The present invention relates to a coating wax for a food product, comprising at least one block copolymer composed of at least one block of polymer (A) resulting from the polymerization of at least two, identical or different, monomers (MA), which are derived from long-chain fatty acids, said long chain comprising from 14 to 34 carbon atoms and of at least one block of polymer (B), different from (A), resulting from the polymerization of at least two, identical or different, monomers (MB), which are derived from short-chain fatty acids.La presente invención se refiere a una cera de revestimiento de un producto alimenticio, que comprende al menos un copolímero de bloques constituido de al menos un bloque de polímero (A) surgido de la polimerización de al menos dos monómeros (MA), idénticos o diferentes, derivados de los ácidos grasos de cadena larga, la cadena larga comprende de 14 a 34 átomos de carbono y de al menos un bloque del polímero (B), diferente de (A), surgido de la polimerización de al menos dos monómeros (MB), idénticos o diferentes, derivados de los ácidos grasos de cadena corta.
