Lipoxygenase activity in wholemeal flours from Triticum monococcum, Triticum turgidum and Triticum aestivum

► LOX activity was assessed in 57 accessions of three Triticum species. ► pH optima and kernel fractions distribution were also studied. ► LOX activity ranking was Triticum aestivum > Triticum turgidum > Triticum monococcum. ► All einkorns and some emmer and durum accessions showed low LOX activities. ► LOX activity was maximum at pH 5-6 and was higher in the germ followed by the bran and endosperm.
