This study is to investigate the effect on the quality and properties of bread affected by licorice extract addition. The measurements of the farinograph, extensograph and amylograph on dough are carried out. And the evaluations of volumetric changes during fermentation, shape of bread crumb, sensory test, firmness are obtained. The obtained results are as follows. 1. Proximate compositions of licorice extract are as follows: moisture 73.7%, crude protein 4.1%, crude lipid 2.8%, crude ash 1.4%. 2. Water absoorption, arrival time dough development time mechanical tolerence index and valorimeter value are increased but stability is decreased with the addition of licorice extract. 3. The resistance to extension is increased but extensibility is decreased with the addition of licorice extract. 4. The initial pasting and highest viscosity temperatures are not affected but the highest viscosity is steepy decreased over 1.0% addition of licorice extract. 5. The volume of dough during fermentation and specific volume of bread is decreased with the addition of licorice extract. 6. The grain of bread is to be rough and irregular and the firmness is increased with the addition of licorice extract. 7. The records of sensory test are decreased with the addition of licorice extract.

This study is aimed to investigate the skin thickness, plasma components, serum IgE level and antioxidant enzymes activities by mixtures of Cnidium officinale, Saururus chinensis, Houttuynia cordata and Glycyrrhiza uralensis on the allergic contact dermatitis of rat induced by 1-chloro-2,4-dinitrochlorobenzene (DNCB). Mixtures reduced the thickness of the skin and removed the dead skin cells compared to the skin of rats treated with DNCB alone. Also, these mixtures down-regulated the contents of lipid and IgE, and reduced the activities of superoxide dismutase and catalase. These results indicate that the mixtures significantly recovered the contact dermatitis induced by DNCB. In conclusion, it is thought that the mixtures could be useful for the allergic contact dermatitis.

In this study, we screened twenty four extracts of eight medicinal plants and three extracts of the commercial product for their antimicrobial and antioxidant properties. Ethanol and ethyl acetate extracts were found active where as aqueous extracts were little or no active. Extracts of Sophora flavescens, Salvia miltlorrhiza and Glycyrrhiza uralensis showed strong activity againsttested organisms and could be the potential antimicrobial agent. The increase of antimicrobial and antioxidant activities of formulations might be due to synergic effect. The results also indicated that the activity of bamboo salt and herbal products can be enhanced by making appropriate formulations.

Licorice, which has an extensive history of use as an herbal medicine, has been suggested to have oral health benefits. However, to date, no systematic study has been conducted on the preparation method of licorice extracts for oral health. In this study, licorice extracts prepared using water and ethanol were investigated for its ability to inhibit the biofilm formation of Streptococcus mutans. The licorice extract prepared with around 60% ethanol effectively inhibited the biofilm formation of S. mutans. Licorice extracted with 50% ethanol almost completely inhibited the biofilm formation at 1.5 g/L of licorice extract. This inhibitory activity was confirmed in a microplate assay and a flow cell system. Glycyrrhetic acid was extracted from licorice effectively with 60% ethanol concentration. The strong inhibitory activity of glycyrrhetic acid and the synergistic inhibition with glycyrrhizin on biofilm formation were suggested as major reasons for a concentration-specific extraction. These results suggest that licorice extract prepared using around 60% ethanol effectively inhibits the biofilm formation of S. mutans.

감초, 박하 및 오미자 알코올 추출물, 오미자 분말과 키토산을 첨가한 탁주의 저장성 및 품질증진 효과에 대해 조사하였다. 생균수와 효모수는 12일간 저장 후에 오미자 분말과 키토산 혼합 실험구에서 약간의 생육억제효과가 나타났으나 전반적으로는 이들 한약재 첨가에 따른 저장 중 미생물의 생육에는 큰 영향을 미치지 않았고 발효가 끝난 상태로 계속 유지되었다. 산화도는 저장 초기에 실험구간의 차이가 크게 나타나지 않았으나 12일간 저장 후에 오미자 추출물과 키토산 첨가 실험구에서 가장 낮은 TBARS 함량을 나타내었다. 현탁 안정도는 저장 기간 동안 오미자 추출물과 키토산을 첨가한 실험구에서 가장 안정한 현탁 안정도를 보였다. 당도의 변화는 전반적으로 큰 변화없이 안정되게 유지되었으며, 추출물을 첨가한 실험구가 무첨가구에 비해 높게 나타났다. 저장 중의 pH는 3.55와 4.04사이에서 큰 변화 없이 유지되었으며, 총산의 변화는 저장 후기에 오미자 첨가구에서 약간 높게 나타났다. 색도의 변화에서 명도, 황색토 및 적색도의 경우 저장 초기에 무첨가구에 비해 한약재와 키토산 혼합 첨가구가 높은 것으로 나타났다. 기호도를 평가한 결과 제조 직후와 저장 6일 후에서는 무첨가구, 오미자 분말과 키토산 첨가구 순으로 기호도가 높게 나타났으나 저장 9일 후에는 오미자 추출물과 키토산 첨가구, 감초 및 박하 추출물과 키토산 첨가구에서 기호도가 높게 나타났다. 따라서, 키토산과 오미자 추출물, 오미자 분말, 감초와 박하 추출물 첨가는 탁주의 기호도 향상과 저장성 및 품질 증진에 효과적인 것으로 사료된다.
