Sensory evaluation method was used to develop a type jujube tea the organoleptic properties were evaluated with regard to the optimum sugar content, clarity, drinking temperature and fruit pulp content of the jujube tea. Clarified jujube tea extracted from 25% by weight of dry jujube fruits and 75% water was preferred to those from 15%, 20% and 30% jujube fruites although those from 20% and 30% were not significantly different at 5%level. In spite of the average acceptability score of cloudy jujube tea with 5% of added fruit pulp was not significantly different from that of clarified one, the more fruit pulp in the tea products the worse its acceptability. Cold jujube tea was preferred to warm and hot ones, but these were not significantly different.

식품 12종과 한약재 12종의 에탄을 추출물이 대추·오미자 약선소스의 항산화 및 관능적 특성에 미치는 영향을 알아보았다. 그 결과, 녹차, 쑥, 민트, 레몬 및 부추 등의 식품 추출물과 인삼, 솔잎, 갈근, 모과 및 귤홍 등의 한약재 추출물 첨가시 시료 소스는 높은 항산화능을 보였다. 이들 에탄을 추출물은 페놀성 화합물 함량과 전자공여능이 높고. 과산화물 생성량은 적어 항산화 효과도 큰 것으로 나타났다. 한편 녹차, 쑥, 인삼 및 솔잎 추출물은 특유의 맛과 향 때문에 시료 소스에 첨가시 기호도는 높지않았으나 레몬과 모과 등의 추출물은 강한 단맛과 신맛에 의해 기호도도 증가시켰다. 특히 레몬즙은 대추·오미자 약선소스의 항산화 효과 및 기호도를 높이는데 가장 적당한 것으로 나타났다.

시판대추차 4종의 이화학적, 관능적 품질특성을 제조대추차와 비교하고 전국의 식품영양학과 학생 및 교수 382명을 대상으로 대추차의 품질에 대한 설문조사를 실시한 결과는 다음과 같다. 시판대추차는 3종은 제조대추차에 비해 당도, pH, 투명도, 점도, L, a 및 b값이 낮았다. 그러나 1종은 제조대추차에 비해 점도가 높고 투명도가 매우 낮아 탁하였다. 시판대추차의 관능적 특성은 맛, 감미정도, 대추의 함유정도, 향, 전반적인 기호도면에서 시판 대추차 3종은 제조대추차에 비해 유의적으로 낮은 점수를 나타내었다. 특히, 전반적인 기호도는 제조대추차의 경우 6.1점이었으나 시판대추차는 2.5-3.3점으로 낮았다. 그러나 색은 시판대추차 B 및 C가, 그리고 점도는 C가 제조대추차에 비해 높은 점수를 나타내었다. 전공자들을 대상으로 한 설문조사 결과, 시판대추차는 전통대추차와 '동일하지 않다' 가 50.1%로 많았으며 시판 대추차 대추차에서 개선할 점으로는 대추의 함유정토(30.0%) ＞ 맛(23.8%) ＞ 당도(22.0%)＞향(14.4%)이었다. 관능적 특성치들 중에서 전반적인 기호도와 유의적으로 양의 상관관계를 나타낸 특성은 맛 ＞ 대추의 함유정도 ＞ 향의 순이었다. 이상의 결과를 바탕으로 기업체에서는 시판대추차를 전통적으로 가정에서 만들어 왔던 대추차의 품질에 더욱 가깝게 제조하려는 노력이 있어야 할 것으로 생각된다. 특히, 대추차의 주재료인 대추의 함량을 높여 맛과 향을 개선하는 것이 바람직할 것으로 생각된다.

This study was conducted to investigate the actual conditions of intake of Korean traditional beverages in 273 female university students in Seoul, Korea. The subjects of this study consisted of 128 food and nutrition majors and 145 non-majors. Questionnaires were administered to the subjects who had an average age of 20 years. Two-hundred and nineteen students (80.2%) lived with their parents. Regarding the type of beverages subjects often drink, coffee was the most preferred (51.3%) overall, and non-majors (4.1%) were shown to drink traditional beverages more often. Regarding preference for traditional beverages, most subjects (72.5%) responded that they liked their own traditional beverage. However, for frequency of intake of traditional beverages, 48.7% answered they do not drink any traditional beverages. The reasons why subjects like traditional beverages were taste (71.7%) and health (26.3%), and the type of traditional beverages they often drink were Yulmu tea (35.9%), Sik hae (30.8%), and Yuja tea (10.6%), in order. Regardless of major, ginseng tea, jujube tea, mulberry-leaf tea, Chinese matrimony vine tea, ssanghwa tea, ginger tea, and omija tea were found to be satisfactory traditional beverages. Therefore, due to the low intake frequency, preference, and satisfaction of traditional beverages, new traditional beverages that can meet the standards of female students should be immediately developed.

Green Tea consists of 15-30% catechins (a type of polyphenol), which act as super antioxidants, inhibitory action against aging process. Antioxidants fight radical-free oxygen, an agent which can begin the process of cancer by damaging essential body chemicals and harming DNA. This study was peformed to develop the elderly diet using Green Tea as an inhibitory action against aging process. Nokchaborijook (Baley gruel added rice powder and Green Tea) was manufactured by various levels of Green Tea(1, 4, 7%) and the grinding period(15, 30, 45 sec). The optimum levels of added Green Tea and grinding periods on Nokchaborijook were determined with the results of sensory evaluation by response surface methodology and analysis of composition. The Anti-oxidant Vitamin A, C, E and Flavonoid were increased with increased levels of Green Tea and grinding periods be decreased. As the levels of Green Tea and grinding periods were increased, the green color and penetrated force became stronger. Among the sensory attributes, Bitterness, Green Tea Flavor and Hashness were greater depending on increasing Green Tea. Jujube flavor was greater relying on decreasing Green Tea. Greenness and spreadability of particles were increased as both the amounts of Green Tea and the grinding period were increased. This result was used to determine the optimum conditions of adding levels of Green Tea and grinding periods. The optimum conditions of Nokchaborijook was established as adding of 5.8% Green Tea grinded for 15 seconds.

Objectives : The aim of this study is to analyze the patent trend in Traditional Korean Tea. In this paper, we investigate the diversity of Korean Tea registered as patents focusing on the kinds of medicinal herbs used, processing methods, and types of tea. Methods : We collected patents data using KIPRIS, and WIPS database. We conducted Quantitative Analysis by year and main patentee, and Qualitative Analysis by patent's contents. Results : 313 patents are selected from 2001 to May 2017. The number of patents have been on the rise and reached 44 in 2014. Individuals have registered the most patents, followed by companies, Industry-University Cooperation Foundation, and local autonomous entities. Ginger, Omija and Cactus were used at high frequency among 109 tea containing one medicinal herb. Licorice and Jujube were frequently used among 204 tea containing more than two kinds of medicinal herbs. In classification of patent by efficacy, 'health promotion and function recovery' and 'treatment and prevention of diseases' are most frequently specified. 128 patents are presenting processing methods for medicinal herbs in the order of roasting, fermentation, and fumigation. Among 164 patents presenting tea types, liquid type accounts for more than half and there are 67 leached tea, and 32 powder tea. Conclusion : The analyses results showed that lots of new recipes, efficacy, processing methods and tea types are being studied and registered as patents. In order to help Traditional Korean Tea industry to develop, active patent registration and further study about up-to-date patent trend would be required.

This study was to investigate the factors affecting drinking Korean traditional beverages and the drinking habits of college students in Seoul. The research was carried out by asking them to drink 10 kinds of traditional drinks. They were composed of 45.5% of boys and 54.5% of girls who were $18\sim21$ years old, studying food related science (63.9%), and mostly (86.6%) living in a nuclear family in collective residents (60.4%) like an apartment. The number of students whose family's monthly incomes were over 3 million won was the largest as 37.1%. Their mothers were housewives (58.4%) mostly aged $46\sim50$ as 47.0%. In the research on the preference of students for the traditional drinks, most of them, 78.7%, showed their liking for the drinks because of their good taste (61.%). The number of students who answered they got the drinks by homemaking was the largest as 39.6%. Most of them, 66.3%, preferred fruit drinks, 19.8% soda drinks, 11.4% traditional drinks and 2.5% functional drinks. 31.2% of the drinks mostly taken at home was green tea, followed by sweet rice drink, Shik-hae.

본 연구는 식품위생법과 약사법으로 관리 되고 있는 한방차 원료의 잔류농약 오염실태를 비교 조사하고자, 다성분 둥시분석법으로 총149건을 검사하였다. GC-ECD 와 GC-NPD를 이용하여 잔류농약을 검사한 결과 22건에서 24종의 농약 성분이 검출되었으며, 농산물에서 검출률은 20.3%, 한약재에서 검출률은 8.6%로 의약품 관리대상인 한약재보다 식품공전 규제대상인 농산물에서 검출률이 높았다. 주요 검출 품목은 구기자와 대추로, chlorpyrifos, chlorothalonil, hexaconazole 등 다양한 성분의 농약이 검출되었으며, 그밖의 천궁, 길경, 산수유, 감국, 황기 등에서 농약이 검출되었다. 검출 농약의 대부분은 유기인계(29.2%)였으며, 피레스로이드계(16.7%), 유기염소계(12.5%) 순으로 나타났다. 검출된 농약의 농도는 모두 기준 이하였으며, 식품공전 및 생약 등의 잔류오염물질 기준 적용이 가능하였다. 반면, 산수유, 천궁에서 다수의 농약이 다량 검출되었으나 천궁의 chlorfenapyr만이 0.05 mg/kg 기준이 설정되어 있고 나머지 성분은 가공계수적용 등의 문제로 기준 적용이 어려웠다.
