Letâs have a look at the different reactions that can be associated with bread intolerance and whether giving up bread can be justified. The staple ingredients of bread are flour, usually wheat flour, and yeast. Wheat and yeast can cause allergies, immediate severe reactions that can be potentially fatal. However, food allergies are rare with only about 2% of adults suffering overall.
Lactic acid fermentation is a biological process by which glucose and other six-carbon sugars (also, disaccharides of six-carbon sugars, e.g. sucrose or lactose) are converted into cellular energy and the metabolite lactate.
Alcohol fermentation is the formation of alcohol from sugar. Yeast, when under anaerobic conditions, convert glucose to pyruvic acid via the glycolysis pathways, then go one step farther, converting pyruvic acid into ethanol, a C-2 compound.Fermentation of ethanol.lcohol fermentation is the formation of alcohol from sugar.
