contrast<br>For the detection of tyrosinase, a variety of methods have been developed. It is mainly based on fluorescence, colorimetry and electrochemistry. The detection limits and characteristics of the methods proposed in the literature and electrochemical methods in this paper are shown in Table 3. It can be seen from table 3 that compared with the traditional fluorescence method and colorimetric method, this experimental method has certain advantages in terms of accuracy, cost-effectiveness and stability, and [(PSS / PPy) (p2mo18 / PPy) 5] composite multilayer film modified electrode has lower detection limit for tyrosinase detection, which can be used as a rapid screening method or for on-line detection of tyrosinase content to realize the detection of tyrosinase Study on the quality of aquatic products or monitor the freshness of aquatic products.<br>
