  • This study was performed to improve the availability of reed and quality of traditional Yakju by using roasted reed. The pH of sprout Yakju was 3.43, whereas the pHs of other Yakjus were 3.57. No remarkable differences were observed in contents of total titratable acids and reducing sugars. Color changes were measured by Hunter's color value; L value decreased, whereas redness (+a) and yellowness (+b) increased during fermentation. Ethanol content of Yakjus prepared with sprout and root were 15.30% and 15.28%, respectively, which were lower than that of control Yakju (15.31%). However, there were obvious differences of ethanol contents in three types of Yakjus. The major free sugar and organic acid were glucose and lactic acid, respectively. The total polyphenol contents of sprout Yakju (4.26 mg%) and root Yakju (4.21 mg%) were much higher than that of control Yakju (2.56 mg%). The DPPH (1,1-diphenyl-2-picryl-hydrazyl) free radical scavenging activities of sprout Yakju and root Yakju were higher than those of control Yakju. Yakju prepared from 0.3% addition of sprout showed the highest score in overall preference from the sensory test.

  • The pork quality was determined with following treatments. The meat samples were obtained from pigs which had been fed finishing pig diets containing 5% beef tallow(Control), 3% beef tallow and 2% perillar seed oil(T1), 250 ppm vitamin E(a-tocopheryl acetate) in T1(T2), 3% beef tallow and 2% squid viscera oil(T3), 250 ppm vitamin E in T3(T4), 3% beef tallow and 2% CLA(Conjugated linoleic acid, T5). T1 had the lowest sarcomere length, salt solubility and total protein contents among the treatments. Salt solubility and total protein content of T2 and T4 which had been fed diets containing Vit. E were higher than those of T1 and T3 which had not been fed diets without Vit. E. pH and water holding capacity(WHC) values of control were higher than those of T1, T3 and T5, while WHC of T2 and T4 was higher than those of T1, T3 and T5. The hunter L value of meat and a value of fat showed higher in T5 than those in control, T, T3. The adhesiveness of T3 and the springiness of T5 in cooked meat showed higher level than other treatments.

  • This study was carried out to investigated the quality characteristics of kimchi, made by adding blue crab. Kimchi is made into a fermented vegetable food by adding red pepper powder, garlic, ginger and fermented salted fish to the salted cabbage or radish. Chitin/chitosan, found in the shell of crab is the biopolymer. Chitin possesses many beneficially biological properties. Salt consumption impacts on human health problems such as hypertension and cardiovascular disease. In this study, we hypothesized that kimchi added with raw blue crab would reduce excessive salt consumption and increase protein supplementation. We analyzed lactic acid bacteria level, pH, acidity, salinity and free amino acid of kimchi added with blue crab during 1, 15 and 30 days storage period at $5^{\circ}C$. Lactic acid bacteria, pH, salinity increased significantly in kimchi added with blue crab compared to the control. Accordingly, this result suggested that kimchi should be manufactured by adding raw fish rather than fermented salted fish.

  • This study was carried out to determine the effects of media compositions on cell growth and casein hydrolysis for cell production in order to add Micrococcus sp. LL3 as a potential agent for industrial application for the shortening of ripening period. Monosaccharides like glucose, mannose and fructose were mare excellent as carbon source, but arabinose and xylose markedly inhibited cell growth and caseinolysis. Among the organic nutrients, yeast extract was more effective for cell growth and for caseolysis. However, inorganic nitrogen sources were less effective than organic sources. Urea inhibited cell growth severely. Cell growth and caseinolysis were rather increased a little in the broth containing 1% NaCl, and the organism tolerated and grew in relatively high concentrations of NaCl up to 9%. Addition of vitamin did not affect cell growth and caseolysis in level of $0.1\;{\mu}g/ml$ concentration. Cell growth and caseinolysis were stimulated by addition of glutamic acid and $MgSO_4$ with concentration of 0.2% and 0.05% respectively.

  • Physicochemical properties and palatability of pork patties prepared with 3 levels (1%, 2%, and 4%) of seaweeds, sea mustard, green laver, and seaweed fusiform were studied. The addition of seaweed powders to pork patties increased crude ash content of the patties. When the patties were heated at an internal temperature of $72^{\circ}C$ for 15 min, cooking loss was decreased as the amount of seaweed increased. Also, the addition of sea mustard showed the lowest cooking loss. Volatile basic nitrogen (VBN) of patties stored at $4^{\circ}C$ was lower in patties containing seaweed than in the control patties. Juiciness of the cooked patties was increased in patties with seaweeds, while springiness was decreased. The addition of seaweed did not affect flavor preference and overall acceptance scores in spite of sensing seaweed flavor. In summary, the addition of seaweed in preparation of pork patties is expected to have positive effects in supplementing minerals, a reduction in cooking loss, a decrease in VBN, and an increase in juiciness.

  • Increasing the rice consumption, seven kinds of Nurungji which served as a home meal replacer and snack were developed with some functional materials were added, and their physiochemical characteristics were analyzed. The water binding capacity was the highest in Nurungji with black sesame seed (264.13%), and the hardness was the lowest as 0.36 N in Nurungji with Tenebrio molitor. The reducing sugar content was the highest in Nurungji with sweet pumpkin (1.47%) when being soaked in water for 30 minutes. As a result of measuring 2,2-diphenyl-1-picryl-hydrazyl free radical scavenging activity of the tested Nurungji preparations, Nurungji with sweet pumpkin and beet showed the high scavenging activity against free radicals. As a result of sensory evaluation, overall acceptability was the highest in Nurungji with black sesame seeds (4.3). Physicochemical characterization and sensory evaluation of Nurongji added with various materials confirmed that they could be applied to various food products.

  • The quality characteristics of cookies, prepared with the freeze dried fresh garlic (FGP) and steamed ($100^{\circ}C$, 20 min) garlic (SGP) powders, were investigated. The cookie samples in the present study were made by adding the garlic powders at different levels (0, 0.5, 1, 2, 4, and 6%). The highest spread ratio, $8.48{\pm}0.31$ and $8.62{\pm}0.21$, were obtained by mixing 6% FGP and 0.5% SGP with the cookies. Among the surface color of the cookies, the L-value decreased with increasing garlic powder contents compared to that of the control group, but the difference in the surface color among the kinds of garlic powders was insignificant. Although increases in the garlic powder content resulted in no noticeable difference among the a-value of the test group, the b-value was decreased significantly, particularly with increasing SGP contents. Hardness was also increased along with the garlic powder contents and was highest at its 2% content. When viewed from the sensor properties, the measured color tended to become brown at the garlic powder contents greater than 2%. The surface crack of the cookies also increased as the SGP content increased. Its garlic taste and flavor were slightly low at SGP added with 6% garlic powder content than FGP. The overall acceptability was higher in $0.5{\sim}4%$ added test samples than those in control group sample; it was highest for 1%, 2% and 0.5%, in decreasing order. In the sensor evaluation, the overall acceptability of the cookies was considerably different in the comparison of FGP added cookies with SGP added ones. Therefore, the optimal ratio investigated for making the garlic added cookies was shown to be 1 %, and its acceptability was relatively high for SGP added cookies.

  • Purpose : Echinacea, a traditional plant medicine has been used as immune-stimulant. Recent studies have revealed that extract of Echinacea has immunostimulatory effects on human blood mononuclear cells. This study was designed for the purpose of screening the genes associated with immunologic effects of Echinacea on monocytes and dendritic cells using a cDNA microarray chip. Methods : $CD14^+$ monocyte cells were cultured for one day with Echinacea extract(final concentration : $50{\mu}g/mL$) in experiment 1, but were cultured without Echinacea in experiment 2. The gene expression of these cultured monocytes was analyzed using the cDNA microarray chip. Dendritic cells produced from $CD14^+$ monocyte were cultured for five days with GM-CSF and IL-4, and then cultured for one day with Echinacea in experiment 3, but were done without Echinacea in experiment 4. Results : In experiments 1 and 2, there were 17 significantly expressed genes with average expression ratios above 2.5, including interferon gamma-inducible protein 30(IFI 30), CDC(cell-division-cylcle)-like kinase 2(CLK 2), syndecan binding protein(syntenin), superoxide dismutase 2, etc. In experiments 3 and 4, there were 24 gene, with significantly expressed genes were 24 genes, which were insulin-like growth factor 2(somatomedin A), methyl-CpG binding domain protein 3, IFI 30, small inducible cytokine subfamily A, member 22, etc. The genes encoding CD44, IFI 30, mannose receptor C type 1(MRC 1), chemokine receptor 7(CCR 7), CLK 2, syntenin and cytochrome C oxidase subunit VIII were significantly expressed in both monocytes and dendritic cells cultured with Echinacea. Conclusion : This study employed a cDNA microarray chip to elicit the immune-associated gene profile; the expression was enhanced by Echinacea in CD14+ monocytes and dendritic cells. Thus we laid the basis for the quantitative and functional analysis of genes induced by Echinacea in monocytes and monocyte-derived dendritic cells.

  • The pork cutlets containing different concentrations of dried ginseng powder (1%, 2% and 3%) were manufactured and compared the physico-chemical and sensorial properties with control containing no dried ginseng powder. The color(CIE, L, a, b) values were not significantly different between the treatments and control. The TBA values were lower for pork cutlet containing dried ginseng powder than those for control at the beginning stage (5 days) when they were vacuum packaged and stored at 4$^{\circ}C$ or 15days, however, there were not significantly different after 5 days of storage. The TBA values were remained low level (<0.5mg malonaldehyde/kg sample) when the pork cutlets were vacuum packaged and stored at -20$^{\circ}C$ for 90 days. In fatty acid composition, pork cutlet containing dried ginseng powder contained higher ratios of PUFA/SFA and lower ratios of MUFA/SFA when compared to those of control. Sensory panels evaluated that pork cutlet containing 1% of dried ginseng powder had the highest preference scores in flavor and overall palatability.
