Detecting Toxins in Food

Nuts and FruitsAflatoxins are formed in mold within stored foods such as almonds and peanuts. Typical chromatography methods of toxin screening can be complex and time-consuming. By using a fluorescence-based system, one Ocean Optics customer now offers customers a reliable alternative to chromatography for aflatoxin detection.

Solutions in Action

The Problem: 

Contamination of peanuts with aflatoxin is carefully regulated, but monitoring in food products requires sending samples to a lab for high-performance liquid chromatography (HPLC) testing.

The Application:

Fluorescence-based detection offers a rapid, accurate alternative to HPLC detection of aflatoxin in non-lab settings. By looking at ratios of multiple fluorescence peaks, the levels of multiple mycotoxins can be assessed simultaneously.

The Solution: 

A complex optical sub-assembly to interrogate a glass capillary containing the sample. Once mounted in the customer-provided chamber, this subsystem becomes a drop-in component to the final system.


  • Optical subsystem consisting of LED illumination module, light collection and filtering optics, QE65000 spectrometer and neon wavelength calibration source
  • Automated 12-point spectrometer calibration routine run by onboard CCA
  • Custom firmware using subpixel interpolation to report values at consistent wavelengths from system to system
  • Integrated cooling system to maintain constant spectrometer temperature
