The focus has gradually shifted to safety and sustainability in the preparation of functional food packaging materials. In this study, a bisquaternary ammonium salt of tannic acid (BQTA) was synthesized, and the bioplastics based on BQTA and polyvinyl alcohol (PVA) were created for packaging applications. The impact of BQTA on antibacterial effect, antioxidant capacity, opacity, ultraviolet (UV) protective activity, mechanical strength, thermal stability, and anti-fog of the resultant bioplastics was examined. In vitro antibacterial experiments confirmed that BQTA possesses excellent antimicrobial properties, and only a trace amount addition of BQTA in PVA composite film could inhibit about 100% of Escherichia coli and Staphylococcus aureus. Compared to BQTA\/PVA bioplastics with pure PVA, the experiment findings demonstrate that BQTA\/PVA bioplastics show strong antioxidant and UV protection action and the performance of fruit preservation. It also revealed a small improvement in thermal stability and tensile strength. The small water contact angle, even at low BQTA concentrations, gave BQTA\/PVA bioplastics good anti-fog performance. Based on the findings, bioplastics of BQTA\/PVA have the potential to be used to create packaging, and they can be applied as the second (inner) layer of the primary packaging to protect food freshness and nutrition due to their antioxidant activity and biocompatibility.<\/jats:p>","DOI":"10.3390\/molecules29174264","type":"journal-article","created":{"date-parts":[[2024,9,9]],"date-time":"2024-09-09T04:15:01Z","timestamp":1725855301000},"page":"4264","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Fabrication and Application of Tannin Double Quaternary Ammonium Salt\/Polyvinyl Alcohol as Efficient Sterilization and Preservation Material for Food Packaging"],"prefix":"10.3390","volume":"29","author":[{"given":"Laiqi","family":"Li","sequence":"first","affiliation":[{"name":"Solid-State Ion Institute, College of Chemistry and Chemical Engineering, Hu-Nan University, Changsha 410006, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wenke","family":"Zha","sequence":"additional","affiliation":[{"name":"Advanced Energy Storage Key Technology and Reliability R&D Center (AESC), School of Mechanical Engineering, Anhui Science and Technology University, Chuzhou 233100, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ximei","family":"Huang","sequence":"additional","affiliation":[{"name":"Zhongshan Nenghe Biotech Co., Ltd., Zhongshan 528400, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yangyi","family":"Gong","sequence":"additional","affiliation":[{"name":"Solid-State Ion Institute, College of Chemistry and Chemical Engineering, Hu-Nan University, Changsha 410006, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sufang","family":"Li","sequence":"additional","affiliation":[{"name":"Solid-State Ion Institute, College of Chemistry and Chemical Engineering, Hu-Nan University, Changsha 410006, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,9,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"528","DOI":"10.1038\/s41579-024-01037-x","article-title":"Microbial Food Spoilage: Impact, Causative Agents and Control Strategies","volume":"22","author":"Snyder","year":"2024","journal-title":"Nat.
