“…GSE enters the cell by rupturing the membrane and may attach to cellular proteins to disable their function [37,39]. Previously, in several reports, the vigorous antibacterial activity of GSE has been reported [37,44,[57][58][59]. A CNF-based nanocomposite film with intense antibacterial action can help a packaging film to expand a food's shelf life by preventing microbial contamination.…”

Cellulose Nanofiber-Based Nanocomposite Films Reinforced with Zinc Oxide Nanorods and Grapefruit Seed Extract

Here, we report the fabrication and characterization of cellulose nanofiber (CNF)-based nanocomposite films reinforced with zinc oxide nanorods (ZnOs) and grapefruit seed extract (GSE). The CNF is isolated via a combination of chemical and physical methods, and the ZnO is prepared using a simple precipitation method. The ZnO and GSE are used as functional nanofillers to produce a CNF/ZnO/GSE film. Physical (morphology, chemical interactions, optical, mechanical, thermal stability, etc.) and functional (antimicrobial and antioxidant activities) film properties are tested. The incorporation of ZnO and GSE does not impact the crystalline structure, mechanical properties, or thermal stability of the CNF film. Nanocomposite films are highly transparent with improved ultraviolet blocking and vapor barrier properties. Moreover, the films exhibit effective antimicrobial and antioxidant actions. CNF/ZnO/GSE nanocomposite films with better quality and superior functional properties have many possibilities for active food packaging use.

“…The development and utilization of grape seed in industry can not only optimize the environment and save resources, but also create good social economic and social bene ts. Studies have shown that GSE can scavenge excess free radicals in vivo, is an effective broad-spectrum antimicrobial agent, and has a high-e ciency antioxidant effect (Choi et al, 2014). Polyphenols in grape seeds are usually extracted using ethanol, its main functions are antioxidant, skin protection, blood pressure reduction, and heart rate reduction (Foshati et al, 2021).…”

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 been reported that flavonoids have an inhibitory effect on gram-positive and gram-negative bacteria and some Candida species by various mechanisms [13–17]. Indeed, GSE is reported to have powerful antibacterial and antifungal properties [12, 18, 19], and it has been studied extensively as a natural preservative of food [20–23]. These studies suggest that GSE has the potential to cleanse C .…”

Grapefruit seed extract effectively inhibits the Candida albicans biofilms development on polymethyl methacrylate denture-base resin

et al. 2019

This study aimed to investigate the cleansing effects of grapefruit seed extract (GSE) on biofilms of Candida albicans ( C . albicans ) formed on denture-base resin and the influence of GSE on the mechanical and surface characteristics of the resin. GSE solution diluted with distilled water to 0.1% (0.1% GSE) and 1% (1% GSE) and solutions with Polident® denture cleansing tablet dissolved in distilled water (Polident) or in 0.1% GSE solution (0.1% G+P) were prepared as cleansing solutions. Discs of acrylic resin were prepared, and the biofilm of C . albicans was formed on the discs. The discs with the biofilm were treated with each solution for 5 min at 25°C. After the treatment, the biofilm on the discs was analyzed using a colony forming unit (CFU) assay, fluorescence microscopy, and scanning electron microscopy (SEM). In order to assess the persistent cleansing effect, the discs treated with each solution for 5 min were aerobically incubated in Yeast Nitrogen Base medium for another 24 h. After incubation, the persistent effect was assessed by CFU assay. Some specimens of acrylic resin were immersed in each solution for 7 days, and changes in surface roughness (Ra), Vickers hardness (VH), flexural strength (FS), and flexural modulus (FM) were evaluated. As a result, the treatment with 1% GSE for 5 min almost completely eliminated the biofilm formed on the resin; whereas, the treatment with 0.1% GSE, Polident, and 0.1% G+P for 5 min showed a statistically significant inhibitory effect on biofilms. In addition, 0.1% GSE and 0.1% G+P exerted a persistent inhibitory effect on biofilms. Fluorescence microscopy indicated that Polident mainly induced the death of yeast, while the cleansing solutions containing at least 0.1% GSE induced the death of hyphae as well as yeast. SEM also revealed that Polident caused wrinkles, shrinkage, and some deep craters predominantly on the cell surfaces of yeast, while the solutions containing at least 0.1% GSE induced wrinkles, shrinkage, and some damage on cell surfaces of not only yeasts but also hyphae. No significant changes in Ra, VH, FS, or FM were observed after immersion in any of the solutions. Taken together, GSE solution is capable of cleansing C . albicans biofilms on denture-base resin and has a persistent inhibitory effect on biofilm development, without any deteriorations of resin surface.
