This study aimed to investigate the acrylamide content in frozen food products after cooking. Twenty samples of bread (Group 1) and 30 samples of processed tuberous and corn vegetable products (Group 2) were selected. Acrylamide levels were quantified using liquid chromatography tandem-mass spectrometry (LC-MS/MS). The frozen food samples were heated using the air fryer cooking method according to the product packaging and were compared to ready-to-eat French fries (Group 3). The results showed that the acrylamide content was the highest in group 3, followed by that in group 2 and group 1. The acrylamide content of all the samples was found to be within the domestic recommended standard of 1 mg/kg. However, when the samples that exceeded EU benchmark level (0.5 mg/kg) were selected and cooked using the deep-fat frying method according to the product packaging, one of them showed the acrylamide content of 1.83 mg/kg, which exceeded the domestic recommended standard. The present study highlights the need for continued evaluation and management to reduce acrylamide contents in frozen foods, as increasing domestic exposure to acrylamide is concerning.
Purpose: This study investigated the dietary patterns associated with Korean food and the level of proper eating habits according to recognition of the Kimchi cooking method, and aimed to suggest the necessity of dietary education of traditional foods such as Kimchi. Methods: Based on the results of the national dietary survey conducted in 2014 by Ministry of Agriculture, Food and Rural Affairs of Korea, a total of 1200 subjects were classified into two groups, one that knew how to make Kimchi (53.8%) and another that did not (46.2%). Results: The group that knew how to make Kimchi (FG) showed significantly higher scores in knowledge of how to cook most types of Korean foods and traditional fermented foods than the other group (NG). Moreover, FG showed significantly higher scores in regularity in meals and a higher frequency of Korean foods such as rice, Kimchi, and grilled or stewed food, while it showed significantly lower scores in dietary risk factors than NG. In addition, FG showed significantly higher scores in dietary education interest and number of meals with family during the week than NG. Finally, FG had significantly higher scores in the degrees of practice of all eight items related to proper eating habits. Conclusion: Since recognition of Kimchi cooking has a great influence on maintenance of dietary life, dietary education to improve the cooking ability of traditional foods should be further strengthened.
The purpose of this study was to develop the NCS-based cooking practice education method by using the full learning model and to confirm its effect. The study design was a pre-post test of the non-equality control group. The subjects of this study included 28 students in the experimental group and 27 students in the control group. The experimental group participated in the NCS-based cooking practice training using the complete learning model, and the control group received only cooking practice training based on the full learning model. The data were collected during the second semester of 2016 and analyzed by SPSS WIN 23.0. The results of this study were as follows: First, homogeneity test showed that pre - homogeneity such as general characteristics, cooking ability, and knowledge of cooking theory were achieved (p>0.05). Second, the experimental group recognized that its cooking ability was high. With respect to the ability to cook food, the ability to cook, and the ability to prepare food ingredients (p<0.01), personal hygiene management, cooking hygiene management, and cooking safety management abilities were not significant. The mean value the experimental group was high. Third, the final theoretical knowledge score was not significant. The average score in the experimental group (69 points) was 5 points higher than that in the control group (64 points). This was about two times higher than the score of 37 points in the first stage preliminary survey. Finally, the final performance score was significant (p<0.05), and the score in the experimental group (89 points) was 5 points higher than that in the control group (84 points). Therefore, the NCS-based cooking education method is confirmed to be an effective method, especially for improvement of the practical ability, improvement of theoretical knowledge, and achievement of perfect learning standards.
본 연구는 지역별, 학교별, 계절별 고등학교 급식 식단의 미생물학적 안전성 관련 주요 영향 인자를 도출하고자 식단 데이터를 수집하고 요인을 분석하여 향후 안전관리 방향을 설정하기 위해 실시하였다. 급식식단 중 PHF(Potentially Hazardous Food) 해당여부, 사용빈도가 높은 엽경채류, 식단 조리방법에 관하여 빈도 분석과 다중대응분석(Multiple correspondence analysis, MCA)을 실시하였다. 중부지역과 남부지역의 각각 3개 고 교, 총 6개 고등학교의 3, 6, 9, 12월 제공된 총 1,945개 식단의 빈도분석 결과, PHF에 해당하는 식단은 데친 나 물류, 샐러드, 해조류, 닭튀김 등이 사용빈도가 높았다. 조리방법은 가열 여부에 따라 단순 가열, 단순 비가열, 혼합 여부에 따라 가열한 식재료와 가열한 식재료의 혼합, 비가열한 식재료와 비가열한 식재료의 혼합, 가열한 식재료와 비가열한 식재료의 혼합으로 구분하였는데, PHF 제품 내 단순 비가열과 가열한 식재료와 비가열한 식재료의 혼합과 같은 메뉴 유형도 33.1% 수준으로 나타났다. 사용빈도가 높은 엽경채류는 시금치, 부추, 상추, 양배추, 깻잎, 양상추, 치커리, 파, 브로콜리 순서로 나타났다. 전체 식단 중 사용빈도가 높은 엽경채류 14종 370개의 데 이터에 대한 MCA 결과 PHF에 해당하는 엽경채류에는 양상추, 청경채가, Non-PHF에 해당하는 엽경채류에는 브로콜리, 양배추, 치커리, 깻잎이 주로 사용되었다. 지역별로는 중부지역에서는 마늘쫑과 시금치가, 남부지역에는 미나리 사용빈도가 상대적으로 높았다. 향후 단체급식에서 농산물의 미생물학적 안전성을 높일수 있도록 생산단계에서 오염원 차단(GAP 인증), 저감 및 세척 공정 개발, 식재료별 조리방법에 따른 메뉴 데이터 베이스화, 미생물학적 안전성이 확보되는 조리방법을 활용한 식단 개발 및 검증이 필요하다.
This study examined the cooking method in "Eumsikdimibang", "Gyuhapchongseo" and "Jusiksiui" over time. The Korean cook book, "Jusiksiui", published in the late 1800s, was mainly investigated. The results showed that"Jusiksiui" contained more than 99 foods. In particular, there were 49 side dishes, including five types of porridge three types of noodles, and four types of dumplings. Most food recipes in "Jusiksieu" are the same as those in "Gyuhapchongseo". Results of comparison between "Gyuhapchongseo" (1809) and "Jusiksiui" (late 1800's), Korea's significant archives of Korean recipes, showed that approximately 50 recipes out of 99 recipes were the same as those indicated by "Yeolgujatang" and "Seunggiactang" as hospitality foods and "Gochujang", "Jeupjang", and "Jeupjihi" as traditional paste foods. This indicates that recipes in "Gyuhapchongseo" were transcribed into those in "Jusiksiui". Thus, "Jusiksiui" is the archive that includes recipes that have been passed down from generation to generation in a traditional family and transcribed archive of "Gyuhapchongseo", which was widely read by midwives in the late 1800's.
Although many studies have suggested that introducing the distance learning method, including Web-based learning, to a practice class is effective, studies applying the distance learning method to subjects who are practicing cooking are rare. The purpose of this study was to determine the perception of the distance learning method, the degree of computer use, and the use of distance learning by college students with cuisine-related majors to practice cooking. The results showed that most students used the distance learning method, and that the method was positively perceived, as it was a great aid in learning. Most of the cooking information was obtained through the internet, and the most effective learning media for practicing cooking was "e-learning" using a computer. The most effective learning method for those who were practicing cooking was a "face-to-face learning method", because face-to-face type of teaching and learning was most universally recognized. Most of the students surveyed responded that using the distance learning method was a positive experience, indicating that cyber lectures could be applied at more universities for subjects practicing cooking.

Ham, sausage and bacon were treated with common household processing techniques including refrigerated storage(0, 14, 28 days) and cooking(pan-frying, microwaving, boiling). Lipid oxidation was evaluated by measuring fatty acid composition, malonaldehyde(MA), TBA values and by measuring fluorescent products. Major fatty acid composition were oleic acid and followed respectively palmitic acid, stearic acid, linoleic acid, linolenic acid. There was no significant difference in fatty acid composition by cooking method but there was a tendency of being increased of unsaturated fatty acid during 28days storage. Ma, TBA and fluorescent products showed a tendency of being increased continually according to storage days rather than cooking method.
This study was designed evaluate the change of fat content according to cooking methods of ground beef. The results are summarized as follows. 1. The fat content of ground beef is the lowest in boiling cooking method. 2. The fatty-acids composition of ground beef is mainly palmitic and oleic acids. The fatty acids hardly change according to cooking methods. 3. P/S ratio is inclined to increase a bit after cooking than pre-cooking. From all the results obtained in this study it can be conclude that fat content is the lowest in boiling and microwaving cooking methods and fatty acid composition is mainly palmitic and oleic acids.
This study attempted to investigate the effect of housemaker's interest in dietary life on the knowledge of cooking principles and cooking methods, and on the daily meal management. Housemakers whose age ranged from 20 to 50 were surveyed in their residence. The results of this study were as follows. First, the level of interest in dietary life was positively related with ages, education and income levels. Moreover, housemaker who did not work or did not take care of relatives had higher level of interest in dietary life than those who did. Second, most housemakers bought foods and prepared a meal by themselves. The average time spent in preparing meals was 2 to 3 hours, and the number of side dishes cooked per day expect for the main dish was 5.46 percent of the total respondents ate out more than once a month for a 'family tie'. Third, there was no relation between the knowledge of cooking principle and the variables such as ages, education and income levels. Fourth, the level of the knowledge of cooking method about Korean traditional dishes was positively related with ages, education and income levels. In addition, housemakers who did not work or did not take care of relatives had less knowledge of Korean traditional dishes than those who did. Finally, the interest in dietary life was significantly correlated with the knowledge of cooking principle and cooking method of Korean traditional dishes.
