Biological leaveners (yeast) ferment sugars to produce CO2cap C cap O sub 2
This is a biochemical transformation where enzymes (amylases) break down starches into simple sugars for the yeast to consume. Temperature control is critical here to manage flavor development.
Replacing oxygen with inert gases inside packaging significantly extends shelf life without the need for heavy preservatives. Bakery Products Science and Technology
and alcohol. Chemical leaveners (baking soda/powder) trigger acid-base reactions to create lift in cakes and cookies.
Modern bakers use added enzymes (like xylanases or lipases) to improve dough handling, increase volume, and slow down staling (starch retrogradation). and alcohol
The use of gums (like xanthan or guar) helps stabilize moisture, which is especially crucial in gluten-free baking to mimic the structural properties of wheat. 4. Quality Control and Safety Commercial production relies on precise instrumentation:
Mixing isn't just about blending; it's about developing the dough's elasticity and extensibility. Modern bakeries use farinographs to measure how dough resists deformation. The use of gums (like xanthan or guar)
At the molecular level, every ingredient serves a structural or chemical purpose:
