However, its brittleness limits its standalone application. To overcome this, we incorporated 2-hydroxypropyl-beta-cyclodextrin (HP-β-CD) as a functional additive in zein biocoatings, leveraging its interaction with hydrophobic amino acids. We investigated how HP-β-CD affects zein aggregation at different temperatures, ethanol and zein concentrations. Results indicated that zein aggregation decreases with the introduction of HP-β-CD, leading to higher zein solubility. Optimized zein dispersions were utilized to prepare zein films, adding PEG 400 as a plasticizer. The impact of HP-β-CD on the physicochemical and structural properties of zein films was evaluated through orthogonal techniques. HP-β-CD improved the surface and barrier properties, reducing light transmission and water permeability by creating a denser matrix with improved structural integrity. Additionally, zein/HP-β-CD dispersions were directly applied to strawberries via dipping, forming coatings that extended shelf life, highlighting their potential as sustainable alternative to plastic food packaging. As many edible coatings require complex processing and functionalization with active ingredients, which are unnecessary in this case, this strategy offer exciting opportunities for improved food preservation across a broader range of applications, suggesting the need for further investigation.</div></div>","PeriodicalId":261,"journal":{"name":"Carbohydrate Polymers","volume":"367 ","pages":"Article 123969"},"PeriodicalIF":10.7,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144571803","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hydration-kinetics measurements further distinguish these components, underscoring the hydrophilicity of β-1,3-glucan versus the hydrophobicity of chitin.

The synergistic effects of incorporating nanomaterials into biopolymer matrices are discussed, highlighting their role in augmenting mechanical and different barrier characteristics. The review encompasses different barrier property requirements for flexible food packaging materials, biopolymer utilization in paper coatings using various approaches, and the potential of different nanomaterials and their composites. It also discusses multi-phase and multi-layer coating strategies for imparting multifunctional properties to paper-based packaging.
