본 연구에서는 폐기되는 성게 껍질을 이용한 생분해성 필름소재를 개발하고자 gelatin을 첨가한 복합필름 및 항산화, 항균성을 부여하기 위해 아까시 꽃 추출물(RFE)을 첨가한 필름을 제조하였다. 그 결과 gelatin 비율이 증가함에 따라 성게 껍질 필름의 인장강도가 증가하였고 신장률이 감소하였으며, 성게 껍질과 gelatin을 8:2 비율로 첨가하였을 때 최적의 물성을 보였다. 또한, 필름에 RFE를 첨가함에 따라 인장강도는 감소하였으나 신장률과 필름 투습도는 증가하였다. RFE 함유 성게 껍질 필름의 ABTS, DPPH 라디칼 소거능 측정과 디스크 확산법을 이용하여 항산화 및 항균 능력을 측정하였는데, RFE 농도가 증가함에 따라 항산화, 항균 능력이 향상하였다. 따라서 본 연구 결과, RFE를 첨가한 생분해 성게 껍질 필름은 적절한 물성과 함께 항산화, 항균 능력이 있기에 가공식품의 저장성을 증대시킬 수 있는 기능성 포장 소재로의 활용이 가능하다고 판단된다. Sea urchin skeleton (SUS) generated from production of sea urchin eggs was used as a biodegradable film base material, and its composite film with gelatin was prepared. In addition, Robinia pseudoacacia flower extract (RFE) was incorporated into the film-forming solution to provide antioxidant and anti-microbial activities. The tensile strength (TS) of the SUS/gelatin composite films increased with increasing gelatin content, whereas elongation at break (E) decreased. Among the composite films, SUS/gelatin film at a ratio of 8:2 (w/w) exhibited the most desirable TS and E values. Furthermore, SUS composite film containing RFE showed a reduced TS and increased E compared to the control film. Based on 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) and 2,2-diphenyl-1-picrylhydrazyl radical scavenging assays and disc diffusion results against growth of Listeria monocytogenes, antioxidant and anti-microbial activities of films increased with increasing RFE concentration. Consequently, SUS composite film containing RFE showed proper physical properties as well as antioxidant and anti-microbial activities. These results indicate that SUS can be used as a film base material while the SUS composite film containing RFE can be utilized as active packaging.

옥수수의 습식 분쇄 공정 중 나오는 부산물인 옥피로부터 옥피 단백질(CFP)을 추출하였다. 다양한 가소제와 가교제를 첨가하여 CFP 필름을 제조한 후, 필름의 물성을 측정하였다. 본 연구에서 사용된 가소제와 가교제 중, 2 g fructose와 0.03% cinnamaldehyde를 첨가한 필름이 가장 좋은 물성을 가졌다. 또한 여러 농도(0, 0.5, 1.0, 1.5%)의 녹차 추출물(GTE)을 첨가한 CFP 필름을 제조하였다. GTE의 농도가 증가함에 따라 CFP 필름의 인장강도, 수분 용해도, 불투명도는 증가하였고, 반면에 신장률과 필름의 수분투과도는 대조구에 비해 감소하였다. GTE 첨가한 CFP 필름의 항산화성은 DPPH 소거능으로 측정하였는데, GTE 농도가 증가함에 따라 증가하였다. 그리고 E. coli O157:H7, L. monocytogenes, S. aureus 에 대한 항균성 실험을 한 결과 또한 GTE 농도가 증가함에 따라 증가하였다. 따라서 본 연구 결과, GTE 첨가는 CFP 필름의 항산화, 항균효과를 가져다 준다고 판단된다. Corn fiber protein (CFP) was extracted from corn wetmilling by-product, corn fiber. CFP films containing various plasticizers and cross-linking agents were prepared and their mechanical properties were determined. Among the plasticizers and cross-linking agents used in this study, the CFP film containing 2 g fructose and 0.03% cinnamaldehyde had the most appropriate physical property. In addition, the CFP films containing green tea extract (GTE) were prepared by incorporating different amounts (0, 0.5, 1.0, 1.5%) of GTE into the film-forming solution. Tensile strength, film solubility, and opacity of the CFP films increased with the addition of GTE, whereas elongation and water vapor permeability of the CFP/GTE films decreased compared to those of the control. The antioxidant activity of the CFP/GTE film was determined in terms of 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity. As a result, antioxidant activity of the films increased with increasing GTE concentration. Furthermore, antimicrobial activity against Escherichia coli O157:H7, Listeria monocytogenes, and Staphylococcus aureus increased with increasing GTE concentration. These results indicate that the incorporation of GTE could enhance antioxidant and antimicrobial activities of the CFP films.

This study was designed to compare the anti-inflammatory effects of herbal decoction and fermented herbal decoction in Hwangnyeonhaedok-tang (Huanglian fiedu-tang; HHT). Methods : The effects of HHT and FHHT on anti-inflammation were measured by production of NO and pro-inflammatory cytokine productions including TNF-${\alpha}$ and IL-1${\beta}$, IL-6 in LPS induced RAW 264.7 cells. Results : 1. Cell viability in three doses of HHT extract (0.01, 0.05 and 0.10 mg/ml) and two doses of FHHT extract (0.01, 0.05 mg/ml) was more than 70% and 80% each. 2. In RAW 264.7 cells, LPS displayed significant stimulatory effects on the production of NO. However, both HHT, FHHT showed significant inhibitory effects on the production of NO. 3. Pre-treatment by HHT in a various concentrations (0.01, 0.05, 0.10, 0.50mg/ml) reduced the elevated production of TNF-${\alpha}$, IL-1${\beta}$, IL-1${\beta}$ mRNA, IL-6 mRNA. More than 0.05mg/ml concentrations of HHT reduced the production of IL-6. And TNF-${\alpha}$, IL-1${\beta}$ level of mouse serum reduced in a various dose(0.1, 0.5, 1.0g/kg). 4. Pre-treatment by FHHT in a various concentrations (0.01, 0.05, 0.10, 0.50mg/ml) reduced the elevated production of TNF-${\alpha}$. More than 0.05mg/ml concentrations of FHHT reduced the expression of TNF-${\alpha}$ mRNA. 0.1, 0.50mg/ml concentrations of FHHT reduced the production of IL-6. And IL-1${\beta}$ level of mouse serum reduced in a various dose(0.1, 0.5, 1.0g/kg). Conclusions : These results indicated that both HHT and FHHT could have anti-inflammatory capacity by inhibiting the production of NO and cytokines in vitro. But HHT has more strong anti-inflammatory effects than that of FHHT in broad outlines.
