In this study, Yukwa(YU-G) was prepared by coating in syrup with water-soluble extracts of Gugija(Lycii fructus). The Yukwa samples were stored with PE film packing with air for 12 weeks at room temperature, after which the quality and shelf-life of the Yukwa were assessed. During storage, the moisture contents of YU-G were higher than those of the Yukwa due to being coated in syrup without water-soluble extracts of Gugija(YU-NG), whereas the instrumental textural hardness values of the YU-G were lower than those of the YU-NG. Color determination indicated that YU-NG and YU-G assumed a darker color after storage, becoming both redder and yellower. The peroxide and acid values increased abruptly in the YU-NG during storage, but increased slowly in the YU-G. During the 12 weeks of storage after preparation, the peroxide and acid values of YU-G remained at less than 40 meq/kg and 4 KOH mg/g, respectively. Thus, the experimental method of syrup coating with water-soluble extracts of Gugija rendered the YU-G fairly stable against fat rancidity. The YU-G evidenced generally higher overall acceptability than YU-NG when stored.

Objectives : This study investigated the hepatoprotective effect of herbal mixture including Lycii fructus (HML) in thioacetamide (TAA)-induced hepatotoxicity in mice. Methods : To confirm the liver protective effect, induced by TAA for 3 days injection at 100 mg/kg mice, HML were treated for 8 weeks at 300 mg/kg/day, 1000 mg/kg/day. Positive control was treated silymarin 50 mg/kg/day after TAA injection. The changes of mortality rate, clinical signs, organ weight, relative liver, blood chemistry and histopathological findings were analyzed after experiment. Results : Body weight gain was observed in all groups, but TAA treated group at 4th week and all treated groups decreased weight compared to the untreated group. As a result of organ weight measurement, organ weight gain due to hepatic injury was observed statistically significantly in TAA-treated group and TAA+Silymarin treated group, and the herbal mixture-treated group showed a tendency to decrease compared to the TAA treated group. Blood biochemistry showed that total cholesterol and very low density lipoprotein cholesterol decreased statistically in TAA+low-dose and high dose herbal mixture treated group compared to the TAA-treated group. Histopathological examination showed that liver abnormalities were not observed in untreated group, liver fibrosis was observed in liver injury with TAA treated and herbal mixture treated group. And, TAA+high dose herbal mixture group showed relaxation tendency on liver calcification compared to the TAA treated group. Conclusions : According to the above results, HML provided hepatoprotective effects on the hepatic injury by reduction of inflammatory responses.

The principal objective of this study was to evaluate the quality characteristics of mungbeanmook prepared with five different levels (0, 5, 10, 15, and 20%) of Gugija (Lycii fructus) infusion. We analyzed Hunter's color values, pH, texture characteristics, and perfomed sensory evaluation of mungbeanmook prepared with Gugija infusion. The pH levels of mungbeanmook ranged between 5.45 and 6.12 and did not show significant differences. As Gugija infusion concentration increased, the color lightness "L" value decreased, whereas redness color "a" value and yellowness color "b" values increased (P<0.05). With regard to mechanical texture properties of the mungbeanmook samples, as the Gugija infusion concentration increased, the scores of hardness, chewiness, and gumminess all significantly decreased (P<0.05) whereas there were no significant differences in springiness or cohesiveness. The results of the sensory evaluation showed that the score of the LFLT10 sample (10% Gugija infusion) was significantly higher than those of others in terms of taste, color, flavor, texture, and overall quality (P<0.05). Taken together, the recommended optimum level of Gugija infusion in mungbeanmook is 10% for sensory evaluation. Gugija infusion can be a useful approach to improving quality of mungbeenmook as a functional food.

The purpose of this study was to investigate the quality characteristics and descriptive analysis of Yanggaeng prepared with Lycii fructus extract (LD). LD were added in ratios (w/w) of 0 (C), 1.5 (LY1), 3.0 (LY2), 4.5 (LY3), and 6% (LY4), and then proximate compositions, physicochemical properties, and sensory evaluations of the Yanggaeng were measured LY1~LY4 samples showed higher contents of crude lipid, crude protein and crude ash as well as $^{\circ}Brix$ compared to control (p<0.001). pH and lightness (L) of samples decreased as the LD increased. With regard to the texture of Yanggaeng samples, the scores of hardness, adhesiveness, springness, and cohesiveness was significantly increased by the Addition of LD (p<0.05, p<0.01). For the descriptive analysis, ten panelist generated and evaluated 29 sensory attributes for the Yanggaeng, and there were significant differences among the samples for all 26 sensory attributes. For the descriptive data, principal component analysis (PCA) was performed to summarize the sensory characteristics of the Yanggaeng. The results of PCA showed that the positive attributes, e.g. savoury, were closely in relationship with LY2 and LY3. Form the findings, this study suggests that 3~4.5% addition of LD was effective for preparation of Yanggaeng in the aspects of the consumer acceptability.
