Ultrasonic assisted extraction of polyphenols from bayberry by deep eutectic supramolecular polymer and its application in bio-active film

Deep eutectic solvents towards green polymeric materials

“…173 Additionally, specialized applications, such as generating chitosan-based bioactive polymer films with improved mechanical and anti-plasticity properties, were achieved through SUPRADES (β-cyclodextrin as the HBA and maleic acid, lactic acid, and citric acid as HBDs) extraction of polyphenols from bayberry. 183 Here, the effect of ultrasound on the extraction of polyphenols was assessed and it was found to improve the mechanical properties of the chitosan-based film, including its anti-plasticity ability as well as adhesion property, which could enable its use in animal-tissue-based applications.…”

Green materials with promising applications: cyclodextrin-based deep eutectic supramolecular polymers

“…The DESP extracts including the polyphenolic compounds were further used as plasticizers for chitosan to prepare highly active green biofilms. 94…”

Recent Progress on Green New Phase Extraction and Preparation of Polyphenols in Edible Oil

“…DESP not only possesses the properties of DES as a multifunctional medium, but is also a medium for the efficient extraction and stable storage of biologically active components. Shi et al [110] prepared a DESP, which was composed of a supramolecular polymer β-cyclodextrin (β-CD) as the HBA and lactic acid (LA) as the HBD, in a ratio of 1:1 (w/w%), while ultrasound-assisted DESP extraction was used for the best extraction efficiency of polyphenolic compounds.…”
