![]() With the proper formulation, apple fibers can serve as polyphenol carriers, and thus the application as novel food additives can be considered.ĭietary fibers are well known for their health-promoting potentials such as lowering blood cholesterol and sugar levels and decreasing the risk of development of coronary diseases, hypertension, diabetes, obesity and gastrointestinal disorders. The results showed a negative effect of higher amounts of fiber (more than 2%) on the adsorption of polyphenols and the antioxidant activity of complexes. Polyphenol profile, antioxidant activity, inhibition of the α-amylase, color parameters, as well as the IR spectra, of the obtained complexes were assessed. Freeze-dried apple fiber/blackberry juice complexes were prepared with different amounts of fibers (1%, 2%, 4%, 6%, 8% and 10%) and a constant amount of blackberry juice. In the present study, the ability of apple fiber to adsorb blackberry juice polyphenols was examined. Fibers are recognized as efficient carriers of polyphenols and are often used in polyphenols encapsulation. ![]() Since they are very sensitive to environmental conditions such as the presence of light, oxygen and high temperatures, the application of such compounds is restricted. ![]() Blackberry polyphenols possess various health-promoting properties.
