Recent advances in protein-polysaccharide based biocomposites and their potential applications in food packaging: A review.

This review addresses the current trend of replacing petroleum-based polymers in food packaging with bio-based alternatives, specifically focusing on proteins and polysaccharides. While these biopolymers exhibit excellent film-forming properties and are abundant in nature, their individual use in packaging lacks ideal plastic-like characteristics, especially in terms of mechanical and barrier properties. A recent solution involves the formulation of biocomposites through the reinforcement of one biopolymer with another (e.

Study on the characteristics of gluten/alginate-cellulose/onion waste extracts composite film and its food packaging application.

The study aimed to improve the properties of SA-CMC film by gluten (G) blends and bioactive compounds from onion waste extracts (OWEs) peel (OPE) and stalk (OSE). The applicability of film on the quality of peeled shallot onion during storage was also examined. Water barrier (0.

Development of active packaging film from sodium alginate/carboxymethyl cellulose containing shallot waste extracts for anti-browning of fresh-cut produce.

Owing to growing concerns about making pollution-free sustainable environment by reducing the dumping of agricultural waste and convert it into valuable product is a key to carry out the present study. The ultimate goal of this study is to convert shallot onion wastes (SOWs) into active packaging and evaluating the anti-browning effect due to the SOWs holding rich polyphenols and antioxidants. The active packaging film was fabricated by using sodium alginate (SA) and carboxymethyl cellulose (CMC) along with shallot onion waste extract (SOWEs) such as peel and stalk at 0.

Polypyrrole and enzyme free cholesterol flakes based composite: Selective determination of theophylline.

In the present work, we demonstrated the non-enzymatic theophylline (TP) detection using nanostructured Polypyrrole (Ppy) and Cholesterol (Ch) flakes coordinated nanocomposite coated on Glassy Carbon Electrode. The higher active surface area and good mechanical stability of the Ppy integrated Ch composite exhibited better oxidation towards TP. The electron transfer across hydrogen bonding is of fundamental importance in enhancing the biochemical process in this biosensor system.
