“…Polysaccharide-based biopolymers such as chitosan, starch, agar, carrageenan, cellulose derivatives, and proteins such as gelatin and corn zein are the most widely studied due to their excellent film formability and suitable structure as solid support materials for the fabrication of pH indicators. , Besides, many useful biopolymers can be obtained from agricultural industry by-products, an added benefit of following the zero waste principle . For example, by-products of the seafood industry such as gills, skins, trimmings, and crustacean shells can be used for chitin and chitosan production. , On the other hand, fruit and vegetable processing wastes such as seeds, husks, stems, debris, and pomaces are a rich source of pectin and cellulose. , In addition, plentifully available algal seaweeds can be used to produce biopolymers such as alginate, carrageenan, and agar with high potential in food packaging applications. − The vital properties, such as nontoxicity, biocompatibility, and biodegradability, and film formation make biopolymers a suitable alternative for active and intelligent packaging development. However, their relatively low integrity, barrier properties, and mechanical properties have limited practical applications.…”

This review covers the latest research done in biopolymer-based pH-responsive color indicators integrated with natural colorants for real-time monitoring of packaged food quality. The pH-dependent color change of various natural food colorants and the structural change of colorants at different pH values were described. Recent developments in the fabrication of pHresponsive color indicator films prepared by immobilizing natural food colorants obtained from various plant sources into different biopolymer substrates are discussed. Their applications on different food types, including meat, seafood, and dairy products, have been reviewed. They show clear and noticeable color changes with variation in the pH of the food that indicates the degree of deterioration over time. Subsequently, besides the problems faced by natural food color-based indicators, the discussion of commercial pH indicators has also been highlighted.

“…It was also tested for Cr(VI) measurement in tap water with a recovery ranges from 80% to 97%. In the same context, natural polysaccharides prepared from agar and carrageenan were deposited by layer by layer self-assembly process alternating with polyaniline onto the surface of tin-doped indium oxide [ 1 ]. The prepared film showed improved electrochemical stability of the polyaniline in acid medium owing to the antioxidant activity of the employed agar and carrageenan.…”

The extensive use of chromium by several industries conducts to the discharge of an immense quantity of its various forms in the environment which affects drastically the ecological and biological lives especially in the case of hexavalent chromium. Electrochemical sensors and biosensors are useful devices for chromium determination. In the last five years, several sensors based on the modification of electrode surface by different nanomaterials (fluorine tin oxide, titanium dioxide, carbon nanomaterials, metallic nanoparticles and nanocomposite) and biosensors with different biorecognition elements (microbial fuel cell, bacteria, enzyme, DNA) were employed for chromium monitoring. Herein, recent advances related to the use of electrochemical approaches for measurement of trivalent and hexavalent chromium from 2015 to 2020 are reported. A discussion of both chromium species detections and speciation studies is provided.

“…Stable biopolymer dispersions combined with nanomaterials are a viable alternative for modification of surface electrodes [26]. These biofilms have interesting features like low cost, great adhesion and electron transfer enabled, particularly in the use of sensors and biosensors [27,28]. Since 1986, casein (CAS) was reported as an advantageous natural polymer for food use and immobilization of enzymes in protein films prepared using transglutaminase [29].…”

Electrochemical Sensor Based on Casein and Carbon Black for Bisphenol A Detection

Bisphenol A (BPA) is an environmental endocrine disrupting chemical, which can lead to various adverse health effects. Aiming to develop effective tools for the detection of BPA, this work reports a low cost and stable film based on casein (CAS) and Carbon Black (CB). The proposed material (CAS‐CB) showed structures of CAS surrounded by CB agglomerates observed by Scanning Electron Microscopy while Fourier Transform Infrared Spectroscopy analysis illustrated characteristic bands of casein. Cyclic Voltammetry (CV) and linear sweep voltammetry (LSV) were used to investigate the electrochemical behavior of BPA using the CAS‐CB. Under optimal conditions, LSV detection presented a limit of detection of 0.25 μmol L−1 in a linear range from 0.49 to 24 μmol L−1. Additionally, the working electrode (GC) modified by the proposed film (CAS‐CB) was applied for BPA sensing in environmental and milk samples. The results showed recoveries between 95.4 to 114 % attesting the efficiency of this new material, which has simplicity in the preparation, high conductivity, and adsorption capability.
