The Amidothèque is a database gathering information on the structure, morphology, composition, and thermal properties of native starch granules from a large number of botanical sources. To select a specific starch, you can browse the global list or use the "Basic Search". The "Advanced Search" allows you to select starches according to several criteria. For each starch, you will find a general description with information on shape, size, allomorphic type and composition of the granules, including references and relevant links. Pictures, polarized light optical micrographs, scanning electron microscopy images and X-ray diffraction patterns are available for most specimens. The information and images of the database can be used freely but we request that you acknowledge the Amidothèque and mention its URL. For comments, suggestions, and corrections, or if you want to submit a new starch to the database, please contact us.
