  • To develop the functional pear fruitlet product, we prepared fermented pear fruitlet product (FPFP) from mixed fermentation of Saccharomyces cerevisiae, Kluyveromyces fragilis and Lactobacillus plantarum. Then, we investigated their several physiological functionalities. Among several physiological functionalities, antihypertensive angiotensin I-converting enzyme (ACE) inhibitory activity of the FPFP was the highest of 87.4% and its antioxidant activity was also showed 69.6%. FPFP from mixed fermentation by yeasts and Lactobacillus plantarum after thawing of frozen pear at $20^{\circ}C$ showed higher physiological functionalities than those of single fermentation by Saccharomyces cerevisiae or Bacillus subtilis after $40^{\circ}C$ of thawing.

  • We aimed to improve the flavor quality of plain yogurt, which is known to be sour and less desirable in flavor, varying concentrations of a buckwheat saccharification solution (BSS) were added to milk, followed by fermentation with commercially available mixed strains of lactic acid bacteria. Volatile compounds were analyzed using the gas chromatography-headspace-solid phase microextraction (GC-HS-SPME) method. Fermentation properties, including pH, titratable acidity, viable cells, viscosity, and color value were also measured. Eleven volatile compounds were identified with GC-MS. Of which, diacetyl, butanoic acid, and 2-heptanone proportionally increased as the levels of BSS increased. Undesirable compounds such as acetic acid and 2-butanone, decreased as BSS concentration increased. Fermentation properties were significantly altered with the addition of BSS. Our findings indicate that the flavor quality of plain yogurt can be improved by adding BSS for fermentation, with an additional health benefit from buckwheat.

  • Ginseng-whey beverages were prepared with rennet whey, ginseng, sweetener, honey and Japanese apricot, inoculated with different strains of lactic acid bacteria or unfermented partly. The samples were stored at 4$^{\circ}C$ or 30$\pm$1$0^{\circ}C$ and then physicochemical and microbiological properties were investigated. The yield of whey was 78.8%. The pH-values reduced and acidities increased during the storage period. The contents of solid-substances, ash and lipid in ginseng-whey beverages were 7.90~8.20%, 0.62~0.66% and 0.16%, respectively. The protein contents of ginseng-whey beverages were 0.42~0.56% and the contents were not changed during the storage period. The lactose contents of fermented beverages were higher than those of unfermented beverages. During the storage period (1~5 weeks), the ranges of D(-) - and L(+)- lactic acid contents in fermented ginseng-whey beverages (17.3~156.1 mg/100g, 347.3~1894.2mg/100g) were higher than those of unfermented ginseng-whey beverages (6.2~82.8mg/100g, 7.1~885.5mg/100g). The contents of total saponin in unfermented sample and fermented sample (Lac. casei sub-sp. casei+Str. salivarius sub-sp. thermophilus) were increased during the storage period. But, those of the fermented sample(Lac. acidophilus+Lac. delbrueckii sub-sp. bulgaricus) were reduced. In the electrophoretic results of ginseng-whey beverages, an $\alpha$-lactalbumin and a $\beta$-lactoglobulin bands were shown apparently and there were no changes observed during the storage period. During the storage period (1~3 week) the coliform was not detected and total plate counts and psychrotrophs were increased according to the storage period.

  • This study analyzes the effects of mixed fermented organic fertilizer on chinese cabbage growth and soil properties in order to investigate the nutritional effects of organic fertilizers, which are developed as an alternative fertilizer for imported castor oil cake. In this study, four treatments were set up: 100% and 200% rate of nitrogen application (320 kg ha-1 for Chinese cabbage) on mixed fermented organic fertilizer A(FA) and mixed fermented organic fertilizer B(FB), respectively, 100% rates of the mixed expeller cake (MEC) fertilizer, and the untreated control. Results revealed that the growth and yield of Chinese cabbage increased as more fermented organic fertilizer was used. However, while there were no significant differences in growth characteristics between treatments of 100% rate of mixed fermented organic fertilizer and 100% rate of MEC, the impacts on yields resulted similar. The nitrogen use efficiency (NUE) of Chinese cabbage was measured a range of 20-31% depending on the response to treatment. The 100% FA showed the same as NUE and nitrogen absorption with 100% rate of MEC. Regarding soil properties after cultivation, there were no significant differences among the effects of fertilizers in pH, EC, soil organic matter, and available phosphate. However, the content of exchangeable cations(K, Ca, Mg) was higher in areas treated with mixed fermented organic fertilizer than in untreated areas. Furthermore, the bacterial population density in the soil was higher in areas treated with mixed fermented organic fertilizer than in untreated areas and increased as more mixed fermented organic fertilizer was used. There were no significant differences in the population density of actinomycetes and fungi when fertilizer was applied to the soil. These results also show that FA, as a alternative organic fertilizer for imported castor oil cake, has similar nutritional effects as that of MEC. Therefore, further research the appropriate amounts of fertilizer is required to achieve economical and eco-friendly nutrient management.

  • We examined the macrophage activity of Codonopsis lanceolata and its effect on the growth of lactic starter culture when it was added to fermented milk. Nitric oxide(NO) and interleukin-1${\alpha}(IL-1{\alpha})$ were increased significantly(p<0.05) by addition of Codonopsis lanceolata water extract at $1,000\;{\mu}g/mL$. Tumer necrosis factor-${\alpha}(TNF-{\alpha})$ was increased significantly (p<0.05) by addition of Codonopsis lanceolata water extract or 70% ethanol extract at $1,000\;{\mu}g/mL$. Water extract of Codonopsis lanceolata showed higher macrophage activity than 70% ethanol extract. Growth of lactic starter culture was inhibited by the increased addition of Codonopsis lanceolata water extract, resulting in less decrease in pH. A stirred type or drink type fermentation process seemed mote suitable than a set type in proper production of Codonopsis lanceolata extract added fermented milk.
