Key Insights

• 😋 Lactic acid bacteria, specifically lactobacillus, are crucial for the fermentation process in dough making for various food items.
• 👅 Fermentation in dough results in the production of lactic acid and carbon dioxide, contributing to the taste, fluffiness, and puffiness of the final product.
• 🌱 The presence of lactic acid bacteria naturally in seeds used for dough making eliminates the need for additional starters.

Questions & Answers

Q: What role do lactic acid bacteria play in dough making?

Lactic acid bacteria, such as lactobacillus, undergo fermentation in dough, converting sugars into lactic acid and producing carbon dioxide. This contributes to the taste, fluffiness, and puffiness of the dough.

Q: How do lactic acid bacteria naturally occur in dough?

Lactic acid bacteria are naturally present in the seeds used in dough making, such as rice and urad pulse. When these seeds are ground and mixed with rice, the lactic acid bacteria initiate the fermentation process.

Q: Why does leaving the dough for fermentation for too long make it too sour?

Fermentation in dough results in the formation of lactic acid. If the fermentation process is prolonged, a larger amount of lactic acid is formed, leading to a more sour taste. Therefore, it is essential to limit the fermentation time to prevent excessive sourness.

Q: Is a starter required for dough fermentation?

Unlike in the process of curdling, where a starter is required to initiate the formation of curd, dough fermentation does not require any starter. The lactic acid bacteria naturally present in the dough ingredients initiate the fermentation process.

Summary & Key Takeaways

• Different types of dough, such as those for bakery items like cakes or breads and for dishes like idli or dosa, require different microbes for fermentation.

• Lactic acid bacteria, including lactobacillus, are the main microbes involved in the fermentation of dough.

• Fermentation results in the production of lactic acid and carbon dioxide, which contribute to the taste, fluffiness, and puffiness of the dough.
