Sourdough is a stable culture of lactic acid bacteria and yeast in a mixture of flour and water.

Major lactic acid bacteria in sourdough are heterofermentative organisms and convert hexoses by the Phosphoketolase pathway to lactate, CO2 and acetate or ethanol; [63] heterofermentative lactic acid bacteria are usually associated with homofermentative lactobacilli, particularly Lactobacillus and Companilactobacillus species. ga('set', 'dimension2', "entryex"); II. bids: [{ bidder: 'rubicon', params: { accountId: '17282', siteId: '162036', zoneId: '776160', position: 'atf' }}, iasLog("criterion : cdo_ei = sourdough"); {code: 'ad_btmslot_a', pubstack: { adUnitName: 'cdo_btmslot', adUnitPath: '/2863368/btmslot' }, mediaTypes: { banner: { sizes: [[300, 250]] } }, { bidder: 'ix', params: { siteId: '195465', size: [300, 250] }}, { bidder: 'appnexus', params: { placementId: '11653860' }}, Because the rise time of most sourdough starters is longer than that of breads made with baker's yeasts, sourdough starters are generally unsuitable for use in a bread machine. storage: { If the fermenting dough gets too warm, the yeasts slow down, producing less fructose. Definition of sourdough. [23][24][25][26][27] C. milleri can grow under conditions of low pH and relatively high acetate levels, a factor contributing to sourdough flora's stability. [89][90], Sourdough bread has a relatively low glycemic index compared with other types of bread. The lowered pH of a sourdough starter, therefore, inactivates the amylases when heat cannot, allowing the carbohydrates in the bread to gel and set properly. { bidder: 'ix', params: { siteId: '195464', size: [120, 600] }}, pbjs.que.push(function() { sourdough.
