Foreign body identification
A foreign body is an unwanted physical object present in a food or drink product. Here at Campden BRI we have a dedicated Microscopy team who are able to identify many different types of foreign bodies, using our extensive expertise, techniques and suite of state-of-the-art equipment listed below.
Techniques and equipment
Light microscopy – stereo and compound microscopes
Stereo Microscope – Used to assist with visualising minute detail and gain a detailed view of the foreign body.
Compound Microscope – Commonly used to identify organic matter and surface deposits removed from a foreign body which may indicate contact with a product.
A non–destructive technique which allows the elemental composition of a sample to be identified. Elemental composition is a key feature in identifying a wide range of samples. In addition to determining the elemental composition of a sample, the Carl Zeiss Evo 60 Scanning Electron Microscope, alongside the x-ray analyser can be used to map the distribution of elements over an area of a sample.
Fourier Transform InfraRed spectroscopy (FT–IR)
A technique which produces a spectrum of infrared absorption of a sample when an infrared beam is projected onto it. This spectrum is then compared against a vast library of reference data.
Heat processing of many animal/insect samples can denature enzymes within the tissues of the sample. A phosphatase test is a chemical test which aims to identify whether the phosphatase enzyme, is active or if has been denatured due to heat processing.
A chemical test can be used to determine the presence of peroxidase-like activity, which is exhibited by the haemoglobin of all red blood cells. This test will give a presumptive result for the presence of blood.
