What are the most common Food Analysis assays performed on a microplate reader?
Using a BMG LABTECH FLUOstar OPTIMA, Dr. Ron Prior at the University of Arkansas adapted the ORAC assay to the microplate format. Now it is used by thousands of food scientists to determine the antioxidant capacity of any food or biological substance.
The Free Amino Nitrogen (FAN) assay using ninhydrin is another commonly used food analysis assay that has just been adapted to the microplate format. The FAN assay measures the amount of usable protein or nitrogen that is available in food and beverage products for yeast to ferment. Dr. Gary Spedding and colleagues miniaturized the FAN assay on the SPECTROstar Nano, making it more reliable while using less material.
