Abstract

The present invention relates to a sesame oil and a method for preparing the same. The present invention provides a sesame oil having high lignan and tocopherol contents by preparing the sesame oil using an extraction and fractionation technique using a supercritical fluid, and a method for preparing the same. Also, the present invention provides a sesame oil having high lignan and tocopherol contents and a low free fatty acid content by preparing the sesame oil using an extraction and fractionation technique using a supercritical fluid and deacidifying the sesame oil, and a method for preparing the same.

First claim

1 . Sesame oil having a lignan content of 7,800 ppm or more and a tocopherol content of 300 ppm to 700 ppm.

2 . The sesame oil according to claim 1 , wherein the sesame oil has an acid value of 4.0 or less.

3 . The sesame oil according to claim 1 , wherein the lignan comprises at least one selected from sesamin, episesamin, sesamolin, sesamol, sesamolinol, sesaminol, and episesaminol.

4 . The sesame oil according to claim 1 , wherein the tocopherol is γ-tocopherol.

5 . A method of preparing sesame oil, comprising:
extracting sesame seeds using a supercritical fluid to provide sesame extract; and separating the supercritical fluid from a mixture of the supercritical fluid and the sesame extract, wherein extraction of the sesame extract is performed at an S/F ratio of more than 0, and 30 or less.

6 . A method of preparing sesame oil, comprising:
extracting sesame seeds using a supercritical fluid to provide sesame extract; separating the supercritical fluid from a mixture of the supercritical fluid and the sesame extract; and removing free fatty acids by adding at least one free fatty acid removal agent selected from among magnesium silicate, magnesium oxide, and sodium hydroxide to the obtained sesame extract.

7 . (canceled)

8 . The method according to claim 6 , wherein extraction of the sesame extract is performed at an S/F ratio of more than 0, and 30 or less.

9 . The method according to claim 5 , wherein extraction of the sesame extract is performed at a pressure of 120 bar to 700 bar and at a temperature of 40° C. to 90° C.

10 . The method according to claim 5 , wherein separation of the supercritical fluid is performed at a pressure of 40 bar to 70 bar and at a temperature of 20° C. to 50° C.

11 . The method according to claim 5 , wherein the supercritical fluid is carbon dioxide.

12 . (canceled)

13 . The method according to claim 5 , further comprising:
obtaining a first sesame oil by primary fractionation of the separated sesame extract at an S/F ratio of more than 0, and 10 or less; and obtaining a second sesame oil by secondary fractionation of the separated sesame extract at an S/F ratio of more than 10, and 30 or less.

14 . The method according to claim 6 , comprising:
obtaining a first sesame oil by primary fractionation of the separated sesame extract at an S/F ratio of more than 0, and 10 or less and obtaining a second sesame oil by secondary fractionation of the separated sesame extract at an S/F ratio of more than 10, and 30 or less before removal of free fatty acids; and removing free fatty acids from the first sesame oil.

15 . The method according to claim 6 , wherein magnesium silicate or magnesium oxide is added in an amount of 0.5 wt % to 4.0 wt % based on the weight of the sesame oil or the sesame extract.

16 . The method according to claim 6 , wherein sodium hydroxide is added in an amount of 0.1 wt % to 0.4 wt % based on the weight of the sesame oil or the sesame extract.

17 . The method according to claim 13 , wherein the first sesame oil, has a lignan content of 15,000 ppm or more and a tocopherol content of 300 ppm to 700 ppm.

18 . The method according to 17 , having free fatty acids in an amount of 1.0 wt % to 3.0 wt %.

19 . The method according to claim 13 , wherein the second sesame oil has a lignan content of 3,000 ppm or less and has an acid value of 0 to 1.0.

20 . (canceled)

21 . (canceled)

22 . The method according to claim 6 , wherein extraction of the sesame extract is performed at a pressure of 120 bar to 700 bar and at a temperature of 40° C. to 90° C.

23 . The method according to claim 6 , wherein separation of the supercritical fluid is performed at a pressure of 40 bar to 70 bar and at a temperature of 20° C. to 50° C.

24 . The method according to claim 6 , wherein the supercritical fluid is carbon dioxide.
