The purpose of this study is to find out the optimal mixing ratios of three different amount of red ginseng powder(0, 5, 10%), water(12, 16, 20%) and sugar(4, 8, 12%) per weight of glutinous rice powder. The microbial count increased with increasing moisture content. The microbial count has decreased in 10% addition group though the microbial count according to the red ginseng powder addition did not have a difference the having mind in 5% addition group. Control group(the red ginseng powder no addition) showed an exponential increase in the change in hardness according to the amount of the red ginseng powder addition 24 hours after(except the moisture addition amount 20%). However, the change in devotion hardly appeared without the relation in moisture and the amount of the sugar addition in the addition group of the red ginseng powder 5%. Moreover, the change in hardness besides the moisture addition amount 12% hardly appeared also in the addition group of the red ginseng powder 10%. It has been understood that the red ginseng powder addition 5% crowd smells, and the taste and the color are suitable though it was clarified to the red ginseng powder addition 10% crowd that a peculiar smell taste and taste to the red ginseng are very strong by the sensory inspection. In conclusion, according to its microbial count, texture and sensory analyses, the optimal Injulmi formulation consisted of red ginseng powder, water and sugar were 5, 16 and 8%. The results suggested that red ginseng powder is effective in increasing the self life of Injulmi.

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.

This study was conducted to investigate the responses of red pepper (Hongjinju) leaves under water stress. Hyperspectral short wave infrared (SWIR, 1000~1800 nm) reflectance imaging techniques were used to acquire the spectral images for the red pepper leaves with and without water stress. The acquired spectral data were analyzed with a multivariate analysis method of ANOVA (analysis of variance). The ANOVA model suggested that 1449 nm wavebands was the most effective to determine the stress responses of the red pepper leaves exposed to the water deficiency. The waveband of 1449 nm was closely related to the water absorption band. The processed spectral image of 1449 nm could separate the non-stress, moderate stress (-20 kPa), and severe stress (-50 kPa) groups of red pepper leaves distinctively. Results demonstrated that hyperspectral imaging technique can be applied to monitoring the stress responses of red pepper leaves which are an indicator of physiological and biochemical changes under water deficiency.

The amount of irrigation water can be calculated based on the irrigation schedule in irrigation manual. At present, the maximum irrigation manual, which was developed in 1999 for the maximum yield with maxmum irrigation, is using. Now the water saving irrigation manual for red pepper, without decrease of crop yield, has been developded in 45 areas of korea. Among 45 regions, 9 regions which were selected respectively from 9 Provinces of Korea, were used for this study. The water saving irrigation manual has been used easily without soil sampling and measurement of soil water status. The objective of this study is to assess the possibility of the saving of irrigation water compared to the maximum irrigation manual. The average potential evapo-transpiration (PET) during 30 years in 9 region for the red pepper cultivation was a $2.69mm\;day^{-1}$. The saving amount of irrigation water for red pepper cultivation by saving irrigation manual compared to the maximum irrigation manual in a year was 309.4 mm, 303.3 mm and 309.5 mm in the soil of Sandy Loam (SL), Loam (L) and Silty Loam (SiL), respectively. The average saving amount of irrigation water for red pepper cultivation by saving irrigation manual compared to the maximum irrigation manual in a year was 307.4 mm.

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.

This study aimed to investigate the effects of red pepper seed powder on the physicochemical properties (pH, CIE color value, water holding capacity, dry yield, proximate composition, and shear force) of restructured chicken thigh jerky. The restructured chicken thigh jerky samples were prepared with the following amounts of red pepper seed powder [0% (control), 1%, 2%, and 3%]. Moisture contents of samples containing red pepper seed powder were significantly higher than those of control (P<0.05). The lightness, redness, and yellowness of samples an increased with an increase in red pepper seed powder. Water holding capacity and dry yield of samples increased with increasing concentration of red pepper seed powder. However, shear force of samples showed a downward trend with increasing red pepper seed powder level. The sensory evaluation of samples containing 3% red pepper seed powder were highest. The results indicate that red pepper seed powder could be enhance the physicochemical properties of restructured chicken thigh jerky.
