Browse the shelves of any grocery store, and you may get a false sense of security when it comes to ingredient lists. As much as consumers want to trust labels, the truth is, food products could contain mislabelled ingredients, such that they trigger an allergic reaction with serious detrimental effects including discomfort, pain sickness and in some instances, death. Manufacturers, however, do not want to risk their reputation and consumer safety over a false label. As such, there must be some sort of verification to support such an action.

How Can Food Manufacturers be Certain a Product is Free from an Allergen?There are several techniques which food testing laboratories use to screen for food allergens. PCR and ELISA are popular techniques. However, these workflows do not compare to the power of an LC-MS/MS assay. Therefore, the following application note, “Solution for Food Allergen Screening” a vMethod from SCIEX, takes allergen screening to a whole new level of detection. Unlike ELISA and PCR, this mass spectrometry-based workflow can screen 12 food allergens in one analysis and delivers high accuracy and selectivity while significantly reducing the amount of false negatives results which could trigger a product recall or worse.
The Take-Away: Reduced False-Positives When Screening Food for AllergensThis vMethod incorporates the standard operating procedure (SOP) for the extraction and analysis of specific allergens in baked and raw food products. The proprietary sample preparation protocol has been verified and tested by multiple independent laboratories. Chromatographic separation is achieved using a Phenomenex Kinetex C18 column (2.6 μm, 100 x 3 mm) column coupled with a QTRAP® 4500 Mass Spectrometer.
What you will find is that this workflow reduces false positive and false negative results through enhanced selectivity through peptide mass detection, reducing false results due to cross-reactivity or matrix effects. The performance of the method delivers a screening LOD 10 ppm in commodity.
Although food products usually label all potential allergens on the ingredients portion of the wrapper, in some cases the allergen hasn’t been declared or realized. For this reason, manufacturers take precautionary steps if they feel that there may be a risk of contamination or miss-labeling of their product1.

As analytical organizations grow, there is an even greater need to train scientists and operators more consistently to meet tight deadlines, handle increasing samples, and meet data quality expectations. A high rate of employee turnover also affects the productivity of labs worldwide. Consistent training helps today’s labs stay competitive, whether the goal is sample throughput, therapeutic development, or publication.
A few years ago, I was plotting along in my analytical job and keeping up-to-date with residue regulations took a considerable amount of time, but it was always manageable. Nowadays, we have PFAS.
Produced by certain moulds, thriving in crops such as grain, nuts and coffee, mycotoxins have contaminated agriculture and food production industries for a long time. To intensify the challenge, mycotoxins are resilient, not easily broken down and ensuring the safety of food supply chains requires comprehensive solutions and we are here to share those solutions with you.
