식물유자원 중 참깨, 호두, 통밀, 미강을 원료로 하여 35 조건에서는 100rpm의 항온교반수조에서 1, 3, 6시간 단위로 추출하고, 8조건에서는 soxhlet extractor에서 1, 3, 6시간 단위로 각각 추출하여 추출방법 및 시간에 따른 최적 추출조건을 비교ㆍ분석하였다. 그 결과, 각 온도에서의 추출시간에 따른 추출율과 추출온도에 따른 추출방법의 변화는 추출율에 다소 영향을 미치는 것으로 확인되었다(p
To obtain the oil sesame, walnut, whole wheat, and rice bran were extracted for 1, 3, or 6 hr by a shanking water bath(35 and 100 rpm), and by soxhlet extractor(80) for 1, 3 or 6 hr, respectively. The highest yield of extracted oil was obtained from the walnut(63.07% weight) and the whole wheat showed the lowest extraction yield of oil(1.13% weight). Major fatty acids from the extracted oils were linoleic, oleic, and palmitic acid. The maximum contents of total phytosterol in sesame, walnut, whole wheat, and rice bran were 0.44, 1.57, 2.25, and 2.03(% weight), respectively. Besides, total tocopherol contents in sesame, walnut, whole wheat, and rice bran were maxima 3.42, 0.16, 2.92, and 0.07(% weight), respectively. From the extracted oils, structured lipids(SL) were synthesized by the interesterification reaction with conjugated linoleic acid(CLA) in a shanking water bath at 55. When the reactions(1:3 substrate molar ratio, extracted oil:CLA) were conducted for 24 hr, maxima 23.75 mol% of CLA incorporation was obtained from walnut oil and, in other cases, 16.28 - 19.15 mol% of CLA was found in the produced SL triacylglycerol molecules.
