  • A rapid processing method for fermented sauce of favorable flavor was investigated with low-usefulness marine resources. Hydrolyzed at optimal conditions for 6 hours usuing alcalase, and separated by molecularporous membrane. It's very effective for remove bitter taste at below M.W. 100 dalton, and effective at below M.W.500 dalton. Added 2% invert sugar in fermented sauce at below M.W.500 dalton, and thermal treatment at 100$^{\circ}C$ for 30 minutes were improved flavor. Chemical composition of fermented sauce using hair tail were 80.7% of moisture, 2.2% of carbohydrate, 1.8% of total nitrogen, 1.6% of amino nitrogen and pH was 6.5. The ratio of amino nitrogen in total nitrogen was 77.8%. And chemical composition of fermented sauce used gizzard shad, kangdale, pen shell and oyster were similar to fermented sauce used hair tail. Total nitrogen were above 1.8% and the ratio of amino nitrogen in total nitrogen was 77.7∼84.2% in all fermented sauce. Amino acid contents in fermented sauce used hair tail, gizzard shad, kangdale, pen shell and oyster were 4,318.1mg%, 4,681.3mg%, 3,156.2mg% and 4,175.0mg%, respectively. And the predominant free amino acid were glutamic acid, lysine and glycine in all fermented sauce.

  • This study was carried out to assess the dimensional stability of wood material treated by plastic processing for bentwood and compression wood. The evaluation method was different between two wood materials, but the treatments for them were very similar to each other. One of the main methods is heat treatment with sufficient water vapor. In bentwood, the used species were painted maple (Acer mono), bitter wood (Picrasma quassioides) and birch (Betula schmidtii). Steaming was the worst treatment method for dimensional stabilization of bentwood. The best results could be attained with PEG treatment for dimensional stabilization of bentwood. Dimensional stability of bitter wood was found to be conspicuous. However the steaming treatment at lower temperatures, i.e., about $130^{\circ}C$ was not suitable for dimensional stability of bentwood. In compression wood, the used specimen was Italian poplar wood (Populus euramericana). Two heat compressive pressing conditions, an open-press system and an air-tighten closed-press system, were used. The recovery rate was measured after boiling and/or absorbing in water to estimate the dimensional stability of heat compressed wood. The best dimensional stability of compressed wood in the air-tighten closed-press system was found to be better at $200^{\circ}C$ than $180^{\circ}C$. The best compression rate for dimensional stability was 73 percent.

  • The fourteen different electrodes coated with polymeric lipid membrane were evaluated to selectively monitor the sweet, salty, sour and bitter tastes, and umami. The polymeric lipid membrane consisted of the three components, or polymer matrix, plasticizer and electroactive material, the compositional ratio of which was 1:1.25:1. Herein, the 14 different electroactive materials were used. Sucrose, NaCl, citric acid, caffeine and MSG were used as standard materials of sweet, salty, sour and bitter tastes, and umami. The linear responses of each electrode regarding 5 tastes were analyzed by means of the correlation coefficient between electric potential difference and concentration of a taste material when the linearity was based on a linear model and a thermodynamic model, respectively. As fur salty taste, the electrode coated with valinomycin had a selective linearity at the significance level of 0.01. For monitoring sweet taste, the electrode with oleylamine and the electrode with the mixture of tai-n-octylmethylammonium chloride and dioctylphosphate (2:8) showed the significant linearities at the levels of 0.05 and 0.10, respectively.

  • 사과 탄저병은 매년 특정기간의 과실에 한하여 발병한다는 것으로 미루어 보아 지간에서 자낭각의 형으로 월동하는 것으로 보고 연구한 결과는 다음과 같다. 1) 사과, 포도, 아까시아 등의 공시나무가지에 병균이 감염되어서 포자퇴가 형성되는 것으로 보아 본 병균은 나무가지에서 월동이 가능한 것으로 생각된다. 우리나라에서는 발견하지 못했던 자낭세대가 접종된 공시나무가지의 병환부의 껍질속과 병과의 표피밑에서 검출되었으므로 자낭각의 형으로 지간에서 월동하여 일차전염원이 될 수 있다는 사실을 알았다.

  • Bitter melon (Momordica charantia, MC) has been used in traditional Korean medicine in treating diabetes. In addition, some reports were emerged, showing the antifertility activities of MC in mammals. We investigated the effects of ethanolic MC extract on the reproductive activity of golden hamsters whose spermatogenetic capacity is controlled by their photoperiods. The animals were divided into 4 groups: long photoperiod (LP) control, short photoperiod (SP) control, and LP animals treated with MC. The animals were orally ingested with low (0.03 g/kg) or high (0.15 g/kg) concentrations of the ethanolic extracts for 8 weeks on the daily basis. The control animals received the vehicle. The animals were then mated with age-matched females, experienced pregnancy. As results, the LP control animals showed active large testes but SP control animals displayed remarkably reduced testes. The animals treated with both concentrations of MC extracts demonstrated large testes, indicating fertile activity as animals in LP. LP control animals had litters as expected, but SP controls had no litters at all. MC extract showed the same results as LP animals in generating offsprings. These results suggest that the MC extract does not change the photoperiodic influence on reproductive activity of male golden hamsters.

  • This study was carried out to find a cholesterol removal rate, flavor development and bitter amino acid productions in Cheddar cheese treated with $\beta$-cyclodextrin (CD): 1) Control (no homogenization, no $\beta$-CD), and 2) Milk treatment (1000 psi milk homogenization, 1% $\beta$-CD). The cholesterol removal of the cheese was 79.3%. The production of short-chain free fatty acids (FFA) increased with a ripening time in both control and milk treated cheese. The releasing quantity of short-chain FFA was higher in milk treated cheese than control at 5 and 7 mo ripening. Not much difference was found in neutral volatile compound production between samples. In bitter-tasted amino acids, milk treatment group produced much higher than control. In sensory analysis, texture score of control Cheddar cheese significantly increased with ripening time, however, that in cholesterol-reduced cheese decreased dramatically. Our results indicated that the cheese made by $\beta$-CD treated milk with low pressure homogenization showed an effective cholesterol reduction and a rapid cheese ripening, while no capture of flavor compounds by $\beta$-CD.

  • Objective : This research was performed In order to establish the standard of the proper and taste in Korean Medicine. Methods : The change of the proper and taste of Mahwang(麻黃), Gyeji(桂枝), Jagyak(芍藥) and the change of the interpretation of the effect was investigated literally. Results : The hypotheses could be induced as follows. The pungent taste of Mahwang(麻黃) and the sweet taste of Gyeji(桂枝) was inserted by Bonchogyeongso(本草經疏) in Ming Dynasty. In case of Jagyak(芍藥), the proper and taste was changed into sour and cold at Myeonguibyeollok(名醫別錄). It can be proposed that bitter, warm of Mahwang(麻黃), the pungent and warm of Gyeji(桂枝) and the bitter and neutral of Jagyak(芍藥) in Sinnongbonchogyeong(神農本草經) is the adequate proper and taste Conclusions : Therefore it can be hypothesized that the taste and property of Sinnongbonchogyeong(神農本草經) can be established as the standard of the taste and property of Korean Medicine. But in the case of Baekduong(白頭翁), there is the fault of transcribing. So the caution is needed to decide the adequate taste and property.

  • 인삼차의 관능적 향미의 성질을 밝히고져 백미삼(白尾蓼)과 홍미삼(紅尾蓼)에서 얻어진 농축 추출액에 당(糖)을 혼합시켜 제조한 백삼차와 홍삼차를 마실 때의 온도와 설탕의 첨가가 향미에 미치는 영향을 조사하였다. 인삼차의 향미를 표현하는 12가지의 묘사를 선택한 뒤 QDA방법에 의하여 백삼차와 홍삼차를 비교한 결과 백삼차는 흙냄새, 마른나무냄새, 아린맛. 쓴맛등이 강하여 전반적인 향미가 홍삼차보다 강함을 보여 주었다. 온도가 증가하면서 냄새는 전반적으로 현저한 증가를 보인 반면 맛은 쓴맛과 아린맛의 증가외에 뚜렷한 변화의 경향을 보여주지 않았다. 한편, 마실 때의 설탕의 첨가는 냄새에 큰 영향이 없었으나 쓴맛, 아린맛. 떫은맛등 전반적인 맛의 감소를 나타내었다.
