The present invention discloses the use of a lycopene coated with a water non- soluble thin film comprising amphiphilic protein polymer for coloring with red color, foods, pharmaceuticals or cosmetics having fat and/or oil contents higher than 5 %. The invention further discloses a process for the preparation of stable lycopene formulation comprising: (a) treating an isolated protein to form a protein in a molecular form; (b) dispersing lycopene in an aqueous solution comprising an isolated protein in a molecular form; (c) grinding said dispersion to form lycopene particle size of 1 to 10 µm forming an homogenized mixture comprising fine particles; and optionally (d) drying the homogenized mixture.

L'invention concerne l'utilisation d'un lycopène enrobé d'un film mince non soluble dans l'eau, comprenant un polymère de protéine amphiphile, pour la coloration en rouge de produits alimentaires, de produits pharmaceutiques ou de cosmétiques ayant des teneurs en graisses et/ou en huiles supérieures à 5 %. L'invention concerne en outre un procédé de préparation d'une formulation stable de lycopène, consistant (a) à traiter une protéine isolée de manière à former une protéine sous forme moléculaire ; (b) à disperser le lycopène dans une solution aqueuse comprenant une protéine isolée sous forme moléculaire ; (c) à broyer ladite dispersion de manière à former du lycopène d'une granulométrie de 1 à 10 µm, tout en formant un mélange homogénéisé renfermant des fines particules ; et, éventuellement (d) à sécher le mélange homogénéisé.
