  • 본 연구의 목적은 홍삼 분말(0, 5, 10 %), 물(12, 16, 20 %), 설탕(4, 8, 12 %)의 첨가량을 달리하여 최적의 배합비를 찾기위하여 실시하였다. 인절미 제조에 있어서 수분 첨가량이 증가할수록 생균수는 증가하였다. 홍삼가루 첨가에 따른 생균수는 5% 첨가군에서는 유의적인 차이가 없었지만 10% 첨가군에서는 생균수가 감소하였다. 홍삼 첨가량에 따른 굳기의 변화는 홍삼 무첨가군은 수분첨가량 20%를 제외한 실험군에서 24 hr이후에 급격한 증가를 나타내었다. 그러나 홍삼 5% 첨가군에서는 수분 및 설탕 첨가량에 상관없이 굳기의 변화가 거의 나타나지 않았다. 또한 홍삼 10% 첨가군에서도 수분 첨가량 12% 이외에는 굳기의 변화가 거의 나타나지 않았다. 관능검사에서 홍삼 첨가 10%군은 홍삼 특유의 향미와 맛이 너무 강한 것으로 나타났으나, 홍삼 첨가 5%군은 향, 맛, 색이 적당한 것으로 나타났다. 생균수 측정, 조직감 측정과 관능검사의 결과에서 홍삼인절미의 최적의 배합비는 찹쌀가루에 대해 홍삼가루, 수분, 설탕이 각각 5, 16, 8%로 나타났으며 홍삼가루 첨가는 인절미의 저장성 향상효과가 있었다.

  • Background: A six-week study involving two hundred and fifty (250) Harco Black layer birds at point of lay was conducted to investigate the effects of potential natural colorant on performance and Egg quality traits. The birds were assigned to five (5) dietary treatments, each containing supplements either of control, Baobab Leaf (BL), Waterleaf (WL), Red Pepper (RP), Canthaxanthin (CTX) at 40 g/kg feed and 50 mg/kg feed of natural and commercial colorants, respectively. Results: Performance records shows that there was no significant (p > 0.05) difference in feed intake across the supplements of Red pepper, Water leaf, Canthaxanthin and control diet, however, birds fed Baobab leaf treatment had a significantly lower (p < 0.05) feed intake value (94.07 g) when compared with other treatments. Body weight gain and Hen Day Production were not significant influenced (p > 0.05) by the dietary treatments, although laying hens fed Baobab leaf supplement had lowest mean HDP of 48.80%, while birds fed Red pepper and Water leaf supplement had an average value of 52.79%. There was no significant effect (p > 0.05) of colorants on egg external traits, compared with the control; birds fed Canthaxanthin treatment had higher mean egg weight (51.79 g), egg length (4.55 g), egg breadth (3.29 g); Red pepper treatment had highest mean shell thickness (0.29 g), however these differences were not significant (p > 0.05). Yolk height, Albumen height, Yolk index, and Haugh unit were not significantly affected (p > 0.05) across treatments. Yolk width was lowest (p < 0.05) in Baobab leaf treatment (2.54 cm); Red pepper, Water leaf and Canthaxanthin (2.89 cm, 2.62 cm and 2.89 cm respectively) were not significantly (p > 0.05) different from the control (2.73 cm). Yolk colour score was significantly highest (p < 0.05) in Red pepper treatment (7.50); Water leaf, Baobab leaf and Canthaxanthin ranged between 2.25-3.31 on the DSM yolk colour fan, Control treatment had the lowest yolk colour score (p < 0.05) of 1.31. Conclusion: The study showed Red pepper as a worthy alternative to commercial yolk colorant. Water leaf and baobab are not good substitutes for canthaxanthin as a yolk colourant.

  • 본 연구에서는 고추의 수분스트레스 반응을 최적으로 계측할 수 있는 알고리즘을 개발하기 위해 초분광 단파 적외선 영상기술을 적용하였다. 수분스트레스에 노출된 고춧잎의 단파적외선 분광영상을 획득하고 ANOVA 분석을 이용하여 수분스트레스 반응을 가장 잘 반영하는 파장영역을 선정하였다. 고춧잎의 단파적외선 초분광 영상을 이용하여 ANOVA 분석을 수행한 결과 수분스트레스 판별을 위한 최적 파장은 1449nm으로 물분자의 광흡수 영역대와 거의 일치하였다. 최적 파장에서의 고춧잎 상대반사값을 가우시안 회귀분석을 통해 정상군과 토양흡착수압이 -20kPa과 -50kPa일 때의 스트레스군을 구분할 수 있는 임계값을 계산하고 이 값을 기준으로 단파적외선 영상을 이진화하여 수분스트레스 반응을 판단할 수 있는 최종영상을 구축하였다. 결과 영상에서 정상군과 스트레스군의 토양흡착수압이 -20kPa인 잎의 경우 스트레스 반응을 보인 픽셀이 72%이었고, -50kPa인 잎에서는 스트레스 반응을 보인 픽셀이 84%로 12%차이가 났다. 정상군과 스트레스 강도가 다른 시료의 경우 영상의 결과가 명확히 구분되는 것으로 나타나 단파적외선 영상기술이 고춧잎의 수분스트레스 상태를 정량적으로 나타낼 수 있는 기술임을 확인할 수 있었다.

  • Large scale of fish kills by red tides has been occurred every year in coastal water fisheries of Korea. To suppress red tide spreading out over the south coastal water of the Korean Peninsula large amount of loess has been applied every year because loess is known to be effective in removing red tide organisms. Effects of loess application in ecosystem of underwater near sea shore were investigated with some physical characteristics of loess. Loess used for the red tide reduction consisted of very fine particles, of which size was mostly less than 0.1 mm. Particles of loess blocked light penetration, which is essential for the underwater ecosystem. Loess also pushed pH down by the hydrolysis activities of aluminium and iron It was found that underwater ecosystems where loess was applied near sea shore were devastated. Sea plants such as sea weeds were gone leaving only their roots. Clams and snails were dead under the loess dust blanket. And fishes were not found at all where loess has been sprayed lot long time. It was found that even if loess has some capacity to reduce red tide temporarily, loess application should be slopped to protect underwater ecosystems.

  • This study was designed to examine the effects of red ginseng total saponin and extract on spatial working memory in mice using Morris water maze. Two kinds of red ginseng saponin (No. 1 and No. 2) and three kinds of red ginseng extract (No. 1, No. 2 and No. 3) to have different PD/ PT ratio (No. 1=1.24, No.2=1.47 No.3=2.41) were prepared by mixing the different parts of red ginseng In different ratio. In acute administration of total saponin No. 1 or No. 2, escape time to reach to a hidden platform In a fixed location for training trials was significantly decreased as compared with control group and swimming time in the quadrant that had contained the platform was also significantly increased as compared with control group. In acute treatment of extract No. 1 or 1 No. 2, swimming time in the platformless quadrant was increased dose dependently as compared with control group, especially at dose of 200 mg/kg,bw swimming time was significantly Increased. Oral treatment of extract No. 1 (100 mg/kg, bw) for 7 days produced an increase of swimming time In the platformless quadrant but a decrease of swimming time in No.3-treated group (100 mg/kg, bw). These results show that red ginseng may improve spatial discrimination learning and spatial working memory of mice

  • Browning intensity is a major factor to estimate the quality of red ginseng or red ginseng products. The Maillard type of browning reaction proceeds nonenzymatically during extraction and concentration of red ginseng. The present studies were carried out to investigate the effects of amino acids and sugars on the browning reaction during extraction and concentration of red ginseng. Red ginseng was pulverized to 115 mesh and then tenfold (v/w) of water was added to the powder to make the substrate of red ginseng. Solution (0.1 M) of fourteen amino acids and of folly silgars were added to the substrates of red ginseng powder and these were then extracted and concentrated to examine their browning intensities. Amino acids were more effective than sligars in acrelerating the browning reaction. Acceleration of the browning reaction in the concentrate was in the order of arginine> histidine>glycine>alanine>lysine phenyl alanine>aspartic acid>lelicine>threonine>gllitamic acid>tyrosine>valine>istleucine>methionine for amino acids, and was glucose>frlictose >silcrose, maltose for sugars.

  • A study was designed to study the sorption characteristics of powder-type products of red ginseng such as red ginseng tea, red ginseng powder and spray 4ried powder of red ginseng extract The sorption rates and equilibrium moisture contents on these products were calculated at ova. a range of relative himidities and two different temperatures ($25^{\circ}C$ and 38$^{\circ}C$). Significant differences between these three products were found in water activities, sorption rates and the relationship between the ratio of %H2O/RH and moisture content The red ginseng tea required the most excessive drying to reach aw=0.4, followed by red ginseng power and spray dried powder of red ginseng extract Attempt was made to obtain equations which can predict sorption rate and moisture content of red ginseng products at given relative humidity and temperature after certain period of storage.

  • To carry out baseline studies on monitoring systems for red tides in Jinhae bay, measurements and analyses were made on seawater samples from 15 sampling stations during 15 months from July, 1979. Water quality parameters studied are temperature, pH, DO, salinity, COD, SS, NO$\sub$3/, NO$\sub$2/, PO$\sub$4/, SiO$\sub$2/, Ca, Mg, Cd, Cu, Pb, Zn, Chlorophyll ${\alpha}$, diatoms and dinoflagellates. Multiple regression analyses were undertaken with chlorophyll ${\alpha}$, cell numbers of diatoms and dinoflagellates as the dependent variables and water quality parameters as the independent variables. The results showed that biomass, expressed as total cell numbers of diatoms and dinoflagellates, was largely influenced by COD, salinity and nutrients.
