Fig. 2. Effect of storage at room temperature on the weight average molecular weight (Mw) (a) and solubility (b) of β-glucan in fresh oat bread extract using the shaking water bath (SWB) and the RVA digestion methods. Bread containing 0.25 g β-glucan was dispersed in 25 mL extraction buffer. Values having the same letter are not significantly different at P < 0.05.
