Sustainable Fruit Preservation Using Algae-Based Bioactive Coatings on Textile Packaging

Resources, Journal Year: 2025, Volume and Issue: 14(1), P. 15 - 15

Published: Jan. 16, 2025

This study explores the potential of using natural textile packaging infused with algae-based coatings as an eco-friendly alternative to traditional plastic for extending fruit shelf life. Traditional is known release harmful chemicals into both food and environment, which underscores need safer, more sustainable alternatives. investigates algae from three distinct groups—green, red, brown algae—renowned their rich bioactive compounds that exhibit preservative properties. Algae powders were prepared via immersion in purified water, boiling, mixing gum arabic form a gelatinous coating solution. The was applied knitted fabric, then crafted bags storing fruits such tomatoes apples. Over 21 days, texture, weight loss, juice content stored algae-coated monitored compared those uncoated packaging. results showed demonstrated significantly less loss retained better texture. In terms weight, combination green, lowest reduction (4.2%) apples (3.8%) after outperforming packaging, exhibited reductions 11.2% 10.8%, respectively. These findings support reduce reliance on conventional plastics while maintaining quality during storage.

Effect of Ultrasound and Freeze‐Drying to Enhance the Extraction of Phenolic Compounds in Dragon Fruit Peels and Apply Them in Edible Starch‐Based Films

Packaging Technology and Science, Journal Year: 2024, Volume and Issue: 37(9), P. 901 - 916

Published: July 2, 2024

ABSTRACT In this study, dragon fruit peels were subjected to different times (5, 10, 15, 20 and 25 min) of ultrasound pretreatment (4.870 W m −2 /25°C) then freeze‐drying (FD) (−56°C/48 h) obtain powder particles, which underwent physical–chemical, functional structural characterisation. Additionally, the extraction total phenolic compound (TPC) was evaluated through ultrasound‐assisted kinetics mechanical agitation. Finally, films based on black rice starch developed with addition (0.5, 1.5 2.5%) peel their physical, barrier, antioxidant, properties evaluated. The results obtained showed that all particles had low water content (4.21%–6.58%) high solubility (84.62%–88.73%) a reduction in particle size (23.21–39.32 μm). TPC, synergistic effect tested conditions increased efficiency, reaching 686.66 mg GAE/100 g for pretreated (25 180 min extraction. Furthermore, type ‘A’ crystallinity structure did not change significantly pretreatment, but there peak area, reflecting relative crystallinity, maximum decrease 29.04%. starch‐based produced 2.5% (28.72%) vapour permeability (5.03 × 10 −8 mm s −1 2 Pa), however, they contained higher levels TPC (31.78 film) antioxidant activity (8.17 μmol TE/g easily migrated aqueous medium. also presented values tensile strength at break (3.41 MPa) Young's modulus (4.18 MPa), as well value elongation (45.82%). our highlight potential FD peels, paving way development food packaging.

Recent Advances in Purple Sweet Potato Anthocyanins: Extraction, Isolation, Functional Properties and Applications in Biopolymer-Based Smart Packaging

Foods, Journal Year: 2024, Volume and Issue: 13(21), P. 3485 - 3485

Published: Oct. 30, 2024

Petroleum-based plastic packaging materials have negative impacts on the environment and food safety. Natural biopolymer-based are proper substitutes for plastic-based ones, which is because biopolymers nontoxic, biodegradable even edible. The incorporation of bioactive functional substances into a film matrix can produce novel smart materials. Anthocyanins, one class natural colorants with potent antioxidant activity pH-response color-changing ability, suitable producing films. purple sweet potato rich in anthocyanins. In past decade, numerous studies reported extraction anthocyanins from utilization (PSPAs) production. However, no specific review has summarized recent advances films containing PSPAs. Therefore, this review, we aim to systematically summarize progress extraction, isolation, characterization, purification properties Moreover, thoroughly introduce preparation methods, physical properties, antimicrobial activity, pH sensitivity, stability applications Factors affecting PSPAs as well discussed.
