The Chemical Composition and Properties of Normal and Rancid Jersey Milk

III. Titrable Acidity, Hydrogen-Ion Concentration and Lipase Content

Department of Agricultural Chemistry Research, Oklahoma Agricultural Experiment Station, Stillwater

ABSTRACT

Data have been presented showing the titratable acidity, hydrogen-ion concentration and lipase content of the milk of animals of a Jersey herd, all of which received the same ration and were subject to the same environmental conditions. The amounts found in milk criticized as rancid have been compared with those present in normal milk of the same period of lactation.

Rancid milk was found usually to have a higher titratable acidity and hydrogen-ion concentration than normal milk of the same period of lactation. The mean titratable acidity and hydrogen-ion concentration of all rancid samples were significantly higher than the mean values for all normal samples.

All milk was found to contain a small amount of lipolytically active substance. Definitely rancid milk was somewhat more active lipolytically than was normal milk.
