Hydrothermal extraction from dates was done, and then 3 groups of the date extract liquid group (A), the date puree group (B) and the jujube skin flesh group (C) were prepared. And, the omija extract liquid was added to the 3 groups at respective rates of 3:7, 5:5 and 7:3. Then, total 9 medicated diet sources were prepared by adding cinnamon, the ginger extract liquid, honey and pectin. And their physicochenmical and sensory attributes were examined. Total sugar, free sugar and pH increased in the samples of the 3 groups as the addition amount of the jujube extract increased. In chromaticity of respective samples, the "L" value did not show any difference among the 3 groups, but the "a" value was the highest in the "A"group, and "b"value was the highest in the "B"group. In the date puree group and the jujube skin flesh group, their viscosity increased as the addition amount of the jujube extract increased, but in the jujube extract liquid group, no difference was found in its viscosity. As a result of conducting the discrimination test, it was identified that the as the addition amount of the jujube extract was increased, color and sweet taste were feltto be stronger and our taste was felt to be weaker in all 3 groups. In the jujube puree group and the jujube skin flesh group, as the addition amount of the jujube extract increased, the jujube fragrance was felt to be stronger, but in the jujube extract liquid group, no difference was found in its fragrance. And, no difference was found in brightness and viscosity between samples. As a result of conducting the palatability test, no difference was showed in the appearance, but as for the overall palatability including texture, taste and fragrance, preference increased as the addition amount of the jujube extract increased.

In order to increase the antioxidant effect and preference of jujube-omija herbal sauce, we added ethanol extracts of 12 kinds of food and 12 kinds of medicinal herb to the sauce, and then evaluated the antioxidant activity and sensory characteristics. The antioxidant activity of the jujube-omija herbal sauces was greatly increased by the addition of ethanol extracts of foods such as green tea, mugwort, mint, lemon, leek, etc. and those of medicinal herbs such as ginseng. pine needle, the root of arrowroot, orange peel, etc.. Due to the high content of phenolic compounds, the ethanol extracts foods and medicinal herbs appeared to be responsible for high electron-donating ability and low hydroperoxide productivity. While the jujube-omija sauce with the extracts of green tea, mugwort, ginseng and pine needle were not preferred by the panels due to bitter taste and aroma, those of lemon, fruit of Chinese quince, orange peel, etc. were preferred with their sweet and a little sour taste and showed a high antioxidant activity. Especially, lemon juice was the best to increase the antioxidant activity and the preference of the jujube-omija herbal sauce.

The purpose of this research was to develop the apple dressing sauce added pine mushroom (Tricholoma matsutake Sing.) and chitosan which has excellent functionality and scent. An apple dressing sauce with pine added to it was manufactured and tested for sensuality and also for quality changes during storage. The sensory test of the sauces added pine mushroom, the apple dressing sauce added pine mushroom and the apple dressing added pine mushroom and chitosan scored high points. The chromaticity of the apple dressing sauce with pine mushroom compared to the pine didn't show much difference in the L, a, b values and also in the sauces added pine and chitosan, the apple dressing showed less change. At $4^{\circ}C$ and 25, the viscosity of the sauces with pine mushroom showed a small increase in all samples as the storage duration went on. At $4^{\circ}C$, a continuous decrease of the pH was seen in all of the apple dressing sauce added with pine mushroom on storages and from 30 days the pH seemed to start increasing slightly. During storage, the titratable acidity in all samples of the apple dressing with pine mushroom at $4^{\circ}C$ and $25^{\cird}C$ seemed to some what increase as the term went on but there was no significant differences to the acidity. At $4^{\circ}C$, the total viable cells in the apple dressing with pine mushroom showed $1.7{\times}10^{2}CFU/g$ which was the lowest in the beginning of storage period but as the storage period grew longer the total viable cells increased in all of the samples.
