Investigation of volatile thiol contributions to rapeseed oil by odor active value measurement and perceptual interactions

•HS-SPME and GC-SCD method established for rapeseed thiol determination.•Four new thiols detected in microwaved rapeseed oil.•Odor activity values determined for the detected thiols.•Additive effects were explored to understand the underlying thiol behavior.•Novel insights into microwaved rapeseed oil established.
