Abstract
The present disclosure belongs to the technical field of rapid detection of foods, and relates to a preparation method and use of a metal-organic frameworks (MOFs)-based composite pretreatment material for eliminating capsaicin (CAP) interference. First, preparing an metal-organic frameworks suspension; adding ammonia water to an iron salt solution, centrifuging, washing, drying and redispersion to obtain a magnetic nanoparticle suspension; mixing with the metal-organic frameworks suspension and heating, centrifuging, washing, drying and redispersion to obtain a magnetic material-modified metal-organic frameworks solution; adding an amidated polysulfone solution, preparing the resulting mixed solution into a droplet, and solidifying the droplet in water to obtain the MOFs-based composite pretreatment material. The MOFs-based composite pretreatment material can be used in capsaicin interference-resistant detection of a numbing substance in a spicy hot pot soup base.
