“…Comparing the JPE containing films with the control film, it was possible to observe a band shift of 3300 for higher wavenumbers as JPE is added. According to Zhou et al [66], this In relation to the extract, it is possible to observe a peak at 1630 that can be related to the aromatic ring, which is confirmed by literature [65]. According to what was expected, this signal was less intense in the films containing JPE than the freeze-dried extract.…”

“…Comparing the JPE containing films with the control film, it was possible to observe a band shift of 3300 for higher wavenumbers as JPE is added. According to Zhou et al [66], this fact is related to the interaction between anthocyanins, present in the extract, and carrageenan matrix. Another change between the control film and extract embedded films is observed in the range around 1262 cm −1 .…”

This research focused on the development of active and intelligent films based on a carrageenan biopolymer incorporated with jaboticaba peels extract (JPE). The bioactive extract was obtained by maceration extraction and showed high concentrations of total phenolic content (TP), total anthocyanin (TA), cyanidin-3-glucoside (Cn-3-Glu), antioxidant activity (AA), and microbial inhibition (MI) against E. coli, being promising for use as a natural additive in food packaging. The carrageenan films were produced using the casting technique, incorporating different concentrations of JPE, and characterized. The results of the thickness and Young’s modulus of the film increased in the films supplemented with JPE and the addition of the extract showed a decrease in elongation capacity and tensile strength, in water vapor permeability, and a lower rate of swelling in the water. In addition, the incorporation of JPE into the polymeric matrix promotes a change in the color of the films when compared to the control film and improves the opacity property. This is a positive effect as the material has a UV-vis light barrier which is interesting for food packaging. The increase in the active potential of the films was directly proportional to the concentration of JPE. The films results showed visible changes from purple to brown when in contact with different pH, which means that films have an intelligent potential. Accordingly, this novel carrageenan based-film incorporated with JPE could be a great strategy to add natural additives into packaging material to obtain an active potential and also an indicator for monitoring food in intelligent packaging.

“…Recently, there has been an increasing interest in developing optical sensors or indicators with high sensitivity and selectivity by using curcumin as a necessary reagent for colorimetric detection while other natural biopolymer-based materials as carriers [24,25]. The encapsulation could be a new strategy by fabricating curcumin particles within a matrix or shell material to form a capsule thus, overcome the limitations of curcumin and thereby increasing the bioavailability, solubility, and stability of curcumin.…”

Development of Aloe Vera-Green Banana Saba-Curcumin Composite Film for Colorimetric Detection of Ferrum (II)

et al. 2022

This study was performed to develop and characterize a bio-film composed of Aloe vera (Aloe barbadensis), green banana Saba (Musa acuminata x balbisiana), and curcumin for the detection of Fe2+ ions. Cross-linking interaction between banana starch-aloe vera gel and banana starch-curcumin enhanced l the sensing performance of the composite film towards divalent metal ions of Fe2+. The morphological structure of the Aloe vera-banana starch-curcumin composite revealed a smooth and compact surface without cracks and some heterogeneity when observed under Scanning Electron Microscopy (SEM). The thickness, density, color property, opacity, biodegradation, moisture content, water-solubility, water absorption, swelling degree, and water vapor permeability of bio-films were measured. The incorporation of aloe vera gel and curcumin particles onto the banana starch film has successfully improved the film properties. The formation of the curcumin-ferrum (II) complex has triggered the film to transform color from yellow to greenish-brown after interaction with Fe2+ ions that exhibit an accuracy of 101.11% within a swift reaction time. Good linearity (R2 = 0.9845) of response on colorimetric analysis was also obtained in Fe2+ ions concentration that ranges from 0 to 100 ppm, with a limit of detection and quantification found at 27.84 ppm and 92.81 ppm, respectively. In this context, the film was highly selective towards Fe2+ ions because no changes of color occur through naked eye observation when films interact with other metal ions, including Fe3+, Pb2+, Ni2+, Cd2+, and Cu2+. Thus, these findings encourage curcumin-based starch films as sensing materials to detect Fe2+ ions in the field of food and agriculture.

“…Biopolymer-based films feature many disadvantages that must be overcome, including: poor mechanical strength, high solubility, and high gas permeability. Biopolymer, doubleor multilayer films can overcome these disadvantages, as each of the layers adheres to the others and can be enriched by different active substances [10,11]. Zhang, et al [12] added the antibacterial ingredient cinnamon essential oil to the multilayer films based on chitosan and sodium alginate.…”

“…Double-layered films based on furcellaran, CMC, and gelatin hydrolysate enriched with lingonberry extract demonstrated very high thermal stability as well as antioxidant and antimicrobial activity [13]. Zhou et al [11] produced a double-layered indicator film, where the indicator layer was made of carrageenan, curcumin and/or anthocyanin, and the emulsified layer made of konjac glucomannan and camellia oil. The resulting double-layered indicator film demonstrated a distinct colour change when monitoring the freshness of the chicken meat.…”

Active Double-Layered Films Enriched with AgNPs in Great Water Dock Root and Pu-Erh Extracts

et al. 2021

A novel, eco-friendly, and biocompatible method was applied to form silver nanoparticles (AgNPs) in great water dock (Lapathi radix) (KB) and pu-erh (Camellia sinensis) (PE) extracts. The surface plasma resonance peak of green synthesized AgNPs at 451.8 nm for AgNPs+KB and 440.8 nm for AgNPs+PE was observed via spectral analysis of UV absorbance. In this study, double-layered biopolymer films (FUR/CHIT+HGEL) with AgNPs incorporated in KB solution (AgNPs+KB) and AgNPs in PE solution (AgNPs+PE), were successfully prepared using the casting method. The SEM, XRD, zeta potential and size analyses confirmed the presence of AgNP in the films. The addition of AgNPs in plant extracts improved antimicrobial and antioxidant activity and thermal stability, whereas WVTR experienced a decrease. The nanocomposite films’ orange-brown colour may aid in the protection of food products against UV rays. The composite films demonstrated antibacterial activity against food-borne pathogens and may offer potential in food packaging applications.
