“…Similar protection was observed in samples exposed to white light for 10 days (−20% vs. −80%). Sulfonylated polysaccharides, such as dextran sulfate and carrageenans, can also be used to encapsulate bilberry anthocyanins from acidic solutions (pH ≈ 3) with high efficiency and improved stability [ 64 , 65 ]. The binding of isotherms and HPLC analysis showed that the binding is selective of anthocyanins (the other phenols remaining in solution) and is stronger when the sulfonylation degree is higher.…”

Owing to their specific pyrylium nucleus (C-ring), anthocyanins express a much richer chemical reactivity than the other flavonoid classes. For instance, anthocyanins are weak diacids, hard and soft electrophiles, nucleophiles, prone to developing π-stacking interactions, and bind hard metal ions. They also display the usual chemical properties of polyphenols, such as electron donation and affinity for proteins. In this review, these properties are revisited through a variety of examples and discussed in relation to their consequences in food and in nutrition with an emphasis on the transformations occurring upon storage or thermal treatment and on the catabolism of anthocyanins in humans, which is of critical importance for interpreting their effects on health.

“…However, the relatively low stability and bioavailability of anthocyanins are the primary barrier to limit the wide and effective applications [9][10][11], raising up the importance of reducing the degradation of anthocyanins and controlling release. So far, encapsulation [12][13][14][15], composite [16][17][18][19] and group substitution [20][21][22][23][24] are the three main means used for anthocyanin stabilization. Some studies have been carried out on the adsorption of pigments by Fe 3 O 4 [25] and the stabilization of Fe 3+ [26,27].…”

Anthocyanins are a class of antioxidants extracted from plants, with a variety of biochemical and pharmacological properties. However, the wide and effective applications of anthocyanins have been limited by their relatively low stability and bioavailability. In order to expand the application of anthocyanins, Fe 3 O 4 /anthocyanin magnetic biocomposite was fabricated for the storage and release of anthocyanin in this work. The magnetic biocomposite of Fe 3 O 4 magnetic nanoparticle-loaded anthocyanin was prepared through physical intermolecular adsorption or covalent cross-linking. Scanning electron microscopy (SEM), Dynamic light scattering (DLS), Fourier-transform infrared spectroscopy (FTIR), X-ray diffractometry (XRD) and thermal analysis were used to characterize the biocomposite. In addition, the anthocyanin releasing experiments were performed. The optimized condition for the Fe 3 O 4 /anthocyanin magnetic biocomposite preparation was determined to be at 60 • C for 20 h in weak alkaline solution. The smooth surface of biocomposite from SEM suggested that anthocyanin was coated on the surface of the Fe 3 O 4 particles successfully. The average size of the Fe 3 O 4 /anthocyanin magnetic biocomposite was about 222 nm. Under acidic conditions, the magnetic biocomposite solids could be repeatable released anthocyanin, with the same chemical structure as the anthocyanin before compounding. Therefore, anthocyanin can be effectively adsorbed and released by this magnetic biocomposite. Overall, this work shows that Fe 3 O 4 /anthocyanin magnetic biocomposite has great potential for future applications as a drug storage and delivery nanoplatform that is adaptable to medical, food and sensing.

“…In our previous work (Klimaviciute et al, 2015) we maintained that only the charge-charge interaction was responsible for the formation of complexes between strongly negative sulfate groups of dextran sulfate and the flavylium cation. These results were in contrast with the formation of complexes between chondroitin sulfate and ATCs (Jeong et al, 2012) where authors suggested that, besides the electrostatic, also the hydrophobic interaction and intermolecular stacking play a significant role in complex formation.…”

“…A new approach to stabilizing ATCs is their introduction into a nanocarrier system. ATCs containing stable nanoparticles were obtained during complex formation between ATCs and chondroitin (Jeong & Na, 2012) or dextran (Klimaviciute, Navikaite, Jakstas, & Ivanauskas, 2015) sulfate. First of all, the charge-charge interactions between strongly negative groups of sulfated polysaccharide and the flavylium cation were responsible for the complex formation.…”
