 The possibility of the rainbow hologram application on the chocolate surface is considered.We present experimental results ondiffractive microrelief application with different periods on the surface of various chocolate types, differing by the percentage of cocoa products.The diffraction efficiency and lifetime of the samples is analyzed.

Keywords: rainbow hologram, diffraction grating, chocolate, edible hologram, chocolate decoration
