  • 오미자 씨 오일의 화장품 소재로서 가능성을 평가하기 위해 GC와 GC/MSD를 사용하여 안정성 평가 및 성분 분석을 실시하였다. 그 결과 주요성분은 팔미틱산과 올레익산으로 나타났다. 오미자 씨 오일은 열에 의한 성분변화가 없고, 소재 자체의 안정성이 뛰어난 것으로 나타났다. 또한, DPPH(1,1-Diphenyl-2-picrylhydrazyl) 라디칼 소거능 실험을 통하여 항산화 효능을 측정한 결과 오미자 씨 오일이 마카다미아 오일과 올리브 오일에 비하여 높은 항산화 효능을 나타내었다. 콜라겐 합성능 또한 뛰어난 것으로 평가되었다. 따라서, 오미자 씨 오일은 화장품 소재용으로 유용하게 활용될 수 있는 가능성을 가진 것으로 평가되었다.

  • Grape seed oil was extracted using different preparatory treatments as follows: (1) grinding, (2) grinding and roasting, (3) grinding and wet- roasting, (4) grinding, roasting, and wet-roasting, and (5) grinding, wet-roasting, and wet-roasting. The highest antioxidant activity was obtained from the sample with the method (2). Initial states of oxidation were similar except method (1) that showed more oxidized state, being P.O.V.8. Acid values were observed in the range from 1.42 to 1.89. The lowest acid value was found as 1.42 in method (1) and those of others were somewhat higher, indicating that heating process of roasting produced some free fatty acids. From the results of sensory evaluation, the best odor and taste were obtained from the methods (2) and (3). Repetitive procedure of wet-roasting, like method 5, caused some loss of flavor components and decrease in the sensory evaluation score. Addition of grape seed oil (method 2) to soybean and perilla oil at the level of 20% retained considerable antioxidant activities as much as 4.3 and 5 times, respectively, than 100% soybean or perilla oil stored for 12 weeks. When soybean or perilla oil was mixed with 20% grape seed oils, P.O.V. decreased to half of that of unmixed oils.

  • 콩은 전 세계 시장의 48%를 차지하는 중요한 유료작물이다. 콩 종자를 구성하는 양적인 부분과 질적인 부분의 개선은 콩 육종 목표의 중요한 부분이다. 단백질함량과 종실의 크기는 두부와 콩나물의 질을 평가하는 중요한 특성이다. 따라서 본 연구는 콩에서 종실의 크기와 단백질 및 oil 함량을 조절하는 양적형질유전자좌(QTLs)를 확인하기 위하여 실시하였다. 시험재료로는 큰올콩과 신팔달콩을 교배한 후 $F_2$유래 $F_10$세대의 RIL을 이용하였으며, 이를 바탕으로 종실의 무게와 oil 및 단백질 함량과 관련된 QTLs를 탐색하였다. 종실의 무게와 단백질 및 oil 함량의 협의의 유전력은 각각 0.8과 0.78 및 0.71을 나타내었다. 종실의 무게와 관련된 QTLs는 연관군 F, I와 K의 세 개의 독립적인 QTLs를 확인하였다. 단백질함량과 관련된 QTLs는 연관군 D1b, E, H, I와 L의 다섯 개의 독립적인 QTLs를 확인하였다. 그리고 oil 함량과 관련된 QTLs는 연관군 D1b, E, G, I, J와 N의 여섯 개의 독립적인 QTLs를 확인하였다. oil 및 단백질 함량과 관련된 QTLs는 연관군 D1b, E와 I에서 공통적으로 나타났다. 따라서 이들 주요 QTL은 콩 품종 육성과정에서 품질의 개선하기 위한 선발 마커로서 활용가치가 높은 것으로 판단된다.

For rate of change in length of fat and oil soaking, there was an increase in the order of pig fat, bio-diesel, grape seed oil, and water; in the case of olive oil it was destroyed within 56 days. For rate of change in mass, there was an increase in the order of bio-diesel, water, pig fat, grape seed oil, and olive oil. For relative motion elastic coefficient, there was a decrease in the order of olive oil, grape seed oil, and water. On the whole, pig fat, bio-diesel, and olive oil were shown to have the worst effect on low-strength mortar.

  • This study examined the contents of bioactive compounds and the biological activity of okra seed oil. Okra seed oil consisted mainly of linoleic acid (44.2%). The content of total phytosterols was 2.180 mg/g oil, with β-sitosterol being the highest (1.756 mg/g oil). The vitamin E content was 1.278 mg/g oil; the content of α-tocopherol was higher than γ-tocopherol. The total polyphenol and flavonoid contents were 2.463 mg gallic acid equivalent/g and 1.602 mg cathechin equivalent/g, respectively. The 2,2'-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid and α-α-diphenyl-β-picrylhydrazyl free radical scavenging activities were 15.297% and 22.265%, respectively, and the reducing power was 4.524 mg gallic acid equivalent/g. The okra seed oil inhibited 77.692% of the α-glucosidase activity. The present study showed that okra seed oil had a considerable amount of phytochemicals and exhibited biological activity. These results suggest that okra seed oil is a potential natural therapeutic for the management of metabolic syndromes.

  • To observe the propability as the frying oil and oxidative stability of red pepper seed oil, some physico-chemical tests of the oil were examined during 21 days storage period at 5$^{\circ}C$, 15$^{\circ}C$ and 30$^{\circ}C$, and AOM value determined and after heating the oil at 180${\pm}$5$^{\circ}C$ for 40 hours with or without antioxidants. The analysis storage stability of red pepper seed oil showed that the quality of storage group at 5$^{\circ}C$ was almost as good as fresh oil, and the storage group at 30$^{\circ}C$ showed certain degree of rancidity. Change of physico-chemical characteristic during storage were so small so that storage stability of red pepper seed oil was found to be good. AOM stability of red pepper seed oil was 7 hours which is lower than other vegetable oil, but the degree of stability grew greatly after adding phenolic antioxidants, such on TBHQ or PG. As for the chemical change after heating continuously for 40 hours, acid value, peroxide value and refractive index increased, but iodine value decreased as the heating processed. The fatty acid composition also showed the remarkable reduction of linoleic acid. The addition of antioxidants resulted in the delay of oxidation, the degree of which was greater in TBHQ than in PG.

  • Lotus seed(Nelumbo nucifera Gaertner), known as traditional medicine as an antifebrile, antipsychotic, and cantihypertensive agent, was analyzed the chemical composition of lipid and protein. The seed com posed of 12.2% moisture, 2.3% crude lipid, 19.5% crude protein, 61.3% carbohydrate, 2.1% crude fibre, and 4.1% ash. The lipid showed iodine value of 97.9 that is lower than that of soybean oil and sesame oil, and similar to peanut oil and cotton seed oil. The fatty acid composition of the oil were the highest in content of linoleic acid which occupied 58.3% and saturated vs unsaturated fatty acid was 20.9:79.1. Especially behenic acid content, 6.9%, was higher than other plant oils. Sixteen amino acids were detected in the protein from the seed and glutamic acid content was the highest as 4.5% in dehulled kernel. The portion of essential amino acid was 31.1%.

  • Objectives: The purpose of this study was to investigate the effectiveness and safety of ginseng seed oil in healthy subjects who have mild liver dysfunction. Methods: A randomized, double blinded, placebo-controlled trial was conducted. A total of 167 subjects visited Semyung University Hospital from July 1st, 2016 to June 10th 2017. Except for the 103 excluded subjects, 64 subjects were randomized into one of the two groups: an treatment group(n=33) and control group(n=31). Subjects were randomly given either ginseng oil seed capsules or indistinguishable placebo capsules(2 capsules per dose, twice per day). Laboratory tests(aspartate aminotransferase, alanine aminotransferase, gamma glutamyl transpeptidase, triglyceride, total cholesterol, high density lipoprotein-cholesterol, low density lipoprotein-cholesterol) were performed to evaluate the effectiveness after 6, 12 weeks of treatment. Vital sign, laboratory test were performed to assess safety at every visit. Results: There were no significant differences in efficacy between treatment group and control group. There were some adverse events with no significant difference in symptoms and frequency between treatment group and control group. Conclusions: Although the efficacy of ginseng seed oil was not proved, ginseng seed oil did not worsen liver function and proved its safety. More study of ginseng seed oil and clinical trials are necessary to increase the usefulness of above-ground parts of ginseng.

  • Sesame (Sesamum indicum L.) seeds contain abundant oil and antioxidative lignans related to the seed quality. To evaluate the potential effects of drought stress on the chemical composition of sesame seeds, eighteen cultivars were imposed water-deficit condition by withholding irrigation during 15 days at podding and maturing stage, compared with well-watered plants as control in seed yield and chemical composition. Drought treatments showed great decrease of seed yield with not affecting seed weight. The contents of sesamin and sesamolin decreased while lignan glycosides inversely increased in response to drought stress. Oil content was not significantly changed by drought treatment in spite of its slight decrease. In case of fatty acid composition, there were significant differences in increase of oleic acid while inverse decrease of linoleic acid under drought stress condition. These results demonstrate that the chemical composition of sesame seed may be modified with drought stress. In particular, the increase of sesaminol glucosides with strong antioxidative activity was observed.
