The purpose of this report is to present a list of Korean foods containing histamine, that is known to cause food allergy and chronic urticaria. For the measurement of histamine in foods, the application of spectrofluorimeter is used. Among the food groups, sea foods (mackerel, pacific saury, spanish mackerel, anchovy, hair, tail, tuna) contain most high amount of histamine, and the contents of see weeds (sea mustard, laverare) are also high. Milk and milk products (mozzarella cheese, yogurt) contain more histamine than animal meats. Plant foods like cereals, vegetables or fruits contain much less histamine than other food groups, except spinach. The contents of dried sesame, sesame oil, and mugicha, green tea, ginseng tea, mayonnaise, tomato ketchup are relatively high. This paper will be used as a fundamental guideline in planning dietary management of allergy and for the operational plans for the future nutrition education intervention. Because the foods rich in histamine may cause allergy-like syptoms, it may be reqoiled to label the foods containing histamine.

Objectives: This study examined regional differences in the intake of dietary total fat and saturated fatty acid (SFA) and their food sources among Korean adults. We also investigated the associations of SFA intake with metabolic diseases by region. Methods: This study included 13,926 adults (≥ 19y) who participated in the 2016 ~ 2019 Korea National Health and Nutrition Examination Surveys. The regions were divided into urban and rural areas according to the administrative districts where the participants lived. Using dietary data obtained from a 24-h recall, intake of total fat and SFA and their food sources were assessed by region. Metabolic diseases included obesity, abdominal obesity, and elevated total cholesterol and their association with SFA intake by region were examined using multiple logistic regression. Results: Of the participants, 19.6% lived in rural areas. In urban areas, the total fat and SFA intakes were higher than in rural areas: 21.2% of energy (%E) came from total fat and 6.9%E from SFA in urban areas, whereas 18.0%E came from total fat and 5.8%E from SFA in rural areas. The percentage of participants who exceeded the dietary reference intakes for total fat and SFA in urban areas was 16.5% and 41.9%, respectively, but 43.4% of participants in rural areas showed lower intake levels for total fat compared to the reference level. Young adults did not show regional differences in fat intake, and the percentage of subjects who exceeded the reference for SFA was high both in urban (58.5%) and rural (55.7%) areas. Among middle-aged and older adults, intake of fatty acids except for n-3 fatty acid was significantly higher in urban areas than in rural areas. About 69% of older adults in rural areas showed a lower intake of total fat compared to the reference level. The food sources for total fat and SFA were meat, soybean oil, eggs, and milk in both areas. The intake of fat from eggs, milk, mayonnaise, and bread was higher in urban areas, but the intake of fat from white rice and coffee mix was higher in rural areas. The SFA intake was positively associated with elevated serum total cholesterol in urban areas (4th quartile vs. 1st quartile, OR: 1.22, 95% CI: 1.06-1.40, P for trend: 0.043), but not in rural areas. Conclusions: Regional differences in total fat and SFA intakes and their food sources were observed among Korean adults. Our findings may help plan nutritional strategies to ameliorate regional health disparities.

In this study, the quality characteristics of salad dressing prepared with mulberry, Schisandra chinensis, and Discorea powder were evaluated. Salad dressing was prepared with salad base (plain yogurt : mayonnaise : fresh cream = 8:1:1), mulberry, Schisandra chinensis for acidity, and Discorea powder for viscosity (4:4:6:1 or 4:4:6:3). Discorea powder was added at levels of 0, 7, and 18% to the salad dressing. As the concentration of Discorea powder increased, the pH level increased, and acidity decreased. Hunter's color L (lightness) value of salad dressing decreased as the amount of Discorea powder increased. Viscosity increased according to the amount of Discorea powder. Moreover, total phenolic content increased according to the amount of Discorea powder. Further, DPPH antioxidant and hydroxyl radical activity of mulberry salad dressing increased as the amount of Discorea powder increased. Sensory preference test results showed that the salad dressing added with Discorea powder had higher scores for color, flavor, taste, and texture than the control. Regarding overall preference, salad dressing containing 7% Discorea powder had the highest scores among the treatments. From these results, salad dressing containing mulberry, Schisandra chinensis for acidity, and Discorea powder for viscosity could be a functional salad dressing with high antioxidant activity.

Six kinds of spirulina added dressing $(0\~1.09\%)$ were prepared and their rheological, physical and sensory characteristics were evaluated The hardness and adhesiveness of spirulina-added salad dressing were increased with the added amounts of spirulina. Viscosity of spirulina-added salad dressing was not significantly different up to $0.28\%$ whereas that of dressing added more than $0.55\%$ spirulina significantly increased, compared with that without spirulina. Emulsion stability of all of spirulina-added salad dressings was $40\%$ Antioxidant activities of spirulina-added salad dressing increased with spirulina increased: $IC_{50}$ values of DPPH radical scavenging activity and lipid peroxidation inhibition activity of $0.28\%$ added-dressing were 104.98 mg/mL and $6.71{\mu}g/mL$ of TBARS, respectively, which were higher than those of mayonnaise. The fat globule size of $0.28\%$ spirulina-added salad dressing was distributed within $0.5\~4.0{\mu}m$, of which $85.6\%$ of total fat globules were consisted of the size of less than $1.5\{\mu}m$. Total microbial number of salad dressing was 6.2log(CFU/mL), but E coli was not detected Sensory preference test of spirulina-added salad dressing showed that scores of appearance, flavor, viscosity and over-all preference for $0.28\%$ added-dressing were the highest with 7.83, 7.50, 5.33 and 7.97, respectively. Based on these results, spirulina-added salad dressing might have heath promoting effect showing antioxidant activity, and the most appropriate concentration of spirulina for salad dressing was $0.28\%$.

This research was conducted on Seoul region elementary, middle, and high school nutritionists to analyze execution conditions of HACCP control standards, focusing on PHF and CCP 3~CCP 7, in order to determine more efficient methods for school meals' sanitation system settlement. All surveys were distributed and collected via email. A total of 305 survey papers were collected, and 300 school results were analyzed. The following percentage of nutritionists perceived the following foods as potentially hazardous foods(PHF): raw or cooked animal foods (94.7%), blossomed seed products (93.7%), packed pickled radish (36.7%), unopened mayonnaise (30.2%), and unopened snails & corn cans 54.8%. Exactly 51.2% of nutritionists believed that foods were properly supplied via CCP 3's food quality standard. Exactly 33.9% of nutritionists answered that they had never corrected the digital thermometer since there were no issues with the CCP 4's digital thermometer correction frequency level. As for CCP 5's chroline disinfection of green vegetables, 57.1% of nutritionists answered that vegetables were slightly softened while 36.2% said there were no changes at all. According to the nutritionists, the most difficult execution level of CCP levels (excluding CCP 3, CCP 4) was CCP 7 (37.1%), CCP 6 (16.4%), and CCP 2 (16.4%). For the above results, proper training/education must be enforced so that nutritionists can have a clear notion of the PHF. A solution must be developed enhancing the execution of CCP 4's digital thermometer correction frequency level. For CP 5's chroline disinfection of green vegetables, food characteristics must be considered to suggest an appropriate number and method of cleansing. Furthermore, cooking employees are needed that properly use and manage cooling & heating equipments to maintain heated foods above $57^{\circ}C$ under the CCP 7 standard.

The purpose of this study was to investigate the effect of food behavior on dietary food intake status and health condition based on research of food behavior and nutritional intake status of university students in the Chungnam area. The average age, height, and weight of the subject group were 22.1 years old, 174.2 cm, and 67.0 kg for the male students and 20.9 years old, 161.8 cm, and 53.4 kg for the female students, respectively. From the nutritional intake status data, the averaged daily energy intake of both groups, male and female, are lower than the dietary reference intake(KDRI), as 2,169.2 kcal and 1,846.2 kcal, males and females, respectively. The lipid intake ratio was higher than the dietary reference figure, and the carbohydrate intake ratio was determined to be in the proper range. Male students(54.6%) and female students(52.0%) of the entire subject group skipped a breakfast mainly due to insufficient time, and the time at which meals were consumed, was determined to be irregular generally. In a day, male and female students have a heavier dinner than lunch(p<0.05), respectively. Meat and fishes are preferred by the entire subject group, and the number of students, who do not eat carrot and mayonnaise(p<0.05), was determined to be the highest, of all foods surveyed. The averaged daily activity coefficient and the resting energy expenditure shows significant difference(p<0.001) between two groups; was 1.7 and 1.6 and the second was 1,404.3 kcal/day and 1,292.5 kcal/day for the male and female groups, respectively. As the number of attempting to reduce body weight(p<0.001), the amount smoking(p<0.001), or the frequency of drinking alcohol increases, BMI decreases. On the other hand, as body shape satisfaction increases, BMI increases also.

In this study, we examined the effects of dietary 1,3-diacylglycerol (DG) compared to conventional triacylglycerol (TG) oil on the postprandial response of total and chylomicron TG, glucose, insulin, and free fatty acid (FFA). This study was conducted using a cross-over design. Ninety subjects participated in the high-fat meal tolerance test where they were randomly assigned to consume two experimental sandwiches containing mayonnaise with TG or DG oil with a seven-day interval. Blood samples were collected before ingestion and at 2, 3, 4 and 6 hr time point after ingestion and analyzed for total and chylomicron TG, glucose, insulin, FFA and phospholipid fatty acid composition. Both TG and DG ingestion had similar effects on postprandial TG response, but a different response from chylomicron TG. Compared with the TG group, TG levels were significantly lower only at 6 hr time point in the DG group. On the other hand, chylomicron TG rose steeply at 2 hr time point and decreased faster in this group. Also, the adjusted value to fasting levels was the same as the unadjusted level. Fasting levels and net differences in insulin were significantly lower at 3 hr time point where chylomicron TG levels were significantly lower in the DG group. But those of glucose and FFA in the TG and DG groups did not differ significantly. Fasting and postprandial levels of fatty acid composition in serum phospholipids in the two groups did not differ significantly. In conclusion, this study indicated that one could reduce the magnitude of postprandial lipemia without influencing glucose metabolism by consumning DG oil as a substitute for TG oil. Based on the correlation of coronary artery disease and postprandial lipemia, dietary DG ingestion might have a beneficial effect in treating such a disease. Further studies are required to clarify the long-tenn effects of dietary DG on blood lipid levels in humans.
