This study was conducted to investigate the fermentation characteristics and anti-obesity effects of Cheonnyuncho (Oputia Humifusa) fruit fermented with Lactobacillus plantarum SRCM 100320 (FC). The pH gradually decreased from 4.77 to 3.63 at 72 hours during fermentation. Counts of lactic acid bacteria, total polyphenol and flavonoid contents and DPPH scavenging activity were the highest at 48 hours during fermentation. Evaluation of the composition of polyphenols and flavonoids of FC fermented at 48 hours by HPLC revealed hyperoside (quercetin 3-galactoside), luteolin and kaempferol were the major components. The hyperoside content of FC was decreased, while the luteolin and kaempferol contents of FC were increased compared to unfermented Cheonnyuncho (NFC). Evaluation of the anti-obesity effects of FC in 3T3L-1 cells revealed that the accumulation of triglyceride was inhibited by about 27.3% in cells treated with FC at $150{\mu}g/mL$ compared to NFC. These findings indicate FC has the potential for use as an anti-obesity material.

This study compares the quality characteristics of Jeung-pyun prepared by supplementing with rice mash of various cultivars. Results showed high contents of crude protein and crude ash in Saeilmi. The highest and lowest amylose contents were obtained in Goami4 and Baekjinju, respectively. Saeilmi had the highest water absorption index (WAI) of rice flour, whereas the highest water-soluble index (WSI) was obtained in Baekokchal. Maximum viscosity, minimum viscosity, and breakdown were high in Baekjinju, and high cooling viscosity and setback levels were determined in Goami4. The sugar content, total free sugar, and pH of the rice mash were highest in Baekjinju. The highest volume of Jeung-pyun was obtained with Saeilmi supplementation, whereas the specific volume was highest in Baekokchal. Evaluation of L, a, and b color values of Jeung-pyun revealed the maximum L value in Saeilmi, a value in Goami4, and b value in Baekjinju. The physical properties of Jeung-pyun were lower in all supplemented groups compared to the control group for hardness, adhesiveness, and chewiness. The lowest chewiness was obtained in Baekokchal-supplemented Jeung-pyun. We conclude that supplementation with different varieties of rice affects the quality characteristics of Jeung-pyun, which are important factors for manufacturing processed foods.

Banchandeungsok is a book written by a person who lived in the Cheongju area located in northern Chungcheong Province. The literature is regarded as a useful source for showing types of local food in the 1910s, so it was purchased by the National Folk Museum in 2007. The writer categorized dishes described in the recipe section of the book into side dishes, snacks, rice cakes, drinks, and miscellaneous. Following this, each category was distinguished by the name of the dish, the main material, the side material, and the cooking method is presented in tables. Thus, the food culture of Chungcheong Province was arranged based on the above categorized contents. The material from the product and the outside which grow spontaneously divided with the product which flows. The case which is a product the outside, went through what kind of process and could flow toward Sangshin village in Cheongju area probably, to observe tried.

In this study, we attempted to elucidate the cultural characteristics of Korean food based on a traditional understanding on the Korean novel. To achieve this, food characteristics related to 'rites of passage' were analyzed in the representative Korean literary work "Hon-bool", which describes the life of a first-son's wife every three generations in the going to ruin but historic 'Lee's family of Maean district' family and the life of the common 'Geomeong-gul' people who lived with farming on the Lee's land at Namwon of Junbook province in the 1930~1940s, during the Japanese Colonial rule. Every nation possesses rites of passage at important points in life, such as at birth, age of majority, wedding and death. Korean culture, in particular, has several memorial rites relating to birth, death and passage into the afterlife in which special foods are prepared. In this manner, ceremonial foods represent the Korean peoples' traditional vision of the universe and life. The book "Hon-bool" describes these traditions. Especially, the book describes the table-settings related to the main character's childbirth, first birthday, wedding and death. Therefore "Hon-bool" represents a living history of Korean traditional food and the work of storytelling through the traditional understanding is expected that perform an important role in making of cultural contents of Korean foods.

This study was conducted to analyze the nutrition education and diet contents presented in toddler picture books. The study was conducted from August to October 2015 and examined five of Korea's major online bookstores. Finally, we analyzed 296 books, and 67 books contained dietary life contents. The contents of nutrition education were mainly about eating an even diet and keeping good table manners. However, contents of specific, practical dietary guidelines were not included. Therefore, it is recommended to eat a variety of vegetable side dishes at every meal, eat on time and not eat salty, sweet and fatty foods. Most parenting styles on feeding practice for nutrition education were dictatorial. To make parenting styles more effective, the parents' style should be more desirable. In order to provide internal motivation for toddlers and have a positive education effect, teaching methods on eating using picture books should be presented in a positive way. Food often appearing in picture books were vegetables, but green leafy vegetables were hardly observed. Foods that frequently showed up in picture books were pastries, which reflect Westernized food culture.

This study was based on the diary of George Clayton Fork, who arrived in Jeonju at 12:10 p.m. on November 10, 1884 and stayed for two nights and three days. During his stay, he was able to learn about the culture of Jeollagamyoung at that time through food, alcohol, banquets and gifts that he was treated to by gratitude. In particular, Fork added pictures and explanations of the deficiencies to its records, drawing half the breakfast table specially served by the Jeollagamyoung at 10 a.m. on Nov. 11. This is very valuable as the best and first source of knowledge of the food culture of the Joseon Dynasty in Jeonju, where no torture related to food was found. This is the result of a study that put great significance on objectively understanding the culture of Jeollagamyoung in the eyes of foreigners 135 years ago.

This study was carried out in order to analyzed the changes in nitrogen containing taste compounds of three different types of traditional Korean soy sauce with varing ripening period, and to investigates correlation between sensory characteristics and taste compounds contents via contents assay and sensory evaluation of soy sauce samples. Total nitrogen, ammonia type nitrogen and amino type nitrogen contents showed the highest value in Kyupjang. 17 kinds of free amino acid was detected in Chungjangs and 16 kinds of free amino acid was detected in Kyupjang. Nucleotides and their related compounds detected were hypoxanthin, xanthin, IMP, AMP, Inosine, ADP. Free amino acid and nucleotides and their related compounds contents were highest in Kyupjang. Nitrogen related compounds content of high concentration soy sauce ripened over 150 days increased similarly with Kyupjang. In the sensory evaluation of soy sauce taste, Chungjang samples acquired the highest score in the offensive taste test while Kyupjang marked highest score for sweet taste, nutty taste, taste preference. High concentration soy sauce ripend over 150 days yielded the result similar to that of Kyupjang. Sweet taste showed positive correlation with nitrogen compounds. The materials that showed positive correlation with nutty and traditional soy sauce taste and taste preference were nitrogen compound, IMP, AMP. Except for tryptophan, all free amino acid showed positive correlation with nutty and traditional soy sauce taste. Particulary, taste preference correlated to lysine, aspartic acid and glutamic acid.

The purpose of this study was to develop cultural food contents from local dishes related to the historical and cultural heritage in the representative areas of Gurye and Jinan. The information on 'Story' was collected from each region's representative local native journal, searches of related web-sites, analysis of old literature, and interviews of traditional households. 'Telling', the conveyance, was focused on texts of literature analysis, which were synthesized from historical conditions, regional food materials, cuisine, regional symbolism, etc. The created food contents were displayed with balanced and healthy Korean food dishes after nutritional analysis. In Gurye, the content was extracted from the story of Hwang hyun (黃玹, 1855-1910) - figura of Gurye - and his collection, "Maecheonyarok", and the storytelling native food was prepared. In Jinan, the content was extracted from the text of an anecdote from "filial son Kwang-beom Lee", a local journal. We tried to express Gurye's clean image in connection with the patriot - Hwang hyun (his nick name was Maecheon), in the late period of Chosun through the unprocessed and simple nature of the dining table. As in Jinan's storytelling materials, we tried to express a healthy menu of health food for older people based on the clean nature and documents about the real character's filial behavior. The developed healthy menu and dining table properties in this study have been established in accordance with nutrient intake standards of energy in Korea.

This study investigated the quality characteristics and antioxidant activities of Makgeolli (a traditional Korean rice wine) made with Etteum bell flower root (0.5, 1, 1.5, and 2% with steamed rice) during fermentation. The pH values of Makgeolli with Etteum bell flower root powder decreased after 3 days of fermentation and then increased after 5 days of fermentation. Sugar content decreased after 3 days of fermentation. Color evaluation showed the L values of these drinks decreased during fermentation, whereas a and b values both increased. The alcohol content of Makgeolli increased after fermentation, reaching a maximum concentration of 7.90-8.07% by the end of fermentation. Total phenolic compound contents and DPPH radical scavenging activities increased as the ratio of Etteum bell flower root increased. Sensory scores of Makgeolli fermented with 1.5% Etteum bell flower root ware greater than those of Makgeolli prepared by other treatments. Therefore, Makgeolli added with 1.5% Etteum bell flower root added considered to be the most suitable for manufacturing.

The purpose of this study was to investigate the chemical contents (sugar, nitrogen, and amino acids) and sensory characteristics of traditional soy sauce according to three different methods. The samples were taken from four different periods (0, 20, 40, and 60 days after fermentation). Total sugar contents increased in all groups according to ripening period, and Gyupjang (G) showed the highest sugar content among the groups. Total nitrogen and amino acid contents of all groups increased after 60 days of ripening, and Gyupjang (G) and Gyupjang mixed with salt water (SG) had higher total nitrogen content compared to Chungjang (S) at the same period. The results from the sensory evaluation show that preferable sensory characteristics, such as color preferences, sweetness, umami taste, and overall preference, were significantly higher in Gyupjang (G) and Gyupjang mixed with salt water (SG) than in Chungjang (S). Preferable sensory characteristics had significantly high positive correlation with most amino acids, total nitrogen, and sugar contents, except for glutamine. Based on the significant difference in preferable sensory characteristics between Gyupjang mixed with salt water (SG) and Chungjang (S), Gyupjang mixed with salt water (SG) can be used to improve sensory characteristics. This research implies that adding salt water during the manufacturing Gyupjang process is advisable to yield high quality soy sauce.
