Recipe for Korean typical wild.vegetable preparations were developed and changes in pH, total acidity and ascorbic acid were measured during the storage period at 4~$5^{\circ}C$. Crude fiber and minerals were also analyzed and sensory evaluation was conducted. Changes in pH and total acidity were not significant in most of the samples and the results reveal that the vegetable preparations were in good conditions throughtout the storage period at 4~$5^{\circ}C$. The contents of ascorbic acid have been gradually reduced during the first 10-day storage showing 30~70% retention and continuous loss to 30~40% left on 20th-day. Crude fiber and mineral (Ca, p, Fe, K, Mg) contents were relatively higher in the wild-vegetables than in the everyday use vegetables. The results of the sensory evaluations revealed that the tested samples were in good scores (overall scores>6) except sancho-seed pickles.

The purpose of this research was to investigate the property of sensibility of silk fabrics by the linen-like finishing-used polyurethane resin. Subjective evaluations of preference and related sensory descriptors were estimated. Also, related physical and psychological variables were measured. And their correlations were investigated. The value of EM, WT, WC, MIU, and qmax of silk fabrics treated with polyurethane resin decreased and LT, B, 2HB, G, 2HG, 2HG5, and SMD increased. Physical variables which affected on the preference of summer fabrics are B, 2HB, G, 2HG5, qmax, MIU and LT. It was confirmed that silk fabrics treated with polyurethane resin were preferred as a summer fabric. Individual sensibilities that had effects on the preference of summer fabrics were softness including rough and cold. The intensities of weight value on sensory descriptors, which were related with the preference in summer environments, were in following orders: cold, rough, slippery, flexible, stiff and damp. There was no relationship between the subjective evaluation of preference and related sensory descriptors on the fabric and comfort sensation of fabric was derived from psychological variables

This study was performed to determine the optimal manufacturing conditions adding green laver, which has a rich aroma and unique taste, to Sulgidduk. The variables in green laver Sulgidduk production were amounts of green laver powder and water. Six sensory characteristics were used for sensory evaluations, including color, green laver flavor, green laver taste, moistness, softness, and elasticity. The optimal amounts of the powder and water were found to be 6.84 g for green laver powder and 31.08 g for water, satisfying a target sensory score (7.0/9.0) according to a response surface method. Sulgidduk with these optimal amounts of green laver and water was tasted by 118 consumers and showed a high acceptability score (6.94). Older consumers ($\geq$30 years old) preferred the color and flavor of green laver significantly more than younger consumers ($\leq$29 years old) did (p<0.01). Color analysis results of green laver Sulgidduk were significantly different in brightness, redness, and yellowness from those of Sulgidduk (control)(p<0.01). Texture analysis scores of green laver Sulgidduk were significantly lower than those of Sulgidduk (control) in hardness, adhesiveness, springiness, cohesiveness, gumminess, and chewiness, and they were significantly different in adhesiveness and chewiness (p<0.05).

This study was performed to examine the quality characteristics of red ginseng wet noodles prepared with additions of carrageenan, xanthan gum, or guar gum. The quality characteristics of the samples were estimated in terms of their general composition, color differences, cooking characteristics, textural attributes, sensory qualities, and microbial growth during storage. The results were as follows. Protein content was significantly decreased in the guar gum added group and ash content was significantly increased in the carrageenan added group (p<0.05). Lipid, water, and Na contents were not significant different among the groups. However, water binding capacity was significantly increased in the group with added xanthan gum. Over 10 weeks of storage, water contents did not differ significantly between the xanthan gum and guar gum added groups. In all the added gum groups, L- and a- values were significantly increased whereas b- values decreased (p<0.05). In texture profile analyses, chewiness, cohesiveness, hardness, and springiness were significantly increased in the carrageenan and xanthan gum added groups (p<0.05). According to sensory evaluations, surface color, red ginseng flavor, red ginseng taste, softness, chewiness, and overall acceptability were considered very good in the xanthan gum and guar gum added groups (p<0.05). Therefore, the red ginseng noodles containing xanthan gum and guar gum were deemed most preferable and presented the safest shelf-life during 10 weeks at -$10^{\circ}C$.

This study was designed to establish the stability of EGHB010, a combined hot water extract of Paeoniae Radix and Glycyrrhizae Radix. Test of coliform groups, sensory evaluations, contents of moisture, and the amount of paeoniflorin and glycyrrhizin were determined during storage at 4, 25 and 35℃ for 6 months. Coliform groups were not observed and moisture contents were maintained about 3.0% during the storage period. Sensory characteristics including color, taste, texture and appearance were tested over 3 points throughout the entire storage period. It maintained the commercial value during the storage period. Contents of paeoniflorin and glycyrrhizin as indicator components were remained stably for the storage period. The shelf-life of EGHB010 based on a linear response to zero of sensory evaluation with the highest correlation coefficient was predicted. Finally, the shelf-life of EGHB010 was expected for about 3 years to consider in safety coefficient. The shelf-life data of EGHB010 can be used to develop a functional health ingredient.
