RSSL reveals casein test breakthrough

RSSL has revealed that it has now validated a new test kit to detect the milk protein casein in highly processed foods. This is hugely significant since many of the test kits on the market can’t detect highly processed proteins, yet these proteins can still remain allergenic for susceptible individuals, says the analysis and testing company.

“Where this new ELISA test kit differs from the standard ELISA kits used for detecting milk allergens is that it involves a step to deliberately denature the proteins as part of the extraction process prior to analysis,” says RSSL food safety consultant Simon Flanagan. “The antibodies in this kit have been raised to detect these denatured proteins.”
