This study was conducted to evaluate the prediction of sensory property of smoke from the leaf chemical property and characterize leaf chemical components for the best tobacco taste's leaves in burley tobacco. For analytical and sensory evaluations, sixteen grades were used. The major leaf chemical components to predict the sensory property of smoke were ether extract for tobacco-like, chloride for impact and total nitrogen/nicotine for irritation. Within ${\pm}20\;%$ range of difference, the predictable probabilities of sensory property of smoke from the leaf chemical properties were 100 % for tobacco-like, impact and irritation. As a result of K-means cluster analysis on the basis of tobacco taste, the desirable leaf chemical component contents were $6.5{\sim}6.8\;%$ in ether extract, $0.25{\sim}0.30\;%$ in chloride and $1.26{\sim}1.54$ in total nitrogen/nicotine ratio. This study suggest that the some regression equations may be useful to predict the sensory components of tobacco smoke from a few selected leaf chemical properties in burley tobacco and to select the burley tobacco leaves for enhance the tobacco taste of cigarette.

This study was conducted to evaluate the prediction of sensory characteristics of smoke from the leaf chemical compounds and characterize leaf chemical components for the best tobacco taste's leaves in oriental tobacco. For analytical and sensory evaluations, seventy two grades were used. Sensory evaluation of tobacco smoke for six attributes were scored on fifteen-point scale by $10{\sim}14$ expert panels trained to estimate smoking quality quantitatively. The major leaf chemical compounds to predict the sensory characteristics of smoke were ether extract for tobacco-like, nicotine for impact and total nitrogen/nicotine ratio for irritation, and total sugar for off taste & odor. Within ${\pm}20%$ range of difference, the predictable probabilities of sensory characteristics of smoke from the leaf chemical compounds were 87.5 % for off taste & odor and $94.4{\sim}98.6\;%$ for tobacco-like, impact and irritation. As a result of K-means cluster analysis on the basis of tobacco taste, the desirable leaf chemical compound contents were $5.9{\sim}8.3\;%$ in ether extract, $1.35{\sim}2.27\;%$ in nicotine and $1.17{\sim}2.24$ in total nitrogen/nicotine ratio. This study suggest that the some regression equations may be useful to predict the sensory characteristics of tobacco smoke with a few selected leaf chemical compounds in oriental tobacco and to select the oriental tobacco leaves by means of enhancing the tobacco taste of cigarette.

류충렬(Chung-Ryul Ryoo),박성원(Seong-Weon Park),이한영(Hanyeang Lee) 한국암석학회 2014 암석학회지 Vol.23 No.1

한반도 남서단부의 영암광화대에는 상은과 은적 그리고 바람재 광산이 발달하고 있다. 이 지역은 목포-해남-영암 지역에 걸쳐 확인되는 대규모 화산성 환상구조의 북동부에 해당한다. 조사지역인 상은-은적-바람재 지역에서 확인된 13개소의 석영맥과 광화대는 유문암질 용결응회암을 모암으로 하고 있으며, 주로 남-북 내지는 북북서 방향의 주향에 서측으로 고각도를 이루고 있다. 상은, 은적, 바람재 지역에 발달하는 석영맥은 단일맥인 경우도 있으나, 주로 폭 1-5 cm의 맥들로 다발을 이루는 특징을 보인다. 석영맥과 평행하게 발달하는 단층면의 발달로 보아 석영맥의 관입과 광화작용이 전후에 단층운동이 존재했음을 지시한다. 또한 이들 석영맥과 광화대는 광화작용 후기에 작용한 북서 방향의 좌향이동 단층에 의해 변위된 양상을 보인다. 북서 방향의 단층은 불치와 상은광산 부근에서 잘 관찰되며, 장동리와 장천리 일대의 석영맥의 분포나 선상구조에 의해서도 이 단층과 평행한 단층들이 발달할 것으로 판단된다. 조사지역이 서측인 상은적산 남측에서 서측으로 북서 주향의 석영맥이 관찰된다. 은적-상은 광상 주변에서 확인된 12개 석영맥의 현장조사 및 금, 은 품위의 분석 결과에 의하면, 남측으로 가면서 석영맥의 발달 양상이 미약해 지고 있다. 바람재 부근 광상의 경우 북북서-남남동 방향의 석영맥이 약 20m 연장되고 있다. 섬아연석, 방연석 등 유화광물은 함유하고 있으나 금-은의 발달은 미약하다. 금품위가 평균 <0.1 g/t, 은품위가 평균 5.7 g/t으로 은적광산(금, 12.3 g/t, 은, 1,380.0 g/t)과 상은광산(금, 2.7 g/t 은, 23.5 g/t)에 비해 남측으로 가면서 금, 은의 품위는 현저히 떨어지는 반면, 그 외 연, 아연 등 유화광물 함량은 증가하는 양상을 보인다. The Yeongam mineralized zone is located in the southwestern part of the Korean peninsula, including the Sangeun, Eunjeok and Baramjai miners. This zone is located in the northeastern part of the Mokpo-Haenam-Yeongam volcanic circular structure. The 13 sites of quartz vein with mineralization are developed in the Sangeun-Eunjeok-Baramjai area, within rhyolitic welded tuff, showing N-S or NNW tend with highly dipping to the west. The quartz veins occur as a single vein or a bundle of veins with width of 1-5 cm in each. The existence of faults parallel to the quartz veins indicates that the faulting occurred before and after the development of quartz veins and mineralization. The quartz veins and mineralized zone are displaced by NW-trending sinistral strike-slip faults. The extension of the Sangeun-Eunjeok mineralized belt is traced to the south, following a NNW-trending tectonic line, and the Au-Ag contents are analysed in the 12 sites of quartz veins. Contents of gold and silver are 12.3 g/t and 1,380.0 g/t in Eunjeok mine, 2.7 g/t, 23.5g in Sangeun mine, and <0.1 g/t, 5.7 g/t in Baramjai mine respectively. Therefore, a highly Ag-Au mineralized zone is not developed in the southern part of the studied area.

This study was carried out to clarify the effects of phytohormone, carbon source, and temperature on the growth of calluses induced from the crown gall tumor of Nicotiana tabacum var. Bright Yellow 4. Crown gall tumors were induced from stem tissues of Nicotiana tabacum var. Bright Yellow 4 by Agrobacterium tumefaciens. Therefore, it was clarified that genes on a special area of Ti-plasmid, called T-DNA, became integrated and expressed in the nuclear DNA of Nicotiana tabacum var. Bright Yellow 4. The crown gall tumor tissues could be cultured on the media which did not contain any auxins or cytokinins, and white and compact calluses were observed. However, normal tissues did not grow in vitro in the absence of the phytohormones. The tumor calluses were formed profusely when cultured on the media supplemented with IAA. On the other hand, the tumor calluses tended to be formed more profusely on the medium supplemented with 5mg/ℓ IAA. The media with cytokinins, kinetin and BA, produced poor result. As for the effect of carbon sources on the growth of tumor calluses, the calluses were formed on the media with sucrose more profusely than on the media with glucose. The concentration of sucrose used for callus induction from tumor tended to be lower than that for callus formation from normal tissus and the most effective concentration of sucrose was 20 g/ℓ And the optimal temperature for the growth of tumor callus was 25℃.

A cDNA fragment, named PVY-CP, encoding coat protein (CP) of potato virus Y (PVY-VN) was obtained by RT-PCR. The PVY-CP cDNA was manipulated to construct an untranslatable form in which three stop codons are introduced near the start codon by site-directed mutagenesis. The untranslatable PVY-CP cDNA was inserted into plant expression vector and transferred to Nicotiana tabacum cv. NC 82 by Agrobacterium-mediated transformation method. The untranslatable PVY-CP cDNA transformed plants were regenerated and PVY resistant transformants were selected based on symptom development after mechanical inoculation. Genomic PCR and Southern blot analysis confirmed that one or more copies of the untranslatable PVY-CP cDNA was integrated into the genome of tobacco plants which are highly resistant to PVY.

안명수,박성원 한국조리과학회 1994 한국식품조리과학회지 Vol.10 No.1

대두유와 라아드의 항온저장 및 가열시 methionine과 lysine의 첨가농도에 따른 항산화 효과 및 기존 항산화제들의 항산화력에 대한 상승효과를 비교 연구하였다. 유지의 항온(60±2℃) 저장시 methionine과 lysine을 각 농도별로 첨가한 경우 모든 시료에서 항산화 효과를 보였으며 그 중에서 methionine을 1% 첨가하였을 때 가장 효과가 좋았고 그 정도는 TBHQ를 첨가한 경우와 유사하였으며 tocopherol 보다 월등히 높은 항산화 효과를 보였다. 그리고 이들의 항산화 효과는 농도증가에 따라 비례적으로 증가하였으나 농도간에 큰 차이는 없었다. 즉 이들의 항산화 효과는 TBHQ>methionine 1%>methione 0.1%>methionine 0.02%>lysine 1%>lysine 0.1%>lysine 0.02%>tocopherol 순이었다. 또한 아미노산, TBHQ, tocopherol 모두 식물성유 보다 동물성 유지에서 더 큰 항산화력을 나타내었다. 유지 가열(180±2℃)시 methionine과 lysine을 각 농도별로 첨가한 모든 시료에서 항산화 효과가 나타났고 TBHQ는 자동사놔시와는 달리 항산화 효과가 크게 떨어졌으며 이들의 항산화 효과의 크기 순서는 methione 1%>methionine 0.1%>methionine 0.02%>lysine 1%>lysine 0.1%>lysine 0.02%>tocopherol, TBHQ 순이었다. Methionine 및 lysine을 tocopherol, ascorbic acid, citric acid와 혼합하여 대두유에 첨가하였을 때 tocoperol과의 혼합물이 가장높은 상승효과를 나타내었으며 ascorbic acid 및 citric acid와의 혼합물도 약하지만 상승효과를 나타내었다. 따라서 methionine과 lysine은 유지에 대하여 항온저장 또는 가열시 모두 항산화 효과가 있으며 특히 가열시와 동물성 유지에 대하여 그 효과가 우수하고 식품 항산화제에 대한 상승효과도 크다는 것을 알 수 있었다. Soybean oil and lard containing different level (0.02, 0.1, 1%) of methionine, lysine and some antioxidants (TBHQ, α-tocopherol) were stored at 60℃ and heated at 180℃ to compare their antioxidative effects. Peroxide values (POV) and acid values (AV) of each oil were monitored. Methionine and lysine showed antioxidative effects in all concentration and the higher concentration, the higher effect. In case of incubating antioxidative effect of methionine was similer to that of TBHQ and that of lysine was considerably higher than that of α-tocopherol, but was lower than that of methionine. In case of heating the antioxidative effects of methionine and lysine were showed higher than those of TBHQ and α-tocopherol. Methionine and lysine also had higher antioxidative effects in animal fat than in vegetable oil. Synergistic effects among methionine, lysine and some food antioxidants were shown to be available in all substrates and the best effect was shown in substrate added compound of methionine and α-tocopherol.
