Determination of Lactic Acid in Cheddar Cheese and Calcium Lactate Crystals

Walter V. Price, Cheese Research Institute, Department of Food Science, University of Wisconsin, Madison 53706

ABSTRACT

An accurate method for the quantification of L(+)-lactic acid and D(–)-lactic acid in cheese and calcium lactate crystals found on the surface of cheese was devised through the modification of an existing L(+)-lactic acid test procedure.

The mean percentage of lactic acid recovered from standard solutions was 97.7 for L(+)-lactic acid and 99.5 for D(–)-lactic acid. When known amounts of L(+)- or D(–)-lactic acid were added to calcium lactate crystals and Cheddar cheese, a high percentage of the added lactic acid was recovered, indicating that no racemization of lactic acid occurred during the assay procedure.
