Answers: Why does store-bought sandwich bread stay soft and last so long compared to traditional bakery bread?

• sandwich bread vs traditional bread shelf life
• science of bread mold and staling
• role of fat and sugar in soft bread
• yeast boosters and enzymes in commercial baking
• Chorleywood bread process

What it concludes

• Sandwich bread contains added fat and sugar, which provide moisture and softness without contributing water that causes mold.
• Sugar holds onto water at the molecular level, feeds the yeast, and keeps bread from drying out.
• Malted flour and calcium sulfate act as yeast boosters and buffers to maintain optimal dough pH.
• Commercial dough conditioners like vinegar and cultured wheat act as clean-label mold inhibitors.
• Amylase enzymes break down starch to keep bread from recrystallizing and staling, while ascorbic acid strengthens gluten.
• Sandwich bread is baked in pans at 92 degrees Celsius with no steam to ensure a soft crust.
