Traditional extraction methods of paint samples or textile samples for chromatographic analysis are often too aggressive. Often, not only fragile colours (dyestuffs) like carrotenoids (present in for example; annatto seeds and safflower floss) are destroyed during the extraction. Likewise coloured sugars could be lost or even transformed into another new molecule. Preserving these sugars by using a soft extraction technique could be extremely useful as the sugars could provide information about the original botanical or biological source, also provide information about how the dye or pigment was prepared or something about the environment in which the plant or insect/mollusk source existed.
In this new blog I will give you a glimpse into the CHARISMA project aswell as my experiences throughout the project. First of all let me propperly introduce you with the project.
