“…Instead, over accumulation of iron can been associated with disorders (like diarrhea, anorexia, diphasic shock, metabolic acidosis, hepatitis, hemochromatosis, etc.). [7] In addition to this, iron is also widely found in nature, most commonly in natural fresh water, however excessive accumulation of iron in water can be hazardous to health and the environment. [8] Therefore, accurate monitoring of AM and iron levels are essential to control food quality and ensure consumer safety.…”

In this work, a new carbon quantum dots (CDs) was prepared though microwave assisted approach using citric acid anhydrous (CA) and N‐[3‐(Trimethoxysilyl)propyl] ethylenediamine (TPED) as raw materials. However, the CDs was not effective in actual sensing applications, so further modification of CDs was done by 3,5‐Dichloro‐2‐hydroxybenzaldehyde (it was named as G‐CDs). Fortunately, the modified CDs (G‐CDs) has good selectivity for Fe3+ and amaranth. Studies confirmed that Fe3+ could quench the fluorescence of G‐CDs by forming a complex, while the fluorescence quenching mechanism of G‐CDs by amaranth (AM) mainly belonged to the internal filtering effect (IFE). A detection limit of 20.8 nM for Fe3+ and 43.8 nM for AM were achieved. Moreover, the as‐developed G‐CDs probe was also successfully used to detect Fe3+ and amaranth in real samples, and compared with their results by the standard method, hinting that the accuracy and reliability of the probe were highly satisfactory.

“…Locust bean gum (LBG) is an optimal alternative because of the high viscosity of the solution at low concentration, as well as a safe material that exhibits biocompatibility, non-teratogenicity, and biodegradability [ 17 , 18 ]. Although LBG is easily film-forming and adherent on fruit surfaces, the poor mechanical and barrier properties are unsatisfactory for the application.…”

The application of polysaccharide-based coatings to prolong the shelf-life of fruits has attracted increasing attention. This study aims to develop a fruit coating comprising locust bean gum/carboxycellulose nanocrystals/ZnO (LCZ) blended with bayberry tannins (BT). The results revealed a significant increase from 4.89% and 11.04% to 29.92% and 45.01% in the free radical scavenging rates of 2,2-diphenyl-1-picrylhydrazyl and 2,2′-azino-di-[3-ethylbenzthiazthiazoline sulfonate] with the percentage of BT increasing from 0% to 5%, respectively. At a 5% of BT, the antibacterial activity against both E.coli and S. aureus exceeded 90% while simultaneously achieving excellent UV shielding (transmittance of 380–200 nm ≤ 0.19%). After 3 days of storage, uncoated bananas showed signs of browning, and their titratable acid and vitamin C (Vc) contents decreased from 0.57% to 0.30% and from 7.37 mg/100 g to 4.77 mg/100 g, respectively. However, bananas coated with LCZ containing 3% BT not only exhibited a better appearance, but also possessed higher titratable acid (0.44%) and Vc content (5.31 mg/100 g). This study provides a sustainable and multifunctional coating for fruit preservation.
