Why Does Sour Cream Have a Sharp, Tart Flavor

Question

Why does sour cream have a sharp, tart flavor
A) from the ADP produced by microbes during glycolysis
B) from the lactic acid, produced anaerobically by microbes
C) from the ethyl alcohol formed as the cream is broken down by microbes
D) from the citric acid released by microbes during the citric acid cycle

Accepted Answer

Sour cream gets its sharp, tart flavor from the lactic acid that is produced during anaerobic fermentation of the cream by microbes. This process is also responsible for the thick texture of sour cream.
