  • This study was conducted to promote the utilization of fish paste with 0, 2, 3, and 4% added Curcuma aromatica powder. The moisture, crude protein, crude lipid, and crude ash contents of the used Curcuma aromatica powder were 11.15, 6.25, 2.36, and 9.98%, respectively. For the Hunter color values, the L, a values of the fish paste decreased with increasing concentrations of Curcuma aromatica powder, while the b values appreciated. In the folding test, whose results reveal the flexibility of the fish paste, all the test samples showed AA results. In the texture meter test, the hardness, cohesiveness, and springiness increased with increasing concentrations of Curcuma aromatica powder, but the gumminess and brittleness of the fish paste were reduced. In the sensory evaluation, the color and taste of the fish paste with 3% added Curcuma aromatica powder were preferred over those of the other fish pastes. These results suggest that Curcuma aromatica powder can be applied to fish paste to achieve high quality and functionality.

  • Ripened Rubus coreanus Miquel harvested at Gochang was stored for 8 months at $-20{\pm}2^{\circ}C$, and quality changes were investigated at intervals of 2-3 months. Soluble solid concentration increased slightly, but acidity fell during frozen storage. The lightness (L value) and red color index (a value) of ripened R. coreanus Miquel decreased during storage. The vitamin C and ellagic acid contents were 30.79 mg/100 g and $155.12\;{\mu}g/100\;mg$ mg before storage, respectively, but fell to 17.03 mg/100g and $140.11\;{\mu}g/100\;mg$ after 8 months of storage. However, the total anthocyanin content was 39.45 mg/100 g before storage, and this remained unchanged from 2 to 8 months of storage.

  • The objective of the present study was to investigate differences in quality of kimchi products produced in Korea, Japan, and China. Kimchi products from kimchi-producing countries with high consumer consumption such as Japan and China along with local products from Korea, where exporting has not yet started, were collected. Product pH, acidity, salinity, package pressure, gas production were assessed, and microbiological analyses and sensory evaluations were performed on kimchi products that were stored at either $4^{\circ}C$ for 63 d or $15^{\circ}C$ for 20 d. The pH and acidity results showed that as Japanese and Chinese kimchi had higher pH and lower acidity than that of Korean kimchi, which was determined to be indicative of insufficient microbial fermentation following kimchi production. Japanese kimchi had different microbial properties than those of Korean kimchi, which is due to differences in their manufacturing processes. Overall preferences derived from sensory evaluations were: Korean kimchi>Chinese kimchi>Japanese kimchi. The results of this study demonstrate the sensory superiority of Korean kimchi and may be useful when predicting consumers' acceptance level of Korean kimchi exported to other countries.

  • This study was performed to examine the quality and antioxidant activity of pork ham with various levels of black garlic extracts. Pork ham manufactured from black garlic extracts with 15 brix (1% (H1), 1.5% (H2), 2% (H3)) and 30 brix (0.2% (H4), 0.5% (H5), 1% (H6) were stored for 28 days at $8{\pm}1^{\circ}C$ and analyzed with an interval of 7 days. In the sensory evaluation, the garlic odor was increased as the garlic extract adding level larger, whereas color, flavor, juiciness, texture and acceptability were not showed significant differences. The pH values of pork products were increased as the level of black garlic extracts increased. The shear force value of groups (H4~H6) with the addition of 30 brix extracts addition were significantly higher than those groups with 15 brix extracts addition (H1~H3) throughout the storage period. Furthermore, the TBARS (thiobarbutric acid reactive substance) content of the pork ham containing various levels of black garlic extract were lower than that of the control group as storage period increased. Thus, black garlic extracts have a potential application for the pork products to inhibit of lipid oxidation.

  • The purpose of this research is to develop bellflower (Platycodon grandiforum) root Jeonggwa as a health food. The Omija (Schizandra chinensis Baillon) water extract with 0-8% (w/w) Jeonggwa added was stored at $25^{\circ}C$ for 12 weeks. The quality characteristics of Jeonggwa during storage were investigated. The Jeonggwa showed a lower pH and a higher acdity as the amount of Omija water extract that was added increased. The moisture content of Jeonggwa were rose from 15-18% to 16-22% within 2 weeks of storage, and remained at that level up to the end of storage. The total viable cells of bellflower root Jeonggwa were 2.1~2.3 log CFU/g and increased in number during storage but never exceeded 4 log CFU/g. The shelf life of the Jeonggwa was extended when the Omija extract was added. The lightness (L), redness (a) and yellowness (b) of the Jeonggwa during its storage at $25^{\circ}C$ were highest in control samples, and the values decreased with the increase in the Omija extract concentration (p<0.001). The mechanical evaluation of the Jeonggwa showed that various tested parameters fell during the storage at $25^{\circ}C$. The hardness and strength of the Jeonggwa significantly decreased as the Omija extract concentration rose (p<0.05). In the ensory evaluation tests, the acceptability of the Jeonggwa was optimal when 4~6% of Omija extract was added to it.

  • We investigated the effect of grape-must temperature ($50^{\circ}C$, $60^{\circ}C$, and $70^{\circ}C$) on wine quality. We used Muscat Bailey A (MBA) grapes; these are often used in wine making in Korea. The numbers of viable bacteria, yeasts and molds in grape-must decreased with an increase in temperature. Polyphenol oxidase activities in grape-must were reduced at high temperatures. Redness; and, total anthocyanin, polyphenol, and tannin contents of MBA grape wine were higher after heating at $70^{\circ}C$ than after use of lower temperatures. Antioxidant activity was also enhanced after exposure to high temperatures, which may be attributable to the presence of increased levels of polyphenolic compounds in the grape-must. Thus, the heat treatment to prepare grape-must before wine fermentation greatly affects wine quality.

  • We investigated changes in quality during storage of cookies prepared with pine needle powder these are functional foods. We chose the quantity of pine needle powder (0%, 3%, 6%, or 9%, by weight) and storage time (1 day, 3 days, or 5 days) as independent variables and conducted sensory tests, measured chromaticity, and investigated physical properties. Differences in sweetness (p<0.05), bitterness and overall preference (both p<0.001), were noted on sensory testing, and were all significant. The degrees of brightness (p<0.001), redness (p<0.001), yellowness (p<0.001), and hardness (p<0.05) increased significantly as pine needle powder content increased, and changes in brightness and redness (both p<0.01) during storage were also significant.
