Description

This work describes a rapid sample preparation coupled with independent fluorescence detection for ochratoxin A determination in red wine
samples, which has been proven to have the advantages of low solvent consumption, high recovery efficiency and user-friendly operating
processes. The validated linear detection range was from 12.5 ppb to 200 ppb with a R2 coefficient of 0.9959. The limit of detection is 50.7 ppb,
which needs further optimisation to reach the maximum acceptable limit regulated by European Commission (2 ppb).
