Curculin ist ein sΓΌΓ schmeckendes Protein, das in den FrΓΌchten der einkeimblΓ€ttrigen malaiischen Pflanze Molineria latifolia (malaiisch Lumbah) aus der Familie der Hypoxidaceae vorkommt. Die PrimΓ€rstruktur besteht aus 114 AminosΓ€uren.cite-ref-1[1]
Curculin lΓΆst auf der menschlichen Zunge einen SΓΌΓgeschmack aus, wie auch die Proteine Thaumatin, Mabinlin, Brazzein, Monellin, Pentadin und Miraculin.cite-ref-bilal-2-0[2] Seine SΓΌΓkraft in Bezug auf Saccharose betrΓ€gt das 550-fache in 6,8%iger LΓΆsung.cite-ref-belitz-3-0[3] Der durch Curculin herbeigefΓΌhrte sΓΌΓe Geschmack hΓ€lt nur wenige Minuten an. AuΓerdem hat es die Eigenschaft, sauren Geschmack in einen sΓΌΓen Geschmack zu verwandeln und ist somit ein Geschmackswandler (engl. taste modifier).
