Description
Rye and barley breads are produced by lactic‑acid fermentation that develops flavor, acidity, and a characteristic crumb structure.
Technical
During fermentation, Lactobacillus species produce lactic and acetic acids while yeast generates CO₂ and ethanol. The acids lower the pH to 3.5–4.6, promoting starch gelatinization and a weak protein network in rye, while malted barley supplies β‑amylase to release fermentable sugars. The combined microbial activity and acid environment yield the dense, chewy texture and complex flavor profile of traditional rye and barley breads.
