Method for producing sophorolipid and sophorolipid-containing composition containing sophorolipid obtained by said method

摘要

PROBLEM TO BE SOLVED: To provide technology to give foamability to sophorolipid and to control foaming in order to use sophorolipid in fields where foaming is required, without deviating from being natural product and without increasing environmental burden.SOLUTION: The method for producing sophorolipid is characterized in that yeast is cultured in a culture medium containing a seed extract of Madhuca plant under aerobic conditions. The sophorolipid composition contains sophorolipid obtained by the above sophorolipid producing method, including saponins derived from Madhuca seed.
