Application of gum Arabic in the production of spray-dried chokeberry polyphenols, microparticles characterisation and in vitro digestion method
Due to its high content of phenolics, black chokeberry has been proposed as a health-promoting material, especially use of chokeberry extract as a food or pharmaceuticals. Chokeberry extract was spray-dried using gum Arabic as a carrier. The optimal conditions for the efficient microencapsulation of chokeberry extract using spray-drying technique h...

Peer seeds - rich source of antioxidants
During fruit processing, a large amount of solid residues such as seeds, remains underutilized. There is a need to find method for use of these by-products and to convert them into products with significant health, environmental and/or economic benefits. This study provides data about content of lipophilic antioxidants (carotenoids and tocols) and ...
