A simple molecularly imprinted electrochemical sensor for determination of propyl gallate in food samples

Anal Biochem. 2024 Jan 29:115477. doi: 10.1016/j.ab.2024.115477. Online ahead of print.ABSTRACTPropyl gallate (PG), a prevalent synthetic phenolic antioxidant found in food products, has generated considerable apprehension owing to its potential adverse impacts on human health. Therefore, as a result of the current inquiry, an innovative electrochemical sensor with improved sensitivity and selectivity for PG detection has been created. Under optimal conditions, the manufactured sensor exhibits the capability to identify PG within a broad range from 0.01 μM to 5 μM and from 5 μM to 1000 μM with a limit of detection (LOD) of 6 nM, demonstrating exceptional levels of reproducibility, repeatability, stability, and selectivity. The sensor demonstrated successful detection of PG in edible oils and mayonnaise, with good recoveries ranging from 98.44 % to 101.37 %.PMID:38296105 | DOI:10.1016/j.ab.2024.115477
