This study investigates the Gabo Jaedong Jemuljeongnyechaek, which is the recording of the darye executed over a period of a year in 1834 (34th year of reign by King Sunjo) in the latter part of the Joseon Dynasty, two years after the death of Princess Bokon, the 2nd daughter of King Sunjo. Accordingly, we examined the types of darye (tea ceremonies) and the characteristics of the composition of foods at ancestral rites of the royal families of Joseon. Moreover, we also analyzed the cooking methods and characteristics of food terminologies used in the darye. This includes 39 categories of food and ingredients used for tea ceremonies held for one year, on behalf of the deceased Princess Bokon in 1834. The darye for the monthly national holiday was held along with the darye on the 1st and the 15th day of every month. The darye for rising up and the birthday darye were held on May 12th and October 26th of the lunar calendar, being the anniversaries of the death and the birth of Princess Bokon, respectively. The birthday darye and the darye for New Year’s Day, Hansik (105thday after winter solstice), Dano (5th day of the 5th month of the lunar calendar), and Thanksgiving “Chuseok” were held in the palace and at the burial site of the Princess. During the darye for rising up in May and the Thanksgiving darye at the burial site in August, rituals offering meals to the deceased were also performed. The birthday darye at the burial site of Princess Bokon featured the most extensive range of foods offered, with a total of 33 dishes. Foods ranging 13~25 dishes were offered at the national holiday darye, while the darye on the 1st and the 15th of the month included 9~11 food preparations, making them more simplified with respect to the composition of foods offered at the ceremony, in comparison to the national holiday darye. The dishes were composed of ddeok, jogwa, silgea, hwachae, foods such as tang, jeok, jjim, hoe, and sikhae, and grain-based foods such as myeon, mandu, and juk. Foods offered at the burial site darye included 12~13 dishes comprising ban, tang, jochi, namul, chimchae, and jang. Meals offered at the darye had a composition similar to that of the daily royal table (sura). Darye recorded in the Jemuljeongnyechaek displayed characteristics of the seasonal foods of Korea. Jemuljeongnyechaek has detailed recordings of the materials, quantities, and prices of the materials required for preparations of the darye. It is quite certain that Jemuljeongnyechaek would have functioned as an essential reference in the process of purchasing and preparing the food materials for the darye, that were repeated quite frequently at the time.
This study investigated the Sachanbalgi, which record the royal feasts given by the royal family of the Joseon Dynasty of Korea. These records are contained within the Gungjung Balgi, which recorded the types and quantity of items used in royal court ceremonies. The Eumsikbalgi is the general name for the records of food found within this document. Using these Eumsikbalgi, and in particular the Sachanbalgi, this study investigated the food eaten and bestowed by the Joseon royal family. The Sachanbalgi describes four categories or occasions of feasts: royal birthdays, childbirth, royal weddings, and funerals. These records allow us to reconstruct who the attendees were and what the table settings and food were for instances not directly indicated in oral records, books, or other documents. The food at these Sachan (feasts) was diverse, being related to the specific event, and its contents varied based on the position of the person who was receiving the food. Usually, Bab (rice) was not found at a Sachanbalgi, and only on two occasions were meals with Bab observed. Specifically, it was served with Gwaktang (seaweed soup) at a childbirth feast. There were seven kinds of soups and stews that appeared in the Sachanbalgi: Gwaktang, Yeonpo (octopus soup), Japtang (mixed food stew), Chogyetang (chilled chicken soup), Sinseonro (royal hot pot), and Yukjang (beef and soybean paste). Nureumjeok (grilled brochette) and Saengchijeok (pheasant), and Ganjeonyueo (pan-fried cow liver fillet) and Saengseonjeonyueo (pan-fried fish fillet) were eaten. Yangjeonyueo, Haejeon, Tigakjeon (pan-fried kelp) and other dishes, known and unknown, were also recorded. Boiled meat slices appeared at high frequency (40 times) in the records; likewise, 22 kinds of rice cake and traditional sweets were frequently served at feasts. Five kinds of non-alcoholic beverages were provided. Seasonal fruits and nuts, such as fresh pear or fresh chestnut, are thought to have been served following the event. In addition, a variety of dishes including salted dry fish, boiled dish, kimchi, fruit preserved in honey, seasoned vegetables, mustard seeds, fish, porridge, fillet, steamed dishes, stir-fried dishes, vegetable wraps, fruit preserved in sugar, and jellied foods were given to guests, and noodles appear 16 times in the records. Courtiers were given Banhap, Tanghap, Myeonhap, wooden bowls, or lunchboxes. The types of food provided at royal events tracked the season. In addition, considering that for feasts food of the royal household was set out for receptions of guests, cooking instructions for the food in the lunchbox-type feasts followed the cooking instructions used in the royal kitchen at the given time. Previous studies on royal cuisine have dealt mostly with the Jineosang presented to the king, but in the Sachanbalgi, the food given by the royal family to its relatives, retainers, and attendants is recorded. The study of this document is important because it extends the knowledge regarding the food of the royal families of the Joseon Dynasty. The analysis of Sachanbalgi and the results of empirical research conducted to reconstruct the precise nature of that food will improve modern knowledge of royal cuisine.
This study aimed to provide insight into methods for activating management of traditional markets by understanding differences in merchant perception according to whether or not the merchant has participated in management activation education. Analysis of merchants’ levels of perception of market activation found that educated merchants had a higher perception of pre-post modernization satisfaction, promotion of traditional market revitalization projects, and post-support changes in sales. In a co-marketing context, educated merchants showed significant differences in onnuri gift certificates, bargain sales, festivals and events, and advertisement promotions. With regards to perception of management performances, educated merchants showed statistically significant higher responses for items such as satisfaction with the current vendor, increased sales, and increased customer awareness. The results in this study may be incorporated into the policy-making processes of the government or local governments in order to revitalize traditional markets, and merchant education for activation of management is deemed to be continuously necessary.
Indonesia has the largest economy in Southeast Asia and is one of the fastest growing economies of the world. This study was conducted to understand Indonesian food consumers, and to provide the marketing implications for food exporting companies in Korea. An online survey was conducted on 795 local consumers in Indonesia and the study analyzed their preference for Korean food and Korean culture. Then this study identified the relationship of these variables and consumers’ intention to purchase Korean food. The results of this study were as follows. First, Indonesian consumers had a strong preference for Ramyeon, noodles, snacks and kimchi among Korean foods. Second, the preference for Korean culture was high in a descending order of Korean dramas, cosmetics, songs and news. Third, both Korean food and Korean culture preferences showed significant differences depending on gender, age and the frequency of eating out. Lastly, analysis of the relationships among the variables showed that there is a positive relationship between Korean food preferences and Korean food purchase intentions. Further, the consumers’ Korean culture preference had a mediating effect within this relationship. The results of this study imply that marketers in Korea food companies need to consider the consumers’ preference for Korean food and Korean culture when they build proper strategies for exporting Korean foods to Indonesia.
This study was undertaken to examine the dietary adaptation in Korea, and utilization of university foodservice (UF), according to the nationality of foreign students. The survey was conducted from April to June in 2017, and included 604 subjects studying in a university in Busan. The questionnaire was designed to examine the adaptability to Korean food and the consumption of UF. The nationalities included students from China (63.4%), Vietnam (13.2%), Central Asia (8.9%), Southeast Asia (5.0%), and others (9.4%). Vietnamese and Southeast Asians showed higher adaptation to Korean food than Chinese or Central Asians. The degree of contribution of UF to diet was highest amongst the Chinese, followed by Vietnamese. The main reason for not consuming UF for the Chinese and Southeast Asians was ‘lack of menu variety’, and for Central Asians was ‘no menu that can be eaten, including due to religious reasons’. In order to improve UF, all groups asked for increased ‘variety of menu’, and Vietnamese and Southeast Asians also asked for ‘decrease in price’. In meat, fish, and vegetable menus, there were significant differences in the types and recipes of foods preferred, as per the nationality. These results indicate that different approaches by considering the national characteristics are required, to help international students adapt to Korean food, and to increase their consumption of UF.
The purpose of this study is to identify the impact of the performance-linked marketing of food companies on the satisfaction and willingness of the companies that purchase products. To achieve the purpose of this study, a survey was conducted on consumers who were using domestic coffee franchises. A total of 300 questionnaires were distributed, and only 291 were finally used for analysis, except for eight ones that were not sincere or valid. Performance-linked marketing consisted of promotional factors, support factors, production factors, and mouth-to-mouth factors, and the purchasing company’s satisfaction and willingness to purchase products consisted of a single factor. A linear regression analysis was performed using SPSS version 20.0 to verify the hypothesis. The research results show that (1) marketing linked to the performance by coffee shops has a significant impact on consumers’ willingness to purchase. (2) The marketing performance for coffee shops has a significant positive impact on the satisfaction of the purchasing company. (3) The consumer’s intention to purchase has a significant positive effect on the purchaser’s satisfaction. These findings confirm the importance of concert-linked marketing in the differentiated marketing by restaurant businesses.
The Ministry of Agriculture, Food and Rural Affairs has conducted the Dietary Education Projects at Childcare Centers since 2015. This study provides preliminary data for early childhood dietary education programs, by evaluating the outcomes of the projects. This survey enrolled 212 participants whose children had participated in the projects, and 142 non-participants. Comparing the perception of importance towards each educational program of the projects, dietary education program gained significantly higher importance than other subjects included, and was significantly higher in the participants than in non-participants. In the preference for food group survey for children, vegetable and seaweed preferences were higher among participants than non-participants, indicating that participation in the dietary education projects contribute towards increase in preferences for vegetables and seaweed, which children generally dislike. No significant differences were observed in children’s dietary habits between participant and non-participant groups, thereby suggesting that the education projects were insufficient for inducing dietary habit changes. In order to accomplish effective improvement of dietary habits, the education projects need further improvements to achieve systematic and long-term plans.
This study investigated the general information, unbalanced diet, and dietary habits of 86 children in Daegu. The research was undertaken to analyze the current state of diet and dietary habits of children, and to provide basic data for nutrition education. The results reveal that younger children have a more unbalanced diet. Children dislike side-dishes the most. Furthermore, due to the longer time taken to consume food, parents persuade children to eat quickly. Children were also determined to have a high intake of foods and drinks containing sugar; beverages containing sugar are consumed 1-2 times a week by 5-year-olds, and once daily by 6- and 7-year-olds. The results of this study can be applied to provide basic data for nutritional education, and assist in the development of dietary programs for young children.
This paper provides data for product development and improvement of grape varieties by analyzing the satisfactionimportance of the grape selection attributes from a consumer's perspective. A survey was conducted on consumers aged 19- 59 living in Seoul, Gyeonggi and Incheon on their fruit consumption level, preferences according to the grape quality characteristics, importance, and satisfaction with the grape selection attributes. Three hundred and eighty two valid samples were collected and analyzed statistically using SPSS 23. In the preference according to the grape quality characteristics, consumers tended to prefer a sweet taste, black color, and seedless grapes. Regarding the importance of the grape selection attributes according to the level of grape consumption, the high consumption group considers texture, size, shape, color, ease of removing seeds, country of origin, area of production, certification, and brand to be more important. In satisfaction, the high consumption group rated satisfaction highly in texture, odor, size, shape, color, ease of removing peelings, ease of removing seeds, price, country of origin, area of production, certification, and brand. An analysis of the IPA of the grape selection attributes showed that improvement of price and shape attributes will be prioritized, and the development and management of properties, such as seeds, peelings, certification, and brand will be required. These results can be used to help improve the grape varieties and develop products that meet the consumer needs, secure the competitiveness of grape farmers, and revitalize the local economy.
This study was undertaken to examine the quality characteristics of glutinous barley flour (GBF) Yakgwa produced by air frying. To achieve this, the pH of the dough as well as expansion ratio, color, texture, and sensory evaluation of Yakgwa were measured. The pH of the Yakgwa dough significantly decreases with increasing amount of GBF, over the range 5.35-5.45. Lightness (L), redness (a), and yellowness (b) also decrease with increasing amount of GBF. Furthermore, significant decrease was observed in the hardness, proportionate to the ratio of GBF added (p<0.001). Generic descriptive sensory evaluation results reveal that samples with high ratio of GBF show increased grain aroma, burnt aroma, grain flavor, nutty flavor, astringency, chalky taste, and hardness. The acceptance test determined the GBF-20 sample group to be high in flavor and texture (p<0.05). Therefore, it would be appropriate to apply to 20% GBF for alternative and the addition of GBF would be considered to have positive effects on the quality characteristics of Yakgwa using air fryer.
This study assessed the quality characteristics of cookies made with different amounts (0, 5, 10, 15%) of black carrot powder. The density and pH value of cookie dough were constant for all groups. Compared to the control group, the moisture content was higher in groups containing the black carrot powder. Increasing the amount of black carrot powder resulted in decreased L-value but increased a-value. Furthermore, the hardness of cookies increased with increasing amounts of black carrot powder. The consumer acceptance test revealed that up to 15% black carrot powder addition was desirable. Total phenol content of the control group was 24.0 mg GAE/100 g, while black carrot powder groups ranged from 45.5 to 103.5 mg GAE/100 g. The DPPH radical scavenging activity was also augmented with increasing volumes of black carrot powder. Taken together, we recommend that cookies with 15% black carrot powder are desirable in terms of overall acceptability and antioxidant activity.
To investigate Oiji (traditional Korean cucumber pickles) with reduced sodium content based on the use of saline foods as a salt substitute, Oiji was prepared using glasswort powder (Salicornia herbacea L.), and its physicochemical properties and sensory evaluation were examined. The moisture content of Oiji was shown to be higher in those to which glasswort powder had been added compared to the control without addition of glasswort powder, and Oiji with 40% glasswort powder substitute showed the highest pH and lowest acidity, resulting in slow progression of fermentation. The salinity of Oiji among those containing glasswort powder substitute was significantly higher with increasing level of glasswort powder. The sodium content of Oiji was significantly reduced as addition of glasswort powder increased. The L value of Oiji decreased with increased addition of glasswort powder, whereas the a value was highest in the control. The hardness of Oiji was higher in the control than in Oiji containing glasswort powder. Taste acceptance was highest for Oiji with 20% glasswort powder substitute, whereas acceptance of appearance was higher for Oiji with 10% glasswort powder substitute. Flavor and texture acceptance was higher for the control. In the attribute difference test, significant differences were found in brownness, off-flavor, salty taste, and sourness. Based on the findings, 10-20% substitution of salt with glasswort powder did not significantly lower overall acceptance compared to the control while salinity of Oiji was maintained. Therefore, the potential production of low-sodium Oiji has been verified.
This study examined the quality characteristics of jelly prepared with green grape juice (GJ). The pH, oBrix value, color, texture, and sensory evaluation of the jelly were measured. The pH of the jelly significantly decreased with increasing amount of GJ over the range of 3.25-5.27. The oBrix value of the jelly showed a significantly higher result as the amount of GJ increased (p<0.001). Lightness (L) and redness (a) decreased with increasing amount of GJ, and yellowness (b) increased. In the texture measurement, the GJ-100 sample group with a high substitute rate of GJ showed high hardness, gumminess, and chewiness (p<0.001). The results of principal component analysis (PCA) showed that the sample groups with high GJ content were classified as having relatively strong yellowness, sweet aroma, metallic aroma, grassy aroma, sweetness, sourness, green grape skin taste, and astringency. In the acceptance test, the GJ-50 sample group was evaluated to be high in flavor (p<0.001) and overall acceptance (p<0.01). However, sample groups consisting of 50% or more GJ were evaluated to be significantly strong in terms of astringency. Therefore, further study needs to be conducted about improving astringency in the future.
The purpose of this study was to optimize the mandarin dry chip manufacturing using a response surface methodology. The experiment was designed based on a CCD (Central Composite Design), and the independent variables were the drying temperature (X1, 50-90oC), drying time (X2, 12-36 hours), and microwave pretreat time (X3, 0-4 minutes). The results of appearance (Y5), color (Y6), taste (Y8) and overall acceptance (Y10) were fitted to the response surface methodology model (R2=0.86, 0.88, 0.89, and 0.84, respectively). Increasing the drying temperature and microwave treatment time were negatively evaluated for consumer acceptance. On the other hand, a high value of consumer acceptance was evaluated when the drying time was more than 24 hr. Therefore, the optimal conditions of X1, X2, and X3 were 52.989oC, 24 hr, and 1 min, respectively. Under these optimal conditions, the predicted values of Y5, Y6, Y8, and Y10 were 5.066, 5.338, 5.063, and 5.339, respectively.
Skin plays important roles in protecting the internal organs from the chemical-biological risk factors and ultraviolet light. Exposure to the chemical and biological stimuli has a detrimental effect on skin's structure and physiological regulation. Therefore, much attention has been paid to natural products that show biological activities such as anti-oxidation, anti-aging and anti-bacterial activities. In this study, we investigated the skin-related biological activities of Oenothera lamarckiana aerial part extract. The extract contained 229.35 mg TAE (tannic acid equivalents)/g total polyphenolic compounds and the extract showed relative high antioxidant activity (SC50 value: 8.52 μg/mL). The IC50 value against tyrosinase and elastase were 307.94 and 181.51 μg/mL, respectively. This suggested that O. lamarckiana can be applied to whiten skin and slow the aging of skin. O. lamarckiana extract showed a growth inhibitory effect on Staphylococcu epidermidis (minimum inhibitory concentration: 250 μg/mL). Interestingly, O. lamarckiana extract showed no inhibitory effect on Pseudomonas aeruginosa on the paper disc assay. Yet the extract inhibited the growth of Pseudomonas aeruginosa on the broth dilution assay in a dose-dependent manners. Taken together, O. lamarckiana could have good potential for development as an additive in the cosmetic industry.
