“…The barberry pigment was reddish/crimson under acidic conditions and yellowish under alkaline conditions, while the saffron pigment was reddish/pink under acidic conditions and greenish/yellow under alkaline conditions. Similar pH-induced color changes have been reported for anthocyanins derived from other plant sources (alizarin and grapefruit seed) that were incorporated into carboxymethyl cellulose/agar films [ 13 ]. These results highlight the pH sensitivity of the anthocyanin-loaded biopolymer films, which may be useful for monitoring changes in the quality or freshness of some foods.…”

“…Natural plant-derived substances that change color in response to changes in food properties have been widely used in the development of smart biodegradable packaging materials, e.g., anthocyanins, curcumin, quercetin, betalain, and alizarin [ 6 , 10 , 12 , 13 ]. Saffron and barberry anthocyanins are commonly utilized for this purpose because of their pH sensitivity, antioxidant property, ecofriendly, non-toxicity, and affordability.…”

Smart Biopolymer-Based Nanocomposite Materials Containing pH-Sensing Colorimetric Indicators for Food Freshness Monitoring

Nanocomposite biopolymer materials containing colorimetric pH-responsive indicators were prepared from gelatin and chitosan nanofibers. Plant-based extracts from barberry and saffron, which both contained anthocyanins, were used as pH indicators. Incorporation of the anthocyanins into the biopolymer films increased their mechanical, water-barrier, and light-screening properties. Infrared spectroscopy and scanning electron microscopy analysis indicated that a uniform biopolymer matrix was formed, with the anthocyanins distributed evenly throughout them. The anthocyanins in the composite films changed color in response to alterations in pH or ammonia gas levels, which was used to monitor changes in the freshness of packaged fish during storage. The anthocyanins also exhibited antioxidant and antimicrobial activity, which meant that they could also be used to slow down the degradation of the fish. Thus, natural anthocyanins could be used as both freshness indicators and preservatives in biopolymer-based nanocomposite packaging materials. These novel materials may therefore be useful alternatives to synthetic plastics for some food packaging applications, thereby improving the environmental friendliness and sustainability of the food supply.

“…This may be due to the high carbon content, resulting in a high heat tolerance (Niazi et al, 2015, Kiwalczyk et al, 2021. Similar results were found by Roy et al (2021b), who found that when GSE and alizarin is added to the chitosan lm could effectively increase the thermal stability of the lm. Similar results were obtained by Niazi et al (2015).…”

A biodegradable packaging film with antioxidant and antibacterial activity was developed by adding grape seed ethanol extract (1%、3%、5% per g of starch) to corn starch/κ-carrageenan (CS/кC) complex film made using the solvent casting method. The κ-carrageenan is a promising film-forming polymer with highly elastic and adhesive properties. The addition of GSE enhanced the water vapor permeability, break elongation, and opacity of the film, and this is related to the excellent dispersion of GSE in CS/кC film observed by scanning electron microscope, and the formation of intermolecular hydrogen bond between GSE and CS proved by FT-IR. Thermogravimetric analysis showed that the CS/кC -5% GSE film has a high glass transition temperature (121.65℃). With the increase of GSE content, it improved the antioxidant capacity (DPPH radical scavenging 26.5% and ABTS radical scavenging 45.0%) and antibacterial activity (Bacteriostatic circle diameter of E. coli 12.78 ± 0.42 mm and S. aureus strains 13.52 ± 0.66 mm) of CS/кC films. Simulated food packaging experiments presented that CS/кC-GSE film significantly reduced the peroxide value of lard (P < 0.05). The above results indicate that the GSE can be used as a food-grade packaging material and has a good application prospect in the food industry.

“…It has recently been shown that polysaccharide-protein mixtures are useful for making biodegradable active packaging films [ 10 , 11 , 12 , 13 , 14 , 15 ]. For this purpose, chitosan and gelatin are ideal choices for producing binary blends of biopolymer films.…”

Functional food packaging films were prepared using a binary mixture of chitosan and gelatin through crosslinking with genipin and hybridization with rosemary essential oil and quercetin. The mixture of chitosan and gelatin produced the compatible film, and the added fillers also showed good compatibility. The physical properties of the chitosan/gelatin film were not greatly affected by crosslinking with genipin, and the functionality of the composite film was increased by the addition of rosemary essential oil and quercetin. The bioactive additives did not significantly affect the hydrophobicity and water vapor barrier properties of the chitosan/gelatin film but significantly changed the color, while the mechanical and thermal properties were slightly affected. The addition of these functional fillers significantly improved the UV protection, antioxidant, and antibacterial properties of the chitosan/gelatin film. Therefore, the novel chitosan/gelatin film with genipin crosslinking and the integration of rosemary essential oil and quercetin is considered to have high potential for applications in active food packaging.
