Title:
METHOD AND APPARATUS FOR PRODUCING EPISESAMIN-RICH COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2007/037385
Kind Code:
A1
Abstract:
It is intended to provide a method and an apparatus for producing a composition containing episesamin at a concentration exceeding 50% by weight based on the total weight of sesamin and episesamin simply and in high yield. The method for producing a composition containing episesamin at a concentration exceeding 50% by weight simply and in high yield comprising the steps of converting at least a part of sesamin into episesamin by subjecting sesamin or a composition containing sesamin to epimerization and selectively crystallizing episesamin using the recrystallization method and the apparatus therefor are provided.
