  • The following study is the result of herbal teas puffed at different temperatures between $140{\sim}220^{\circ}C$. There was change of single breadth that some carbonization occurs according to rise of processing temperature and crude ash content rises relatively, and crude protein and crude fat content had hardly changed and moisture content decreased. The solid elution rate of the herbal teas appeared by 0.18~0.27% (w/w), it increased as puffing temperature rises. The reason for the increase in solid elution rates is due to the breakage of cross bridges between the raw materials in the herbal tea which are carbohydrates, proteins, lipids and etc. after treatments of physical changes rather than chemical ones. Benzopyrene content happened difference in B(${\alpha}$)P content according to processing temperature, raw material by 0.18~0.24 ppbs.

  • Kiwifruit pulp was separated into insoluble pulp and serum by centrifugation at 14,000 rpm for 10 min. The serum portion was concentrated at $30{\sim}50mmHg\;and\;50{\sim}55^{\circ}C$ with aroma recovery. Vapor generated at the early stage of vacuum evaporation was condensed and taken as aroma fractions: $E-I\;(0{\sim}10%),\;E-II,\;(10{\sim}20%)$. The volatile flavor compounds in kiwifruit pulp were collected by dynamic headspace technique and analyzed by GC and GC/MSD. The yield of serum separated from kiwifruit pulp was 70.1% and insoluble pulp fraction contained aroma compounds more than that of the serum. Twenty-six aroma compounds, including (E)-2-hexanal and ethyl butanoate were detected. The efficiency of the aroma recovery was reduced as the recovery time was extended, as indicated by the less peak numbers and kiwifruit areas of aroma fractions.

  • Effects of antimicrobial herbs on growth of tactic acid bacteria were investigated to extend shelf-life of Dongchimi, kimchi made with radishes and spices. Marta rosemary, among eight foreign and domestic herbs, showed strongest antimicrobial activity against seven kinds of lactic acid bacteria. Spices such as spring onion, garlic, and ginger showed no antimicrobial activity against lactic acid bacteria. During fermentation of Dongchimi for 6 days at $35^{\circ}C$, addition of marta rosemary inhibited acid formation, maintaining optimal pH of 3.8-4.2 throughout fermentation period, while no inhibitory effect was observed from Sambaekho (Saurus chinensis), pepper mint, and stevia. Results show shelf-life of Dongchimi was extended by addition of marta rosemary, which controlled over-production of tactic acid by inhibiting bacterial growth.

  • The nutraceutical role of fermented omija (Schizandra chinensis) beverage (FOB) was determined through the analysis of fibrinolytic and alcohol metabolizing activities, nitrite scavenging activity, and angiotensin converting enzyme and $\alpha$-glucosidase inhibitory effects. Firstly, FOB increased fibrinolytic activity in a dose-dependent manner and indicated angiotensin converting enzyme inhibitory activity of 94.8% at 20% FOB (0.6 mg/mL). In addition, the inhibitory activities of FOB on $\alpha$-amylase and $\alpha$-glucosidase were determined to be 100% at 100% FOB (3 mg/mL) and 49% at 60% FOB (1.8 mg/mL), respectively. Nitrite scavenging activity of FOB was about 96.1%, 72.3%, and 68.3% on pH 1.2, 3.0, and 6.0 at 100% FOB, respectively. To determine influence of FOB on alcohol metabolism, the generating activities of reduced-nicotinamide adenine dinucleotide (NADH) by alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH) were measured. Facilitating rate of ADH activity was 70.3% at 50% FOB, but ALDH activity was not affected. These results revealed that FOB has a strong alcohol metabolizing activity, and fibrinolytic and nitrite scavenging activities and exhibits the angiotensin converting enzyme, $\alpha$-amylase, and $\alpha$-glucosidase inhibitory activities.

  • This study aimed to compare total phenolic, total flavonoid, and vitamin C contents, antioxidant capacities, and sensory characteristics of jangachi made from green kiwifruit (Actinidia deliciosa cv. Hayward) and golden kiwifruit (A. chinensis cv. Hort16A), which were cured with doenjang and kochujang. Golden kiwifruit had higher total phenolic, total flavonoid, and vitamin C contents, and antioxidant capacities than green kiwifruit. Jangachi of both cultivars of kiwifruit had generally higher total phenolic and flavonoid contents, and antioxidant capacities than fresh kiwifruit. Doenjang jangachi of kiwifruit had higher total phenolic contents and antioxidant capacities than kochujang jangachi. Jangachi made from golden kiwifruit cured with kochujang, following pretreatment with sugar solution, had the highest overall quality on sensory evaluation among jangachies tested herein. Together, our findings suggest that kiwifruit jangachi may serve as a good dietary source of phenolics and antioxidants.

  • Objectives : The current treatment regimens for patients with nephrotic syndrome due to membranous nephropathy(MN) are based on steroids or immunosuppressive therapy with the aim of reducing proteinuria and improving outcome. Although these treatments attenuate the deterioration of renal function in MN patients, it has been suggested that all are burdened by significant toxicity. Therefore, more specific and less toxic therapies are needed. This study was to evaluate the effects of Coptidis Rhizoma Extract(CRE) on the MN induced by cBSA in mice. Methods : Mice were divided into 4 groups. One group named for 'Normal' was injected with a saline solution not to be immunized. The rest groups were treated as follows; After mice were immunized with 0.2 mg of cBSA and Freund's complete adjuvant one time every two weeks for 6 weeks, they received intra-peritoneal injection of 10 mg/kg of cBSA daily for 4 weeks. Also, they were divided into 3 groups. The first named for 'Control' was not given CRE. The second for 'CRE-250' was given oral administration of 250 mg/kg of CRE daily for 4 weeks. The third for 'CRE-500' was given 500 mg/kg of CRE. All of mice were sacrificed 4 weeks after the first immunization. We measured a body weight and 24hrs proteinuria as well as serological analysis. The morphologic changes of renal glomeruli were also observed with a light microscope and an electron microscope. Results : The levels of 24 hrs proteinuria, triglyceride, IgG, IL-6 were significantly decreased in both CRE groups. And the level of IgM was significantly decreased in CRE-250 group. In histological findings of kidney tissue, thickening of GBM and deposition of electron-density were consideraly decreased in both CRE groups. Conclusions : The present study suggests that CRE is highly effective when treating mice with MN induced by cBSA. More clinical data and studies are to be done for efficient application.

  • The antioxidant and antimicrobial activities of pork patties supplemented with medicinal herb extract mix were investigated. The medicinal herb extract powder was mixed at a ratio of 48.5:48.5:3.0 for Morus alba L, Lonicera flos, and Coptis chinensis, respectively. The pork was prepared and supplemented with medicinal herb extract mix (0, 0.5, 1, or 2%) and the antioxidant and antimicrobial activities were tested during storage at $4^{\circ}C$. The pH value decreased during cold storage at $4^{\circ}C$ for allsamples, however the pH of samples supplemented with herb extract mix rapidly decreased by days 5 and 10 ($p{\leq}0.05$). The total phenol content in the pork patties with herb extract mix was higher than in the control patties. The ABTS+ radical scavenging activities increased with increasing concentrations of herb extract mix from 0.5% to 2%. In addition, pork patties supplemented with herb extract mix showed an approximately 1 decimal reduction in total aerobic counts. Therefore, the addition of herb extract mix into pork patties increased the antioxidant activity and slightly improved the antimicrobial activity of pork patties during cold storage. However, the levels of added medicinal herb extract mix should be considered prior to its use in order to maintain proper sensory acceptance.
