This study was conducted to investigate the changes of pH, TBA, meat color and sensory evaluation on duck meat fed supplemental Bamboo vinegar during storage period at 4$^{\circ}C$ . Experiment animals (five-wk-old, Cherry Valley F$_1$, 100 chicks) were randomly assigned in four treatment groups. Treatments were control, 1%, 2% and 4% based on Bamboo vinegar addition. There was no PH difference in breast meat between groups on day 1 of storage, while pH of bamboo vinegar supplemented group was sustained hi호 after 3 days. TBA values of Bamboo vinegar treated groups were significantly lower than control group (P<0.05) and were steady change during storage. The color value in lightness no difference between groups during the storage. The control was significantly increased in 6 d and 9 d, while the bamboo vinegar treated groups no difference during storage. The redness and yellowness in bamboo vinegar treatment were decreased in 3 d and 9 d storage. The decrease in yellowness was outstandingly observed in bamboo vinegar 1% and 2% treatment (P<0.05). The odor in terms of sensory evaluation was improved by supplemental bamboo vinegar treatment. The significant differences were observed on 1 d, 3 d and 6 d storage (P<0.05). The appearance of sensory evaluation of supplemental Bamboo vinegar treated groups (P<0.05) was significantly different in 1 d and 3 d storage. The results of this study indicate that the supplemental Bamboo vinegar 1% and 2% may improve meat quality during storage period in duck meat.

Carbonization characteristics of Indonesian bamboos were investigated using lab-scale tube furnace, in order to find optimum design temperature of a carbonizer for producing bamboo charcoal and vinegar. The bamboo samples used in this study are local bamboos from Damyang in Korea, Andong and Petung in Indonesia. Correlation of electric resistance, specific surface area and pH of bamboo vinegar with pyrolysis temperature has been investigated. Electric resistance of the charcoal increased for higher pyrolysis temperature the specific surface area was also increased as carbonization temperature got higher. Charcoal which has specific surface area of over $300\;m^2/g$ could be produced at $700^{\circ}C$. pH of bamboo vinegar was decreased for highter carbonization temperature and vinegar under pH 3 could be produced for all bamboo samples. In this experimental condition, it was found that lower carbonization temperature is better for producing bamboo vinegar of high quality, while higher temperature is better for obtaining bamboo charcoal with larger surface.

중국산 죽순대 (Phyllostachys pubescens)를 간이탄화로(400 - 500 ℃)에서 제탄하고 얻어진 죽초액에 대하여 그 특성을 검토하였다. 중국산 죽순대로부터 제조한 죽초액은 보매 비중 4.5, 유기산 함량 9.9%, pH 2.8, 용해타르함량 3.1%, 굴절률 13.1%를 나타내었다. 이들 죽초액의 구조 동정 및 정량 결과, acetic acid, 1-hydroxyl-2-propanone, methanol, 1-hydroxyl-2-butanone, propionic acid 등이 주요화합물로 국내산 죽순대 죽초액과 큰 차이가 없었다. 총 유기물 함량은 14.8% 이었으며 이중 유기산류 (acetic acid, formic acid, propionic acid, butanoic acid)는 9.0%로 전체 유기물 중 약 61%를 차지하였다. 페놀류와 중성류는 각각 0.8%와 4.5%로 전체 유기물의 약 6%와 31%를 차지하였다. 시판되고 있는 중국 재래식 죽초액의 경우 대부분의 물성치 및 유기물 함량이 낮은 것으로 보아 본 죽초액은 탄화 초기단계에서 포집하여 숙성시켰을 가능성이 높다고 생각되었다.

In this study, the chemical components and termiticidal activities of bamboo vinegar against subterranean termite were evaluated. Bamboo vinegar used in this study were produced from Mayan (Gigantochloa robusta Kurz.), Balcoa (Bambusa balcooa Roxb.), and Taiwan (Dendrocalamus latiflorus Munro). It was analyzed by gravimetric methods. Rubberwood (Hevea brasiliensis) was soaked for 24 h and tested against Coptotermes curvignathus Holmgren according to the Indonesian National Standard (SNI 7207-2014). The bamboo vinegar demonstrated antitermite activities against subterranean termite. Vinegar of 400℃ recorded higher total phenol and acid than that of 300℃. Results from this study suggest that the phenolic and acidic component of the bamboo vinegar contributed to 100% mortality rate of the termite, some wood weight loss, and a decrease in the termite feeding rate. These results strongly recommend that bamboo vinegar from D. latiflorus Munro is a potential environmentally friendly preservative.

This experiment was conducted to investigate the effect of the supplemental Bamboo vinegar on production and meat quality of broiler ducks for 35 days. One hundred broiler ducks were divided into 4 groups of 25 ducks. Dietary levels of bamboo vinegar 0%, 1%, 2% and 4% were added to experimental diets ot each of the groups. The wei핌t gain and feed intake of ducks f3d with supplemental bamboo vinegar significantly high compared to those of the control. The carcass rate of the ducks fed with supplemental Bamboo vinegar 1% and 2% were increased compared to that of control, but the ducks fed with 4% treatment was decreased in carcass rate. The lipid and cholesterol content of breast meat of the ducks f3d bamboo vinegar 2% and 4% were significantly decreased (P<0.05). The color values in redness and yellowness were increased by supplemental Bamboo vinegar. Palmitic acid of fatty acid composition in breast meat was decreased by supplemental bamboo vinegar groups, whereas linoleic acid was increased, this difference was especially observed in supplemental Bamboo vinegar 2% (P<0.05). The odor, appearance and taste of sensory evaluation were improved by supplemental bamboo vinegar, especially in supplemental bamboo vinegar 1% and 2% (P<0.05). The results of this study indicate that the supplemental bamboo vinegar 1% and 2% may improve the production and meat quality of broiler ducks.

담양군 죽순으로 제조한 죽순식초와 시판 과실식초의 이화학적 특성인 산도, 무기질, 아미노산, 플라보놀을 비교 분석하고 SBSE-GC/MS방법을 사용하여 향기성분을 분석하였다. 죽순식초의 산도는 4.49%로 제일 낮았으며 무기질 중 Na의 경우 8.36 mg/100 g으로 다른 과실식초에 비해 그 함량이 낮았다. 아미노산은 다른 시판 식초에 비해 tyrosine과 lysine의 함량이 높았으며 flavonol aglycone 중 quercetin이 3.29 mg/L 들어있었다. SBSE방법으로 향기성분을 분석한 결과 aldehyde류의 함량이 시판식초에 비해 높았으며 특이적으로 수면 유도물질로 알려진 oleamide가 처음으로 검출되었다.

In this study, a dye bath was made using a mixture of distilled water, pine needle extract and bamboo vinegar. Analysis and comparison of various functions of cotton fabrics dyed using bamboo charcoal and gardenia seeds in distilled water and in the dye bath mixture were done. The summary of the results is as follows. Comparing bamboo vinegar and the pine needle extracts, the bamboo vinegar had a higher antibacterial function. In the case of natural dyeing cotton fabrics using bamboo charcoal and gardenia seeds, the additional amount of dyestuff for optimization is 10 g and 20 g respectively per 1 liter of distilled water. The suitable dye bath mixture ratio of distilled water, pine needle extract, and bamboo vinegar considering functionality and economical efficiency of dyed fabrics is 4:3:3. By using the mixture made in this study as a dye bath, improved antibacterial function, deodorization, and colorfastness can be obtained more than distilled water alone.

Objective : Bambusae Caulis in Liquamen has been used by East Asian doctors who approved efficient clinical effects of it since the early stage of medical history. It is commonly used for lifestyle related diseases including stroke in recent days thanks to the increasing number of manufacturers. However, products from pharmaceutical companies as well as food companies are not classified as Bambusae Caulis in Liquamen but Bamboo vinegar. This study aims to discern disparate manufacturing process. Methods : In this study, original texts were searched to corroborate the correct method to produce Bambusae Caulis in Liquamen. It is essential to inspect the original texts thoroughly in the course of modernizing traditional knowledge. Result : Discrimination between the two substances starts from manufacturing process; Bambusae Caulis in Liquamen is made under the temperature of less then $170^{\circ}C$, containing mild fragrance and sweet taste, and the Bamboo vinegar over $170^{\circ}C$ upto $400^{\circ}C$, carrying strong smoky scent and acidness. Although some researches show conforming clinical actions of both products, still there is a possibility that closer clinical study would reveal their discrepancy. Conclusion : Current use of Bambusae vinegar needs speculation. Authenticity in proper manufacturing process can be attained through passed-on medical texts.

본 연구는 죽초액을 함유한 폼클렌징과 토너, 팩 사용에 따른 여드름 피부상태 개선을 주·객관적 평가를 통해 검증하고자 하였다. 연구 대상은 한국형 여드름 중등도 시스템에 의한 2등급 이상의 여드름 피부 해당자로 광주·전라 지역 고등학교 남·여학생 20명을 선정하였다. 실험 진행을 위해 대상자를 죽초액 함유 폼클렌징, 토너, 팩 사용군(실험군) 10명, 죽초액 비함유 폼클렌징, 토너, 팩 사용군(대조군) 10명으로 나누어 12주 동안 각각 폼클렌징과 토너, 팩사용하도록 하였으며, 그 결과는 다음과 같다. 객관적 측정값에 의한 피부개선 효과에서 실험군이 대조군에 비해 이마, 콧등, 왼쪽볼의 모공 감소와 피지 개선 정도가 크게 나타났으며(p<.001), 주관적 평가도구에 의한 피부개선 효과에도 실험군이 대조군에 전반적인 만족도가 높게 나타났다(p<.05, p<.001). 화장품 사용 만족도는 전체 값에서 폼클렌저, 토너, 팩 모두 실험군이 대조군에 비해 높게 나타났으며(p<.01, p<.001), 세부적으로 유용성에서 통계적으로 유의한 차이를 보였다(p<.01, p<.001). 이상의 결과 죽초액은 여드름 피부상태 개선에 효과적인 천연화장품 소재임이 확인되었다.
