Abstract:
Activity-guided fractionations, combined with taste dilution analyses (TDA), were performed to locate the key compounds contributing to the bitter off-taste of pea protein isolates (Pisum sativum L.). Purification of the compounds perceived with the highest sensory impact, followed by 1D/2D NMR, (LC-)MS/MS, LC-TOF-MS and MSE experiments, led to the identification of 14 lipids and lipid oxidation products, namely, 9,10,13 trihydroxy¬octadec 12 enoic acid, 9,12,13 trihydroxy-octadec 10 enoic acid,...     »
