마늘종의 가공, 조리 특성과 관련한 기초자료를 확보하고자 데치기 시간(30초, 1분, 2분, 3분, 4분)을 달리한 남해산 마늘종의 색도, 물성, 총당, 비타민 C, 클로로필, 총 폴리페놀, 플라보노이드, 총 피루베이트 및 티오설피네이트 함량을 분석하였다. 데치기 시간이 길어질수록 마늘종의 색은 L 값은 감소하였으며, a값은 점차 증가하는 경향을 보였다. 그리고 황색도를 나타내는 b값은 $12.48{\pm}2.67{\sim}15.08{\pm}1.55$의 범위로 데치지 않은 마늘종에 비해 유의적으로 낮았다. 생마늘종의 경도는 $2431.19{\pm}95.44g$이었는데, 데치기 시간의 증가와 더불어 감소하였다. 데침 시간을 달리한 마늘종의 총당과 비타민 C의 함량은 데치지 않은 마늘종에 비해 유의적으로 낮았고 데치기 시간에 따라 점차 감소하였는데 이는 조리용수로 용출되거나 열에 의해 파괴되었다고 생각된다. 총 클로로필의 함량은 $79.49{\pm}2.46{\sim}106.97{\pm}9.69{\mu}g/g$이었으며, 청록색을 나타내는 클로로필 a가 황녹색을 나타내는 클로로필 b에 비해 약 2.6~4.1배 더 많이 함유되어 있고 데침 시간이 길어질수록 점차 총량이 감소하였다. 총 피루베이트 및 티오설피네이트 함량은 데치는 과정을 거치는 동안 약 50% 수준으로 감소하였다. 마늘종은 데치기 처리 시간에 따라 색도, 물성 및 주요 성분이 감소되므로 2분 정도로 데침 처리 하는 것이 마늘종 고유의 성분과 품질을 유지하는데 적합한 것으로 판단된다.

The purpose of the study was to investigate the effects of dietary green tea catechin and vitamin E on the phospholipse {TEX}$A_{2}${/TEX} activity and th antioxidative defense system in streptozotocin (STZ)-induced diabetic rats. Sprague-Dawley male rats weighing 100$\pm$10 gm were randomly assigned to one normal and five STZ-induced diabetic groups. The diabetic groups were assigned either a catechin-free diet (DM group), 0.5% catechin diet (DM-0.5C group), 1% catechin diet (DM-1C group), vitamin E-free diet (DM-0E group), and 400 mg vitamin E per kg diet (DM-400E group) according to the levels of dietary catechin or vitamin E supplementation. The vitamin E levels of the normal, DM, DM-0.5C, and DM-1C groups were 40 mg per kg diet. Diabetes was experimentally induced by an intravenous injection of streptozotocin after 4 weeks of feeding the five experimental diets. The animals were sacrificed on the 6th day of he diabetic state. The body weight gains were lower in all five diabetic groups after the STZ injection. The platelet phospholipase {TEX}$A_{2}${/TEX}({TEX}$PLA_{2}${/TEX}) activity in the diabetic groups was higher than that in the normal group. However, the enzyme activity in the DM-0.5C, DM-1C, and DM-400E groups was lower than that in the DM and DM-0E groups. The cytochrome {TEX}$P_{450}${/TEX} and cytochrome {TEX}$b_{5}${/TEX} content and NADPH-cytochrome {TEX}$P_{450}${/TEX} reductase activity were about 50~110% higher in the DM and DM-0E groups than in the normal group, yet significantly reduced by either catechin or vitamin E supplementation. The superoxide dismutase (SOD) content in the liver did not differ significantly in any of the groups. However, the glutathione peroxidase (GSHpx) activity was generally lower in the diabetic groups, compared with the normal group, whereas that of the DM-0.5C, DM-1C, and DM-400E groups was significantly higher compared with that of the DM and DM-0E groups. The levels of thiobarbituric acid reactive substances (TBARS) in the liver tissue were 148% and 201% higher in the DM and DM-0E groups, respectively, compared with the normal group, however, these levels were reduced by either catechin or vitamin E supplementation (DM-0.5, DM-1C and DM-400E). Accordingly, the present results indicate that STZ-induced diabetic rats exhibited an imbalance between free radical generation and scavenger systems in the liver which led to the acceleration of lipid peroxidation. However, these abnormalities were reduced and the antioxidative defense system was restored by either dietary catechin or vitamin E supplementation. In conclusion, the effects of dietary catechin or vitamin E in streptozotocin-induced diabetic rats would appear to inhibit lipid peroxidation as an anti-oxidant by regulating the activity of {TEX}$PLA_{2}${/TEX}.

This study was performed to assess the nutritional status and hair mineral content of children with behavioral problems and compare the values with a gender, age-matched control group. The subjects were recruited from S elementary school children in Seoul, Korea. Students scored higher than 60 points were diagnosed with behavioral problems according to the Korean-Child Behavior Checklist. Nutritional assessment of the two groups (behavior problem group: male n=15, female n=24; $9.6{\pm}1.6$ years, control group: male n=16, female n=18; $9.5{\pm}1.9$ years) was performed using a nutritional survey and by measuring hair mineral contents. In the results, food frequency questionnaire analysis showed that the intakes of anchovy (P<0.05), soybean curb (P<0.01), radish (P<0.05), bean sprouts (P<0.05), spinach (P<0.05), carrot (P<0.05), pumpkin (P<0.05), lettuce (P<0.05), cabbage (P<0.01), apple (P<0.05), and milk (P<0.01) were higher in the control group than the behavior problem group, whereas intakes of ramyeon (P<0.05), cookies (P<0.05), and coke (P<0.01) were higher in the behavior problem group than the control group. Intakes of most nutrients such as plant-derived protein (P<0.05), fiber (P<0.05), plant-derived calcium (P<0.05), phosphorus (P<0.05), plant-derived iron (P<0.05), vitamin B2 (P<0.05), vitamin B6 (P<0.05), vitamin C (P<0.01), vitamin E (P<0.05), and folate (P<0.05) were significantly higher in the control group than the behavior problem group. Hair analysis showed that the levels of arsenic (P<0.05), mercury (P<0.001), uranium (P<0.05), iron (P<0.001), boron (P<0.01), and germanium (P<0.001) were lower, but the levels of phosphate (P<0.05), chromium (P<0.001), sodium (P<0.05), and sulfur (P<0.001) were higher in the behavior problem group than the control group. Conclusively, behavioral problems constitute a complicated condition in which nutritional factors may play major roles. However, it is still under investigation as to whether or not modification of dietary habits or nutritional supplementation can improve children's behavior, since symptoms require a broad understanding of the environmental and genetic interactions.

Kimchi cabbage is widely consumed in Korea, with the popularity of this pickled vegetable dish growing internationally due to its health benefits. In this study, the physical (size, color), functional (antioxidant activity, total polyphenol, and flavonoid content), and nutritional (water- and fat-soluble vitamins) characteristics of two new kimchi cabbage varieties, namely red and gold kimchi cabbages (RKC and GKC, respectively), were analyzed and compared with those of the common kimchi cabbage (CKC). There were no significant differences in the thickness or length of the three kimchi cabbages, although RKC had the narrowest outer leaves among the three varieties (11.94 cm). Regarding chromaticity, yellowness was highest in GKC (29.86), whereas redness was highest in RKC (9.31). Furthermore, RKC had the highest recorded vitamin B₆ and B₉ (1,288.5 ㎍/100 g and 776.7 ㎍ dietary folate equivalent/100 g, respectively). On the other hand, the fat-soluble vitamins vitamin A (β-carotene) and K (Phylloquinone) were both highest in GKC (907.1 ㎍/100 g and 712.2 ㎍/100 g, respectively). Generally, all kimchi cabbage samples contained high levels of vitamin E (1.8-4.9 mg α-tocopherol equivalent/100 g). RKC attained the highest antioxidant activity and total polyphenol and total flavonoid contents among the three kimchi cabbages. These results show that gold and red kimchi cabbage can be used as raw materials in the food-processing industry.

In this study, the thermal treatment yam (Dioscorea batatas DECNE.) was analyzed for its proximate and nutritional compositions including mineral, vitamin, amino acids and fatty acids. Thermal treatment yam is mainly consisted of carbohydrate (70.3%) with small amounts of crude protein (15.8%), crude ash (5.1%) and crude fat (1.6%). It was found to be a good source of essential minerals such as K (1100.2 mg/100 g), Mg (99.4 mg/100 g), Ca (54.8 mg/100 g) and Na (44.9 mg/100 g) but Zn (4.8 mg/100 g) and Fe (0.2 mg/100g) content was low. Little amounts of vitamin E (8.3 mg/100g), vitamin C (3.5 mg/100g) and vitamin B1 (2.1 mg/100g) could be found. The amino acid analysis revealed that the yam was superior with respect to serine (1454.2 mg%), lysine (684.6 mg%) and histidine (684.6 mg%). Essential amino acids were calculated to be 2849.3 mg%. The amino acid profiles showed that thermal treatment yam is limiting in isoleucine and phenylaline. Linoleic acid was the most predominant fatty acids with the value of 47.3% followed by palmitic acid (24.7%) and oleic acid (12.7%). And the unsaturated fatty acids including oleic acid and linoleic acid were present in big quantities in thermal treatment yam.
