihypertensive effects in SHRs by increasing the serum concentration of NO and fecal concentration of $Na^+$ and enhancing antioxidant activities.

Objective: This study investigated the effects of dry radish leaf and root on the quality of pork patties during refrigeration storage. Methods: The patties were divided into the following three groups: the control containing 0% dry radish leaf root powder, RL1 containing 0.5% dry radish leaf root powder, and RL2 and RL3 containing 1% and 2% dry radish leaf root powder, respectively. Proximate composition, pH, cooking loss, microbial analysis, lipid oxidation analysis, color, texture profile analysis and sensory test were performed. Results: Moisture, crude protein, and crude ash contents in RL2 and RL3 were significantly higher than those in other groups (p<0.05), whereas crude fat contents in RL2 and RL3 were significantly lower than other groups (p<0.05). Lightness was significantly lower in RL2 and RL3 than in CON (p<0.05). Cooking loss for RL2 and RL3 were significantly lower than those for the other groups (p<0.05). The pH, thiobarbituric acid levels, and total plate counts of RL2 and RL3 were significantly lower than those of CON at days 7 and 14 (p<0.05). Hardness values of RL2 and RL3 were significantly lower than those of CON, whereas chewiness values were higher than those of CON (p<0.05). In addition, the juiciness of RL2 were significantly greater (p<0.05) than those of the other groups. Conclusion: Dried radish leaves and roots improved the proximate composition and quality characteristics of pork patties, providing a basis to produce high-quality patties with extended expiration dates. Thus, dried radish leaves and roots are effective ingredients for health or functional foods.

The purpose of this study was to investigate the recognition and the perception for succession and development on Ge-Geol radish that has been grown in Icheon area. A total of 385 (male 118, female 267) aged over 20 years who lived in Icheon area were investigated from May to June 2006. Seventy five percent of the total subjects were recognized Ge-Geol radish, and only the 40.8% of them were recognized as regional special agriproduct exactly. And the rate of the subjects who had experience to eat Ge-Geol radish was just 40.8%. While preferences on Ge-Geol radish were relatively high among the subjects who have experience to eat. Reasons for liking were 'distinctive (43.8%)', 'eat from a child (24.5%)', 'tasty (15.1%)', and 'nutritious(8.3%)'. Reasons for disliking were 'rough texture (54.8%)', 'tasteless (9.7%)', 'unique smell (9.7%)', 'undesirable color (6.5%)', and 'indistinctive (6.5%)'. Also, most of the subjects considered the need for the succession and the development of Ge-Geol radish. Therefore, for expanding utilization of Ge-Geol radish, it should be contacted easily from a child and be developed as products suited to the consumer's needs by various cooking and processing methods.
