Compositions for stabilizing an isothiocyanate

The present invention relates to stable compositions comprising an isothiocyanate. It also relates to methods for stabilizing an isothiocyanate. According to the invention, sulforaphane is stabilized in the presence of fatty acids. Compositions prepared by mixing sulforaphane with certain amounts of a fatty acid or a mixture of fatty acids exhibit a stabilizing effect with respect to residual sulforaphane. It was found that such compositions can maintain sulforaphane, as expressed by % w/w, more effectively, i.e. stabilize it, compared to neat sulforaphane, under certain storage conditions. This facilitates the distribution of sulforaphane as a component to be used for industrial purposes, for example in the preparation of various products, dietary supplements, food additives, pharmaceuticals, nutraceuticals, cosmetics etc, because it makes long-term storage easier and efficient. No complex techniques are required for the stabilization, such as encapsulation or complexation, neither extremely low temperatures.
