  • 소시지 제조시 저장기간 연장을 목적으로 첨가되는 potassium sorbate(0.5%, 1.0%)와 nit-rite 감소를 위하여 첨가되는 ascorbic acid의 농도(0.5%, 10%)를 조정하여 오미자 추출물 첨가 소시지의 저장성과 잔존 이질산염 함량을 1$0^{\circ}C$와 3$0^{\circ}C$에서 저장하면서 관찰한 결과 온도에 관계없이 pH, 수분, 부수력, 염도, TBARS, 색차 관능검사 모두 저장기간이 경과함에 따라 낮은 값을 나태었다.(P<0.05),그러나 오미자 첨가 소시지의 잔존 nitrite 함량의변화는 대조구에 비해 낮은 값을 나타내어, 아질산염이 감소된 기능성 소시지의 개발 가능성을 시사하고 있다.그러나 pH의 감소로 인하 보수력의 저하로 조직감이 떨어져 소시지 제조시 첨가 농도를 0.5% 이하로 낮추는 것이 바람직하다고 사료된다.

  • In other to produce vinegar using Schizandra chinensis Ballon(omija), acetic acid bacteria(AAB) were selected from several conventional vinegars, and total 30 acetic acid bacterial strains were isolated. Among the isolated strains, a strain was selected from medium containing omija juice which showed the highest productivity of acetic acid. The strain was identified as Acetobacter sp. C5-1b. Optimum conditions for acetic acid production of Acetabacter sp. C5-1b were involved with 30t: of fermentation temperature and shaking culture. The acidity of culture medium was reached to 5.3% after 8 days shaking cultivation at 30℃.

  • Two compounds from Gomisin N and Gomisin A were isolated from the fruits of Schizandra chinensis Baillon. The highest extraction yield as 21.36% was observed in the ethanol extract, compared to the yield obtained form the water extract. The extraction yields of the single compounds were measured to be 0.13 and 0.014 Gomisin A and Gomisin N, respectively. Approximately, 90% of the growth of human stomach adenocarcinoma cancer cells was inhibited after adding 1.0 g/l of the ethanol extract. The growth of the human normal lung cell was limited to 24% after adding the ethanol extract. The water extract lowered the specific secretion of $TNF-\acute{a}$ and IL-6 from T cells, $10.3{\times}10^{-4}\;pg/cell\;and\;12.1{\times}10^{-4}\;pg/cell$, respectively, compared to the ethanol extracts. On the other hand, a treatment with the ethanol extract increased the specific secretion of $TNF-\acute{a}$ and IL-6 from human T cells, to $11{\times}10^{-4}\;pg/cell\;and\;14.3{\times}10^{-4}\;pg/cell$, respectively. The crude ethanol extract had the highest effect on the differentiation of human promyelocytic leukemia cells compared to the other extracts and Gomisin A and N. In general, the biological activities of the extracts gradually decreased as the purification process proceeded, which suggests that higher immunostimulatory activities can be maintained by adding the crude extracts of the fruits rather than by adding a single compound.

Effect of schizandra berry dregs and rice bran treatment on γ-aminobutyric acid (GABA) content enhancement in Pleurotus ostreatus (오미자박과 미강 첨가배지가 느타리버섯 자실체의 γ-aminobutyric acid(GABA) 함량에 미치는 효과)

  • This study was carried out to establish a cultivation technique for increasing the ${\gamma}$-aminobutyric acid (GABA) content in the fruit body of mushrooms by adding processed by-products. For the oyster mushroom 'Heucktari', addition of green tea powder, sea tangle powder, and green tea dregs resulted in very poor primordia formation, fruit body growth, and increased GABA. However, addition of 10% schizandra berry dregs and 1% rice bran to the basal substrate induced 100% and 10% increases, in GABA content in the fruit bodies compared to the control treatment without by-product, respectively. In addition, fruit body growth and primordia formation were greatly increased by these treatments. Therefore, GABA content was increased when the substrate was prepared by mixing an appropriate amount of schizandra berry dregs and rice bran.

  • Object : This study investigated the quality inspection of Schizandra chinensis (Turcz.) Bail distributed in Korea. Methods: To evaluate the quality of these herbal medicines, we carried out TLC pattern analysis, purity, loss on drying, ash, acid-insoluble ash, essential oil contents, dilute ethanol-soluble, water-soluble, ether-soluble extracts and HPLC analysis. Results : As a result, TCL pattern analysis of schizandrin and gomisin A showed Rf=0.64 and 0.74, respectively. To measured content of schizandrin and gomisin A, we quantitatively analyzed using HPLC. The average contents of schizandrin and gomisin A were detected to be 0.60 (${\pm}$0.02)% and 0.12 (${\pm}$0.004)%, respectively. Discussion : As a result of this study, we suggest that the minimum content of schizandrin and gomisin A should be 0.5% and 0.1%, respectively. We could suggest that the minimum of essential oil content should be 0.6 ml.

  • This study was carried out to examine the antioxidative, antimicrobial and nitrite scavenging effects of various solvent extracts and different solvent fractions from Schizandra chinensis RUPRECHT(Omija) seed. The results were as follows; The antioxidative activities using lard, soybean oil and linoleic acid were the highest in methanol, ethanol and methanol extract from omija seed, respectively. The free radical scavenging activity using DPPH method was the strongest in acetate fraction of methanol extract from seed. The methanol extract from omija seed had the strongest antimicrobial activities to L. plantarum, B. subtilis, E. coli and P. citrinum, while ethyl acetate extract had the strongest against S. aureus and S. typhimurium. The buthanol fraction from methanol extract had the highest antimicrobial activities, followed by B. subtilis, L. plantarum, E. coli, S. aureus and S. typhimurium. The nitrite scavenging ability was pH dependent, highest at pH 1.2 and lowest at pH 6.0. The buthanol fraction of methanol extract from omija seed had more effective nitrite scavenging ability than other fractions of extracts.
