The purpose of this study was to analyze the motives for food choice using a Food Choice Questionnaire (FCQ). A FCQ, an instrument that measures the reported importance of nine factors underlying food choice, was administered to a representative sample of 157 adult respondents from 21 to 27 October 2013. Statistical analyses such as Descriptive statistics, Factor analysis, Reliability analysis, Pearson correlation, independent samples t-test, and analysis of variance (ANOVA) were performed on the data using the SPSS PASW Statistics 18.0 for Windows. According to the results, five food choice motivation factors were discerned: health, sensory and mood, convenience, price, and familiarity. The most important factors reported were price, sensory and mood, convenience, health and familiarity. We found that food choice motivation is distinguished by age, frequency of eating out, and consumption of HMR. Females in this study gave higher importance scores to health, sensory and mood, and familiarity. There were higher correlations between 'health' and 'sensory appeal and mood'.

The purpose of this study was examine the health and food intakes of industrial workers who worked day and night. The questionnaire asked them about their health, stress, knowledge of nutrition, food habits, food intakes and frequency. The night-time workers had a stomachache compaired with day-time workers. Male day-time workers were more prone to stress than night-time workers in the area of job. In the areas of nutritional knowledge and food habits, there were no significant differences between day-and night-time workers for both male and female. Intakes of rice, bread, noddle, meat, fish. beans, vegetables in night-time workers were less than day-time workers. Also the male night-time workers consumed more milk and carbonated drinks than the day-time workers. The night-time workers were worse than the day-time workers and the female night-time workers were the worst. Considering the above results, the night-time workers should correct their food habits and have a well-balanced diet.

Ephedra is a genus of the Ephedraceae family and is found in temperate regions, such as Central Asia and Europe. Among the various ephedra species, Ma Huang (Ephedra herb) is derived from the aerial parts of Ephedra sinica S tapf, Ephedra equisetina Bunge, and Ephedra intermedia Schrenk & C.A. Mey. Ma Huang contains various ephedra alkaloids, including (-)-ephedrine, (+)-pseudoephedrine, (-)-norephedrine, (+)-norpseudoephedrine, (-)-methylephedrine, and (+)-methylpseudoephedrine, which are found naturally as single enantiomers, although they can be prepared as racemates. Although the use of Ma Huang in foods is prohibited in Korea, products containing Ma Huang can be imported, and so it is necessary to develop a suitable analytical technique for the detection of Ma Huang in foods. Herein, we report the development of analytical methods for the detection of ephedra alkaloids in products containing Ma Huang. Following sample purification by solid phase extraction, quantitative analysis was performed using ultra-performance liquid chromatography-triple quadrupole mass spectrometry (UPLC-MS/MS). Additionally, the enantiomers were successfully separated using HPLC-DAD. We successfully analyzed various food samples, where the ephedra alkaloids were qualitatively and quantitatively determined, and the enantiomers were separated. It is expected that these methods may contribute toward preventing the distribution of illegal products containing Ma Huang.

Purpose: This study investigated knowledge of atopic dermatitis and food allergies, as well as health information literacy, among North Korean refugee mothers with preschool-age children and explored how these variables were related to participants' characteristics. Methods: A descriptive study design was used. Data from 130 North Korean refugee mothers were collected between January and March 2023. Results: The mean scores were 14.48 of 30 for atopic dermatitis knowledge; 2.77 of 10 for food allergy knowledge, and 56.95 of 80 for health information literacy. Significant differences were observed in knowledge of atopic dermatitis based on breastfeeding duration (F=4.12, p=.009), and in knowledge of food allergies based on mixed feeding (F=3.11, p=.049). Health information literacy showed significant relationships with education level (F=3.76, p=.026), occupation (F=3.99, p=.021), checking nutritional information (t=2.91, p=.004), mixed feeding (F=4.50, p=.014), and atopic dermatitis diagnosis (t=6.86, p=.001). Significant positive correlations were observed between atopic dermatitis knowledge, food allergy knowledge, and health information literacy. Conclusion: Personalized educational programs should be implemented to improve awareness of allergies and health information literacy among North Korean refugee mothers, which would help them find, evaluate, and understand health-related information. These programs should focus on providing nutrition and dietary education to promote healthy growth in children and prevent diseases.

The purpose of this study was to investigate factors influencing sales of health functional foods by door-to-door saleswomen. A total of 450 women who worked as door-to-door salespersons in Seoul were enrolled. The survey questionnaire was composed of five parts as follows: general characteristics, factors related with door-to-door sales process, task education, competency required for door-to-door salespersons, and customer relationship beliefs. The survey was conducted in October 2011. Finally, data on 302 subjects were statistically analyzed using the SPSS 17.0 package program. Reason for sales of health functional foods (p<0.01), time required for sales promotion (p<0.001), difficulties during sales of health functional foods (p<0.05), satisfaction of task education (p<0.01), and failure of salesperson's memory as problems of task education (p<0.01) were significantly associated with sales of health functional foods. However, means of sales promotion, frequency and time of task education, and competency required for door-to-door salespersons were not significantly related with sales of health functional foods. Customer relationship beliefs did not show significant association with sales of health functional foods either. In conclusion, certain factors were associated with sales of health functional foods by door-to-door saleswomen. These results provide an understanding for sales of door-to-door health functional foods and provide basic information for preparation of task education for health functional food saleswomen and marketing.

This study was intended to examine the influence of health consciousness on health/taste inferences, affect-based inferences, and perceived conflict between taste and health in food decision making. Seven hundred and fifty-four participants completed the survey. Structural equation modeling with a maximum likelihood method was used to test the relationships among constructs, following the two-step approach. The results of this study showed that more health-conscious consumers have a higher perceived healthfulness of food items but lower anticipated taste. In addition, this study also found consumers' cognitive responses influenced affective responses. Results suggested that when restaurants promote menu items as both healthy and tasty, consumers' positive hedonic emotions (such as pleasure) increased and negative self-conscious emotions (such as guilt) decreased, and consumers' efforts to balance health and taste were supported. At last, the implications both for academia and marketing were also established and discussed.

To understand the molecular mechanism involved in the survivability of cold-tolerant lactic acid bacteria was of great significance in food processing, since these bacteria play a key role in a variety of low-temperature fermented foods. In this study, the cold-stress response of probiotic Lactobacillus plantarum K25 isolated from Tibetan kefir grains was analyzed by iTRAQ proteomic method. By comparing differentially expressed (DE) protein profiles of the strain incubated at 10℃ and 37℃, 506 DE proteins were identified. The DE proteins involved in carbohydrate, amino acid and fatty acid biosynthesis and metabolism were significantly down-regulated, leading to a specific energy conservation survival mode. The DE proteins related to DNA repair, transcription and translation were up-regulated, implicating change of gene expression and more protein biosynthesis needed in response to cold stress. In addition, two-component system, quorum sensing and ABC (ATP-binding cassette) transporters also participated in cell cold-adaptation process. These findings provide novel insight into the cold-resistance mechanism in L. plantarum with potential application in low temperature fermented or preserved foods.
