Colorimetric Analysis of Ochratoxin A in Beverage Samples. [PDF]
Sensors (Basel), 2016 This manuscript describes the use of a portable and low cost fluorescence setup to quantify the concentration of ochratoxin A (OTA) in beverage samples using an in-house developed system and different color models. It is reported that OTA is naturally fluorescent, for that reason an ultraviolet light at 365 nm was used to excite the samples and a ...
