“…The DTG curves illustrate that the ACNPs are more thermally stable than CNPs, which means that the incorporation of anthocyanin enhanced the stability of the chitosan biopolymer matrix due to the formation of electrostatic attractions between the chitosan matrix and the anthocyanin 34 . The CNPs exhibited peak maxima at 61.9 and 287.1 °C, whereas for ACNPs these were at 59.7 and 282.4 °C.…”

BACKGROUND Anthocyanins are flavonoids that are potential antioxidant, anti‐inflammatory, anti‐obesity, and anti‐carcinogenic nutraceutical ingredients. However, low chemical stability and low bioavailability limit the use of anthocyanins in food. Nanoencapsulation using biopolymers is a recent successful strategy for stabilization of anthocyanins. This study reports the development, characterization, and antioxidant activity of black carrot anthocyanin‐loaded chitosan nanoparticles (ACNPs). RESULTS The ionic gelation technique yielded the ACNPs. The mean hydrodynamic diameter d and polydispersity index PDI of chitosan nanoparticles and ACNPs were found to be d = 455 nm and PDI = 0.542 respectively for chitosan nanoparticles and d = 274 nm and PDI = 0.376 respectively for ACNPs. The size distribution was bimodal. The surface topography revealed that the ACNPs are spherical and display a coacervate structure. Fourier transform infrared analysis revealed physicochemical interactions of anthocyanins with chitosan. The loading process could achieve an encapsulation efficiency of 70%. The flow behavior index η of encapsulated ACNPs samples revealed Newtonian and shear thickening characteristics. There was a marginal reduction in the in vitro antioxidant potential of anthocyanins after nanoencapsulation, as evidenced from 2,2‐diphenyl‐1‐picrylhydrazyl, ferric reducing antioxidant power, and 2,2′‐azino‐bis(3‐ethylbenzothiazoline‐6‐sulfonic acid) assays. Interestingly, the in vivo antioxidant potential of anthocyanins improved following nanoencapsulation, as observed in the serum antioxidant assays. CONCLUSION The optimized nanoencapsulation process resulted in spherical nanoparticles with appreciable encapsulation efficiency. The nanoencapsulation process improved the in vivo antioxidant activity of anthocyanins, indicating enhanced stability and bioavailability. The promising antioxidant activity of the ACNPs suggests a potential for utilization as a nutraceutical supplement. © 2021 Society of Chemical Industry.

“…Typically, the films formed by chitin are mechanically weaker and have worse barrier properties than those formed by chitosan. As with other biopolymers, the functional performance of chitin and chitosan films can be improved by combining them with proteins or other polysaccharides, or by incorporating other functional additives [ 28 , 42 ]. The fact that both chitin and chitosan naturally exhibit antimicrobial activity is useful for the development of active biodegradable films that can increase the shelf life of foods [ 42 , 51 ].…”

“…pH-sensitive indicators have been developed using anthocyanins derived from various botanical sources, including saffron petal [ 42 ], black rice bran [ 184 ], hibiscus [ 185 ], purple corn [ 186 ], black soybean seed coat [ 44 ], purple onion peel [ 187 ], roselle [ 163 , 188 ], red barberry [ 28 , 79 ], blueberry [ 20 , 43 ], purple sweet potato [ 189 , 190 ], red cabbage [ 132 , 191 ], as well as from carotenoids [ 192 , 193 ], betalains [ 194 , 195 ] and chlorophylls [ 196 ]. The response of these natural pigments to pH changes depends on their molecular structure, as well as on environmental conditions, such as temperature, oxygen levels, and light exposure [ 197 ].…”

Interest in the development of smart and active biodegradable packaging materials is increasing as food manufacturers try to improve the sustainability and environmental impact of their products, while still maintaining their quality and safety. Active packaging materials contain components that enhance their functionality, such as antimicrobials, antioxidants, light blockers, or oxygen barriers. Smart packaging materials contain sensing components that provide an indication of changes in food attributes, such as alterations in their quality, maturity, or safety. For instance, a smart sensor may give a measurable color change in response to a deterioration in food quality. This article reviews recent advances in the development of active and smart biodegradable packaging materials in the food industry. Moreover, studies on the application of these packaging materials to monitor the freshness and safety of food products are reviewed, including dairy, meat, fish, fruit and vegetable products. Finally, the potential challenges associated with the application of these eco-friendly packaging materials in the food industry are discussed, as well as potential future directions.

“…In the nanomaterial synthesis process, polysaccharides can be reacted under drastic conditions, such as high temperatures, salt contents, and shear forces, with relatively stable structures and biological activities compared with nucleic acids and proteins ( Yuan et al, 2018 ; Garcia-Vaquero et al, 2019 ; Wang et al, 2019a ; Chao et al, 2020 ; Chen B. et al, 2020 ). Therefore, by using polysaccharides and their derivatives, nanomaterials with different types of geometric structures can be prepared, from zero- to three-dimensional, through various synthetic methods, such as hydrothermal synthesis and co-precipitation ( Ferreira et al, 2020 ; Alizadeh-Sani et al, 2021 ; Pan et al, 2021 ). Nanoparticles, nanocapsules, and nanomicelles are typical zero-dimensional drug carriers; nanoparticles are characterized by a uniform distribution of the drug and carrier, while the drug in the latter two is encapsulated in the carrier core.…”

Ocular drug delivery is one of the most challenging issues in ophthalmology because of the complex physiological structure of the eye. Polysaccharide-based nanomaterials have been extensively investigated in recent years as ideal carriers for enhancing the bioavailability of drugs in the ocular system because of their biocompatibility and drug solubilization. From this perspective, we discuss the structural instability of polysaccharides and its impact on the synthesis process; examine the potential for developing bioactive polysaccharide-based ocular drug nanocarriers; propose four strategies for designing novel drug delivery nanomaterials; and suggest reviewing the behavior of nanomaterials in ocular tissues.
