The objective of this study was to improve the qualities of Saengsik (substitute meal formulated with uncooked cereal powder) such as functionality, safety and sensory preference by using Lactic Acid Bacteria (LAB). The optimum formulation of fermented Saengsik (substitute meal) was verified as $40\%$ of fermented brown rice, $13\%$ of fermented job tears, $5\%$ of yellow soybean, $5\%$ of waxy rice, $5\%$ of sorghum, $3\%$ of Seumok bean, $1\%$ of sesame, $3\%$ of barley, $2\%$ of red bean, $5\%$ of prosomillet, $2\%$ of foxtail millet, $9%$ of black rice, $3\%$ of buckwheat, $1\%$ of chestnut, $2\%$ of pumpkin, $3\%$ of peanut. Fermented Saengsik decreased significantly serum glucose in STZ-induced diabetic rats. However, serum lipid levels were not affected by fermented Saengsik. In rats fed with high-fat diet, serum triglyceride level was slightly decreased and the contents of liver triglyceride were significantly decreased by supplementation of fermented Saengsik.

This study was conducted to investigate the effects of dietary supplementation of various types of fermented red ginseng marc with red koji to laying hens on eggshell and egg yolk quality characteristics. A total of 240 Hy-line Brown laying hens (40 wk of age) were randomly allotted to 24 pens (6 replicates per treatment and 10 laying hens per replicate). Experimental diets consisted of 4 treatments containing basal diet (control), 1% fermented red ginseng marc powder with red koji, 1% fermented red ginseng marc pelleted with red koji and 1% fermented red ginseng marc coated with red koji. During the 8-wk feeding trial, there were no significant differences in eggshell strength, eggshell thickness and eggshell color among the treatments, except for eggshell strength at 4 and 8 wk and eggshell thickness at 0 wk. In addition, no differences in egg yolk color and egg yolk index were found for all treatments throughout the 8-wk feeding period, except for egg yolk color at 0 wk. Thus, using various types of fermented red ginseng marc with red koji to laying hens did not improve eggshell and egg yolk quality characteristics.

Sensory analysis and quality properties were performed on post-aged doenjang (fermented soybean pastes) in order to elucidate the contribution of citrus, green tea and cactus powder to their sensory evaluation. The doenjang added citrus fruits, green tea and cactus powder used a concentration of 0, 3 and 7% (w/w) at 4, 20, $30^{\circ}C$ respectively and analyzed the proximate composition, pH, salt, mineral and amino acid contents after 60 days. Moisture and protein changes during ripening did not show any significant difference. The pH showed lower in the doenjang added citrus and cactus powder than no added soybean paste. The glutamic acid content of doenjang added citrus fruits showed a little decreasing value although there were no differences between samples with various addition contents. Sensory evaluation of doenjang showed that there were no significant differences in preference in the case of added green tea and cactus powder; However, the flavor significantly increased doenjang added 3% citrus powder at $30^{\circ}C$. These results showed that the preference of doenjang containing 3% citrus powder was superior to green tea and cactus powder.

Effects of kimchi and its ingredients, vitamin C and $\beta$-sitosterol on the growth of Helicobacter pylori were investigated. Three kimchi variations were studied: a standard recipe (kimchi I) and two functional variations for cancer prevention and treatment made with organically grown ingredients (kimch II and III). Methanol extracts and juices from kimchi I and III did not inhibit the growth of H. pylori. However, 10 mm and 12 mm inhibition zones were formed by methanol extract and juice from kimchi II, which had higher concentrations of red pepper powder (RPP) than those of kimchi I and III. Among the major kimchi ingredients, methanol extracts of RPP, garlic and ginger substantially inhibited the growth of H. pylori. The maximal inhibition zone (30 mm) was attained with garlic treatment. Inhibitory effects of the RPP, garlic and the sub-ingredient mixture (prepared with radish, garlic, RPP, ginger, green onion, sugar and fermented anchovy juice) on H. pylori were decreased by lactic acid bacteria fermentation. Neither the fermented garlic nor the fermented sub-ingredient mixture inhibited the growth of H. pylori. But, the inhibition Bone of fermented RPP was 12 mm, which was less than the 16 mm inhibition zone formed by the non-fermented RPP. Vitamin C and $\beta$-sitosterol which are known to be functional active compounds of kimchi also showed no inhibitory effect on the growth of H. pylori after 3 days of incubation. Further study is needed to determine why the inhibitory effect is removed or decreased by lactic acid fermentation, and to determine if fresh kimchi and lactic acid bacteria of kimchi can inhibit the growth of H. pylori.

This research investigated the relationship between the amount of fixed pigment and the color of silk dyed with three types of fermented indigo powder dye under different temperatures and pH, by reduction or nonreduction method. Amount of fixed pigment was analyzed using the Ultimate 3000 HPLC-DAD instrument and the color of dyed silk was measured using the X-rite spectrocolorimeter. All silk samples dyed by reduction method showed PB color. The amount of indigotin fixation was dependent on the dyeing temperature and pH regardless of the indigotin composition in the dye. Indirubin was less dependent upon the dyeing condition in the reduction dyeing and its fixation was minimum level. Dyeing conditions which can maximize the indigotin fixation were $50^{\circ}C/pH$ 11 and $70^{\circ}C/pH$ 7 conditions in reduction dyeing. Color of silk showed more redness ($a^*$) thus higher PB color when the indigotin fixation was low and indirubin fixation was relatively high. Indirubin fixation was very low with slightly better fixation by nonreduction method. More reddish color was obtained by nonreduction dyeing, and by more alkaline dyebath.

This study investigated the physicochemical properties and physiological activities of jelly prepared from gelatin, sugar, bokbunja extract, and different amounts (0, 0.5, 1, 2 and 3%) of fermented sea tangle Saccharina japonica powder (FSP). The jelly moisture, pH, and sugar content slightly increased with increasing the FSP content. Hardness, springiness, gumminess, chewiness, and cohesiveness also increased with increasing FSP concentration. Jelly antioxidant activity did not change significantly with increasing FSP. In contrast, alcohol dehydrogenase and aldehyde dehydrogenase activities in the jellies increased significantly with increasing FSP concentration. β-secretase inhibitory activity in jellies also increased with increasing FSP concentration. Jellies containing 0.5 or 1% FSP achieved the highest overall sensory acceptance scores. Taken together, these data indicate that addition of FSP to jelly appears to improve its quality and physiological activities.

This study was carried out to compare quality characteristics and physiological activities of Korean traditional wines fermented by addition of puffed sorghum powder. Using a two-step brewing process for fermented wines, pH, acidity, ethanol, color, tannin, ${\alpha}-glucosidase$ activities, antioxidant, and reducing sugar levels as well as sensory evaluation were measured during fermentation at 2-day intervals until day 8. The pH levels of fermented wines ranged from 4.07 to 5.53, and acidity ranged from 0.13 to 0.86. On the last day of fermentation, alcohol contents of control, raw sorghum, steamed sorghum, and 25, 50%, and 100% puffed sorghum were 16.8%, 11.7%, 13.4%, 16.5%, 15.2%, and 16.4%, respectively. The reducing sugar and ${\alpha}-glucosidase$ activities of puffed sorghum fermented wines were relatively higher than those of the control group, whereas those of steamed sorghum were lowest. As puffed sorghum powder content increased, antioxidant activity significantly increased. In the results of the sensory evaluation, overall preference of 50% puffed sorghum fermented wines was highest among the samples. The results of this study show that physiological activity and quality characteristics of fermented wines containing puffed sorghum powder contribute to value added improvement of sorghum processing.

In this study, silk fabrics was dyed with sappan wood extracts fermented for 5 and 15 days, respectively, and then the dyeability, durability and the functionality of the dyed silk were investigated. Before dyeing, the silk was pretreated with chitosan-acetic acid solution or chitosan acetic acid and illite blend solution. Thereafter, UV-Visible transmittance, color, fastness, antimicrobial activity, and the FIR emissivity were analyzed. As a result, the K/S value was higher in the samples that were not pre-treated or fermented. Regardless of fermentation, the lightfastness was not significantly different. The color fastness to washing was slightly better when the samples were pretreated with chitosan-acetic acid and illite, and then dyed with extracts fermented 5 days. In addition, all samples showed high antimicrobial activity of 99.9%, regardless of the fermentation. Far-infrared emissivity was confirmed to be slightly increased by the illite and chitosan-acetic acid solution treatment compared to the untreated sample.

Purpose: This study investigated the question of whether the addition of natural ingredients (pear fermented solution, celery powder, vitamin C) in curing agents may influence antioxidant activities and nutritional characteristics of smoked duck. Methods: Smoked duck samples with general or natural curing agent containing three additive ingredients were examined to determine total polyphenol contents, antioxidant activities, pH, TBARS, and food additives residue (nitrite ion, antioxidant, sodium glutamate). Results: Smoked duck with natural curing agent showed a higher level of total polyphenol content and antioxidant activities than smoked duck using general curing agent (p < 0.05). The pH and TBARS of smoked duck were significantly decreased by the addition of natural curing ingredients compared to those of smoked duck using general curing agent (p < 0.05). The residues of food additives were not detected in smoked duck using natural curing agent. Conclusion: Findings suggest that the addition of pear fermented solution, celery powder, and vitamin C in natural duck curing agent may improve the antioxidant activities and nutritional characteristics of smoked duck and provides health benefits.
