In recent years, anthocyanins, natural dyes, have promoted great scientific and technological interest. Their intrinsic antioxidant properties and health benefits make them ideal representatives of natural dyes as replacements for synthetic dyes. However, their instability can limit their use. A promising strategy to increase the color stability of anthocyanins is their interaction with clay minerals structures. Clay minerals have characteristics favorable to the stabilization of natural dyes, such as adsorption capacity, good surface chemistry, ion exchange capacity, abundance, non-toxicity, and environmental compatibility. This review summarizes relevant works that present different clays or clay minerals as robust inorganic matrices for incorporation, improved stability, and increased resistance against the thermal- and photodegradation of anthocyanins. In addition, several authors propose different applications for the formed anthocyanin-based hybrids.

“…The Fourier transform infrared (FTIR) spectra, transmitting electron microscopy (TEM), powder X-ray diffraction (XRD) analysis, Zeta potentials, Field emission transmission electron microscopy (TEM), and X-ray photoelectron spectroscopy (XPS) of the samples were obtained according to our previously reported methods ( Li et al, 2020a ). The elemental analysis of all samples was determined by Elementar analyzers varioEL cube (Elementar Analysen systeme GmbH, Germany).…”

“…As early as 1966, van Olphen confirmed, as Dogenech-Carbo et al later demonstrated, that Pal was more beneficial than other clay minerals in stabilizing the natural indigo molecules ( Van Olphen, 1966 ; Domenech-Carbo et al, 2013 ). To date, in order to stabilize natural pigments, such as betanin, flavylium cations and anthocyanin, and expand their application fields, Pal-based hybrid pigments have been developed due to the excellent performances, such as superior stability, fluorescence and acid/base reversible allochroic behavior ( Silva et al, 2018 ; Li et al, 2019a ; Li et al, 2020a ). In this context, Pal is an attractive supporting matrix that can be employed as an inorganic carrier to stabilize Cur molecules.…”

Curcumin is one of the dietary dyes extracted from turmeric and used for prevention and treatment of various illnesses. However, the low bioavailability and poor stability of curcumin limits its relevant applications. Therefore, different metal ions including Cu2+, Zn2+, Mg2+, Al3+, or Fe3+ were incorporated to tune the color, enhance the environmental stability and antioxidant activity of curcumin in the presence of palygorskite in this study. The as-prepared samples were studied using X-ray diffraction, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, Zeta potential, and transmission electron microscopy. In addition, the density functional theory calculation was also performed to explore the possible interaction among metal ions, curcumin and palygorskite. It was found that the color changing and stability enhancing were ascribed to the curcumin-metal ions coordination as well as chemical interactions between curcumin-metal complex and palygorskite. Moreover, the as-prepared composites showed more excellent color, thermal stability, antioxidant activity, and fluorescence properties than that of the curcumin/palygorskite composites due to the presence of metal ions. The finding of this investigation may contribute to developing the multifunctional composites with different colors and good antioxidant activity for relevant applications based on curcumin and palygorskite.

“…Glotov and Lvov, for example, reported a self-assembly strategy via centhyltrimethyl ammonium bromide onto negative HNTs surface, to obtain MCM-41/HNTs material with enhanced thermal and mechanical stability [ 12 ]. An example of chemical mixture between two clay was reported by Mu and Wang [ 13 ]. In this case palygorskite and halloysite were combined to improve betain adsortpion.…”

Synthesis and Characterization of Nanomaterial Based on Halloysite and Hectorite Clay Minerals Covalently Bridged

et al. 2021

Halloysite is an aluminosilicate clay with a predominantly hollow tubular structure (HNTs) able to act as a nanocontainer for the encapsulation of several chemicals. However, HNTs possess low affinity for metal ions in their pristine form and they need to be modified for improving their adsorption capabilities. Therefore, to overcome this issue herein we report a straightforward approach for the covalent modification of the external surface of halloysite nanotubes with hectorite clay. Compared to halloysite, hectorite possesses a lamellar structure with higher cation exchange capacity. The covalent linkage between the two clays was verified by several techniques (FTIR spectroscopy, 13C CP-MAS NMR, TGA, ζ-potential, DLS, and XRD measurements) and the morphology was imaged by TEM investigations. As proof of concept the adsorption ability of the obtained nanomaterial in comparison to pristine clays was proved using ciprofloxacin and silver ions chosen as models for their different chemical characteristics.
