The baker's yeast enzyme maltase converts maltose into glucose, invertase converts any added sucrose to glucose and fructose, and zymase converts glucose and fructose to carbon dioxide gas which makes the dough rise, and alcohol which gives the baked bread flavor. Sourdough starters also produce lactic and acetic acids, further contributing to ...
Making bread in the summertime is a real joy. The warm, humid temperatures help dough rise beautifully. But in winter, it can be a real bear to get the lift you need in a cooler home.
The gas produced is often carbon dioxide, or occasionally hydrogen. [1] When a dough or batter is mixed, the starch in the flour and the water in the dough form a matrix [2] (often supported further by proteins like gluten or polysaccharides, such as pentosans or xanthan gum). The starch then gelatinizes and sets, leaving gas bubbles that remain.
Saccharomyces cerevisiae, the yeast commonly used as baker's yeast. Gradation marks are 1 μm apart.. Baker yeast is the common name for the strains of yeast commonly used in baking bread and other bakery products, serving as a leavening agent which causes the bread to rise (expand and become lighter and softer) by converting the fermentable sugars present in the dough into carbon dioxide and ...
A dough conditioner, flour treatment agent, improving agent or bread improver is any ingredient or chemical added to bread dough to strengthen its texture or otherwise improve it in some way. Dough conditioners may include enzymes , yeast nutrients, mineral salts, oxidants and reductants , bleaching agents and emulsifiers . [ 1 ]

Staling is a chemical and physical process in bread that reduces its palatability.Staling is not simply a drying-out process caused by evaporation. [1] One important mechanism is the migration of moisture from the starch granules into the interstitial spaces, degelatinizing the starch; stale bread's leathery, hard texture results from the starch amylose and amylopectin molecules realigning and ...
The Chorleywood bread process (CBP) is a method of efficient dough production to make yeasted bread quickly, producing a soft, fluffy loaf. Compared to traditional bread-making processes, CBP uses more yeast, added fats, chemicals, and high-speed mixing to allow the dough to be made with lower-protein wheat, and produces bread in a shorter time.
