Suitability of TEMPO-oxidized oat β-glucan for noodle preparation

Native oat β-glucan (N-BG) and the oxidized derivative β-glucan (Oxi-BG) were incorporated into noodles and preparation characteristics (pasting, cooking, and textural properties) were investigated. N-BG caused an increase in the pasting parameters of wheat flour, and values were increased by Oxi-BG. Noodles containing either N-BG or Oxi-BG had higher cooked weights, cooked volumes, and water absorption values than controls. Raw noodles containing either N-BG or Oxi-BG showed high L values. Cooked noodles lacking BG exhibited higher L values. N-BG-containing noodles had textural properties similar to controls. Noodles prepared with Oxi-BG had higher textural parameter values than N-BG noodles, except for hardness.
