Abstract

Organosulfur compounds can be used in complexes with carotenoids for effecting a bathochromic shift in the absorption bands of carotenoids in the UV/vis spectrum. Carotenoid formulations comprising these complexes, a process for preparing these formulations and their use in the food, cosmetics and pharmaceutical sectors are described.
