The Effect of Proofing and Baking on Concentrations of Organic Acids, Carbonyl Compounds, and Alcohols in Bread Doughs Prepared from Pre-ferments.

Bread doughs prepared from pre-ferments containing 7.0% yeast and 11.9% sucrose consistently contained greater quantities of organic acids, carbonyl compounds, and alcohol than those prepared from pre-ferments with 2.4% yeast and 3.2% sucrose. After pan proof and baking, the concentrations of acids and carbonyls in bread from the richer pre-ferment were about half again as large as from the lean pre-ferment. Significant increases in concentrations of acids and carbonyls occurred both during pan proof and baking. Alcohol increased substantially during pan proof, but most of it disappeared during-baking.
