This study was conducted to investigate weight control status and associated factors among health-related major female college students. The subjects consisted of 41 nutrition and 78 physical exercise major female college students. Nutrient intakes, biochemical index, nutrition knowledge (recognition and accuracy), interest of weight control, body satisfaction, self-recognition of health condition, self-evaluated body weight were studied. About 73% of nutrition and 79% of physical exercise major female students were in the normal range of BMI ($18.5{\sim}23$) and 2% of nutrition and 1% of physical exercise major female students were underweight, 10% of nutrition and 6% of physical exercise major female students were obese. There were no significant differences in height and weight by major but %body fat and WHR in physical exercise majors were significantly lower than nutrition major students (respectively p<0.01, p<0.05). Overall, nutrition intakes of subjects were not shown to be appropriate, especially Ca/P of subjects was shown $0.54{\sim}0.64$, fat% out of energy of subjects was shown $24.7{\sim}29.0$ and Na intake was shown above 2000mg. Recognition and accuracy of nutrition were higher than those of physical exercise majors (p<0.001). There were no significant differences in self-recognition of health condition, self-evaluated body weight, satisfaction of body shape by major and weight control attempt. But interest of weight control of attempter was higher than that of no-attempter in nutrition (p<0.05) and physical exercise major students (p<0.01). Significantly negative correlation was found in satisfaction of body and BMI, body fat mass, %bodyfat, WHR. And significantly positive correlation was found in interest of weight control and BMI, %bodyfat, WHR. It was noticeable to see that interest of weight control was positively correlated to accuracy and accuracy was negatively correlated to blood cholesterol level. Therefore, proper nutrition education for female college students is needed in order to improve their weight control-related health.

Centella asiatica (C. asiatica) has been widely used in food, cosmetics, and pharmaceutical industry as a functional material. In a previous study, we have investigated not only pharmacological effects such as antioxidative and anti-inflammatory effects, but also analyzed various functional ingredients. In this study, triterpenoids were analyzed using HPLC-DAD to determine marker compounds among functional ingredients. When triterpenoids were analyzed, asiaticoside from C. asiatica was determined as an optimal marker compound. Next, specificity, linearity, limited of detection (LOD), limited of quantification (LOQ), precision, accuracy, and range were evaluated using HPLC-DAD to determine asiaticoside contents in C. asiatica juice and extracts. The specificity was elucidated by chromatogram and retention time using an established analytical method. The coefficient of correlation obtained was 0.9996. LOD was 4.99 ㎍/mL and LOQ was 15.12 ㎍/mL. Intra- and inter-day precision of asiaticoside were determined to be 0.48~1.68% and 0.08~1.09%, respectively. Furthermore, the recovery rate of asiaticoside was 98.88% and the analytical range of Field-70E was determined to be 0.625~10 mg/mL. As a results of evaluating ABTS, DPPH, and FRAP antioxidative effect, Field-70E showed potent antioxidant activities. Results of this study could be used as basic data for quality standardization of C. astiatica juice and extracts.

The identification of bacteriophage proteins on the surface of Lactobacillus rhamnosus Pen was performed by LC-MS/MS analysis. Among the identified proteins, we found a phage-derived major tail protein, two major head proteins, a portal protein, and a host specificity protein. Electron microscopy of a cell surface extract revealed the presence of phage particles in the analyzed samples. The partial sequence of genes encoding the major tail protein for all tested L. rhamnosus strains was determined with specific primers designed in this study. Next, RT-PCR analysis allowed detection of the expression of the major tail protein gene in L. rhamnosus strain Pen at all stages of bacterial growth. The transcription of genes encoding the major tail protein was also proved for other L. rhamnosus strains used in this study. The present work demonstrates the spontanous release of prophage-encoded particles by a commercial probiotic L. rhamnosus strain, which did not significantly affect the bacterial growth of the analyzed strain.

The purpose of this study was to investigate the consumption status and perception of soy meat among university students and to compare their sensory evaluations of commercial meatballs and soy meatballs. The subjects were students at a university who were grouped into those majoring in food and nutrition and those not majoring in the subject. The results of the two groups were compared. The main sources through which the students became aware of meat analogs were examined. The food and nutrition major students were about three times more likely to learn about meat analogs through 'education', and those not majoring in the subject were about four times more likely to learn about them from the social media (P<0.01). The most common reason for having tried soy meat was 'curiosity' and that for not eating it was 'no opportunity'. Without significant differences between groups, the most common answer for questions relating to the product that they had eaten was 'Ramen flakes' (30.5%) and the most common answer for the routes for eating the product was in the order of: 'restaurants' (36.6%)>school lunches (24.9%)>large and medium-sized supermarkets (22.8%). The most common answer to the question inviting suggestions on 'improvement points to promote the consumption of soy meat' was 'taste'(19.2%), followed by 'product promotion' and 'reasonable price'. About half of the subjects failed to differentiate the soy meatballs from regular meatballs before the sensory test and 21.3% after that. The difference in the sensory test scores of the two types of meatballs with respect to 'texture' was significantly higher for the major students than for the non-major students (P<0.05). These results could provide basic information that could enable the promotion of soy meat.

The purpose of this study was to investigate the antioxidative effect and quality characteristics of cookies made with Sea tangle powder(STP). The cookies were at $30^{\circ}C$ for 45 days. The 3% STP had higher pH value compared to the other groups and control. As more STP was added, the L-value and b-value decreased, and the a-value increased for the color values. The results of sensory evaluation and acceptance test showed that the cookies with 3% STP was significantly more preferable in overall acceptability than the others. The acid value, peroxide value, and thiobarbituric acid value were lower in cookies with 3% and 6% STP than in those cookies made 9% STP and the control cookies.

This study aimed to estimate daily intake of anthocyanins and to identify major sources of anthocyanins in current Korean dietary patterns in order to implement dietary recommendations for the improvement of Korean health. Sixteen foods were selected based on the availability of food intake and reliable anthocyanin content. Food intake data from the Korea National Health and Nutrition Examination Survey 2014 and anthocyanin content data from earlier investigations were used to calculate the consumption of anthocyanins. Anthocyanin contents of 16 foods varied significantly and exhibited a range of 0~4,009 mg/100 g of fresh weight. Daily intake of anthocyanins was estimated to be 3.3 mg to 95.5 mg in Koreans. Of the 16 foods studied, the source contributing most to anthocyanin intake in the Korean population was plums (35.1%), followed by black beans (17.1%) and grapes (15.2%). These results indicate that major foods contributing to anthocyanin consumption in the Korean dietary pattern are fruits and grains.

BACKGROUND/OBJECTIVES: Excess intake of dietary sodium, either directly or indirectly, increases the risk of several diseases, including cardio-cerebral vascular diseases such as stroke and hypertension. Excessive sodium intake and increased prevalence of hypertension have emerged as major issues worldwide. Therefore, the present study evaluated the recent trends in dietary sodium intake and the food sources of sodium intake in the Korean population using the Korea National Health and Nutrition Examination Survey (KNHANES, 2013-2017) data. SUBJECTS/METHODS: This study used the one-day 24-h recall dietary intake survey data from the 2013-2017 KNHANES to determine the average daily sodium intake by sex and age and the main dishes and food groups contributing to the dietary sodium intake. RESULTS: The mean sodium intake range was 3,477.2-3,889.6 mg/day during 2013-2017. The major food groups contributing to sodium intake were seasonings (1,597.5-1,870.5 mg/day), vegetables (680.4-756.7 mg/day), and cereal and grains (573.2-609.4 mg/day). Noodles and dumplings (536.7-573.2 mg/day), kimchi (487.3-539.6 mg/day), and soups (367.6-428.9 mg/day) were the top three dish groups that contributed to the sodium intake. In these dishes, the major sources of sodium intake were ramyeon (age groups 10-18 and 19-29 yrs), baechukimchi (age groups 40-49 and 50-59 yrs) and doenjang-kuk (age groups 60-69 and ≥ 70 yrs), respectively. CONCLUSIONS: In summary, reducing the consumption of soups and kimchi is an effective way to reduce sodium intake. Personalized nutrition education on dietary sodium intake management is required because of the different food sources contributing to the sodium intake according to the subjects' age.

This study was performed to investigate the nutrition knowledge, attitudes, and dietary habits of physical education (PE) major and non-majors of male college students. The subjects were 253 students residing in Gyeonggi area. Nutrition knowledge scores of PE major students were lower than that of non-major students. Both PE major and non-major students reported TV, radio, and internet as their primary sources of nutrition information. Overall dietary attitude scores of two groups did not differ significantly, but PE major students showed more positive attitudes than non-major students for 'Enjoy eating foods that are good for health'. PE major students took more number of meals a day and took more irregularly than non-major students. Also they used more nutrient supplements than non-major students. PE major students drank more amounts of alcohol and drank more frequently than non-major students. But the smoking status of the two groups was not significantly different. PE major students scored higher than non-major students in dietary habits on balance of meals in spite of their low nutrition knowledge scores. Therefore, it is suggested that nutritional programs for PE major and non-major college students should be developed. (Korean J Community Nutrition 14(4) : $363{\sim}373$, 2009)

Objectives: The study examined the status on the use of nutrition labeling and nutrition claims among university students as well as the diet quality and nutritional status using the nutrition quotient (NQ) according to the use of nutrition labeling and claims. Methods: A cross-sectional survey was conducted on university students (86 males and 131 females) from March to April in 2019 in Chungbuk area. Results: The percentage of subjects who reported that they recognized nutrition labeling was 80.2% of the total, and 63.8% of them indicated that they used nutrition labeling for their food choices. In addition, 22.6% of the total subjects said that they used nutrition claims. The group of subjects using nutrition labeling showed significantly higher mean scores in balance (P < 0.01), diversity (P < 0.05), moderation (P < 0.01), and dietary behavior (P < 0.001) along with higher mean NQ score (P < 0.001) compared to the group not using nutrition labeling. The group using nutrition claims had significantly higher mean scores in balance (P < 0.001), diversity (P < 0.01), moderation (P < 0.001), and dietary behavior (P < 0.001) as well as total NQ scores (P < 0.001) compared to the group not using nutrition claims. The group of subjects using both nutrition labeling and nutrition claims showed significantly higher mean NQ scores than the group of subjects using either nutrition labeling or nutrition claims (P < 0.05). Conclusions: In this study, university students' use of nutrition labeling and nutrition claims appeared to be related to their diet quality and nutritional status.
