Detecting gluten in final rinse water samples

17 April 2017

As well as providing a rapid a test for the detection of gluten residues on food processing surfaces, Hygiena’s AllerFlow Gluten can also detect gluten in liquid samples, making it suitable for final rinse water samples. 

For food and beverage processing equipment that has been cleaned-in-place (CIP), it is often difficult to collect a sample using a swab to verify the hygienic status. Under these circumstances, a representative sample can be obtained from the final rinse water that will have been in contact with internal surfaces.

AllerFlow Gluten is designed detection of gluten as part of an allergen monitoring program. It is specific to the gliadin R12 allergenic fraction found in wheat, barley and rye, with no cross reactivity with soy, rice or corn.  The combination of its patented snap valve technology for convenient sample collection devices and classical lateral flow technology is said to make gluten testing easy. Simply swab, snap and pour the fluid into the sample fill aperture on the cassette.

The result is available in 10 minutes where a pass is indicated when a single blue line appears, meaning that the sample contains less than 5 parts per million (ppm) gluten. If the samples indicate greater than 5ppm gluten, a red line appear on the cassette.
