In this study, the dyeing properties of Phellodendron amurense on cotton and silk fabrics were evaluated to establish a scientific database of dyeing methods using natural dyes with the ultimate aim of facilitating the practical use of these dyes. The optimal thickener and dyeing concentrations depending on the thickener type were identified when dyeing with P. amurense, and the fabric color, color fastness, and antibiosis were examined for various thickeners, fabrics, and mordants. The results were as follows.: The optimal concentrations of thickeners when dyeing on cotton and silk fabrics were CMC 3% (w/w), Mayprogum 7% (w/w), and Indalka 9% (w/w). The optimal concentration of P. amurense was 25% (w/w), irrespective of the type of thickener. To maintain the hue unique to P. amurense, thickening with Mayprogum or Indalka and mordanting with Al was effective for cotton, while thickening with Mayprogum or Indalka and mordanting with Al or thickening with CMC and mordanting with gallnut was effective for silk. The dry-cleaning fastness and abrasion resistance of cotton fabrics dyed with P. amurense were excellent at the 4-5 level. Gallnut was effective for washing fastness and perspiration fastness against color degradation, and FFC was effective for light fastness. The washing fastness, dry-cleaning fastness, abrasion resistance, and perspiration fastness of silk fabrics dyed with P. amurense were excellent at level 4, except for washing and perspiration fastness, and FFC was effective for the improvement of light fastness. Dyeing cotton and silk fabrics with P. amurense thus yielded antibiosis and excellent washing fastness.

The study that has been conducted is the consideration of the durability of dye, antibacterial activity, and deodorizing effects of cotton and silk textiles dyed with a botanical dying material that has been used in various ways over the years as Korean diet and folk remedies, the pomegranate. 1. The results of the K/S value of dying according to the types of mordants of textiles dyed with pomegranate extract the following have been discovered: The increase of K/S value of dying of the silk textiles appear to be higher than that of the cotton textiles. Next, silk textiles that have been treated with FeSO$_4$.7$H_2O$ appear to be at the highest. 2. The results of the color change measurement show a difference of color can be noticed according to the types of mordant. As opposed to those textiles that had been only scured textiles, all of the dyed textiles appeared to turn yellow. 3. Textiles that had been treated with $K_2$Cr$_2$O(sub)7 recorded the highest durability according to the colorfastness to light results. In the case of the cotton textiles colorfastness to washing, all appeared to show exceptional results of 3rd class or higher, excluding the textiles that had been treated FeSO$_4$.7$H_2O$. However silk textiles recorded relatively low classes of below 3rd to 4th class. For the colorfastness to washing of pollution, the results for both the cotton and silk textiles were excellent at class 4-5. The results of colorfastness to perspiration, colorfastness to rubbing, and colorfastness to dry cleaning showed comparatively exceptional results of 3rd to 4th class or higher when it came to dyed textiles. 4. According to the measurements of antibiosis, dyed textiles that had been treated with SnCl$_2$.2$H_2O$ appeared to show an exceptional bacterium decrease of approximately 70%. 5. According to the deodorizing measurements, dyed silk textiles appeared to have a higher deodorizing effect than cotton textiles. As for cotton textiles, those that had been treated with FeSO$_4$.7$H_2O$ and in the case of dyed silk textiles those that had been treated SnCl$_2$.2$H_2O$ recorded the highest deodorizing effect.

예로부터 옷감의 염료 및 식용색소로 사용되어 온 치자는 혈당 저하, 항 종양, 항 혈전, 혈관신생 억제, 항산화, 항균 등 다양한 생리활성이 있는 것으로 보고되고 있으나 치자의 아질산염 소거 작용이나 육제품에의 이용에 관한 연구는 미비하다. 본 연구에서는 치자의 아질산염 대체 효과와 항균활성 등 기능성을 살펴보아 치자의 다양한 생리 기능성이 부여된 건강 지향적 육제품 개발의 기초자료로 활용하고자 아질산염(50, 100, 150 ppm)과 치자 추출물(0, 0.25, 0.5%)의 첨가량에 따른 돈육 패티의 물리 화학적 품질특성을 평가하고 아질산염 잔류량과 저장성을 살펴보았다. 패티의 색도를 측정한 결과 치자 추출물의 첨가에 따라 명도(CIE $L^*$)와 적색도(CIE $a^*$)가 감소되는 반면 황색도(CIE $b^*$)가 증가하였다. 돈육 패티를 가열한 결과 치자추출물이 첨가되지 않은 control 군에서는 아질산 첨가량이 많을수록 가열감량이 작았으나, 치자 추출물 첨가에 의한 가열감량의 변화는 명확히 관찰되지 않았다. $4^{\circ}C$에서 6주간 저장 후 패티의 pH, TBARS 및 VBN을 살펴본 결과 치자 추출물 첨가량이 많을수록 pH가 낮은 경향이었으나, TBARS와 VBN은 변화가 없었다. 돈육 패티의 아질산염 잔류량은 저장기간이 길어짐에 따라 점차 감소하였으며, 치자 추출물 첨가량이 많을수록 잔류량이 낮았다. 저장 중 미생물 오염을 살펴본 결과 대장균은 검출되지 않았으며, 일반세균은 치자 추출물 첨가에 따라 감소하여 항균 작용을 위한 아질산염 사용의 대체효과를 보였다. 이상의 결과를 보면 돈육 패티 제조 시 치자 추출물의 첨가는 아질산염 잔류량을 감소시킴과 함께 저장시 항균성을 증가시켜 건강 향상 기능성 천연 소재로서 치자의 이용 가능성을 시사한다.

키토산은 오징어 내장유를 이용한 oil emulsion 중에서 분자량이 높을수록 항산화 효과가 큰 것으로 나타났다. 또한 키토산을 다량의 지방이 포함된 축유 소시지에 첨가하여 $10^{\circ}C$ 저장하면서 항산화 효과를 측정한 결과, 키토산을 분자량별로 0.20% 첨가하고 아질산염을 150 ppm 첨가하였을 경우와 아질산염을 15 ppm 첨가하였을 경우 모두 키토산의 분자량이 높을수록 항산화 효과가 큰 것으로 나타났다. 어떤 분자량의 키토산에 있어서도 첨가량이 증가할수록 항산화 효과는 크게 나타났다. 키토산의 전자공여능은 분자량이 크고 농도가 높아질수록 큰 것으로 나타났다. 본 실험의 결과 키토산의 항산화 효과는 분자량이 클수록 첨가량이 많을수록 우수하며, 특히 가열 처리시에 효과가 크게 나타났다. 그러나 키토산의 항산화 효과는 단독으로 항산화제로 사용하기에는 미흡하여 소시지와 같은 지방이 포함된 식품에 있어 다른 항산화제와 더불어 키토산을 첨가하면 어느 정도 보존성 및 산화방지에 큰 효과를 얻을 수 있을 것으로 사료된다.
