Plant-based milks: unexplored source of emerging mycotoxins. A proposal for the control of enniatins and beauvericin using UHPLC-MS/MS

Posted on 3 December, 2019 by fqm302

Mycotoxins have become one of the most common contaminants reported worldwide. Current legislation has established maximum levels only for some well-known mycotoxins; however, there are many other “emerging mycotoxins” for which there is no regulation, as enniatins and beauvericin. An … Continue reading →
