This study aimed to investigate the activities of phytochemical and bioactive components from 24 new varieties of red pepper obtained by crossbreeding different Korean red pepper lines. The ASTA (American Spice Trade Association) color values ranged from 116.69 to 249.83 and the total carotenoid content ranged from 3.19 to 6.11 mg/g dried red pepper. The free sugar content ranged from 43.41 to 199.54 mg/g, and the fructose content was found to be higher than the glucose content. The ascorbic acid, total polyphenol, and flavonoid contents were found to be 8.08-11.53 mg/g, 7.93- 14.26 mg gallic acid/g, and 4.24-10.07 mg quercetin/g dried pepper, respectively. Overall, the total polyphenol contents of the new varieties were found to be higher than the average content of Korean red peppers. The total capsaicinoid content in the new varieties varied widely from 0.42 to 237.87 mg/100 g dried pepper. The pepper-methanol extract antioxidant activities of 'variety 2, 4, 8, 9' were higher than others. A high correlation was observed between the antioxidant activities and the polyphenol contents (r=0.804, r=0.701). © The Korean Society of Food Science and Technology.

Gold@platinum (Au@Pt) nanostructures exhibit desirable catalytic abilities and unique optical properties, which are not seen in single-component metal nanoparticles (NPs). To date, however, there is only limited information available in the literature on the integrated approach to investigate the antioxidant activities of Au@Pt NPs. The aim of the present study, was to evaluate the antioxidant activities of hybrid nanorods, i.e., Au@Pt NPs. Specifically, the free radical scavenging effect, hydroxyl radical scavenging activity, and superoxide dismutase (SOD)-like activity of Au@Pt NPs were examined. Furthermore, the in vitro antioxidant ability of Au@Pt NPs was assessed by measuring the cell viability of V79-4 (Chinese hamster lung fibroblasts), PC-3 (human prostate cancer), and MCF-7 (human breast cancer) cells under oxidative stress induced by hydrogen peroxide (H2O 2). The results showed that Au@Pt NPs exhibited high DPPH radical scavenging activity, non-site specific hydroxyl radical scavenging activity, linoleic acid peroxidation inhibitory ability by TBA tests in a low Au@Pt NP concentration range. Furthermore, in vitro experiments revealed that Au@Pt NPs showed cellular protection against oxidative stress induced by H 2O2. © 2014 the Partner Organisations.

The aim of our study was to investigate the chemical composition of the Asian ginseng seed (Panax ginseng C.A. Meyer) and the American ginseng seed (Panax quinquifolium L.) grown in Korea (3 years, KGS3; 4 years, KGS4), China (4 years, CGS4), and USA (4 years, AGS4). AGS had the heaviest 100-seed weight (4.21±0.31 g). The approximate compositions of the ginseng seeds were 13.66-17.00% crude protein, 2.21-8.65% crude ash, 19.06-24.06% crude lipid, and 43.21-47.49% crude fiber. The mineral contents of the ginseng seeds were greater in order of K>P>Ca>Mg>Fe>Na>Zn >Cu. The unsaturated fatty acid content was 96.71-96.94%, and the major fatty acids oleic acid and linoleic acid were present. Total sugar content was 15.00-26.17 mg glucose/g. The acidic polysaccharide content was 0.56-0.80 mg β-Dgalacturonic acid/g. These results showed the differences in the physicochemical characteristics of ginseng seeds with respect to cultivation location, cultivation year, and species.

This study aimed to determine the quality characteristics of ginseng seed oil as well as evaluate the efficacy of ginseng seed oil as a food resource. Ginseng seed oil was obtained by different extraction methods; from solvent extraction oil, supercritical fluid extraction oil, and screw pressed extraction oil. Total unsaturated fatty acids were present at 97.72~97.92%. Oleic acid (80.13~81.16%) was the highest, followed by linoleic acid (14.98~15.69%). The total phenol content (mg gallic acid equivalent/100 g oil) was higher in screw pressed extraction oil (56.32±1.47) compared to others. γ-Tocopherol was only present in ginseng seed oil and screw pressed extraction oil showed the highest levels of γ-tocopherol (5.95±0.25 mg/100 g oil) among the tested samples. Screw pressed extraction oil showed the greatest oxidative stability with an induction time of 16.58 hours. Acid values and peroxide values of ginseng seed oil increased with increasing storage period. The total phenol and γ-tocopherol contents were higher in screw pressed extraction oil than in other ginseng seed oils, which suggests that screw pressed extraction oil has the greatest oxidative stability.

This study compared obese childrens food group intakes with the new Dietary References Intakes for Koreans (KDRIs) food guides for 5th-6th grade school children. This study also determined the extent of sedentary life styles related with obesity in this area of children. This is a cross-sectional study of 799 school children. The dietitian sent a survey form describing the project and a questionnaire to the subjects family. The questionnaire included child demographics, family history of chronic diseases, the daily servings of five food groups, such as grains, meat and beans, dairy products, fruits, and vegetables. The daily or weekly hours of physical activity, television viewing, and computer usage were also surveyed. Obesity index (%) of the subjects was calculated, and children with an obesity index (%) equal to or greater than 20 were classified as the obese. Among the 799 participants, 50.7% were female. The percentages of the normal and the obese were 691 (86.5%) and 108 (13.5%) respectively. Obese children reported eating less vegetables (p<0.05), more high sugar snacks (p<0.05), and high fat snacks (p<0.05) than normal children. No significant differences in food servings of grains, meats and beans, and fruits, and dairy products between the normal and the obese were shown. Obese children reported fewer hours of physical activities (p<0.05) and more hours of computer usage (p<0.05) than normal children. Girls showed less likelihood of being obese (odds ratio, 0.575, CI (0.38, 0.87), p<0.05). More hours of physical activity significantly decreased the likelihood of being obese (odds ratio, 0.572, CI (0.35, 0.92), p<0.05). Family history of obesity almost doubled the likelihood of obesity in children (odds ratio, 2.653, CI (1.660, 4.241), p<0.05). In conclusion, frequent snacking, inadequate vegetable consumption, and sedentary lifestyle increased significantly the likelihood of obesity in children, which suggest that obesity intervention in this age group should focuse more on those variables.

The purpose of this study was to assess the relationship between the mothers interest in weight control and its association with the preschoolers obesity and weight related concerns. This was a cross-sectional study based on 470 parents self-reports. To score interests in weight control, mothers rated each of 6 items on a five-point Likert scale ranging from disagree (1) to agree (5). The perceptions of mothers weights and their childrens weights, mothers Body Mass Index (BMI), preschoolers Weight-Length Index (WLI) (%), and weight-related concerns were determined. The mothers BMI was significantly correlated with interest scores of weight control in mothers (r=0.632, p<0.001) while their childrens obesity was weakly correlated with the mothers interest scores (r=0.133, p=0.025). Mothers with a high interest of weight control reported higher percentages of family history of obesity than mothers with lower interests (63.2% vs. 36.8%, p<0.001). Two-thirds of the mothers (65.4%) were accurate in their perceptions about their weights. Similarly, 63.7% of mothers knew exactly their childrens weight-statuses. Compared with mothers with low interest in weight controls, mothers with high interest in weight control had lower correct-perceptions about their weights (p<0.05) but higher correct-perceptions about their childrens weights. More than two-thirds of mothers (85%) reported not worrying about their childrens obesity in the future. Only 14.3% of the mothers were satisfied with their current weight statuses. Three-fourths of mothers preferred exercise as an effective weight-control method for their children, 20% preferred diet therapy and 5.5% preferred behavior modification. More girls were overweight / obese, than boys (overweight: 16.1% (girl) vs. 12.8% (boy), obese: 5.4% (girl) vs. 4.5% (boy)). About 40% of overweight girls mothers had low interests in their weight controls with low correct-perceptions in their childrens weights, which suggests possible elevated risk of obesity, especially in girls, in the future.
