Assertion: Dough used for making food such as dosa and idli is fermented by bacteria.
Reason: The puffed-up appearance of dough is due to the production of lactic acid.
Explanation:
- Fermentation of dough: The dough used for making food items like dosa and idli undergoes a process called fermentation. This fermentation is carried out by bacteria. The most common bacteria involved in this process are lactic acid bacteria, particularly species of Lactobacillus.
- Role of bacteria: These bacteria convert the carbohydrates present in the dough into lactic acid through a process called lactic acid fermentation. The bacteria metabolize the carbohydrates and produce lactic acid as a byproduct.
- Production of lactic acid: Lactic acid production is one of the key metabolic activities of lactic acid bacteria. The bacteria convert the glucose present in the dough into lactic acid, which gives the dough its characteristic tangy flavor.
- Puffed-up appearance: The puffed-up appearance of dough, which is observed in food items like dosa and idli, is primarily due to the production of carbon dioxide gas during fermentation. The lactic acid bacteria produce carbon dioxide gas as a metabolic byproduct. This gas gets trapped within the dough, causing it to rise and become fluffy.
- Conclusion: Therefore, the assertion that dough used for making dosa and idli is fermented by bacteria is correct. However, the reason that the puffed-up appearance of dough is due to the production of lactic acid is incorrect. While lactic acid is produced during fermentation, the puffed-up appearance is primarily attributed to the production of carbon dioxide gas.
