  • A linear correlation, by the stepwise multiple regression analysis, was found between the sensory test of Sigumjang aroma and the gas chromatographic data which were transformed with logarithm. GC data is the most objective method to evaluate Sigumjang aroma. A multiple correlation coefficient and a determination coefficient of more than 0.9 were obtained at the 9th and 13th steps, respectively. At step 31, the coefficient of determination level of 0.95 was attained. The accuracy of its estimation became higher as the number of the variables entered into the regression model increased. Over 90% of the Sigumjang aroma was explained by 13 compounds indentified on GC. The contributing proportion of the peak 26 was the highest followed by peaks 57 (9.27%), 29 (7.51%), 54 (6.01%), 8 (5.99%), 49 (4.97%), and 13 (4.11%).

  • Serum and liver metabolites in rats fed red ginseng (RG) were analyzed by ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry. The mass data were analyzed by partial least squares-discriminant analysis (PLS-DA) to discriminate between control and RG groups and identify metabolites contributing to this discrimination. The RG group was clearly separated from the control group on PLS-DA scores plot for serum samples, but not liver samples. The major metabolites contributing to the discrimination included lipid metabolites (lysophosphatidylcholine, acyl-carnitine, and sphingosine), isoleucine, nicotinamide, and corticosterone in the serum; the blood levels of all but isoleucine were reduced by RG administration. Not all metabolites were positively correlated with the health benefits of RG. However, the blood levels of lysophosphatidylcholine, which stimulate various diseases, and long-chain acylcarnitines and corticosterone, which activate the stress response, were reduced by RG, suggesting long-term RG might relieve stress and prevent physiological and biological problems.

  • Purpose: This study investigated the salt and sodium content of lunch meals served at foodservice center for children in Gyeongsan-si, Gyeongsangbuk-do. Methods: Five foodservice centers for children registered at Center for Children's Foodservice Management were investigated for salt and sodium content and salt content contributing rate per meal. Results: Average salt content of every meal was $1.78{\pm}0.54g$, and average sodium content was $680.99{\pm}175.97mg$. The 98 of 100 meals served in 5 foodservice centers for children exceeded the dietary reference intakes for Koreans' recommendation for adequate intake of sodium per meal of 333 mg. The highest sodium content was 1,369.85 mg. Samples from lunch meals were classified into 14 food items and investigated for one serving size, salinity, salt and sodium content. Total average salinity was 0.31%, kimchi (0.49%), followed by soup (0.45%), hard-boiled foods (0.39%), stir-fried foods (0.39%), and fresh-vegetables (0.32%). Total average salt content was 0.39 g, the most salty dishes were one-dish rice noodles, followed by soup (0.65 g), hard-boiled foods (0.49 g), stir-fried foods (0.48 g), and broth stew (0.43 g). Samples from lunch meals were classified into 6 menu groups, including cooked rice, one-dish rice noodles, soup stew, main dish, side dish, and kimchi. Contributing rate for total average salt content was high in one-dish rice noodles (48.97%), soup stew (38.47%), main dish (27.28%), side dish (21.02%), kimchi (18.56%), and cooked rice (3.95%). Conclusion: These results can be useful for reducing total dietary sodium content to less than 333 mg in children who are provided lunch meals at foodservice centers. To achieve this goal, development of low-sodium recipes, and nutrition education for foodservice employees is required.

  • The kinds of kochujang were discriminated by using their organic acid compositions, GC peak areas of volatile concentrates and flavor intensity determined by sensory evaluation. Tested kochujang were 51 kinds of traditional kochujang and 10 kinds of industry-produced kochujang in the market. The traditional kochujang included 20 kinds of Sunchang kochujang prepared with glutinous rice, 11 kinds of Boeun kochujang prepared with barley and 20 kinds of Sachun kochujang prepared with wheat. Boeun kochujang was distinguished from other kinds of traditional and industry-produced kochujang by using canonical discriminant analysis for the compositions of organic acids. Among organic acids, lactic acid was the most contributing variable for the discrimination of various kochujang. Traditional and industry-produced kochujang could be classified into 4 groups by using discriminant analysis for GC peak areas. The peak number 2, 4, 8 and 11 were found to be highly contributing variables for the discrimination of kochujang by using stepwise discriminant analysis. Industry-produced kochujang was discriminated from traditional kochujang by using canonical discriminant analysis for the intensity of 8 kinds of flavor property. The taste 'umami' was found to be the most contributing variable for the discrimination of kochujang.

  • Sodium is a necessary element for the body. Excessive intake of sodium is known as one of the risk factors for chronic diseases. Recently, increasing numbers of people in Korea are suffering from chronic diseases. Major causes of deaths were chronic degenerative disease with the rising aging population. Especially, the population of rural areas is growing older fast. In rural areas, it is known that under nutrition and high sodium intake were major nutritional problems. For sodium intake, there were some studies about contributing food items. They were not enough to show diets relate to sodium intakes. Thus, this study analyzed dishes contributing to sodium intakes of elderly living in rural areas. Dietary intakes using "the 24hour recall method" were used. For the analysis for sodium intakes, "Can-pro3.0" was used. Ranking of dishes by contributions of sodium intakes were Korean cabbage, kimchi (19.6%), seasoned soybean paste (5.3%), soybean paste (4.6%), soybean paste soup dried radish leaves (3.5%), hot pork and kimchi stew (3.4%) in order. Ranking of dish groups by sodium intakes was kimchies (28.3%), soup and hot soups (22.8%), stews and casseroles (9.7%), seasonings (8.2%),and seasoned vegetables (6.0%) in order. One-dish meals among cooked rice, wheat noodles among noodle and mandu, soups using the soybean paste, stews using soybean paste and kimchi, salted fish among grilled foods, stir-fried anchovy among stir-fried foods, seasoned spinach, and Korean cabbage kimchi contributed to sodium intakes. As the nutrition deficiency of the elderly living in rural areas could be a problem, and excessive sodium intakes is threatening to their health, it is needed for the senior citizens to have adequate knowledge for diets containing less sodium. And recipes for healthy food and nutrition education based on their diets are needed.

  • Objectives: Calcium (Ca) is an insufficiently consumed nutrient, whereas phosphorus (P) intake has exceeded the recommended intake level in Korea over the past decade. The purpose of this study was to analyze dietary Ca and P intakes and their contribution rate according to dish groups. Methods: A 24-hour dietary recall survey of 640 healthy adults (aged 19-69 years) was undertaken twice in four Korean provinces. Dietary Ca and P intakes and their rates of contribution from 31 major dish groups were analyzed and compared by gender, age group, and region. Results: The average Ca and P intakes of the subjects were 542.1 ± 222.2 mg/d and 1,068.3 ± 329.0 mg/d, respectively. The intakes of Ca and P as percentages of recommended nutrients intake (RNI%) were 71.7 ± 29.8% and 152.6 ± 47%, respectively, and the percentages under the estimated average requirement were 60.3% for Ca and 3.8% for P. The RNI% of Ca was not significantly different between males and females, but was significantly higher in subjects in the sixties age group than in other age groups and was significantly lower in the Korean capital than in other regions. The RNI% of P did not significantly differ by gender or age groups, but it was significantly higher in the capital than in Gyeong-sang. The five major dish groups contributing to Ca intake (contribution rate) were milks/dairy products 69.2 ± 109.2 mg/d (12.6%), soups 55.6 ± 69.6 mg/d (10.1%), stir-fried foods 53.1 ± 70.7 mg/d (9.7%), stews 43.4 ± 85.4 mg/d (7.9%), and kimchi 38.4 ± 31.8 mg/d (7.0%). The five major dish group contributing to P intake (contribution rate) were cooked rice 160.7 ± 107.1 mg/d (14.9%), stir-fried foods 88.5 ± 89.4 mg/d (8.2%), soups 76.7 ± 85.8 mg/d (7.1%), one-dish meals 63.3 ± 94.4 mg/d (5.9%), and stews 62.6 ± 89.3 mg/d (5.8%). The dish groups contributing to Ca and P intakes differed somewhat by gender, age group, and region. Conclusions: Programs to improve the nutritional status of Ca and P intakes should consider the differences in Ca and P contribution rates by dish groups as well as by gender, age group, and region.

  • BACKGROUND/OBJECTIVES: Magnesium is an essential nutrient for human health. However, inadequate intake is commonly reported worldwide. Along with reduced consumption of vegetables and fruits and increased consumption of refined or processed foods, inadequate magnesium intake is increasingly reported as a serious problem. This study aimed to assess magnesium intake, its dietary sources, and the adequacy of magnesium intake in Korean populations. SUBJECTS/METHODS: Data was obtained from the Korea National Health and Nutrition Examination Survey 2016-2019 and included individuals aged ≥1 yr who had participated in a nutrition survey (n=28,418). Dietary intake was assessed by 24-h recall, and dietary magnesium intake was estimated using a newly established magnesium database. Diet adequacy was evaluated by comparing dietary intake with the estimated average requirement (EAR) suggested in the Korean Dietary Reference Intakes 2020. RESULTS: The mean dietary magnesium intake of Koreans aged ≥1 yr was 300.4 mg/d, which was equivalent to 119.8% of the EAR. The prevalence of individuals whose magnesium intake met the EAR was 56.8%. Inadequate intake was observed more in females, adolescents and young adults aged 12-29 yrs, elders aged ≥65 yrs, and individuals with low income. About four-fifths of the daily magnesium came from plant-based foods, and the major food groups contributing to magnesium intake were grains (28.3%), vegetables (17.6%), and meats (8.4%). The top 5 individual foods that contributed to magnesium intake were rice, Baechu (Korean cabbage) kimchi, tofu, pork, and milk. However, the contribution of plant foods and individual contributing food items differed slightly by sex and age groups. CONCLUSIONS: This study found that the mean dietary magnesium intake among Koreans was above the recommended intake, whereas nearly one in 2 Koreans had inadequate magnesium intake. To better understand the status of magnesium intake, further research is required, which includes the intake of dietary supplements.

  • The article analyzes the impact of factors affecting the environmental accounting of enterprises in the food and beverage industry in Vietnam, providing more empirical evidence on factors affecting environmental accounting. The research method uses a questionnaire survey of managers at all levels, chief accountants, and cost accountants, of 56 enterprises in the food and beverage industry. The survey results collected 268 questionnaires. After eliminating the invalid questionnaires due to many blank cells, the author chose to use 236 questionnaires. Quantitative research was carried out with SPSS 25 software. Research results show that all 6 factors positively affect environmental accounting, which includes Firm size, Stakeholders, Awareness/Knowledge of leaders, financial resources, Qualifications of staff, and Regulations, in which stakeholders and leaders' perceptions are the most influencing factors. Based on the research results, the author has proposed recommendations to improve the ability of enterprises to successfully implement environmental accounting in the food and beverage industry, thereby contributing to improving the operational efficiency of the food and beverage enterprises. The Vietnamese market is very potential, so the Government, authorities, customers, investors, etc., contribute to creating significant pressure to implement environmental accounting in food and beverage enterprises.

  • The purpose of the present study is to investigate the correlations between food intake behavior and job stress level and neuropeptide hormone concentrations. Job strain and food intake behavior were first identified using a self-reported questionnaire, concentrations of neuropeptide hormones (adiponectin, brain derived neurotrophic factor [BDNF], leptin, and ghrelin) were determined, and the correlations were analyzed. In the results, job strain showed significant correlations with adiponectin (odds ratio [OR], 1.220; 95% confidence interval [CI], 1.001~1.498; p < 0.05) and BDNF (OR, 0.793; 95% CI, 0.646~0.974; p < 0.05), and ghrelin exhibited a significant correlation with food intake score (OR, 0.911; 95% CI, 0.842~0.985, p < 0.05). These results suggest that job stress affects food intake regulation by altering the physiological concentrations of neuropeptide hormones as well as emotional status.
