Why test for L-Lactic Acid?
Lactic acid is found in many food and beverages. In the wine industry, the course of malolactic fermentation is monitored by tracking the falling level of L-malic acid, and the increasing level of L-lactic acid. Lactic acid is responsible for reducing the acidity of wines providing a smoother flavour. Similarly, the quality of food produce such as baby food, meats, dairy products, fruit and vegetables and animal feed can be established by measurement of L-lactic acid content. This acid is also used and measured in the cosmetics and tobacco industry.

Testing for L-Lactic Acid
The L-lactic acid assay kit Randox Food Diagnostics supply is designed for the quantitative in vitro determination of L-lactic acid in red and white wine, beer, and fruit juices. Excellent sensitivity and inter and intra-assay precision of >5% ensures high quality dependable results. This assay is suitable for manual use or for automation on a range of analysers. The test principle is based on the following enzymatic reaction.
The amount of NADH formed in the above reaction is stoichiometric with the amount of L-lactic acid present in the sample. It is the NADH which is measured by the increase in absorbance at 340 nm. This method is specific for L-lactic acid determination. This product is currently supplied to the wine/beverage and food producers globally.
