[PDF] acetic acid bacteria in sourdough

There are two main acids produced in a sourdough culture: lactic acid and acetic acid. Acetic acid, or vinegar, is the acid that gives sourdough much of its tang. Giving acetic acid-producing organisms optimal conditions to thrive and multiply will produce a more tangy finished product.

  • Does sourdough have acetic acid?

    Acetic acid
    It is produced by the oxidation of ethanol by lactic acid bacteria and is the main constituent of vinegar. Acetic Acid is mainly produced in sourdough between 20°C/68°F and 25°C/77°F. Acetic acid is responsible for the tangy flavour of your sourdough or your sourdough bread.

  • What kind of bacteria is in sourdough bread?

    From these early studies, more than 50 species of lactic acid bacteria (mostly Lactobacillus spp.) and more than 20 species of yeast (mostly Saccharomyces spp. and Candida spp.) were known to be living in sourdough starters.

  • Why does my sourdough starter smell like acetic acid?

    If your sourdough starter stinks like alcohol, vinegar, or nail polish remover, it means that it's really hungry and has produced lots of acetic acid. The good bacteria have eaten up all the nutrients in the flour and are desperate to be fed.
  • Acetic acid bacteria (AAB) are commonly found in naturally fermented foods. MALDI-TOF MS facilitates the dereplication and identification of AAB. The functional role of AAB in food fermentation processes is underestimated. AAB are promising starter cultures to produce fermented foods and beverages.
