摘要： Edible oil safety impacts food safety and consumer health. The typical pollutants-aflatoxin B1 (AFB1) and benzo (alpha)pyrene (BaP), and kitchen waste oil-are significant hazards in edible oil consumption. Herein, we developed a dual-readout lateral flow immunoassay (tdLFIA) for the multi-quantitative detection of AFB1, BaP and capsaicin (CAP). A novel monoclonal antibody against BaP was developed with a sensitivity of 1.92 ng/mL. Subsequently, gold nanoparticles and Eu3+ labelled fluorescent nanospheres were synthesized as colorimetric and fluorescent sensors. A rapid synchronous pretreatment method based on immunomagnetic beads(IMAB) combined with a molecularly imprinted solid phase extraction (MISPE) was developed. The tdLFIA enabled a rapid response of 7 min for AFB1, BaP and CAP detection, with quantitative limits of detection of 0.003, 0.6, and 0.01 ng/mL, respectively. The proposed strategy indicated reliability and has been applied in real samples, providing useful products for evaluating edible oil quality and safety.
