Chemical Changes During Fermentation
As milk undergoes fermentation, various chemical changes occur that contribute to the final characteristics of sour milk. The primary reaction is the conversion of lactose into lactic acid, as mentioned before, but this is supported by several other reactions.
One crucial transformation is the denaturation of whey proteins. As the acidity increases, the proteins in milk begin to unfold and aggregate. This process plays a role in thickening the milk and forming a gel-like consistency. Not only does this affect texture, but it also promotes the development of unique flavors.
Additional Changes Include:
- Production of vitamins: Fermented milk can be enriched with various vitamins, especially B vitamins.
- Formation of peptones: This enhances digestibility, making nutrients more available for absorption.
