Summary:

Cyclodextrin Chemistry covers the preparation of cyclodextrins and cyclodextrin derivatives (CDs), and their applications in industrial and non-industrial areas. An overall theme in the book is the screening of cyclodextrin glycosyltransferase (CGTase), the preparation of sugar-branched cyclodextrins and CDs, and the use of CDs for reconstructing various supermolecule systems. The specific content also includes preparation methods, spectroscopy techniques for CDs analysis, and potential applications in food packaging, nutrient fortification, medicine, cosmetics, textiles, chemicals, feed, agri
