본 연구에서 트랜스 지방산 함량에 대한 기초자료를 수집하기 위하여 서울 지역에서 수거한 도넛류 28종, 빵류 18종, 냉동생지류 4종, 팝콘류 2종, 그리고 육가공품 중에서 햄류, 너겟류, 소시지류 및 베이컨류 각각 1종씩을 선택하여 총 8종류의 56종의 시료를 분석하였다. 도넛류, 빵류, 냉동생지 및 팝콘류는 chloroform-methanol(CM) 추출법에 의하여 조지방을 추출하였으며 햄, 소시지, 너겟 및 베이컨류의 육제품은 산분해법을 이용하여 조지방을 추출한 후 gas chromatography(GC)에 의해 트랜스 지방산 함량을 분석하였다. 도넛류의 총 지방중 트랜스 지방산 함량은 0-3.3%이며 베이커리에서 원료에 마가린과 버터가 많이 함유되어 있는 페스츄리의 트랜스 지방산 함량은 0.2-5.8%로서 제조시 제품성상과 제조회사에 따라 차이가 많이 났다. 냉동생지의 트랜스 지방산 함량은 0.2-6.3%로서 시료 간 가장 많은 차이를 나타내었으며 이는 수입산 냉동생지 사용여부에 기인된다고 사료된다. 팝콘류에서는 총 두 제품 중 한 제품에서는 검출되지 않았으며 또 다른 제품에서는 5.8%의 높은 트랜스 지방산 함유률을 나타내었다. 육가공품에서의 트랜스 지방산 함량은 햄류, 너겟류 그리고 소시류에서 각각 0.1%로 낮은 수준으로 조사되었으며 베이컨류에서는 트랜스 지방산이 불검출 되었다. Small amounts of trans fatty acids exist naturally in beef and dairy foods. Also, they can be produced in the process of partial hydrogenation to manufacture shortning or margarine. They can provide a better palatability and shelf life. According to the recently studies, trans fatty acids can raise health risk such as heart diseases and coronary artery diseases. They can also increase low-density lipoprotein (LDL) cholesterol and decrease high-density lipoprotein (HDL) cholesterol in the blood plasma, therefore increasing the risk of atherosclerosis and diabetes. The aim of this study was to determine total lipids and trans fatty acids (TFAs) content in processed foods and meat products. The analysis of trans fatty acids was performed in 28 samples of donuts, 18 samples of bakeries, 4 samples of frozen doughs, 2 samples of popcorns, and 4 samples of meat products (ham, sausage, nuget, and bacon). Total lipids in processed foods and meat products were extracted by chloroform-Methanol method and acid digestion, respectively. They were analyzed by gas chromatography using a SP-2560 column and flame ionization detector. The amounts of TFAs per 100 g of foods were 0-3.3% (0.74% on average) in donuts, 0.2-5.8% (1.18% on average) in bakeries, 0.2-6.3% (1.93% on average) in frozen doughs, and 0-5.8% in popcorns. Meat products such as ham, sausage, and nuget analyzed 0.1% of TFAs, respectively and trans fatty acids in bacon were not detected. As a result, the distribution of TFAs in processed foods was widely ranged from O% to 6.3% according to manufacturers and types of products, whereas the content of TFAs in meat products ranged from 0% to 0.1%.

To evaluate the improving effects of antioxidant activity, we observed antioxidant capacities such as electron donating ability (EDA), Ferric reducing antioxidant power (FRAP), inhibitory activity of xanthine oxidase (XO) and aldehyde oxidase (AO), and sensory characteristics on mixture of Smilax china L. root water extract added with water extract of fermented S. china L. leaf by Aspergillus oryzae (FSCL). Those contents of mixture with higher ratio of FSCL were proportionally high. And OD475 of mixture with higher ratio of FSCL was almost proportionally high (R2= 0.9850). Antioxidant capacities of EDA and FRAP of the mixture was higher than that of non-mixture. In addition, XO inhibitory activity (IC50) of A (1.19) was 59.80% higher than that of F (2.96), and the activity of mixture by the higher ratio of FSCL was proportionally low (R2 =0.9490). Taste acceptability of A was slightly higher than that of F, whereas that of C was highest. And color acceptability of 40.80% mixture was higher than those of A, F, and B. Overall acceptability of C and D was highest than those of others. Moreover, hot water extract of S. china L. leaf fermented with A. oryzae was maroon color, which looks like Puerh tea style, and mixture of S. china L. root extract added with hot water extract of S. china L. leaf was high acceptability of beverage. These results suggest that mixture of extract of S. china L. root and hot water extract of S. china L. leaf fermented with A. oryzae could improve antioxidant activities.

Anthocyanin pigment is extensively extensively distributed in fruit juices shich are popular to consumer owing to valuable components such as vitamin, mineral, fiber, enzymes etc. Anthocyanin is using for detecting adulteration adn quality factor of fruit juices. So, research on the stability of anthocyanin is actively progressing not only using natural colorants also improving quality of fruit juices. And anthocyanin have only recently begun to be regarded as biologically active substances as well as colrants. Morever, fruits such as pear, apple, grape, plum which are widely produced in Korea containing more anthocyanins than any other pigments. However major problem associated with the storage of anthocyanin is their unstability, caused by certain enzymes, pH, temperature, metal complex, copigments.
