Co z Fermentationem i Dairy?

Nie ma to jak w przypadku środowiska naturalnego, fermentation is thee metabolic conversion of milk constituents - primaryly lactose, thee natural sugar in milk - into organic acids, gases, and tell compounds by select microorganisms. Thee mott pathway is homolactic fermentation, where lactic acid bacteria (LAB) convert lactose into lactic acid. This acquification lowers te milk 's pH, causiing casein casein proteins tone and me form a gele netk.

Beyond lactic acid, secondary metabolites ike diacetyl, acetaldehyde, and carbon dioxide contribute to o flavor and texture. For example, diacetyl imports a mately note in sour cream and certain cheeses, while acetaldehyde is a key flavor contribuent in yogurt. The interplay of these compounds defenes thee product 's identity.

The Science Behind Lactic Acid Fermentation

Lactic acid fermentation is a form of anaerobic respiration. The bacteria breake down lactose (a disaccharite of glucose and galaktose) via glycolysis, ultimately producing two contriules of lactic acid per dispaule of lactose. This reactionon lowers the pH from around 6.6 (fresh milk) to compatiately two 4,5 or lower, dependin thee product.

To ensure robutt fermentation, starter cultures are carefuly selected andd added in specific concentrations.
