This research aims to improve methods for identifying illegal cooking oils using advanced spectroscopy techniques.
Utilized surface enhanced Raman spectroscopy for analysis of oils.
Applied acyl nucleophilic substitution reaction to facilitate detection.
Focused on the detection of capsaicin as a marker for illegal cooking oil.
Successfully identified various illegal cooking oil samples based on capsaicin presence.
Demonstrated high sensitivity and specificity in detecting the target substances.
Abstract
Accurate discrimination of illegal cooking oil (ICO) remains a conundrum in the fields of analytical chemistry and food safety. Nevertheless, capsaicin can be regarded as a highly valuable exogenous signal...
