        pH, 有機酸, 아스코르빈酸 및 紫外線照射가 人蔘褐變促進에 미치는 影響

        金相達,都在浩,吳勳一 한국응용생명화학회 1982 Applied Biological Chemistry (Appl Biol Chem) Vol.25 No.4

        pH, 有機酸, ascorbic acid 및 紫外線照射가 紅蔘褐色化反應促進에 미치는 影響을 調査하였다. 紅蔘의 褐色化反應은 弱 alkali性 範圍에서 褐變이 促進되는 傾向을 보였으며 citric acid, succinic acid, tartaric acid等의 有機酸 添加도 紅蔘의 褐變反應을 促進하였다. Fumalic acid의 單獨添加는 紅蔘의 褐色化反應을 促進하였으나 glucose, glutamic acid , glucose+glutamic acid의 混合處理는 褐變을 低下시켰다. 0.1M 以上의 ascorbic acid 處理는 紅蔘褐色化反應에 아주 큰 促進效果가 있었으며 同時에 良質紅蔘의 特有한 色相인 紅色度도 크게 增大되었다. 紫外線照射는 紅蔘乾燥 初期에는 褐變을 상당히 促進하였으나 그 以後에는 褐色度가 滅少되었다. Effects of pH, organic acides and UV irradiation on the browning of ginseng were investigated. Browning of ginseng tended to increase slightly in the alkaline pH range, whereas no discernible pH effect was observed in the pH ranges of 3.0-5.0 and 10.0-12.5. The treatment of fresh ginseng with organic acid such as citric acid, succinic acid, and tartaric acid greatly enhanced the browning reaction of ginseng but all treatments of mixture of glucose, glutamic acid, and glucose+glutamic acid with fumaric acid decreased the browning reaction except the treatment of fumaric acid only. The addition of ascorbic acid in concentration of greater than 0.1 M markedly accelerated the browning reaction and concurrently increased the red color, a characteristic color of quality red ginseng. Irradiation of ultraviolet light while drying red ginseng increased the brown color intensity in the first 5 day·s and thereafter decreased the brown color intensity.

      • 纖維素分解酵素에 關한 硏究 (第 1 報) : Cellulase 生成菌의 分離 및 酵素의 諸性質 Isolation of Cellulase Forming Molds and the Propeties of the Crude Enzymes

        金相達 대구보건대학 1977 대구보건대학 論文集 Vol.3 No.-

        Some 150 cellulase producing strains were isolated from feces of herbivorous animal, soil of farm. Among them, the strain B-7, G-56 were found to be highly active in the degradation of Carboxy Methyl Cellulose. The propeties of their cellulase which was obtained from wheat bran culture were investigated. 1) As a result of observation by microscope, G-56 strain was decided Penicillum and B-7 strain was Aspergillus. 2) Optimal reacting condtion of these cellulase were G56 strain ; PH 3.0, temperature 50℃ B-7 strain;PH3.5, temperature 40℃ 3) As a result of investigation on their their thermal stability, G -56 strain's cellulase was lost harf part of its activity be heat treatment at 60℃~60min, 70℃-6 min, and B-7 strain's cellulase was lost harf part of its activity by heat treatment at 60℃-30 min. 70℃ C-5 min. 4) B-7 strain's cellulase was very stable in the range of PH3.5~6.0, and G-56 strains' was stable in PH 3.0~5.0.

        糖, 아미노酸 및 無機窒素化合物이 人蔘褐變促進에 미치는 影響

        都在浩,金相達,吳勳一,洪淳根 한국응용생명화학회 1982 Applied Biological Chemistry (Appl Biol Chem) Vol.25 No.3

        紅蔘褐變의 適合한 促進方法을 究明하기 위하여 人蔘에 糖, amino酸 및 無機窒素化合物을 處理한 結果 糖類中에서는 maltose와 glucose가 가장 强한 褐變促進作用을 나타내었다. amino酸은 basic amino acid인 lysine, histidine, arginine이 가장 크게 促進했으며 糖과 amino酸 混合處理에서는 glucose와 glutamic acid 退合處理區가 가장 크게 促進되었다. Glucose 濃度別 處理時의 褐變促進效果는 glucose濃度가 增加함에 따라 褐變이 促進되었으며 無機窒素化合物中에서는 urea>(NH₄)₂)HCO₃>COONH₄등의 順으로 褐變이 促進되었다. In order to find out pertinent methods for the acceleration of browing during ginseng processing, various treatments were made or fresh ginseng (Panax Ginseng C.A. Meyer) with sugars, amino acids and inorganic nitrogenous compounds and the extent of browning was measured. Among sugars tested, maltose resulted in the greatest acceleration of browning followed in decreasing order by glucose and lactose, whereas pentoses, fructose, sucrose and raffinose had negligible effect. A marked browning occurred in ginseng treated with basic amino acids, while the extent of browning was not greatly increased when ginseng was treated with aliphatic amino acids, hydroxy amino acids, or acidic amino acids used in the experiment. Among treatments with sugar-amino acid mixture, a mixture of glucose with glutamic acid gave the greatest acceleration. The brown color intensity gradually increased with an increase in glucose concentration for up to 0.5M. inorganic nitrogenous compounds enhanced the browning in general, and the effect varied greatly with the different compounds.

        平面式 太陽熱集熱機를 利用한 紅蔘乾燥

        張奎燮,金相達,洪淳根,尹漢敎 한국응용생명화학회 1982 Applied Biological Chemistry (Appl Biol Chem) Vol.25 No.3

        密閉式물 交換太陽 熱集熱乾燥製置를 利用하여 紅蔘을 乾燥할때의 集熱效率, 乾燥效率. 乾燥特性 및 製品의 品質을 各各 調査하였다. 乾燥其間은 太陽熱集熱製置를 利用한 것이 慣行法보다 3分의 1程度를 더 短 할 수 있었다. 乾燥其間中集熱機의 最大效率은 14.42% 最低效率은 4.73%였고 乾燥效率은 集熱製置를 利用한 것이 28.34%, 對照區가 13.45%로서 純粹乾燥效率은 14.89%이었다. 紅蔘의 乾燥率曲線은 減率乾燥期만을 나타내었으며, 이 때의 式은 Y=50.7023t.-014138 이었다. 乾燥紅蔘의 色度는 慣行法과 比較하여 더 높았으며, diphenylpicryl hydrazyl 遇元能도 같은 傾向을 보였다. A closed solar collector drying system by water exchange was evaluated for the drying of ginseng. The thermal efficiency of solar collector, drying efficiency, drying characteristics and product quality were investigated. The drying period was reduced by one-thirds in comparison with typical method. The maximum and minimum thermal efficiency of the solar collector during drying period were 14.42%, and 4.73%, respectively. The drying efficiency of solar collector and control system showed 28.34%, and 13.45%, respectively: net drying efficiency being 14.8%. The drying rate curve of red ginseng showed only falling rate period, and its equation was Y=50.7023t.^(-0.4138) The brown color intensity of red ginseng was higher in solar collector drying system than in typical method, and reductivity by diphenyl picryl hydrazil solution in red ginseng extract showed similar result to brown color intensity.
