  • Title: Chitosan/bacterial cellulose films incorporated with tea polyphenol nanoliposomes for silver carp preservation.
    Author: Zhou X, Liu X, Liao W, Wang Q, Xia W.
    Journal: Carbohydr Polym; 2022 Dec 01; 297():120048. PubMed ID: 36184184.
    Abstract:
    This study aimed to develop chitosan/bacterial cellulose-based films loaded with tea polyphenol-loaded chitosan coated nanoliposomes (CS-TP-lip) as an active agent for food preservation. The effects of the CS-TP-lip on the physicochemical properties of composite films were systematically evaluated. The CS-TP-lip exhibited spherical shapes with an average particle size of about 300 nm. Scanning electron microscopy and Fourier transform infrared spectroscopy analyses suggested high compatibility between the CS-TP-lip and film matrix through intermolecular interactions. Furthermore, due to the CS-TP-lip's presence, the elongation at break and thermal stability of the films could be enhanced to reach 75.14 ± 1.2 % and 395.33 °C, respectively, and the stability of tea polyphenol could be increased to prolong its functioning time. The films were successfully used as packaging materials for fish fillet preservation. Therefore, the developed nanocomposite films exhibit great promise as a new generation of biodegradable, sustainable, and bioactive film for food preservation.
