However, yellow alkaline noodles were lower in the improvement of texture properties than other noodles. That might be due to the addition of alkaline salt, which could have a strong structure even without steaming (Fu, 2008; Wu et al., 2006). Moreover, white salted noodles usually have a softer texture than those without salt because salt could increase non-covalent interactions and B-sheet structure in gluten proteins (Tuhumury, Small, & Day, 2014), while after 2 min, salted noodles were obviously higher than control in hardness, suggesting that steaming had an important role in product quality.
