Understanding Lactic Acid Bacteria (LAB)
Lactic acid bacteria (LAB) are a group of beneficial microorganisms that play a crucial role in the fermentation of milk. They convert lactose (milk sugar) into lactic acid, which contributes to the curd formation in dairy products.
Conversion of Milk to Curd
- LAB ferment lactose, producing lactic acid.
- This acidification causes milk proteins to coagulate, forming curds.
- The process also gives yogurt and cheese their characteristic tangy flavor.
Nutritional Enhancement by LAB
LAB not only transform milk into curd but also enhance its nutritional profile.
- They play a vital role in synthesizing certain vitamins, especially from the B complex group.
- Among these, Vitamin B12 is particularly important for various bodily functions.
Importance of Vitamin B12
- Vitamin B12 (cobalamin) is essential for red blood cell formation, neurological function, and DNA synthesis.
- It is predominantly found in animal products, making it crucial for vegetarians or those with limited dietary sources of this vitamin.
Conclusion
Through the fermentation process, LAB not only convert milk into curd but also enrich it with Vitamin B12, making dairy products a valuable source of this essential nutrient, especially for populations at risk of deficiency. Thus, the correct answer to the question is option ‘D’—Vitamin B12.
