Handbook on Natural Pigments in Food and Beverages

Ralf Schweiggert is the Head of the Institute of Beverage Research and Full Professor (W3) of the Chair of Plant Food Technology and Analysis of Geisenheim University. The main research interests of his workgroup are plant pigments, e.g., the elucidation of their structure, their stabilization for food applications, their antioxidant activity, and their bioavailability in humans. He has conducted several research stays at the Universidad de Costa Rica and the Ohio State University. His research and Ph.D. thesis was awarded the Baumann-Gonser-Research Award, the research award of the German Association for Quality Research, and the Professor Wild Award of the University of Hohenheim.
