Summary The objective of this study was to investigate the characteristics of sponge cakes containing native oat β‐glucan (BG‐B) and its oxidised derivative with TEMPO (2, 2, 6, 6‐tetramethyl‐1‐piperidine oxoammonium ion) (Oxi‐B). BG‐B and Oxi‐B were substituted at 1% (w/w) into a formulation, and then the effects of BG‐B and Oxi‐B addition on the pasting properties of wheat flour and the physicochemical and textural properties of sponge cakes were determined. The pasting parameters of wheat flour were increased by BG‐B, whereas they were decreased in wheat flour with added Oxi‐B. The cake containing Oxi‐B had a lower volume, and a higher symmetry and uniformity than the BG‐B cake. The Oxi‐B cake exhibited smaller L * and b * values and a higher a * value than the control in crumb and crust colour. According to texture profile analysis, the BG‐B cake had increased hardness, chewiness and gumminess, whereas the Oxi‐B cake had decreased hardness.
