Abstract
A steam stripping fraction of sesame seed oil with increased concentration of sesamin and episesamin is used in a molecular distillation process to obtain a fraction containing more than 70 weight % of sesamin and episesamin. The steam stripping fraction is preferably obtained by a steam stripping process wherein the temperature (t.degree. C.) of the sesame seed oil and the pressure (P mmHg) for the process are such that {(4.24.times.10.sup.3)/(9.41-log P)}-273 .ltoreq.t.ltoreq.280 and 0.5.ltoreq.P.ltoreq.20.
Claims2
A method of separating sesamin and episesamin, said method comprising the steps of blowing steam into a sesame seed oil by a steam stripping process to thereby collect a steam stripping fraction with an increased concentration of sesamin and episesamin, and of carrying out molecular distillation of said steam stripping fraction to thereby obtain a product fraction containing more than 70 weight % of sesamin and episesamin, said step of blowing steam being carried out under such conditions of the temperature (t.degree. C.) of said sesame seed oil and the pressure (P mmHg) for said process that:
- {(4.24.times.10.sup.3)/(9.41-log P)}-273.congruent.t.congruent.280
- and
- 0.5.ltoreq.P.ltoreq.20.
