  • 허브와 유카는 차나 의약품, 화장품, 향신료 등에 널리 이용되고 있는 식물로써 본 연구에서 레몬 버베나, 스피아민트, 애플민트, 코리아민트(박하), 로즈마리, 파인애플세이지, 감국, 스테비아, 라벤더, 그리고 레몬 바베나 10종에 허브 및 각 단일종 허브에 0.02% 유카를 첨가하여 80℃에서 우려낸 차의 pH 및 가용성 고형물 양을 조사하였다. 허브차 단독보다는 유카를 첨가하였을 때 레몬바베나, 스피아민트, 애플민트, 박하, 그리고 로즈마리의 pH는 약간 감소하였으며, 고형물 함량에는 변화가 거의 없었다. 관능평가에서 허브차와 유카혼합차의 경우 몇몇을 제외하고는 큰 차이를 보이지 않았고, 향, 색, 맛, 그리고 전체적인 기호도에서 전체적으로 박하가 가장 좋은 것으로 나타났으며, 박하에 유카를 혼합했을 때 pH는 혼합농도가 높을수록 계속 감소하였으며, 관능평가 결과는 저농도(0.01∼0.04%) 첨가시 향상하였으나 그 이상 첨가시 오히려 선호도가 낮은 것으로 나타났다. 따라서 유카를 허브 차에 저농도로 혼합하여 관능에 영향을 주지 않으면서도 새로운 기능성을 갖는 유카허브차를 개발하는데 그 가능성을 보여줄 뿐만 아니라 허브 중에서 특히 박하와 유카혼합차의 개발 가능성을 보여주었다고 생각된다.

  • Tofu samples with added herbs (green tea, rosemary, lavender and thyme) were prepared. The yield of the herb tofus was higher than that of the control tofu. The L value of the control tofu was higher than that of the herb tofus, whereas the b values were lower. The herb tofus had generally lower pH than the control tofu. Especially, lavender tofu showed the lowest pH. Under SEM examination, the control tofu showed a rough folding surface, whereas the green tea and lavender tofus had small air cell size and smooth surface. Most textural characteristics did not show significant difference among the tofu groups. However, chewiness and hardness of the thyme tofu were the lowest. In the sensory evaluation, the herb tofus had low scores in air cell size and a beany smell, but high scores in herb smell and hardness.

  • Objectives : The aim of this study is to analyze medicinal herbs, the ingredients of traditional Korean Tea, focusing on efficacy in the traditional Korean medicine. Through this study, for vitalizing traditional Korean Tea market, the researchers attempt to explain the superiority of traditional Korean Tea. And it will be used basis data on further traditional Korean Tea. Methods : We conducted a research targeting traditional Korean Tea in domestic market from June through December 2014, and finally 205 kinds of Tea were selected and analyzed. Results : 48 kinds of medicinal herbs were used alone as ingredients in the traditional Korean Tea containing just one medicinal Herb. and 87 kinds of medicinal herbs were used as ingredients in the traditional Korean Tea containing more than two kinds medicinal Herbs. In the classification of the medicinal Herbs by part for use, roots and rhizome is most used. In the classification of efficacy of medicinal herbs, tonifying and replenishing medicinal herbs are most popular as ingredients in the traditional Korean Tea. Conclusions : Medicinal herbs have been widely used in the traditional Korean Tea. Tea consumers concern about not only the efficacy but also the taste, scent and color.

  • 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.

  • The efficacy of a medicinal herb tea (MHT) for assisting smoking cessation and for reducing withdrawal symptoms was evaluated by a placebo controlled subjective test in 100 male smokers. The MHT group experienced less craving for the taste of tobacco, and was more successful at quitting smoking. Among the subjects continuing to the final stage, 23 subjects (38.3 %) who took the MHT and 2 subjects (10.0 %) who took the placebo tea succeeded in quitting smoking. In the group taking MHT, urinary cotinine concentration increased during the first 2 weeks and then greatly decreased from weeks 2 to 4. The urinary cotinine concentration in the MHT group at week 0 was 38.6 mol/L but decreased to 24.5 mol/L by the end of week 4. MHT also reduced withdrawal symptoms, a frequent reason for failure in reducing or quitting smoking. The effects of the herbal tea on smoking cessation and withdrawal symptoms may be attributed to increased metabolism of nicotine and other effects of unidentified components of the herbal ingredients.

  • Antioxidant activity and nicotine degradation activity (NDA) of 21 medicinal herbs were determined by using a 1,1-diphenol-2-picrylhydrazyl (DPPH) method and a PLC/PRF5 human liver cell line method, respectively, to develop an anti-smoking aid. The highest and lowest antioxidant activities represented by $IC_{50}$/ value were 30 $\mu$g/mL of Eugenia caryophyllus and 3,270 $\mu$g/mL of Panax ginseng C. A. Meyer, respectively. Antioxidant activity of Eugenia caryophyllus was equal to 38.0$\pm$1.2 mg VCEAC(vitamin C equivalent antioxidant capacity)/ g herb. The highest and lowest NDA values were 1.81 of Astrgalus membranaceus Bunge and 1.01 of Raphani seed and Lespedeza tomentosa Sieb, respectively. Eleven medicinal herbs with high antioxidant activity and/or NDA were selected to make an herbal tea. The herbal tea had high antioxidant activity (50 $\mu$g/mL $IC_{50}$/ and 22.4$\pm$1.4 mgVCEAC/g) and NDA (1.243). The medicinal herb tea could help smokers quitting smoking by degrading and exhausting nicotine accumulated in body and removing reactive oxygen species.

  • 본 연구에서는 천연 허브류의 항산화성 및 세포주를 이용한 세포 독성, 산화적 스트레스에 대한 보호 효과, 항산화 효소 활성 등을 살펴보았다. Chinese Hamster lung fibroblasts인 V79-4에서는 green tea 추출물, 고농도의 lemon 추출물에서 세포독성을 보였다. H$_2$O$_2$로 유발한 산화적 스트레스에 대해 허브 추출물의 V79-4 세포 보호효과는 모든 추출물이 농도 의존적으로 효과를 갖지는 않으나chamomile, fennel, dandelion을 제외한 대부분의 고농도추출물에서 대조군에 비해 세포 보호 효과를 가지고 있다고 보인다. 항산화 활성 및 세포 독성 실험을 토대로 활성이 높은 5가지 허브 추출물의 V79-4 세포를 이용한 항산화 효소 활성에서 lemon vervena, chamomile을 처리하면 superoxide dismutase, glutathione peroxidase 활성이 대조군보다 증가하는 결과를 보였다. 이러한 다양한 허브 추출물의 항산화 활성 검색을 토대로 허브류의 식품 소재로서의 가능성을 평가할 수 있을 것이다.

  • The purpose of this research was to investigate the effects of herbs, including rosemary, thyme, oregano, ginger, and green tea, on the quality characteristics and antioxidant activity of Yagkwa. After 16 days of storage at $60^{\circ}C$, all the herb-added samples showed significantly lower values for acid, TEA and peroxide than the control. The samples with rosemary and thyme showed significantly higher antioxidant activities than the other samples. The samples with rosemary and ginger showed significantly lower L-values than the control sample and the samples with thyme, oregano and green tea showed significantly lower a-values than the control. For the b-value, the control sample had the highest value. In the sensory evaluation of the Yakgwa, there were no significant differences between the samples in terms of color, flavor and texture. For overall acceptability, the rosemary-added sample showed the highest score among the samples and the thyme-added sample showed a significantly lower score than the control. In the texture analysis, all the herb-added samples, except for green tea, showed higher hardness than the control. In conclusion, the addition of herbs would be a useful way to enhance the antioxidant quality of yakgwa and rosemary would be the best choice when considering antioxidant activity and sensory characteristics.

  • 본 연구에서는 일상생활에서 손쉽게 음용할 수 있는 차 추출물에 대해 항산화력과 항산화 성분의 함량을 측정함으로써 그 상관관계를 알아보고자 하였다. 차 추출물의 항산화력은 ABTS 와 DPPH radical을 사용하여 측정하였으며, 항산화력 성분은 총 폴리페놀, 총 플라보노이드, 총 비타민 C 함량을 각각 측정하였다. 총 폴리페놀 함량은 홍차, 허브티 I, 녹차 I, 허브티 II, 녹차 II, 한차 I에서 101.51~62.60 mg범위로 다른 차에 비하여 높게 나타났으며, 총 플라보노이드 함량은 허브티 II, 한차 I, 홍차에서 높은 함량을 나타내었다. 반면 총 비타민 C의 경우 한차 I이 15.78 mg을 나타낸 제품을 제외 하고 다른 것들은 모두 낮은 함량을 나타내었다. 항산화력이 높게 나타난 차는 주로 녹차류와 홍차였으며 이들의 항산화력에 기여하는 물질이 주로 비타민 C나 플라보노이드가 아닌 폴리페놀성 화합물임을 알 수 있었다.
