Feruloylated oligosaccharides (FOs) have been approved by the US Food and Drug Administration to be incorporated in baked goods. This research aimed to investigate the influence of FOs on flavour formation. Results revealed that the furfural content increased 5.2-, 6.7-, 5.6-, and 6.5-fold after 10 mg/g FOs was added and by 6.7-, 37.8-, 12.4-, and 64.5-fold after 50 mg/g FOs was added to aspartic acid/glucose, asparagine/glucose, glutamic acid/glucose, and dough models, respectively. Addition of FOs prevented the formation of favourable Maillard flavour compounds, such as pyrazines, maltol, nonanal, and cedrol, but produced unpleasant flavour compounds, such as dimethyl disulphide, dimethyl trisulphide, and 2-methoxy-4-vinylphenol. Our findings suggest that the addition of FOs to thermally processed food should be evaluated with caution.
