“Sujeonggwa” is a traditional korean beverage made from dried persimmon, cinnamon, and ginger and is oftengarnished with pine nuts. The purpose of this study was to investigate changes in the ingredients, recipes, and processingof “sujeonggwa” in Korean cookbooks published since 1400. The name sujeonggwa is derived from jeonggwa. In the early1600s, sujeonggwa was used in ancestral rites and as a reception beverage, although we don't know its cooking method.According to the literature of the early 1800s, sujeonggwa was made from various fruit ingredients such as pear and yuzu.But since the late 1800s, it has been mostly made from dried persimmon based on ginger and cinnamon boiled with water.Garyeon-sujeonggwa is made with lotus leaf while japkwa-sujeonggwa is made with pear and yuzu. Japkwa-sujeonggwa issimilar to hwachae in terms of ingredients and cooking method.

The purpose of this study was to investigate the effects of perceived price and servicescape on employee service quality, food and beverage quality, and customer value in Daegu Korean restaurants and to suggest methods for them to become the food mecca of Korea and the world. The samples for this study were customers of nine Korean restaurants in Daegu. A total of 368 questionnaires were analyzed with factor analysis, a reliability test, and a covariance structural analysis. The results showed that perceived price was positively related to employee service quality and food and beverage quality and that servicescape was positively related to employee service quality and food and beverage quality. However perceived price, servicescape, employee service quality, and food and beverage quality were not related to customer value. The reasons were that these factors did not influence perceived customer value in Daegu Korean restaurants. The Daegu municipal office should require these restaurants to develop distinguished employee service and food and beverage quality and conduct consistent marketing to Koreans and westerners, so that these restaurants can become the food mecca of Korea and the world.

Alcoholic beverages can be viewed as repositories of historical information reflecting agricultural environment, economic and scientific level, religion, literature and art of their country. Korean Alcoholic beverages are based largely on rice, which have been developed in the following order: Takju, Cheongju and distilled spirits, Soju. They are closely related with the development of agriculture and historical levels of science and technology, and thus can be seen as symbolizing economic and political changes as well as rises and declines throughout the culture's history. The present review assessed the past and present flows of Korean alcoholic beverage culture, which has had a significant influence on the mental world of Korean people, based on literature concerning the history of food in Korea. Another focus of the study was a discussion on the future transmission and refining of Korean alcoholic beverage culture, which is undeniably informed by the Korean people's unique imagination and cultural sense.

This study was performed to investigate the perception and the preference of Korean traditional foods such as traditional holiday foods, rice cakes and beverages. The subjects were 598 elementary school students(male 310, female 288) in fifth or sixth grades. The most favorite traditional holiday food was rice cake soup(57.4%) and 92.4% of subjects wanted to keep the traditional holiday foods because of the traditional custom. The traditional beverages mainly drinking at home were sikhye(35.6%), misugalou(30.2%), green tea(18.5%), etc. Children's most favorite beverage was misugalou(90.5%) and they had no taste for ginseng tea(39.6%). Children did not know well about booggumi(64.1%), dootubdduk(63.3%), whajun(39.6%), etc. and liked gguldduk(94.2%) better than the others. They liked the rice cake because of its good taste(69.0%) and disliked it because of chocking(30.9%), not eating frequently(29.5%), hard and tough(18.2%), and so on. And they wanted to make the rice cake softer and sweeter like the cake and mostly ate it on the traditional holidays.

Traditional Korean beverage can be divided into Jang, Gahl Soo, Mi Su, Soo Jung Gwa, Shick Hae, Tahng, Hwa Chae, Sook Su, and Tea according to ingredients and how it is proccessed. The purpose of this study was to investigate the Korean beverage percetpion and to analyze the factors (sociodemographic factors and life-style related factors) which influence percetpion of Korean beverage. Questionnaries were hand delivered to 2,200 subject residing in Seoul and 1,884 questionnaris were collected : resulting in 84% response rate. Statistical data analysis was completed using SAS Package program for the analysis of covariance(ANOCOVA).The results are as follows: (a) Survey on Korean beverage perception showed that the recognition rates of ShickHae(58.4%), Cition Tea(53.5%), Sung Nung(48.7%) and Soo Jung Gwa(40.8%) were high, whereas those for Tahng, Jang, and Gahl Soo were low.(b) About 40% of respondents performing 4 kinds of Korean traditional ceremony a year The percentage that reported they purchased Korean beverages was 44.0%, higher than the 38.5% that answered they made Korean beverage at home.(c) In analyzing the factors which influence beverage perception, the sociodemographic factors variously influenced perception rate depending on beverage. Age and sex had influenced on perception rate of Shick Hae and Donggulre Tea. Income level influenced on the perception rate of Sung Nung and Citron Tea. Sociodemograhpic factors like senior over 50s, female and extended family size had positive influence on the perception rate.

Fermentation characteristics of kwahaju (a typical Korean traditional alcoholic beverage) base were investigated during fermentation with different contents of nuruk (Korean-style bran koji) extract. The nuruk extract which was prepared by incubating the mixture of nuruk powder and water at 25℃ overnight and by filtering it was used to be 0.6%, 2.7%, 5% and 10% (v/v). Total and reducing sugar contents as well as acidity of the kwahaju base with 0.6% nuruk extract were higher than those with 2.7%, 5% and 10% at the fermentation end. Final pH values of all the base samples were ranged from 3.3 to 4.1. Alcohol concentrations of the base samples with 2.7%, 5% and 10% nuruk extract were higher than those with 0.6%. Microbial growth rate was great and inner temperature was high in the sample with high content of nuruk extract, but fermentation period was short. Total sugar consumption and alcohol production increased as the content of nuruk extract increased, but total acid production decreased. The base sample with 10% nuruk extract showed the most excellent fermentation efficiency. Fusel oil content of the base sample with 2.7% nuruk extract was the highest (457.3 ppm), and those wity 5% and 10% nuruk extract were 438.9 ppm and 442.6 ppm, respectively. The sample with 0.6% nuruk extract had the lowest content (409.5 ppm). Sensory evaluation of both the kwahaju base and kwahaju mix with 25% and 40% alcohol by adding soju (Korean distilled liquor) showed that the base with 2.7% nuruk extract had the highest score, and that the kwahaju mix with 25% alcohol had higher score than that with 40%. The sensory results on overall desirability were consistent to those on color and alcohol concentration, and it turned out that the two factors were important to make kwahaju.

Fermentation characteristics of Baikhaju (a typical Korean traditional alcoholic beverage) were investigated during fermentation with differently treated rice samples, which were steamed rice (SR), plain steamed rice bread (RB), rice porridge (RP) and roasted rice (RR). The RB sample showed an excellent fermentation efficiency with the highest alcohol production (20.84%). The SR and RR samples showed 17.79% and 17.31% of alcohol production, respectively. The RP sample was the lowest alcohol production (11.47%). The pH values of all the beverage samples were similar and were ranged from 3.6 to 3.9. The fermentation periods of RB and RR samples were longer than the SR and RP. The inner temperature and microbial growth in all the beverages increased at each of input steps of the rice and Nuruk (a Korean-style bran koji). Fusel oil content of the SR and RP samples (613.6 ppm) was higher than that of RR (482.7 ppm). The RB sample with the best fermentation efficiency had the lowest fusel oil content (341.8 ppm). The RP sample showed the highest score in sensory evaluation and RB sample showed the lowest. The results on sensory evaluation were contrary to those on the fermentation efficiency.

Physicochemical and sensory characteristics of Korean traditional alcoholic beverages, such as Kwahaju, Sokokju, Baikhaju, Samhaeju and Hosanchun were investigated during fermentation with the difference of input step and treatment of rice and Nuruk (Korean-style bran koji). pH values in all treatments were similar to be ranged 3.1~3.2, but acidity of the treatment brewed without seed mash was 1.5~2 times higher than that of the treatment brewed with seed mash. The concentration of alcohol in all treatments increased as the concentration of the Nuruk increased. The alcohol concentrations of Samhaeju and Hosanchun ranging from 6.5% to 7.7% were higher than those of Kwahaju, Sokokju and Baikhaju ranging from 7.9% to 10.6%. Residual reducing sugar contents of Kwahaju, Sokokju and Baikhaju ranging from 4.6 g/L to 9.7 g/L were lower than those of Samhaeju and Hosanchun ranging from 14.2 g/L to 15.5 g/L. The consumed total sugar contents of Kwahaju, Sokokju and Baikhaju ranging from 125.4 g/L to 159.2 g/L were higher than those of Samhaeju and Hosanchun ranging from 111.2 g/L to 123.8 g/L, and the treatments brewed with seed mash showed more sugar consumption than the treatments brewed without seed mash. Sensory quality in the treatments brewed with seed mash was better than those of without seed mash. Concentration of Nuruk and preparation of seed mash from it were critical factors compared to input step and treatment of rice in Korean traditional alcoholic beverage brewing.

백삼과 홍삼의 추출수율은 각각 33.56%와 48.79%로 홍 삼의 추출수율이 높았고, 산성다당체의 경우 1~4차 추출단 계까지는 홍삼군이 백삼군보다 높았으나, 5차 추출단계에 서 백삼군이 6차 추출단계에서는 홍삼군이 높게 나타났다. 백삼과 홍삼의 추출단계별 농축액의 조사포닌 함량은 백삼 (56.44 mg/g)에 비해 홍삼(53.15 mg/g)이 약 5.8 % 증가하는 것으로 나타났다. 이들을 혼합한 선택적 홍삼농축액 모델 4종의 기호도 평가 결과 1, 2, 6차 추출물이 혼합된 RGB-4가 가장 높은 기호도를 나타내었고 시판 홍삼 농축액 3종에 대해 비교한 결과에서도 RGB-4가 쓴맛, 떫은맛, 인삼향 강도가 약해지 고 종합적 기호도에서 높은 평가를 받았다. 본 실험에서는 추출방법을 달리 함으로써 추출수율 및 조사포닌 함량을 감안하여 인삼 쓴맛과 향의 강도를 낮출 수 있다는 것을 확인하였다. 이 추출방법을 이용하여 쓴맛 을 저감시키고 인삼향미의 강도를 저감시킨 제품을 개발하 여 좀 더 편하고 자연스럽게 홍삼제품을 접할 수 있도록 더 많은 연구가 진행 되어야 할 것이다.
