A study was made of the composition, acidity, bacterial levels and related characteristics of 34 flavored frozen yogurts obtained in the Northeast United States from various sources.

Most brands of frozen yogurt had a pH of 4.4 or lower and a titratable acidity above 0.9% with accompanying typical flavor and tartness.
