The purpose of this study is to analyze information about dietary information presented in the television broadcast media in order to determine the optimal communication method that will provide desirable information to the general public. To that end, stakeholders were recruited and trained before and during the study. Three airwaves broadcasters and four comprehensive programming channels were monitored for Three months. The results are as follows. In total 172 food and nutrition programs are reported on. As information from the monitored programs was investigated, results showed a frequency of 136 separate informative programs (79.1%) and 36 entertainment programs (20.9%). Second, the broadcasters included are KBS, MBC, SBS, while the channels are TV Chosun, JTBC, Channel A, and MBN. Third, 109 reports (63.3%) were about ingredients & cuisine, followed by 63 reports (36.7%) on health and diet. This research provides transitional knowledge regarding the correlation between dietary information and the media. Moreover, this research contributes to advocating public health by enhancing the quality from broadcast media about dietary information.
This study reviewed Korean food recipes and food culture included in English cookbooks issued in the United States from the 1930s to the early 1970s. In the 1930s cookbook, many types of soup were introduced to Korean food under the influence of the Tangban culture in the Joseon dynasty and a brief description of ‘Sinseollo’ culture. The 1940s cookbooks, introduced Korean table settings, food culture, and cooking methods depending on the use of chopsticks. In the 1950s cookbooks, Korean foods were selected to suit a Western table setting, and detailed explanations were included along with ‘cheopsu’ means the number of dishes served in Korean food. More diverse Korean food was introduced within its culture and origins in the 1960s cookbooks. The 1970s cookbooks explained, the characteristics of Korean culinary specialties that differentiated from oriental food. This study of Korean food and culture from Cookbooks issued in the United States from the 1930s to 1970s, where Eastern and Western multiculturalism coexist, can be used as baseline data to understand the identity of modern Korean food culture and the direction of the globalization of Korean food.
This study analyzed food poisoning articles in the Joseonwangjosillok to acquire historical evidence. The study method used case studies from the textual content of the Joseonwangjosillok. In all, there were fifteen cases of food poisoning in spring (60%), four cases in summer (16%), five cases in fall (20%), and 1 case during winter (4%). Most cases of food poisoning occurred during spring, followed by fall, then summer, and the least during winter. Foods that caused poisoning were as follows: twelve cases of seafood (48%), three cases of vegetables (12%), two cases of meat (8%), and eight cases of poisonous food (32%). Maximum cases pertained to seafood poisoning, which also spiked during spring. This could be attributed to the increased number of planktons as the sea temperature rose during spring. Due to the increased plankton, shellfish absorbed more toxins. The consumption of increasingly toxic shellfish resulted in more cases of food poisoning. The food poisoning frequency was the most severe during the 18th century, followed sequentially by the 15th, 16th, and 17th centuries, and was the least severe during the 19th century. Joseonwangjosillok showed that food poisoning cases happened most during social events where many guests or family members gathered to eat.
The purpose of this study was to investigate the preparation and cooking processes used to prepare Eungi in cookbooks published from the 1700s to the 1900s. ‘Eungi’ is a thin gruel made of starch powder. Fourteen historical cookbooks were included and investigated for the preparation of ingredients and processing methods. Fourteen types of eungi were identified. Arrowroot eui and kuseonwangdogo eui were found in 『Kyuhapchongseo』 written in the early 1800s, and many types of eungi (i.e. job’s tears eungi, arrowroot eungi, sorghum eungi, lotus root eungi) were mentioned in 『Kunhakhoedeung』, but unfortunately, ingredients and cooking methods were not included. ‘Eungi’ was made by boiling starch powder prepared using the ‘subi method’, that is, dried after grinding main ingredients such as job’s tears using a millstone followed by soaking and settling. Eungi boiled with water or omija water were seasoned with the sugar or honey, and salt. These eungis were used for stomach complaints and hangovers and to promote longevity.
This study was conducted to provide basic data for product development and marketing strategies for the Thai home meal replacement (HMR) market, to reflect the changing trends in household sizes in Thailand. The results of analyzing the characteristics and differences of HMR consumption behavior between single-person households and multi-person households in Thailand were as follows: It was found that single-person households use HMR to save money and for the convenience in cooking and preparation. In the preference by HMR type, multi-person households showed a higher preference for all types of products than single-person households. Thai consumers, regardless of their household size, mainly use department stores and large shopping malls to purchase HMR, and they most prefer to get information through Internet advertisements. The shelf life, quality, taste, hygiene, and freshness of HMR were the main considerations for their selection. Based on the results of this study, the Thai market requires the development of HMR products that are reasonable in terms of cost and preparation time. In addition, it is necessary to develop products that can satisfy consumer needs, such as nutritional enhancement and therapeutic foods, products that are organic, eco-friendly, cater to various menus, and address the premium segment.
The study was aimed to investigate the operational meal costs by kindergarten size in Seoul and to analyze recognition for optimal meal prices. A survey (31.6% recovery rate) was conducted on all kindergartens (779 kindergartens) in Seoul on April 2021 using descriptive analysis, t-test, and dispersion method. A price sensitivity measurement (psm) method was used to determine optimal meal prices. Result showed an average food cost for kindergartens of 2,647 won, an average labor cost of 605 won, an average operating cost of 146 won, and the total meal cost of 3,506 won. Total meal cost decreased with increasing kindergarten size (p<0.001). On the other hand, kindergartens with more students decreased the ratio of food cost to total meal cost, and operating cost and labor costs (p<0.001) increased. The optimal price of kindergarten operators' meal cost (OPP) was KRW 3,673. Furthermore, the analysis showed the sensitivity of operators' meal costs to kindergarten size was insignificant.
This study compared the physicochemical and gelatinization properties of naked barley, tetrastichum barley, and waxy barley. Compared to tetrastichum barley and waxy barley, naked barley had shorter and rounder grains with a 1.43 length/ width ratio. Tetrastichum barley had lower crude protein, crude lipid, and crude ash content and higher amylose content compared to naked barley and waxy barley. The L, a, b color values of waxy barley were significantly higher than those of naked barley and tetrastichum barley. The water absorption index (WAI) and the water soluble index (WSI) were highest in waxy barley. The X-ray diffraction pattern was type A in all samples, and the peak intensity was highest in waxy barley. The maximum viscosity, cooling viscosity, breakdown, and setback of amylogram properties were the highest in tetrastichum barley. The thermal properties through the differential scanning calorimeter showed that the waxy barley had higher values of the onset, peak, conclusion temperature and enthalpy (?H). In conclusion, the variety of barley influenced the physicochemical and gelatinization properties, which could be important factors in the manufacture of processed foods. These results would thus useful inputs for the manufacturing of these foods using barley.
The purpose of this study was to investigate the possibility of using air potato (Dioscorea bulbifera) powder to make sponge cakes. The sponge cake batter was made by adding 0, 10, 20, 30, and 40% of air potato powder, and the resultant anti-oxidative properties and quality characteristics were analyzed. The study showed that the height, batter yield, and loss rate of sponge cakes decreased as increasing amounts of air potato powder were added, but the weight, viscosity, moisture content, and specific gravity increased. An evaluation of the color showed that the L and b values were highest in the control group but the a value was highest in the 40% group. There was no significant difference between samples in terms of cohesiveness, although the study showed a significant increase in the hardness, chewiness, and gumminess as the quantity of air potato powder in the sponge cakes increased. The total polyphenol content and DPPH radical scavenging activity increased noticeably as more air potato powder was added to the sponge cakes. The results thus showed that the study groups with the addition of air potato powder showed higher antioxidant activity than the control group.
Galactosemia is a rare, hereditary metabolic disorder caused by the accumulation of galactose and its metabolites in the body due to a lack of enzymes that convert galactose to glucose. This study aimed to investigate the dietary behaviors and nutritional statuses of patients with galactosemia and to provide basic information on the development of nutrition education programs to improve quality of dietary life. A survey was conducted on 13 parents of (<11 years of age) children with galactosemia and 26 parents of (<11 years of age) children without galactosemia. Mean body mass index was greater for school-age children with galactosemia (18.77 kg/m2) than for corresponding normal children (16.55 kg/m2). Underweight and obesity rates of children with galactosemia were greater than those of children without galactosemia. In addition, children with galactosemia had a higher food neophobia rate and thus consumed less food. Normal children exhibited a greater range of food preferences than those with galactosemia, especially for milk and dairy products (p= .001) and fats and sweets (p= .04). Reliable food databases and appropriate dietary recommendations are required to ensure the proper growth of children with galactosemia.
This study was performed to develop a Kdiet-index based on the definitions and characteristics of traditional Korean food. The Korean Food Pattern Index (Kdiet-index) for diseases was applied using dietary data from the 2017 National Health and Nutrition Examination Survey (KNHANES) and the association between Kdiet-index and metabolic disease was confirmed. The study subjects were 1,971 Korean adults aged >40, and the components were classified according to 14 criteria used to establish the Kdiet-index. Main ingredients up to the top 3 were designated using dish names, ingredients, and contents using KNHANES dietary data. Kdiet-index was classified using scores of ≤3 points, 4-7 points, and ≥8 points and total Kdietindex were calculated by summing dietary scores. Correlations between Kdiet-index and obesity, hypertension, hyperlipidemia, and diabetes were analyzed. The odds ratio (OR) and 95% confidence interval (CI) for obesity were 0.531, 0.385~0.732 and for elevated cholesterol (≥240 mg/dL) indices were 0.471, 0.282~0.788, respectively, which showed a significant decreased in the risk for each disease for Kdiet-index of ≥8 points. This study confirms that metabolically related clinical results improved significantly as Kdiet-index increased and that higher Korean food pattern indices are associated with lower risks of metabolic disease
