Background Due to biomaterials' biodegradable, biocompatible, sustainable, and renewable
nature, there is growing interest in develo** biopolymer-based food packaging films …

Tannic acid (TA), a natural polyphenol, is a hydrolysable amphiphilic tannin derivative of
gallic acid with several galloyl groups in its structure. Tannic acid interacts with various …

Chitosan (CS) has been extensively studied because of its biocompatibility,
biodegradability, low toxicity, and good film-forming properties. However, pristine CS has …

As a phenolic acid, tannic acid can be classified into a polyphenolic group. It has been
widely studied in the biomedical field of science because it presents unique antiviral as well …

Polysaccharides and proteins are important macromolecules for develo** hydrogels
devoted to biomedical applications. Chemical hydrogels offer chemical, mechanical, and …

Natural polysaccharides are being studied for their biocompatibility, biodegradability, low
toxicity, and low cost in the fabrication of various hydrogel devices. However, due to their …

Antioxidant and pH-sensitive chitosan based films were developed by incorporating different
amounts of black soybean seed coat extract (BSSCE). Spectroscopic analysis showed the …

Chitosan packaging has been widely studied for food preservation, the application of which
is expanded by the incorporation of tea polyphenols. This paper reviews the influence of tea …

Currently used approaches for biopolymer modification are either expensive, poisonous or
do not lead into the well-desired characteristics to the final film materials. Development of …

This study investigated the potential of chitosan/PVA films containing black carrot
anthocyanins as a natural pH indicator and bentonite as a nano-filler, for intelligent …
