In general terms, pasteurized soymilk presented higher bacterial counts compared to UHPH soymilks. From day 1 to day 14, mesophilic bacteria increased progressively in pasteurized and 200 MPa, 55 °C soymilks, but beyond this point an accelerated increase occurred mainly in pasteurized soymilk. In parallel with bacterial growth, pH values of pasteurized sample decreased considerably after 14 days of storage (Fig. 1C).
