  • Xylan과 xylanase의 효소반응 후 생성되는 xylooligosaccharide를 식품에 적용하기 위해 점도, 내열성 및 pH 안정성, 착색성, 수분보습력 등의 기본적인 물리화학적 특성을 조사하였다. 70bx xylooligosacchride의 점도는 $20^{\circ}C$에서 930cP, $60^{\circ}C$에서 90 cp로 설탕보다 높았으나, 다른 올리고당류보다는 약간 낮은 특성을 나타내었으며, pH $2.5{\sim}8.0$ 범위에서 $100^{\circ}C$로 1시간 동안 열처리한 후에도 전혀 분해되지 않고 안정하게 잔존하여 내열성과 pH 안정성을 가지고 있음을 알 수 있었다. Xylooligosacchride의 pH는 $5.0{\pm}0.1$로서 pH $2.5{\sim}4.0$에서는 그 착색성이 매우 낮았으며, pH가 증가할수록 착색성이 높아지는 경향을 보였으나, 식품가공에 영향을 미치는 수준은 아니었다. Glycine 1%가 함유된 아미노산 공존하에서의 착색성도 매우 낮았으며 pH에 따라 크게 차이를 보이지 않았다. 수분보습력을 조사하기 위하여 71일간 $25^{\circ}C$, 75% 상대습도에서 xylooligosacchride를 저장 후 측정한 결과 95% 이상의 중량을 유지하고 있어 28%가 감량된 설탕보다 수분손실이 훨씬 적어 수분보습력이 훨씬 큰 것을 알 수 있었다. 이러한 결과로 볼 때 xylooligosacchride는 식품에 사용하기에 적합한 물성을 가지고 있어 기능성 증진 효과를 나타내고자 하는 다양한 식품에 응용 가능할 것으로 판단된다.

  • The purpose of this study was to investigate the characteristics of macaroons prepared using natural color materials (Opuntia ficus-indica var. saboten (Re-N), mulberry leaf (Gr-N), pumpkin (Ye-N), and cocoa powder (Br-N)) and corresponding artificial food colorants (red (Re-A), yellow (Ye-A), green (Gr-A) and brown (Br-A)). The moisture content of macaroons prepared using natural color material was higher compared to the macaroons prepared using artificial food colorant. DPPH and ABTS radical scavenging activity was similar in both types of macaroons. Lightness and redness of Re-N, Gr-N, Ye-N, and Br-N macaroons were lower than Re-A, Gr-A, Ye-A and Br-A macaroons. Yellowness of Re-N was higher because of the browning reaction. The texture profile analysis revealed lower hardness when natural color powder was employed. In the sensory evaluation, overall acceptability was not significantly different between natural colored and artificial colored macaroons. As a result, macaroons with the natural color material were softer and showed higher antioxidative activity, however, organoleptic properties were not much different when compared with macaroons with artificial colors. Apparently, it is stated that more studies on the development of macaroons with more enhanced physical functionality and good taste using natural materials should be performed.

  • Wheat is the most abundant crop in the world, accounting for one third of the world's population diet. In Ukraine, wheat is in fact, in addition to its nutritional value, a national symbol of the state. Therefore, the main thesis on the development of modern plant growing in Ukraine is the reduction of costs and the introduction of innovative technologies. The quality of grain and seed depends on many factors, namely: agro-climatic conditions, sowing condition of the seed material, quality characteristics of the soil, yielding properties of seeds, pre-sowing seed treatment. etc. For this purpose, the photosynthesis and intensity of photosynthesis need to be limited to the width of the leaf and the height of the leaves by a smaller cut of the stem. It is extremely important to ensure that the head and side pagons of wheat are in good condition. All parameters are often secured by the technology of grain preparation before delivery. Prior to this technology, it is possible to introduce processing of the material in the form for the development of the material. This article presents the effectiveness of the use of infrared irradiation for the pre-sowing treatment of winter wheat seeds in Sekobra Research, Germany.

  • Spirulina is known to be more useful abroad than in Korea because it contains more protein than Chlorella, the same microalgae. In the past, sources of animal protein were diverse, but since it takes a long time to receive protein along with environmental pollution, we thought that spirulina could attract attention as a new protein source. In this study, application cases were analyzed in foods in the fields of acorn cake, tofu, dumpling skin, fish cake, white bread, pound cake, salad dressing, and yogurt and so on. As a result of centrally analyzing antioxidant and sensory evaluation, it was confirmed that the results were effective enough to develop products in tofu, dumpling skin, fish cake, and pound cake. It is thought that development of food in other fields will be possible if an additive amount that can match the consumer's preference is found by supplementing the mixing ratio. If it is used as a main raw material for existing food rather than as a raw material for health functional food, consumer preference can increase and quality can be further improved, and it can be suggested as a good alternative for an aging society.

  • Salidroside is a major phenolic glycoside of Acer tegmentosum (Aceraceae) and known to be a hepatoprotective compound. Extraction conditions are one of the most important factors to save time and cost from an economic point of view. For this reason, this study was conducted to optimize the extraction condition for maximum yield of salidroside. For optimization, three extraction factors such as ethanol concentration (%), extraction temperature (℃), and solvent to material ratio (mg/mL) were tested and optimized for maximum yield of salidroside using response surface methodology (RSM). The optimal condition was obtained as an ethanol concentration of 53.4%, an extraction temperature at 67.11℃ and a solvent to material ratio (mg/mL), 195.55 mg/ml. The salidroside yield under optimal conditions was found to be 1.59 mg/g dried samples, which were well-matched with the predicted value of 1.56 mg/g dried samples. These results will provide useful information about optimized extraction conditions for the development of salidroside as hepatoprotective therapeutics.

  • The anti-metastatic activity of water extract of Samguikoeuitang (WSGKE) consisting of Ginseng Radix, Angelicae Radix, Sophora flavescens and Coicis Semenwas examined. Ethanol extract of Samguikoeuitang (ESGKE) showed significant cytotoxicity against colon 26-M3.1 carcinoma cells, while WSGEK did not. However, WSGKE significantly increased the production of IL-6 and IL-12 in thioglycollate-induced macrophages from Balb/c mice, whereas ESGKE did not. WSGKE significantly increased natural killer (NK) cell cytotoxicity against effecter YAC-1 cells in an Effecter cells/Target ratio dependent manner. Also, WSGKE significantly suppressed lung metastasis after i.v. injection of colon26-M3.1 carcinoma cells. Inhibitory effect of WSGKE on lung metastasis totally abolished in NK cells-deficient mice by treatment with anti-asialo GM1 serum. In addition, the combination treatment of cisplatin and WSGKE (100 ${\mu}g$/mouse) prolonged the lifespan of mice inoculated by colon26-M3.1 cell. These findings suggest that WSGKE can inhibit lung metastasis and prolong life span via immunological enhancement as a Biological Response Modifier.
