Pork is a popular meat consumed in Korea. However, the consumption pattern has typically focused on preferred parts, like pork belly, which is usually broiled. This consumption pattern has increased both stocks of low fat parts and medical costs, and has thereby disturbed pork industry growth and the national health welfare. Changing the consumption patterns of preferred parts and encouraging consumption of low fat parts will improve consumers’ quality of life and also increase their benefits. Thus, this study estimated WTP (Willingness To Pay) for health funds among consumers who eat pork meat, considering the health benefits gained by consuming low fat parts and changes in preferred part consumption. The results of this study show that WTP is higher when consumers have a smaller family and a higher income; these consumers plan to increase intake of pork meat in the future and think that the promotion of low fat pork meat consumption is more important. The WTP for health funds is estimated to be 49won to 287won through Logit Model. The health benefits of low fat consumption were estimated to be 92 billion won to 539 billion won per year. Therefore, reforming low fat pork consumption not only changes the traditional consumption pattern focused on preferred parts but also leads to a variety of benefits for consumers, including health benefits.
This study will introduce the foods recorded in Gyemiseo and disclose the substantive characteristics of traditional Korean food in the early stage of the Joseon Dynasty. Gyemiseo is a cook book manuscript written in the Chinese language that was rebound into book format at the end of the Joseon Dynasty in 1911, some 358 years after it was originally written in the 163rd year of the Joseon Dynasty (1554) While the majority of cook books begin with recipes for various types of wines and liquor followed by those for fermented sauces, fermented vegetables (such as kimchi), vinegars and storage methods, etc., Gyemiseo begins with recipes for fermented sauces, followed by recipes for various kimchis, how to make vinegars, main meals, side dishes, rice cakes and confectionaries, with recipes for wines and liquor introduced last. Therefore, it can be assumed that the methods of brewing wines and liquors were additionally recorded for bookbinding. There are a total of 128 recipes recorded in Gyemiseo, including 13 for fermented sauces, 14 for kimchi, 11 for the main meal, 26 for side dishes, three storage methods, four for rice cakes and confectionaries, and 44 for wines and liquors. It is believed that contents of Gyemiseo will provide a foundation on which to pursue researches on the process of transition of cooking methods of traditional cuisines of Korea during the Joseon Dynasty.
This study analyzed the Gichuk years JagyeongjeonJeongilJinchan Misu. The banquet, Misu is offered to the king by the crown prince, crown princess, and vassal, according to procedure. JagyeongjeonJeongil Misu are offered as 49 dishes spanning seven courses, so seven dishes in each misu are offered. Various types of food, such as Gawjeong, fruit, soups and side dishes, are placed. Misu involves only the king, crown prince, and crown princess in the banquet. The number of misu dishes are different for the King and prince. The table used is called the Joochil Sowonban and the tableware used is brassware and pottery. Sangwha used Peonies, Chinese rose, Red peach blossom-samjihwa, and Red peach blossombyulgeonhwa in each misu.
This study was conducted to determine the mixing conditions for Hibiscus syriacus L. chocolate depending on different addition ratios of Hibiscus syriacus L. and examine functionality in order to use Hibiscus syriacus L., which has excellent functionality and symbolizes Korea. To accomplish this, Hibiscus syriacus L. chocolate was manufactured by adding 0%, 2.5, 5, 7.5, and 10% of Hibiscus syriacus L. powder from the ‘Samchulli’ (Hibiscus syriacus ‘Samchulli’, which has reddish pink flower with red eye spot: SKK 14-2-72) variety to a coverture of white chocolate after which the antioxidant activity and quality characteristics were analyzed. As the amount of Hibiscus syriacus L. powder added to the chocolate increased, the chocolate color became darker, the pH decreased, and the sugar content and hardness increased. As a result of the sensory evaluation, the degree of preference increased as the amount of added Hibiscus syriacus L. powder increased to 7.5%. The degree of preference for color and flavor was the highest in the 5% added group, but the overall preference was 7.5% added chocolate. These findings demonstrate that adding Hibiscus syriacus L. powder to chocolate can increase chocolate functionality and preference and that there is a high possibility of Hibiscus syriacus L. chocolate development.
Germinated brown rice (GBR, Orysa sartiva L.) has been reported to have anti-obesity and anti-inflammatory effects. However, the mechanisms underlying these effects in adipocytes are not fully understood. Therefore, this study was conducted to explore the anti-inflammatory mechanisms of GBR on lipopolysaccharide (LPS)-stimulated 3T3-L1 adipocytes. 3T3-L1 adipocytes were pretreated with GBR extracts (0-20 mg/mL) 1 h before LPS stimulation. The mRNA expression of adipokines and Toll-like receptor 4 (TLR4) were measured by RT-PCR. The protein expressions of TLR4- related molecules were detected by western blotting and nuclear factor-κB (NF-κB) activation was measured. Our results showed that GBR extract dose-dependently inhibited mRNA expression of LPS-induced tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and monocyte chemoattractant protein-1 (MCP-1). GBR extract was found to inhibit LPS-induced mRNA expression of TLR4 and protein expression of both myeloid differentiation factor 88 (MyD88) and TNF receptorassociated factor 6 (TRAF6). Furthermore, GBR extract significantly inhibited extracellular receptor-activated kinase (ERK) phosphorylation and NF-κB activation. These results suggest that GBR extract has the anti-inflammatory effects on LPSinduced inflammation via inhibition of TLR4 signaling, includingthe ERK and NF-κB signaling pathways, in adipocytes.
This study examined how the consumers’ perception of GM food affects their purchasing behavior. In addition, this study investigated how the amount of knowledge a consumer has regarding GM food affects their perception of this type of food. The quantitative research method was used to collect data. The data from a self-administered survey, which was conducted in South Korea, was analyzed using descriptive analysis, ANOVA, factor analysis, and multiple regression analysis methods. The results of the survey indicate that most respondents may have unknowingly purchased GM food. Further, the respondents reported that they likely had known about or had heard of GM food. In addition, the survey indicated that the amount of knowledge possessed by the respondents regarding GM food greatly affected their perceptions of this type of food. These findings will contribute to the current GM food market by providing the food market with additional information relating to the consumers’ perceptions of GM food.
With increasing interest in the health and safety of food served in restaurants, more emphasis is being placed on the importance of health and food. As a result, Yaksun cuisine with new added effects and image is becoming more popular as a way to improve people’s health. This study analyzed the effects of selection attributes relating to Yaksun cuisine on customer satisfaction and intention to maintain relationship in order to understand various needs of consumers as they relate to health food. The results showed that, among selection attributes of Yaksun cuisine, price, safety, and health were found to have significant effects on customer satisfaction; however, the effect of quality on satisfaction was not verified. Moreover, while the effect of safety and health of Yaksun cuisine on the intention to maintain relationship was found to be significant, the effects of quality and price on the intention to maintain relationship were not verified. These findings suggest that consumers believe Yaksun cuisine is more beneficial for health than general food and trust the origin label, hygiene, and safety of ingredients in Yaksun cuisine. Therefore, the results of this study suggests providing opportunities for consumers to experience diverse tastes in Yaksun cuisine and that development and promotion of different recipes using Yaksun ingredients will help reinforce competitiveness of Yaksun cuisine in the market and increase sales.
Although milk, which is a representative western food, has a more than 100-year history in Korea, the preference is controversial. This study examined the milk history of Choseon in 1884~1938. This period was divided into 4 periods regarding the westerner’s records and advertisements. Westerners who visited Choseon in 1884~1895 (1st period) recorded the eating habits of Choseon,i.e., no milk consumed, even in insufficient food situation. Among the westerners, medical missionaries began to show or/and recommend condensed milk for sick children. In 1896~1909 (2nd period) newspapers, general shops in Hanseong for westerners showed advertisements of dairy products. In the 1900s, condensed and raw milk were advertised through newspapers. Domestic ranching systems to produce raw milk were established at that time mainly by Japanese. In the 1910s (3rd period), raw milk and condensed milk were advertised in newspapers. Since the mid-1920s (4th period), dairy products were bisected into condensed and powdered (dried) milk. Moreover, many Japanese manufacturers appeared in the advertisement in the 1920s. These results suggest that milk has been recognized as a symbol of an enlightenment food in Korea since the late 1900s, but the old negative wisdom, unfamiliar taste, and high price of milk at that time limited its appeal.
This study evaluated the quality characteristics of wet noodles added with sword bean powder(0, 5, 10, 15%) to determine the most preferred noodle recipe for consumer’s desire. The proximate composition of the sword bean powder was as follows: Moisture contents were 13.4±0.08%, protein 30.2±0.12%, fat 0.3±0.09%, protein 1.0±0.11% and carbohydrates 55.1±0.12%, respectively. Total amino acid content of sword bean powder was measured 23,054.266 mg/ 100 g, especially in the order of histidine, glutamic acid and aspartic acid. The flavonoid content of sword bean powder was 17.9750 mg%. Water-binding capacity increased as the level of sword bean powder increased. When viscosity of wheat flours containing sword bean powder was measured by amylograph, the gelatinization point increased significantly as the level of sword bean powder increased, but peak viscosity decreased. As the level of sword bean powder increased, L value decreased, whereas a and b values increased. Weight, water absorption and volume of cooked noodles prepared with wheat flours containing sword bean powder decreased, whereas turbidity of soup increased. For textural properties, addition of sword bean powder increased hardness, springiness, chewiness of cooked noodles, whereas adhesiveness decreased. According to sensory evaluation such as appearance, color, flavor, taste, texture, overall preference, it was revealed noodles with 10% sword bean powder was the most preferred. According to the results, the addition of sword bean powder positively affects the overall sensory evaluation of wet noodle, and 10% is the optimal level for addition.
This study investigated Balgis (the record of the court)in the Joseon Dynasty pertaining to table settings for Sangsik (the meals for the dead). Sangsik are the records of daily meals for kings and key figures. In this study,14 pieces of Sangsikbalgi from 1890 to 1920, including two pieces from an unspecified period, were investigated to determine the composition and types of daily meals in the court. Meals consisted of a minimum of 10 dishes to a maximum 21 dishes, which basically included rice and soup. ‘Jochi’ was the term to refer to jjigae (stew) in the court. In Sangsikbalgi Bokgi, Gamjang, Jochi, Jjim, Suk, and Cho were all considered Jochi, which were recorded before Jeok or Jeon, where the side dishes were listed after rice and soup. This corresponded with the record of the royal tables in Wonhaeng-Ulmyo-Jeongri-Uigwe (圓行乙卯整理儀 軌), in which Jochi included Jabjangjeon, Bokgi, Jabjang, and Cho. Whitebait and fruit, which are used as ingredients for Tang (soup) and Jeon, showed seasonal characteristics however, no other observed dishes showed seasonal variability. Additionally, beef and internal organs of animals were frequently used,regardless of seasons. When dishes in Sangsik were classified into basic dishes and additional cheop dishes (side dishes) based on Siuijeonseo (are recipe book of unknown authorship written in the late Joseon Dynasty), from five to nine Cheop dishes were set on the table, with seven being most common. Further comprehensive study needs to be conducted through undisclosed documents and private collections. Moreover, additional study of Judarye (anestral rites during the day for the royal) and cooking methods that were not investigated in detail in this study are needed.
This study was conducted to investigate the effects of health lifestyle on high protein snack selection attributes and purchase behaviors among individuals aged 20-30 with high protein snack intake. In addition, the relationship between perception, attitude, satisfaction and recommendation of high protein snacks was invested. Finally, this study aims to provide basic information for marketing high-protein snacks and customized high protein snacks. Analysis of the selection attributes most important for healthy lifestyle, revealed significant differences among all groups excluding the external seeking group (p<0.001). The free living group regarded trust as one of the most important attributes of high protein snack selection, and both the tempered control group and the low-interest group found sensation and price factor to be important. Therefore, when developing high-protein snacks, it is important to determine which attributes of the snack will be highlighted by segmenting the consumer into health lifestyles. Focusing on what ingredients are used to develop high-protein snacks and nutritional ingredients is also important when targeting a free lifestyle group as the main customer. In addition, developing snacks that do not offer depending on the protein content is important when targeting a temperate management group or a low-interest group.
