  • Kimchi vacuum packaged in PET/AI/PE pouch was stored at $0^{\circ}C\;and\;10^{\circ}C$ to evaluate the effect of vacuumizing conditions on quality changes. The quality of kimchi during storage was investigated in terms of pH, titratable acidity, color, viable counts of lactic acid bacteria including Leuconostoc and Lactobacilli and sensory properties. Titratable acidity and pH were not significantly different for the vacuum degrees. Color index (L b/a) values of crushed kimchi juice decreased exponentially and remained constant during storage, but the resulting color change was not affected by the vacuum degrees. Viable counts of lactic acid bacteria and sensory scores exhibited no significant difference among the kimchi of different vacuum degrees. Consequently, the vacuum degree in packaging of kimchi seemed to influence little on quality of kimchi. For enhancing the commercial value of vacuum packaged kimchi products, it would be appropriate to produce a slight vacuum, eliminating the head space, within packages.

  • This study was conducted to promote fish paste made with white poria cocos wolf powder as a food. The tested concentrations of the powder were 0, 1, 3, 5, and 7%. All the fish paste samples had 37% water content. For the Hunter color values of samples, L-values decreased but a- and b-values increased with increasing concentrations of the powder. In addition, the folding test scores of all samples were good (AA). In the texture tests, brittleness increased where as springiness decreased with increasing concentrations of the powder. In the sensory evaluations, color, flavor, hardness, and cohesiveness scores increased, and sleekness and oily taste scores decreased, with increasing concentrations of the powder. The fish paste containing 3% white poria cocos wolf powder (3WPWP) had the highest acceptance scores for appearance, flavor, taste, texture, and overall quality. These results suggest that white poria cocos wolf powder can be applied to fish paste to increase its quality.

  • Physicochemical and sensory characteristics of turnip pickles added with chitosan and/or beet water extract were investigated. Turnip root slices (4${\times}$1${\times}$0.5 cm) were salted with NaCl and CaCl$_2$, soaked into pickling solution, and then stored at 2$0^{\circ}C$. Throughout the whole storage periods, pH, acidity, saltiness and soluble solid content of three pickles (C, turnip pickle; CC, turnip pickle+chitosan; CBC, turnip pickle+chitosan+beet water extract) ranged to 3.1 ∼ 3.5, 1.5 ∼ 1.7%, 0.5 ∼ 0.7% and 24.5 ∼ 28.5$^{\circ}$Brix, respectively. There were no significant differences between three pickles in saltiness, anthocyanin and reducing sugar content. However, acidity and hardness of CC and CBC were higher than those of control C throughout the storage time. While Hunter's a value of CBC was higher than those of CC or C. Sensory results showed that the best edible time was the 14th day of storage, and at that time, scores of CC and CBC were higher in over-all preference (7.8 and 8.4) than those of C (6.1), and CC and CBC maintained good sensory qualities until 28th day of storage, compared to C (p<0.05).
