Smart Packaging for Food Spoilage Assessment Based on Hibiscus sabdariffa L. Anthocyanin-Loaded Chitosan Films

Journal of Composites Science, Journal Year: 2023, Volume and Issue: 7(10), P. 404 - 404

Published: Sept. 24, 2023

An on-package colorimetric label was fabricated using Hibiscus sabdariffa L. anthocyanin as a freshness indicator because its color depends on pH. The anthocyanins were embedded within chitosan matrix. labels applied to estimate the spoilage of fish food during storage at 25 °C for 3 days. According scanning electron microscopy results, inclusion in matrix resulted formation dense and uniform film. had acceptable thicknesses (78–85 µm), moisture contents (14–16%), swelling indices (84–102%), water vapor permeabilities (3.0–3.2 × 10−11 g m/m2 s Pa), tensile strengths (11.3–12.3 MPa), elongation breaks (14–39%). It is noteworthy that can distinguish by turn from light brown (fresh) grayish (spoiled) naked-eye, due alterations pH content volatile basic nitrogen storage. Our results indicate all-natural be an effective method monitor storage, which may improve quality sustainability.

Monitor the freshness of shrimp by smart halochromic films based on gelatin/pectin loaded with pistachio peel anthocyanin nanoemulsion

Food Chemistry X, Journal Year: 2024, Volume and Issue: 21, P. 101217 - 101217

Published: Feb. 20, 2024

This paper focuses on the combination of gelatin (Gel), pectin (Pec), and Pistachio peel anthocyanins (PSAs) to develop a halochromic film for food applications (shrimp). The results spectroscopic properties showed that components had proper interaction compatibility. Furthermore, addition PSAs Pec improved thermal stability films. significantly physical mechanical resistance So that, permeability water vapor oxygen reduced from 2.81 2.74 (g‧s−1‧Pa−1‧m−1) 5.25 4.70 (meq/kgO2), respectively. In addition, strength flexibility reached 0.7 MPa 56 % compared Gel (0.62 MPa, 46.96 %). Most importantly, color changes smart cherry/pink yellow/brown, which were proportional anthocyanin solution at different pHs, able monitor shrimp freshness spoilage room (20 °C) refrigerated (4 temperature 14 days.

Development of Intelligent Indicators Based on Cellulose and Prunus domestica Extracted Anthocyanins for Monitoring the Freshness of Packaged Chicken

International Journal of Biomaterials, Journal Year: 2024, Volume and Issue: 2024, P. 1 - 10

Published: March 28, 2024

Meat is a widely consumed food globally; however, variations in storage conditions along its supply chain can pose potential safety risk for consumers. Addressing this concern, we have developed freshness indicators designed to monitor the condition of packaged chicken. In study, anthocyanins were infused with cellulose paper measuring 2 × cm, and subsequent analysis focused on examining color changes concerning deteriorating chicken stored at 30°C 48 h, varying sample sizes being considered. The rise total volatile nitrogen (TVB-N) compounds from an initial value 3.64 ± 0.39 mg/100 g 28.17 1.46 acted as stimulus change indicator, simultaneously influencing pH 7.03 0.16 8.12 0.39. microbial load (aerobic plate count) samples was also significantly increased.

Abstract This study explores the utilization of lignocellulosic biomass derived from Syzygium cumini seeds ( S. Cumini ) as an eco‐friendly reinforcing filler for polyvinyl chloride (PVC) composites. The need sustainable and biodegradable materials in polymer applications motivated this work, particularly to address environmental concerns associated with conventional PVC. Composite films varying concentrations seed were prepared using solution casting technique. structural integrity interactions within composites confirmed through X‐ray diffraction (XRD) Fourier‐transform infrared (FTIR) spectroscopy. SEM analysis showed average particle size 6–14 μm also revealed modifications morphology upon addition. Biodegradability was assessed hydrolytic degradation soil‐burial tests, indicating enhanced compatibility compared pure hydrophilicity improved, indicated by increasing water contact angle 79.4° (hydrophilic) 107° (hydrophobic). Suppressed aureus activity PVC composite film has shown its antimicrobial behavior. These properties suggest that – reinforced can serve promising polymer‐based medical devices, offering resistance bacterial contamination while addressing sustainability challenges. Highlights Lignocellulosic used films. extract improved Hydrolytic dehydration tests biodegradability. Hydrophilicity increased, evidenced a rise angle. Better enhances use devices.
