  • Even though plum is well known as a health food, the available processed food of it is quite limited. Furthermore it is difficult to find an easy processing method for leading to a value added product at farmhouse. This study was investigated to effects of temperature for plum extract juice by osmosis of yellow sugar. The plum was mixed with yellow sugar at equal ratio(w/w) to obtain yellowish extracted plum juice and then located in incubator at 15, 25, 35$^{\circ}C$, respectively. The sugar content of extract was high at the early period but decreased throughout extraction period and it was about 66.1~67.4$^{\circ}$Brix. The color difference was increased yellowish throughout the extract period. The pH of it was decreased throughout extract processing but citric acid content was increased. The speed of extraction during extraction processing was more rapid at 15$^{\circ}C$ than 3$0^{\circ}C$. However sensory evaluation score of taste and flavour was obtained at 15$^{\circ}C$ than 3$0^{\circ}C$, so the prefer temperature for plum extract juice by osmosis of yellowish sugar was 15~2$0^{\circ}C$.

  • The primary objective of this study was to determine the optimal mixing ratio in preparing Omi-Galsu concentrate. By varying the amounts of Omija extract, mung bean juice, and sugar in the concentrate mixture, we found that pH increased with greater amounts of Omija extract and sugar. According to sensory evaluations, sugar and total free sugar contents were highest when the mixing ratio was 1:1:20%(Omija extract, mung bean juice, and sugar respectively). This ratio also presented the most attractive color and highest overall acceptability.

  • The effect of concentration of yeast extract and NH4Cl in the mediun of alcohol fermentation of S. cerevisiae ATCC 24858 on the fermentation characteristics, specific growth rate, sugar conversion, alcohol productivity was experimentally investigated. Regardless of initial sugar concentrations, the values of the above three characteristics increased with augument of concentration of yeast extract. However, the increasing tendency ceased above a certain concentration. The concentration of NH4Cl had little effect on the change of the three characteristics. The functional relationships between the concentration of yeast extract and the characteristics were different according to the initial sugar concentrations, but those between the ratio of yeast extract concentration to initial sugar concentration and the characteristics could be expressed as same forms respectively regardless of initial sugar concentrations. Also the values of the three characteristics approached to the maximum values around 0.085 of the ratio, but did not increase any more above 0.1 of the ratio. We have come to conclusion that the optimum ratio of the yeast extract concentration to the initial sugar concentration was about 0.085 and the ratio should not be decided as greater than 0.1 in the medium of alcohol fermentation of S. cerevisiae ATCC 24858.

  • To evaluate the effect of Hydrangea serrata Seringe extract on kakdoogi(Korean radish kimchi), the kakdoogi was prepared, after supplementation, with Hydrangea serrata Seringe extract(0, 1.25, 2.5 and 5%(v/w)). The quality characteristics of the kakdoogi were investigated during 7 days of fermentation at $20^{\circ}C$. The proximate components of the Hydrangea serrata Seringe leaves were 3.48% crude protein, 6.45% crude lipid, 7.98% crude fiber and 9.32% crude ash. The pH values in the samples with the extract were higher than that of both the control group and the sugar group. The total acidity levels in the sugar group was higher than that of other groups. The sugar group showed higher L value(lightness) than that of kakdoogi fermented with the extract. A value(redness) and B value(yellowness) of the supplemented kakdoogi was lower than that of the control and the sugar group on day 7. The hardness of samples with the extract was higher than that of the sugar group. And the hardness of the groups with the extract was not reduced during the fermentation period. The control group showed higher salinity than the other groups by day 4. The samples with the extract were sweeter than the control group on day 0 then the difference disappeared after day 2. Sourness of all the groups increased during the fermentation period. However the extract did not affect the hardness or overall acceptability of the kakdoogi during fermentation.

  • This study was aimed to investigate the effects of Ginseng ethanol extract on Diabetes induced by alloxan in comparison with that of insulin. The blood sugar, blood urea nitrogen, glutamic oxaloacetic transaminase and cholesterol were measured by spectrophotometry. The results were obtained as follows. 1. Ethanol extract of Ginseng increased the blood sugar level in normal rats. 2. Ethanol extract of Ginseng restrained the increase of blood sugar in diabetes induced by alloxan. 3. Ethanol extract of Ginseng acted to oppose a rapid decrease of blood sugar by insulin. 4. Blood urea nitrogen, glutamic oxaloacetic transaminase and cholesterol level in blood were not affected by Ginseng.

  • Response surface methodology (RSM) was used for analyzing the manufacturing process of Prunus mume extract-added vinegared red pepper paste (maesil chokochujang) with respect to sensory quality properties. Experiments were carried out according to a central composite design, selecting the amount of kochujang, amount of maesil extract, and type of sugar in the mixture as independent variables; sensory attributes such as flavor, taste, color, and mouthfeel viscosity as response variables. The polynomial models developed by RSM for sensory color and mouthfeel viscosity were highly effective to describe the relationships between the factors studied and the responses. The estimated response surfaces confirmed that the amount of kochujang had a positive effect on color (p<0.001) whereas the amount of maesil extract had a positive effect on mouthfeel viscosity (p<0.001). Increase in the amount of kochujang led to a sharp increase of the sensory score on color at all the maesil extract and sugar type levels. On the other hand, increase in the amount of maesil extract caused a sharp increase in the mouthfeel viscosity value regardless of kochujang concentration and type of sugar. The differences among samples made with different types of sugar were not significant (p>0.05).

  • Effects of water extracts of antler on blood sugar levels were studied in normal rats and KK-mice. a spontaneously diabetic strain of murine. Blood sugar levels were determined at 30, 60, and 120 minutes after intraperitoneal administration of 1 ml/kg or 2ml/kg AE into normal rats. A moderate but significant decrease in blood sugar level was noticed only in 30 minutes following 2 ml/kg AE administration. On the other hand no significant changes in blood sugar level was observed in KK-mice to which 1ml/kg/day AE had been given for 10 weeks. The results of present study strongly indicate that antler extract exerts no significant effect on blood sugar levels in experimental animals.
