Biodegradable active packaging films with antimicrobial and antioxidant functions have received much attention due to the food safety and plastic pollution issues. This study prepared and characterized a novel bioactive binary composite film based on gelatin (Ge) and dextran (Dx) incorporated with various concentrations (0%, 0.3%, 0.6%, 0.9%, 1.2%, w/w) of citronellal (Cit) and α‐tocopherol (Toc). The thickness, L*, b*, total color difference, water contact angle, opacity, and crystallinity of film significantly increased, whereas the film solubility, swelling degree, water vapor permeability, tensile strength, elongation at break, and a* of film significantly decreased with the increase of Cit and Toc concentrations. However, the addition of Cit and Toc had no significant effect on the film's moisture content and thermal stability. Fourier transforms infrared spectral pattern indicated that physical interactions (H‐bonding) between biopolymer matrix and active fillers were formed. Scanning electron microscope images showed that the film added with active fillers had a rough surface and a spongelike cross‐section structure compared to control film. Moreover, the release curves of Cit and Toc showed that the film in 95% ethanol solution had the longest release time. Furthermore, the film added with Cit and Toc effectively inhibited the growth of pathogenic and spoilage bacteria (Shewanella putrefaciens and Escherichia coli) and quenched the free radicals (2,2‐diphenyl‐1‐picrylhydrazyl and 2,2′‐azino‐bis(3‐ethylbenzthiazoline‐6‐sulfonic acid)). Overall, it can be inferred that the Ge–Dx‐based composite film incorporated with Cit and Toc is a potential antibacterial and antioxidant biodegradable material for food packaging applications to maintain food quality.

“…It was possible to notice angular deformation of CH 2 at 1450 cm −1 and in the region 1390 cm −1 vibrations of the angular deformation type of CH 3 . In the band at 1330 cm −1 angular vibrations are observed in the plane of the OH bond, in 1240 cm −1 and 1080 cm −1 absorption of unconjugated C–N bond, in primary and secondary amines [ 11 ].…”

Development of Gelatin/Misoprostol Compounds for Use in Pregnancy Failures

Early abortion is one of the most common complications during pregnancy. However, the frequent handling of the genital region, more precisely the vagina, which causes discomfort to patients in this abortion process due to the frequency of drug insertion, as four pills are inserted every six hours, has led to the search for alternatives to alleviate the suffering caused by this practice in patients who are already in a shaken emotional state. Hence, this work aimed to develop composites of gelatin and misoprostol, using a conventional single-dose drug delivery system. These composites were prepared by freeze/lyophilization technique, by dissolving the gelatin in distilled water, with a concentration of 2.5% (w/v), and misoprostol was incorporated into the gelatin solution at the therapeutic concentration (800 mcg). They were subsequently molded, frozen and lyophilized. The samples of the composites were then crosslinked with sodium tripolyphosphate (TPP) 1% (v/v) with respect to the gelatin mass for 5 min. The characterization techniques used were: Optical Microscopy (OM), Fourier Transformed Infrared Spectroscopy (FTIR), Thermogravimetry (TG), Swelling, Biodegradation and Cytotoxicity. In OM it was observed that the addition of the drug improved the cylindrical appearance of the compounds, in comparison with the sample that was composed of only gelatin. There was a reduction in the degree of swelling with the addition of the drug and crosslinking. The cytotoxicity test indicated the biocompatibility of the material. Based on the results obtained in these tests, the composites have therapeutic potential for uterine emptying in pregnancy failures, especially in the first trimester.

“…The radical scavenging activities of the films increased with the EO concentration reaching ABTS and DPPH values of 43.08% and 51.98%, respectively, at 1.5% java citronella EO. Similarly, Tügen et al [ 77 ] developed gelatin/chitosan films enriched with different concentrations of lemon essential oil (0.25, 0.50, 0.75, and 1%) and observed that the films containing EO displayed antioxidant activity with DPPH values ranging from 13.12 to 60.20%, ABTS 21.43–73.70%, and metal chelating activity from 52.04% to 79.99% while the control films showed no antioxidant capacity.…”

Chitosan is the deacetylated form of chitin regarded as one of the most abundant polymers and due to its properties, both chitosan alone or in combination with bioactive substances for the production of biodegradable films and coatings is gaining attention in terms of applications in the food industry. To enhance the antimicrobial and antioxidant properties of chitosan, a vast variety of plant extracts have been incorporated to meet consumer demands for more environmentally friendly and synthetic preservative-free foods. This review provides knowledge about the antioxidant and antibacterial properties of chitosan films and coatings enriched with natural extracts as well as their applications in various food products and the effects they had on them. In a nutshell, it has been demonstrated that chitosan can act as a coating or packaging material with excellent antimicrobial and antioxidant properties in addition to its biodegradability, biocompatibility, and non-toxicity. However, further research should be carried out to widen the applications of bioactive chitosan coatings to more foods and industries as well was their industrial scale-up, thus helping to minimize the use of plastic materials.
