Simultaneous Measurement of L-Lactate and Ethanol in Tomato-based Products

20th July 2015

L-lactate and ethanol concentrations in complex matrices such as tomato paste and ketchup can be measured in about one minute with minimal preparation using a YSI Biochemistry Analyzer. YSI’s unique enzyme electrode technology provides for specific lactate measurements in the range of 10 to 1335 ppm.

Ethanol can be measured in the range of 20 to 1000 ppm. Measurements are virtually unaffected by color, turbidity, density, pH, or the presence of chemical substances.
