For the specific assay of L-lactic acid (L-lactate) in beverages, meat, dairy and food products.

INTRODUCTION:

L-Lactic acid is found in many foods and beverages. Produced
naturally by lactic acid bacteria, L-lactic acid is found in many
fermented milk products such as yogurt and cheese, and also
in pickled vegetables and cured meats and fish. It is commonly
supplemented into foods and beverages (E270) where a tart flavour
is desired, and is widely used as a non-volatile acidulant. In the egg
industry, this acid is a quality indicator, where levels above 200 mg/kg
indicate spoilage by contamination or incubation. Similarly, the quality
of milk, and fruit and vegetables, can be established by measurement
of L-lactic acid content. In the wine industry, the course of malolactic
fermentation is monitored by following the falling level of L-malic
acid, and the increasing level of L-lactic acid. In the chemical industry,
L-lactic acid is a raw material in the production of compounds such
as polylactides and biologically degradable polymers, and applications
also exist for this acid in cosmetics and pharmaceuticals.
