POST-ACIDIFICATION ACTIVITY OF STARTER CULTURES OF LACTOCOCCUS AND STREPTOCOCCUS THERMOPHILUS

Abstract

Studies were conducted to investigate changes in active acidity (pH) in milk samples fermented with strains of Lactococcus and Streptococcus thermophilus under different storage temperature regimes (+4°C, +8°C, and +12°C). It was established that +12°C represents a critical storage temperature, at which the active acidity decreased to pH 4.4 and below in all examined samples by the 7th day of storage. No statistically significant relationship was found between the decrease in active acidity and the saccharolytic profile of Streptococcus thermophilus cultures used for milk fermentation.
