New Insights on Quality, Safety, Nutritional, and Nutraceutical Properties of Honeydew Honeys from Italy

Honeydew honey is less studied than nectar honey, although it is characterized by peculiar nutritional properties. This is mainly due to its challenging production, which leads to easy counterfeiting and difficult valorization. This contribution aims to provide a comprehensive characterization of th...
