Abstract
We describe a method for detection of the presence of an invertebrate or an invertebrate component in a sample of substantially non invertebrate material, comprising impinging said sample with a source of electromagnetic radiation at a wavelength of at least 600 nm and detecting Raman scattering/fluorescence of said invertebrate or a component of said invertebrate at a wavenumber where the non-invertebrate components of said sample either do not fluoresce or fluoresce with sufficiently low intensity wherein the non invertebrate material is edible and/or living.

1-41. (canceled)
A method for detection of the presence of an invertebrate or an invertebrate component in a sample of substantially non invertebrate material, comprising impinging said sample with a source of electromagnetic radiation at a wavelength of at least 600 nm and detecting fluorescence of said invertebrate or a component of said invertebrate at a wavenumber where the non-invertebrate components of said sample either do not fluoresce or fluoresce with sufficiently low intensity wherein the non invertebrate material is edible and/or living.
An optical foodstuff quality control system for detecting the presence of an invertebrate or an invertebrate component in a plant-based foodstuff, the system comprising:
- a fluorescence/Raman spectrometer to remotely interrogate a fluorescence/Raman scattering response of said foodstuff;
- and
- a data analysis system, coupled to said fluorescence/Raman spectrometer, to analyse said fluorescence/Raman scattering response to determine the presence of said invertebrate/invertebrate component dependent on a level of melanin and/or melanin precursor indicated by said fluorescence/Raman scattering response.
