METHOD FOR PRODUCING CIS-LYCOPENE-CONTAINING COMPOSITION, METHOD FOR PROMOTING ISOMERIZATION OF LYCOPENE AND CATALYST FOR ISOMERIZING LYCOPENE

摘要

[Problem] The present invention addresses the problem of efficiently isomerizing lycopene, more specifically, shortening a step for isomerizing lycopene.[Solution] As the results of intensive studies, the present inventor found that lycopene can be isomerized within a short period of time by isomerizing a mixture of a lycopene-containing material with an isothiocyanate-containing material. The method according to the present invention for producing a cis-lycopene-containing composition involves at least isomerization. In the isomerization step, a mixture comprising a lycopene-containing material with an isothiocyanate-containing material is isomerized.
