  • To produce alcohol from Mume (Prunus mume Sieb. et Zucc) fruits, fermentation conditions were optimized by a response surface methodology (RSM) using the fractional factorial design with 3 variables and 5 levels. The coefficient of determination ($R^2$) of response surface regression equation for alcohol production were 0.9276. Optimum conditions for alcohol production were involved with 8.39% of sugar content, 28.86$^{\circ}C$ of fermentation temperature and 3.84 days of fermentation time. Finally, predicted level of alcohol production at these conditions was 5.24%.

  • This study was designed to investigate the antioxidant effects of 10 kinds of medicinal plants and vegetable extracts and total extracts. The cytotoxicity was measured by MTS assay, and the antioxidant activity was measured by DPPH free radical scavenging activity and Riboflavin-derived superoxide inhibitory activity (SQA). As a result, cytotoxicity was safe for all 10 medicinal plants, vegetable extracts and total extracts. DPPH free radical scavenging ability was observed in Cinnamomum cassia Blume, Eugenia caryophyllata Thunb. Arctium lappa, Total extract was excellent, and Riboflavin-derived superoxide inhibitory activity (SQA) was found in Cinnamomum cassia Blume, Arctium lappa, Prunus mume Sieb. et Zucc., Excellent, but total extract showed the best antioxidant effect. As a result of comparing the antioxidant effects of medicinal plants and vegetables using traditional ingredients, the antioxidant activity was increased when used as a mixture than when used alone. It is considered that it can be used as an antioxidant functional material, and it is expected to be of value when developing antioxidant material in the future.

  • The optional ingredient, Maesil juice, was adopted to improve the quality of Yulmoo Mul-Kimchi during fermentation. The final weight of the Maesil juice as a percentage of the water content in the Yulmoo Mul-Kimchi was adjusted to 0, 1, 3, 5 and 7%. The physicochemical, microbiological and sensory characteristics were determined during fermentation at 10$^{\circ}C$ over a 30 days period. After fermentation, the additions of 3 and 5% Maesil juice gave the highest pH values and lowest total acidities. With regard to the reducing sugars, the 3 and 5% treatments gave the highest contents. The number of the total cell count and lactic acid bacteria increased to their maxima during fermentation, but began to decrease during the latter stages. Here, the additions of 3 and 5% Maesil juice showed distinctive lower and higher numbers of total cells and lactic acid bacteria, respectively, during the latter stages of fermentation. With regard to the sensory evaluation on the addition of Maesil juice, the results obtained with 3 and 5% additions to the fermented Yulmoo Mul-Kimchi were favored for color, smell, sour and carbonated tastes and overall acceptability of the products. Therefore, the optimum levels of Maesil juice addition to Yulmoo Mul-Kimchi were estimated to be between 3 and 5%.

  • Effect of the thickness of low density polyethylene(LDPE) Film as packaging material on changes in physicochemical characteristics of mature-green mume (Prunus mume Sieb. et Zucc) fruits during storage at different temperatures(0, 10 and 25$\^{C}$) were investigated. Fruit samples stored in pouches with 30㎛ thickness of LDPE film maintained well not only external qualities such as Shape and firmness, but also internal chemical properties such as pH, acidity, the content of soluble solid and chlorophyll, and color, comparing with samples stored without packaging material or in other pouches with different film thickness(20 and 40㎛). From the results, it was found that the maintenance of quality of mature-green mume fruits during storage at 0, 10 and 25$\^{C}$ closely related to the changes in respiratory conditions for fruits affected by the film thickness of the packaging material.

  • This study was determined to change in chemical composition of Mume(Prunus mume Sieb. et Zucc) fruits during maturation. There were no differences in the soluble solid and moisture content among varieties, but the soluble solid slowly increased with maturing. The pH and ash content were slightly decreased with maturation. The green color of 'Nanko' fruits was maintained for 92days after full bloom at the greeness value of -3.81 Whereas, the chlorophyll content of 'Koume' fruits remarkably decreased and it was not suitable for the processing of immature green Mume fruits. The titratable acidity increased during maturation. The organic acids were mainly composed of malic acid and citric acid. The malic acid was significantly decreased during maturation, whereas citric acid increased. Major free sugars and sugar alcohols were sucrose, glucose, fructose, sorbitol and maltose. Sucrose content increased as the maturity proceeded, whereas glucose and sorbitol were decreased. The total contesnt of free amino acids decreased with maturation and the total free amino acids in the flesh of fruits were occupied by asparagine at the range of 60 to 78%.

  • Prunus mume Sieb. et Zucc is distributed throughout Asia and has traditionally been used as medicine and food. P. mume is known to contain large amounts of various organic acids, minerals, and phenol components. To date, the trend of P. mume research has focused only on the effects of antioxidant, anticancer and antibacterial, with only a few studies have focused on angiogenesis. Angiogenesis is a common characteristic of metastatic cancer through which oxygen and nutrients are delivered to the cells and tissues. In the present study, angiogenesis-inhibiting activity was investigated by evaluating the total polyphenol and flavonoid contents of the P. mume butanol fraction (PBF) and their ability to inhibit VEGF-induced human umbilical vein endothelial cells (HUVECs) proliferation, migration, invasion, and capillary formation. The polyphenols (12.81 mg GAE/g) and flavonoids (28.4 mg QE/g) of the PBF exhibited high antioxidant activity. The results of this study showed that PBF did not inhibit the proliferation of HUVECs at concentrations of 25-200 ㎍/ml and did not exhibit toxicity to normal cells. However, PBF inhibited the VEGF-induced mobility, invasion, and capillary formation of HUVECs. These results show that PBF inhibits the angiogenesis of HUVECs induced by VEGF. Therefore, PBF could serve as a therapeutic agent for the inhibition of angiogenesis.

  • Bacterial canker of Japanese apricot (Prunus mume Sieb. et Zucc.) was found in all orchards located at southern area of Korea. Typical symptoms were characterized by dark spots formed on fruits, brown lesions on leaves, and bacterial exudate oozed out of the cracked bark of diseased tree. Thirty-eight isolates from 16 different areas were identified on the basis of biochemical and physiological characteristics (LOPAT and GATTa test) and also on the basis of 165 rDNA and ITS sequences. Pathogenicity tests confirmed that bacterial canker of Japanese apricot in Korea is caused by Pseudomonas syringae pv. morsprunorum.

  • The effects of Japanese apricot(Prunus mume Sieb. et Zucc.) flesh on baking properties of white breads were investigated by evaluation of specific loaf volume, pH, acidity, rheological property, color and sensory quality. Bread was processed by adding 4.7%, 9.4%, 14.1% and 18.8% of Japanese apricot flesh to basic formulation. The compositions of Japanese apricot flesh were 88.19% moisture, 0.45% crude ash, 4.10% dietary fiber, 4.04% citric acid and 0.41% total sugars. The specific loaf volume of the breads was decreased from 3.274mL/g to 1.857mL/g as Japanese apricot flesh contents increased from 0% to 18.8%. The pH of the breads decreased but the acidity of those increased as the percentage of Japanese apricot flesh to wheat flour increased. Lightness(L value) of the breads decreased by the addition of Japanese apricot flesh, while yellowness(b value) and redness(a value) increased. Texture measurement showed that springiness, cohesiveness and resilience decreased with increase of Japanese apricot flesh contents. While, hardness, gumminess and chewiness were the lowest in the bread with 9.4% Japanese apricot flesh, and increased in the bread with 4.7%, 14.1% and 18.8% Japanese apricot flesh contents. In sensory evaluation, the highest sensory scores for flavor, taste, aftertaste and overall acceptability were obtained when Japanese apricot flesh content was 4.7%, and softness and chewiness was the best when 9.4% of Japanese apricot flesh was added. The moisture content of the breads containing Japanese apricot flesh was higher than that of the control to add no flesh during storage at $25^{\circ}C$. Based on physical, rheological and sensory evaluation, addition of 4.7{\sim}9.4% Japanese apricot flesh suggested to be acceptable for processing bread.
