Application of a multi-toxin detect method to analyze mycotoxins occurrence in plant-based beverages

In recent years, plant-based beverages have gained popularity on the market due to environmental and ethical concerns, as well as milk intolerances and allergies. However, raw materials employed in the manufacture of these products are susceptible to mycotoxin contamination. For this reason, a new method based on a QuEChERS extraction procedure followed by ultra-high performance liquid chromatography coupled with tandem mass spectrometry (UHPLC-MS/MS) detection was developed for the analysis of 29 mycotoxins in oat, rice, soy, and almond beverages. The method was validated in terms of linearity, detection and quantification limits, matrix effect, recoveries, accuracy and precision. Satisfactory performance characteristics were achieved, with recoveries above 70% for most mycotoxins. Several commercial samples were analyzed, aflatoxins were frequently detected in rice and almond beverages, while T-2 and HT-2 toxins were identified in oat-based products. In addition, emerging mycotoxins such as enniatins and beauvericin were detected in the four types of beverages.

Plant-based beverages have become popular in recent years due to environmental and ethical concerns, as well as milk intolerances and allergies. However, the raw materials used to make these beverages are susceptible to mycotoxin contamination. Researchers have developed a new method for analyzing mycotoxins in oat, rice, soy, and almond beverages, and found that several types of mycotoxins are present in these products.
