摘要

•A novel and low-cost micro-sensor was proposed based on TiO2-PANI/SFF microfiber with a diameter of 12 μm.•The response value of the micro-sensor to NH3 of 100 μg/L was 0.82 with a response time of 10 s.•Response values of the micro-sensor showed good correlation with TVB-N levels in pork (R2 = 0.990).•Discriminating accuracy of the micro-sensor for pork freshness was 86.38%.
