WebFactors affecting titratable acidity in raw milk Abstract The value of titratable acidity (TA) as an indicator of raw milk quality has been challenged recently, because milk is refrigerated within minutes after it leaves the cow until it reaches the consumer. Also, high milk protein may interfere with the test or confer falsely high TA values. WebBoth titratable acidity (TA) and pH are measures of acidity, but for most process control purposes, pH is a more useful measurement. Some cheese makers, however, still use TA …
