The present invention relates to refined sesame oil having a sesamin content of 1% by weight or more and showing no bitterness; a method for the production of refined sesame oil comprising using active carbon as an absorbent in a bleaching step; a method for the production of refined sesame oil comprising controlling a bleaching temperature in a range of from 5 to 70&#xb0; C. in a bleaching step with the use of activated clay active as an absorbent; and a method for the production of refined sesame oil comprising controlling a bleaching temperature in a range of from 5 to 70&#xb0; C. in a bleaching step with the use of activated clay of from 0.1 to 3% by weight active as an absorbent.

Sesame oil and process for producing the same

Fat-soluble trace constituents contained in plant tissues may be conveniently concentrated and/or purified by a method which involves extracting the fat-soluble trace constituent from a plant, to obtain an extract containing the fat-soluble trace constituent; adding a fatty acid ester to the extract, to obtain a mixture; and subjecting the mixture to molecular distillation. The method is particularly effective for the concentration and/or purification of fat-soluble constituents which are solids or viscous liquids at ambient temperature and ordinary pressure. The concentrated and/or purified fat-soluble trace constituent of a plant tissue prepared by the method may be combined with a food or drink to afford a food or drink product that contains the concentrated and/or purified fat-soluble trace constituent.
