  • Effects of various sub-ingredients (hot pepper, garlic, ginger, green onion, leek, salted and fermented anchovy juice, and sugar) on the sensory quality of Korean cabbage kimchi were investigated. Sixteen sensory attributes were selected and their intensities evaluated by 20 panelists. The kimchi had an unbarmonized taste and unpleasant flavor when fermented with individual sub-ingredients, but had a well harmonized taste when fermented with all sub-ingredients. Hot pepper, ginger and garlic contributed to reduction of the unpleasatnt taste and moldy odor. The strong garlic flavor was reduced by adding green onion and leek. Salted and fermented anchovy juice gave a palatable taste, and the overall taste was improved by adding sugar. All sub-ingredients except sugar reduced the sour tasts.

  • To improve the quality of Gulbi, 10% garlic juice (GJ), 10% onion juice (OJ), and 10% garlic and onion juice mixture (GOJ) were added to the brine solution as a wet-salting method. The changes of total volatile basic nitrogen (TVB-N) and trimethyl amine (TMA) production, thiobarbituric acid reactive substance (TBARS) value, and total microbial numbers in Gulbi were analyzed during storage at room temperature for 12 days. The group treated with 10% GOJ showed the lowest values of 88.2 mg/l00 g in TVB-N, 14.13 mg/l00 g in TMA, and 3.1 $\mu$mol/kg in TBARS. The fatty acid profile of Gulbi was analyzed on 5, 15, and 30 days to investigate the effect of GOJ treatment. The group treated with GOJ showed higher C22:6 (9.91%) and C20:5 (4.25%) contents than control (7.37% and 3.71%, respectively), but had lower C18:1 (24.44%) content. The saturated fatty acid content in Gulbi was 32∼35% and the C16:0 (21∼23%) was predominant in it. Oleic acid was major unsaturated fatty acid in Gulbi. The contents of polyunsaturated fatty acids (C18:3, C20:5, C22:6) were decreased after 30 days but increased the saturated fatty acid (C16:0) and monoenes (C16:1 and C18:1). The Gulbi treated with GOJ by brine salting method showed higher DHA and EPA (9.91% and 4.25%, respectively) contents than the control group.

  • The contents in large intestine of Sprague Dawley rats fed polygalae radix(Polygala tennuifolia), onion(Allium cepa) and mugwort(Artemisia asiatica)-supplemented diets for 14 days were analysed for changes of major intestinal microflora, activities of ${\beta}-glucosidase\;and\;{\beta}-glucuronidase$ and amounts of putrefactive products such as indole and volatile basic nitrogen. The rats having ingested $5%{\sim}10%$ mugwort water or ethanol extract-supplemented diets showed a significant increase in intestinal bifido-bacteria and a decrease in clostridia and E. coli (p<0.05). And 10% onion juice group also showed a similar beneficial microflora change. In 5% mugwort powder-supplemented group, ${\beta}-glucosidase\;and\;{\beta}-glucuronidase$ activities in the intestinal contents were lowered, but the changes were not significant. Indole contents and pH in this group were significantly low compared with that of control (p<0.05). However, the activities of ${\beta}-glucosidase$ in 5% polygalae radix water extract and 10% onion juice-supplemented group and ${\beta}-glucuronidase\;in\;5%{\sim}10%$ mugwort water and ethanol extract-supplemented group were significantly higher than those of control (p<0.05). The intestinal indole contents of rats were significantly increased by feeding diet with water extract of polygalae radix and ethanol extract of mugwort which had brought comparatively large amount of protein in intestine (p<0.05). However, polygalae radix, onion, and mugwort-supplemented group had no effect on volatile basic nitrogen.

  • Lactic acid bacteria (LAB) isolated from various fruits and vegetables were screened in order to determine appropriate fermentation starters for manufacturing functional fermented onion juice. From the initial screening test comprising more than 700 isolated LAB, 16 isolates were selected based on their acid production rate. Among the selected isolates, the fermentation broth of KC-007 exhibited the highest electron donating and nitrite scavenging activities, with values at pH 1.2 of 95.6 and 68.7%, respectively. From the overall results obtained in this study, we finally selected the bacterium KC-007 as a fermentation starter. This bacterium was identified and named as Pediococcus pentosaceus based on its morphological and physiological characteristics, carbon-utilization pattern (as assessed using an API 50CHL kit), and molecular genetic characteristics (as assessed using the nucleotide sequence of the 16S rRNA gene). The optimal temperature, pH, and starter inoculation concentration (v/v) required for growth of the isolated strain were $40^{\circ}C$, pH 4.0-6.0, and 2%(v/v), respectively.

  • Development of an effective method for the preparation of dongchimi juice was investigated by addition of NaCl, sucrose and hydrolytic enzymes before fermentation and addition of dongchimi juice during fermentation. The Chinese radish was ground and suspended in water (1:1, w/v) with addition of spices of garlic, green onion and ginger followed by fermentation at $25^{\circ}C$. Increase in NaCl concentration of brinning solution from 1.0 to 5.0% resulted in a significant decrease in the rates of pH decrease and acidity increase. The sugar addition resulted in a faster changes of them, particulary after 24 hours at $25^{\circ}C$. The fermentation rate was also greatly improved by enzymatic hydrolysis with using viscozyme, a commercial polysaccharides hydrolyzing enzyme, before fermentation. When the fermented juices of two stage (pH 5.4 and pH 4.4) were added up to 15% before (pH 5.4 juice) and during (pH 4.4 juice) fermentation, the initial and second stage of fermentation were significantly improved. Therefore a method of addition of sugar, hydrolytic enzymes and dongchimi juice before or during fermentation was suggested for dongchimi juice preparation.

  • Onion juices supplemented with different concentrations of puffed red ginseng extract were fermented using Pediococcus pentosaceus KC-007 and their biologically functional properties were investigated. When onion juices were supplemented with puffed red ginseng extract at the concentration of 0.5, 1, 2, and 4% (v/v) each, viable cell number of lactic acid bacteria was the highest at 24 hr of fermentation in all samples. The titratable acidity increased as the fermentation proceeds irrespective of the added amount of red ginseng extract, and the pH of fermentation broth decreased until 36 hr of fermentation. The reducing sugar of fermentation broth decreased until 24 hr of fermentation and did not change thereafter. The electron donating ability and nitrite scavenging ability were highest when red ginseng extract was added at the concentration of more than 1% (w/v). The overall acceptance in sensory evaluation was the best when red ginseng extract was added at the concentration of 1% (w/v). From these results, it is confirmed that the optimum concentration of puffed red ginseng extract for the lactic acid fermentation of onion juice was 1% (w/v).

  • The purpose of this study was to investigate the extraction yield and quality stability as to the oleoresin process with large amount of onion at one time. The first mixed-product is raw onion juice which was reduced the compression and concentrated by Brix 70% mixed together wit the residue which was extracted and concentrated by ethanol, the second product manufactured by the same method above after the autoclaving with onion, and the other product is made by grinding by 50mesh to freeze-dried onion. Each of yields were 7.3, 9.1 and 0.8% and each of total sugar content was 616.4, 712.3 and 150.3mg/g. Therefore the product extracted by ethanol from freeze-dried onion was very low in yield and total sugar content. By the index of the overall odor intensity, contents of total pyruvate were 1,733.7, 520.6, and 2,716.5$\mu\textrm{g}$/g for each product. As a result, oleoresin onion processing that desired to use raw onion was remarkable for odor recovery. For the homogenous mixture with concentrate of onion juice and ethanol extract were emulsified by the addition of 2% of PGDR(polyglycerol condensed ricinoleate) and agitation(10,000rpm, 30 minutes). At this time, interfacial tension was 1.9 dyne/cm and the formation of emulsion was for 96.2% when left over 24hours in 6$0^{\circ}C$. When it was to be centrifuged(2,000$\times$G, 80 minutes) after emulsification, the volume of emulsion level without seperation was 92.6%, and very high in emulsification stability. The induced heating-oxidize with soy bean oil and sesame oil added to 1% of onion oleoresin, induction-time extension effect appeared with antioxidant activity that was applicable for 80.8~82.2% as to the effect of addition of 0.02% BHA.

  • This study was carried out to investigate some antioxidative effects of stewed pumpkin juice (SPJ) and the SPJs added with ginger (SPJ-G), onion (SPJ-O), jujube (SPJ-J) or boxthorn (SPJ-B), respectively, on the lipid oxidation of soybean oil (S) and mackerel pike boiled ground (MPBG). Antioxidative substances of SPJ were extracted by using the two solvent layers of n-hexane:acetone (1:1)(H) and methanol:water (7:3)M. The antioxidative effects of the extracts were observed by the peroxide value (P.O.V.) and thiobabituric acid (T.B.A.) value. The P.O.V. and T.B.A. value of two solvent extracts of S and MPBG showed significantly lower than those of S and MPBG. The SPJ showed very distingnished antioxidative effects. It was considered that melanoidine extracted by using methanol:water (7:3) solvent as well as carotenoid extracted by using n-hexane:acetone (1:1) solvent had an antioxidative effect. During storage, T.B.A. value of MPBG significantly increased, while that of MPBG-SPJ significantly decreased more than that of MPBG. T.B.A. value of MPBG-SPJs decreased much than that of MPBG-SPJ, SPJ-O, SPJ-G, SPJ-J and SPJ-B, in order of abundance, showed higher level of antioxidative effects than SPJ.
