“…Thus, in the recent period authors have investigated the encapsulation of RF in different biopolymeric systems. For instance, particulate systems were proposed such as hydrogel microspheres based on proteins (Chen & Subirade, 2009 ;O'Neill et al, 2014) or sodium alginate (El-Ghaffar et al, 2012 ;Messaoud et al, 2016), dried polysaccharide carriers (de Farias et al, 2018 ;Prosapio et al, 2020), or water-in-water emulsions (Chen et al, 2019). Different macromolecular complexes such as inclusion complexes in cyclodextrins (Terekhova et al, 2011), protein-polysaccharide electrostatic complexes (Kurukji et al, 2016), β-lactoglobulinbased nanocomplexes (Madalena et al, 2016) or molecularly imprinted polymers (Mokhtari & Ghaedi, 2019), were also investigated.…”
