hey everyone 🙂
does anyone know why sourdough bread is sour? or what makes it different to regular bread?
In addition to yeast (Saccharomyces), sourdough bread also uses Lactobacillus plantarum which results in a pleasantly sour taste. The lactic acid (formed by Lactobacillus plantarum) also lower the pH (in other word- makes it more acidic), which inhibits the amylase enzyme in the flour from breaking down starch into the sweeter-tasting maltose. That’s why it is less sweet 🙂
