What effect does excessive heat have on gluten proteins during grain processing?

• enhance elasticity

• make them tougher and more difficult to extract

What potential issue arises if -SH groups in flour are not oxidized?

• They can participate in exchange reactions with S-S groups, tightening the dough

• Protein content decreases

• The dough becomes too soft

• Gluten formation is inhibited

How do improvers or maturing agents affect flour proteins?

• Increase protein solubility

• Oxidize -SH groups to S-S groups

• Reduce S-S groups to -SH groups

• Break down protein structures
