The chemical characterization of natural organic substances is a
challenging and significant task in the cultural heritage field.
Indeed, these substances are involved in many aspects of ancient
societies, including diet, medicine, funera ryrituals, artistic works,
economic and technical activities.
Studying the chemistry of these materials is the only way to get
information about their exact nature and their origin, but also to
identify their degradation mechanisms in order to preserve them,
or to get information about their original state.
The diversity of their biological origins, the complexity of
their composition, their poor conservation state (for the oldest),
