Polyurethane Application to Transform Screen‐Printed Electrode for Rapid Identification of Histamine Isolated from Fish

Scientifica, Volume 2023, Issue 1, 2023., 2023
The toxicity of histamine has attracted numerous researchers to develop a method for histamine determination purposes. The Food and Drug Administration (FDA) unequivocally prohibits the consumption of histamine above 50 mg·kg−1. Thus, an innovation in histamine detection in fish has been developed in this research.
