Chitosan films incorporated with antioxidant extract of acerola agroindustrial residue applied in chicken thigh

Abstract

Biodegradable materials have great potential to improve and maintain the food quality. Chitosan biofilms (1% wt/vol) added with three concentrations of extract of acerola agroindustrial residue (vol/wt) were produced: 0% (G1); 1.0% (G2); and 2.5% (G3). The study was conducted in two main stages: in the first step, samples of all three groups and a control group (GC) were stored for 18 days (4 °C ± 1 °C), being analyzed for TBARS and pH. The groups 1 and G2 showed the best results. In the second stage, chicken meat packed with biofilms G1, G2, and a new GC were stored for 20 days (4 °C ± 1 °C), being evaluated for pH, temperature, TBARS, color parameters, water‐holding capacity, TPA, and microbiological analysis. The biofilm G2 presented the best results, maintaining the quality of the samples for 20 days of storage. Practical applications The film developed in this work has as main characteristics the biodegradability and the antioxidant activity, which were incorporated into the film with an antioxidant extract of acerola, produced from the agroindustrial residue of acerola, a byproduct usually discarded by the juice industry. For the development of this film, low‐cost materials and straightforward equipment were used, their application in the chicken meat was simple and the results were satisfactory, since the lipid oxidation was delayed and the quality of the product was maintained for 20 days. It can be observed that the chitosan film produced in this work is a package with significant active functions and an ally in maintaining the quality of the chicken meat. It is believed that this film will also be efficient in delaying the lipid oxidation of other meat products. Further investigation are necessary to confirm this.

Biodegradable Antimicrobial Food Packaging: Trends and Perspectives

“…The antimicrobial activity was tested on bread slices, on which the chitosan-essential oil package managed to block the fungus growth [206]. The possible use of agricultural waste was further exemplified by Zegarra, M. et al who have used chitosan films loaded with acerola extract from residues to extend the shelf life of meat [164].…”

Potential agrifood application of seriguela (Spondias purpurea L.) residues extract and nanoZnO as antimicrobial, antipathogenic and antivirulence agents

“…The method proposed by Andrade et al (2015) andPortugal Zegarra et al (2018), with modifications, was used for the extraction of the phenolic compounds of the seriguela residue flour, in which 10g of the flour (item 2.1) were mixed with 50mL of 60% ethanol solution under constant stirring (400 rpm) for 30 minutes on a digital mechanical stirrer (TE -039/1 -Tecnal) at 23 ± 2°C. Then, the mixture was centrifuged (centrifuge CT-6000 R-CIENTEC) at 4000 rpm for 15 minutes and the precipitate was resuspended in 50 mL of 60% ethanol solution and centrifuged again.…”

“…Furthermore, ZnO nanoparticles also showed potential use as an antimicrobial agent (Duffy et al, 2018;Kanmani & Rhim, 2014). Concerning these approaches, the research group at UFPE/UFRPE (Brazil) has explored the active properties of components from agroindustrial waste such as acerola described by (Portugal Zegarra et al, 2018), and nanoZnO (Arroyo et al, 2020;Andrelina Maria Pinheiro Santos et al, 2019) in edible food coatings and films improving food preservation. Moreover, other researchers have studied applications of nanoZnO and plant extracts in active or drug delivery systems and wound treatments for medical field (Nafchi et al, 2013;Rahman et al, 2020) By analyzing the results obtained in the antibacterial action assays, it was possible to notice that the pure extract (without dilution) showed antimicrobial action against the strain of Clavibacter michiganensis pv michiganensis.…”

Chitosan–Ellagic Acid Nanohybrid for Mitigating Rotenone-induced Oxidative Stress

“…Considering the known antioxidant properties and highly sustainable nature, chitosan (CS) and ellagic acid were selected as the primary components for the enclosure and drug, respectively . CS is a biodegradable linear polysaccharide derived from chitin shells of shrimp and other crustaceans with previously documented biocompatibility, antioxidant property, and permeability-enhancing properties. − EA, a polyphenol found in fruits and vegetables, possesses a wide spectrum of biological activities such as antioxidant, antiviral, anticancer, and antimutagenic properties, with potential toxicity at higher doses. ,− …”
