  • Objectives : This study was aimed at investigating liver protection mechanism of bear bile juice (Fel Ursi)by inducing liver toxicity through $CCl_4$ in mice and evaluated histological and serological findings. Methods : Experiment groups was categorized into untreated normal group, $CCl_4$ treated control group, and orally administered bear bile juice experiment group. At the termination of experiment, gross examination of the liver as well as histological findings, and Total protein, Albumin, Total bilirubin, Direct bilirubin SGOT, SGPT, and ALP contents in the serum were evaluated. Results : 1. For gross examination and histological findings, $CCI_4$ treated control group showed destroyed lobular structure, increased fibrosis, as well as hepatic cirrhosis. For the group treated with bear bile juice, the lobular structure suffered less damage, and showed lower level of fibrosis and liver cirrhosis compared to the control group. 2. For serum analysis, Total protein and Albumin were significantly increased in the bear bile juice experiment group than the control group. Total bilirubin and Direct bilirubin didn't show significant differences between the two groups. SOOT, SGPT, and ALP were significantly decreased in the normal and bear bile juice experiment groups compared to the control group. Conclusion : Taken together, bear bile juice can be effectively used for recovering the liver functions and further researches must be conducted to verify the efficacies of bear bile juice.

  • This study was performed to investigate the quality characteristics of Yanggeng added wild grape (Vitis amurensis) juice. The yanggeng was prepared with pesticide-free wild grape juice, agar, sugar and salt. The yanggeng was made with various levels (0, 50, 100, 150, 200 g of wild grape juice in yanggeng, respectively) based on the total weight of water. It was estimated on Hunter's color value, texture profile analysis, and sensory characteristics of the Yanggeng. As the content of wild grape juice increased, The lightness (L) and yellowness (b) decreased and redness (a) increased. In texture profile analysis, hardness was increased; however, springiness, cohesiveness, gumminess and chewiness decreased with increasing levels of wild grape juice. The results of the sensory evaluation indicated that the Yanggeng containing the 150 g level of wild grape juice showed the highest preference scores in terms of color, taste, texture, flavor and overall acceptance. These results show that the yanggeng containing 150 g of wild grape juice is the better.

  • The effects of pretreatment by freezing on juice expression and drying characteristics of Prunus mume fruit were investigated. Fresh fruit slices were frozen at $-20^{\circ}C$, thawed, and then either pressed (to yield juice) or dried. Fresh fruit slices were used as controls. Both juice yield and drying rate were higher when pre-frozen fruit was tested, compared to fresh fruit. The L and b color values were lower in the juice and dried powder of pre-frozen compared to fresh fruit. The a color value was higher in juice and powder prepared from pre-frozen fruit compared to fresh fruit. There was no significant difference in free sugar or organic acid content between juices and powders from pre-frozen and fresh fruit. None of soluble solid content, titratable acidity, or juice pH was affected by freezing pretreatment. The results suggest that such pretreatment may be useful to increase juice yield and drying rate. However, browning of juice and powder may be elevated.

  • Juice of Dongchime a Korean traditional vegetable food fermented with lactic acid bacteria has been traditionary used as broth for Naengmyon a Korean cold noodles with broth. This study was carried out to demonstrate the growth inhibition of two food born pathogens Listeria monocytogenes and Escherichia coli O157:H7 in Naengmyon-broth containing Dongchimi-juice fermented with high antibacterial lactic acid bacteria Lactobacillus homohiochii B21 and Leuconostoc mesenteroides C16. Naengmyon-broth were made with beef broth and Dongchimi-juice fermented with lactic acid bacteria and the changes in viable cell counts of the inoculated pathogens in Naengmyon-broths were investigated during storage at 2$0^{\circ}C$ and 1$0^{\circ}C$. In Naengmyon-broth of 100% Dongchimi-juice stored at 2$0^{\circ}C$ the numbers of Listeria monocyto-genes and Escherichia coli O157:H7 were rapidly decreased from 106CFU/ml to 106CFU/ml in 8 hours and 40 hours respectively. In Naengmyon-broth containing 50% Dongchimi-juice their numbers were also rapidly decreased though the decreasing rates were not so fast as those in 1005 Dongchimi-juice. In Naengmyon-broth containing 10% Dongchimi-juice the growths of the two pathogens were markedly inhibited compared with those in 100% beef broth though some growths were occurred in early phase. But in Naengmyon-broth of 100% beef broth their growths were very fast from early. Antibacterial ac-tivity of the Dongchimi-juice was more distinct at 2$0^{\circ}C$ than at 1$0^{\circ}C$ and was more active against Listeria monocytogenes than against Escherichia coli 157:H7.

  • It has been suggested that green juice supplementation may have some health promoting benefits. We evaluated the effects of green juice (Angelica keiskei) consumption on parameters of lipid profiles and plasma antioxidant status in healthy male smokers. Fifty-four smokers were supplemented with 300 ml of green juice for 6 weeks while maintaining their normal diet. Blood samples were collected on week 0 and week 6 in order to evaluate plasma lipid profiles (total cholesterol, triglyceride, LDL-cholesterol, HDL-cholesterol) , plasma antioxidant vitamin levels (ascorbic acid, $\alpha$ -tocopherol, ${\gamma}$ -tocopherol, $\alpha$ -carotene, $\beta$ -carotene, cryptoxanthin and lycopene) , the degree of LDL oxidation and GOT, GPT levels for liver function. Plasma ascorbic acid level remained at the same level. However, $\alpha$ -tocopherol and ${\gamma}$ -tocopherol normalized by total cholesterol (p <0.05) and $\beta$ -carotene (p <0.001) level were all significantly increased after green juice supplementation. Plasma cholesterol was reduced for 12%, LDL-cholesterol was reduced for 9.3% after green juice consumption, while plasma triglyceride and HDL-cholesterol was not changed. Oxidized LDL assessed by conjugated diene (CD) , was decreased (p < 0.0001) after green juice consumption. These results further support a role for green juice supplementation in the improvement of lipid status, prevention of lipid peroxidation, and thereby reducing risk factors of numerous diseases associated with elevated oxidative stress in smokers.

  • Radish green juice was used as a dual source for the production of plant protein precipitate and Candida utilis biomass. Precipitates ranging from 10.0 to 16.5g were obtained from a liter of radish green juice by heating at 80-10$0^{\circ}C$C for 1 to 10 min or by modification of the pH of radish green juice. Crude protein content of the precipitate was between 25 and 38%. The residue remaining after protein precipitation was used in turn for the cultivation of the yeast, C. utilis, in order to produce yeast biomass. C. utilis grew well in radish green residual juice and completed growth within 24 hr at 3$0^{\circ}C$ and 200rpm in shake flask experiments. Maximum dry cell weight obtainable from a liter of radish green residual juice was 19.5g, when the yeast was grown on the juice residue diluted 3 times or more with water to make sugar content be equal to or less than about 1.0%. Supplementation of 3-fold diluted radish green residual juice with yeast extract and (NH$_4$)SO$_4$ enhanced yeast biomass production and cell protein content significantly. Total high protein material obtainable from a liter of radish green juice was 33.0g.

  • The present study investigated the influence of different volumes of red hot pepper juice on the quality characteristics of fresh Pasta noodle. Supplementation with 0% (control), 2.5%, 5%, 7.5%, or 10% red hot pepper juice produced similar gelatinization characteristics of peak viscosity, temperature at peak viscosity, hot paste viscosity and numerical value of breakdown. However, increasing concentrations of red hot pepper juice produced progressively and significantly low cold paste viscosity and setback. The chromaticity of wet and cooked noodles was significantly lower in L value and significantly higher in +a and +b values with increasing volumes of red hot pepper juice. The texture of fresh noodles displayed no significant differences in hardness, adhesiveness and chewiness. The springiness and cohesiveness were lower and higher with the increase of added red hot pepper juice, respectively, but the differences just attained significance. For cooked noodles, adhesiveness, springiness, cohesiveness and chewiness tended to be higher with increasing volumes of red hot pepper juice, but again the differences just attained significance. Cooking characteristics of weight, volume, moisture absorptive power and turbidity decreased with increasing volumes of red hot pepper juice. Sensory characteristics of acceptability including appearance, color, flavor, taste, texture and overall-acceptability improved with increasing red hot pepper juice volume, in particular with 5% and 7.5%. Amylograph characteristics for initial paste temperature positively correlated with the texture characteristics for chewiness (p<0.05). Negatively correlated amylograph parameters included texture for springiness with for peak viscosity (p<0.01), texture for adhesiveness with hot paste viscosity (p<0.01) and breakdown with texture for adhesiveness, cohesiveness and chewiness (p<0.05).

  • This study aimed to determine the physical properties of silk and nylon fabrics that are treated with persimmon juice in accordance with irradiation time of ultraviolet spectrum. Persimmon juice dyeing has the advantage of using the tannin component of the persimmon. Tannin plays an important role in inhibiting photodegradation of fibers or polymers. Among fibrous materials, silk and nylon are prone to deterioration by light. Hence, this study aimed to reduce these weaknesses of silk and nylon by applying persimmon juice treatment. We accordingly carried out investigation and experiments on ultraviolet irradiation, and physical characteristics of treated fabrics. The persimmon juice treatment process led to increased weight and thickness. In addition, the air permeability of silk fabric was increased, as compared to the control specimen; whereas, that of nylon fabric was decreased. Both drape stiffness and flex stiffness of silk and nylon tended to be high in textiles processed with persimmon juice treatment, as compared to the control textile. Peak load and elongation at peak load of untreated samples clearly decreased in both silk and nylon fabrics with the increase of ultraviolet irradiation time, while those of persimmon juice treated samples increased. Furthermore, ultraviolet blocking ratio measurement indicated that the fabric specimens treated with persimmon juice blocked U.V. spectrum better than the control specimen.

  • The aim of this study was to investigate the protective effects of juice powders from sweet orange [Citrus sinensis (L.) Osbeck], unshiu mikan (Citrus unshiu Marcow), and mini tomato (Solanum lycopersicum L.), and their major flavonoids, hesperidin, narirutin, and rutin in tert-butyl hydroperoxide (t-BHP)-induced oxidative stress in HepG2 cells. The increased reactive oxygen species and decreased glutathione levels observed in t-BHP-treated HepG2 cells were ameliorated by pretreatment with juice powders, indicating that the hepatoprotective effects of juice powders and their major flavonoids are mediated by induction of cellular defense against oxidative stress. Moreover, pretreatment with juice powders up-regulated phase-II genes such as heme oxygenase-1 (HO-1), thereby preventing cellular damage and the resultant increase in HO-1 expression. The high-performance liquid chromatography profiles of the juice powders confirmed that hesperidin, narirutin, and rutin were the key flavonoids present. Our results suggest that these fruit juice powders and their major flavonoids provide a significant cytoprotective effect against oxidative stress, which is most likely due to the flavonoid-related bioactive compounds present, leading to the normal redox status of cells. Therefore, these fruit juice powders could be advantageous as bioactive sources for the prevention of oxidative injury in hepatoma cells.

  • The acid milk containing grape juice was prepared from natural grape juice, acid milk and sugar as raw materials, and the stability of the drink was studied. The following results were obtained. 1. The milk mixed with natural grape juice formed coagulated precipitate by coupling of the colloidal materials in the juice with the milk protein and the formation of precipitate was accelerated by pasteurization. 2. The pectin in natural grape juice was affected on the stability of the product, and the stability increased with decrease in the content of pectin. When the content of pectin in natural grape juice was lower than 2.5mg%, the precipitate was not formed in the drink containing 10 to 20% of the juice. 3. The acid milk drink containing the natural grape juice treated with pectinase, not formed precipitate by pasteurization at $85^{\circ}C$, for 20 minutes and can be preserved for long term.
