This study was conducted to investigate the quality characteristics of the bread with red ginseng powder(RG). Four different powder concentration levels of 0, 3, 6, and $9\%$ were added to flour to make the bread. The appearance, pH, water holding capacity, specific volume, color, texture, and sensory properties were analyzed. pH of bread with RG had no difference according to the content of the red ginseng powder. The specific volume of the bread containing $0,\;3,\;6\%$ were bigger than that of the bread with $RG-9\%$. The water holding capacity of the bread with $RG-9\%$ was the highest. As the amounts of RG increased, L-values of the bread crumb were decreased and a- and b-values were increased. As a result of texture measuring by texture analyzer, hardness and gumminess were not affected by the addition of RG. Also, springiness, cohesiveness, and chewiness were not significantly different among the control, $RG-3\%\;and\;RG-9\%$. In sensory evaluation, color, flavor, taste and overall acceptability in the bread with $RG-9\%$ were significantly lower than the control and the other groups. On the other hand, the best result for sensory characteristics showed when red ginseng powder at $3\%$ level was added to the bread.

Immature and mature plums(Prunus salicina L.) were coated with calcium-added methylcellulose(CaMC) and hydroxypropylmethyl-cellulose-15(CaHPMC-15). Physicochemical, nutritional and sensory characteristics were compared during the 8-day storage period at $30^{\circ}C$. Irrespective of maturity, pH of plums increased and the titratable acidity decreased during storage. Free sugars such as glucose, fructose, sucrose and sorbitol were eventually decreased during storage, but Ca-added cellulose coatings influenced on the prevention of free sugars from decreasing especially in mature plums. Vitamin C contents in immature and mature plums became decreased during storage, but the coatings took effective on its retention. Changes of malic acid, the major organic acid in plums were appeared the same tendency as vitamin C during storage. Results of sensory evaluation showed the development of red color in peel and the softening of plum tissue, and also showed that the overall eating quality and appearance generally decreased during storage. However, the coated plums either CaMC or CaHPMC-15 exhibited the better sensory characteristics. As though the significant difference in postharvest storage quality were not found between the two coatings, CaMC and CaHPMC-15 coatings significantly contributed to the improvement of overall storage quality, especially the retention of vitamin C and organic acids only on the mature plums.
