  • More than 500 different compounds have been identified in the cooking process of frying oil as a result of chemical reactions such as oxidation, polymerization, hydrolysis and pyrolysis, 3-MCPDe(3-Monochloropropane -1,2-diol ester) and GE(glycidyl ester) are also included in these compounds. When MCPDe and GE derivatives are absorbed into the body, they are converted into free forms by lipase enzymes, which turn into 3-MCPD and glycidol(2,3-epoxy-1-propanol), respectively. These exhibit genotoxic and carcinogenic effects. As the toxicity of 3-MCPDe and GE is known worldwide, the health risk is being researched. However, regulations have not been established in countries other than the European Union(EU). Several studies for the analysis of 3-MCPDe and GE are being conducted, and direct methods and indirect methods are applied. As a result of analyzing 3-MCPDe and GE contained in commercially available foods by various analysis methods, the content of 3-MCPDe in baby food/infant formula was ND~600 ㎍/mL and GE was ND~750 ㎍/mL. and purified vegetable oils and fats showed <250-8,430 ㎍/mL and 1,880-9,530 ㎍/mL. Thus, 3-MCPDe and GE were detected in various food types, several studies for the reduction of 3-MCPDe and GE are being conducted around the world.

  • In this survey, we investigated the way of thinking about meal management of housewives including the sincerity to meal preparation, the eating practices and cronic degenerative diseases related dietary behaviors, and studied the effects of above factors on the real food intakes. We also investigated the trends of health-foods and nutrient supplements usage. The results obtained from 506 housewives in Seoul were summarized as follows. Although our subjects prepared their meals habitually without special concern, they did not prefer the use of convenient foods. The food prefrence of housewivess who had more child and refered higher life status was similar with other family members. The dietary attitudes were good in large family, the higher income and the more child group. The highly educated group skipped breakfast more frequently. The mealmanagers with better education career and good living status considered for the restriction of salty foods, sweet foods, animal fats and pungent foods, and for the nutritionally balanced diet. The high income group showed great concerns about weight gain at meal times. The nutritional qualities expressed by the frequency of food group intakes were high in the better educated and living status groups, and their eating frequencies of animal protein foods and calcium sources were significantly high. Mealmanagers who had no job intaked vegetable oils through frying foods frequently. The use of health-foods and nutrient supplements was influenced by age, educational and economic level and self-estimated living status, but the trends in prevalence of both were not consistent. Health-foods were prefered by the groups of high educational career, affluent income and advanced living status, and low educational career, low income and low living status groups favored the nutrient supplements. The restrictive intake of animal fat and the use of health-food were positively correlated, which seemed that the subjects used health-foods as supplements in compensation for nutritional unbalance caused by the avoidance of animal protein foods.

  • Acrolein is highly toxic and may be formed from carbohydrates, vegetable oils, animal fats and amino acids during heating of food. In the present study, we investigated adults' intake level of cooked meat using high temperature cooking method such as pan frying or grilling directly over an open flame and indirect fire using pan. The 925 adults (438 men and 487 women) participated in this nationwide survey. According to the result of frequency intake of cooked meat at high temperature, the most frequently consumed cooked meat at high temperature was fried chicken, followed by indirect cooking-samgeybsal and directly grilled fish and mackerel pike among twenty five kinds of cooked meats and foods, which were eaten more than three times per month. The woman consumed direct grilled fish and mackerel pike more than three times per month, while the man consumed samgeybsal, pork cutlet, and fried chicken once per week. The order of total intake amount of cooked meat per adult for a year is 10.3 kg of fried chicken (man 13.1 kg, woman 8.04 kg), 6.7 kg of samgeybsal (man 9.4 kg, woman 4.7 kg) and 5.1 kg of jeyukbockeum (man 7.0 kg, woman 3.6 kg). The results of present study suggest that adult must realize the risk of consuming cooked meat at high temperature and the need for education for proper dietary habit to prevent geriatric diseases.
