Specificity, simplicity and quick response of the method is most considered to choose for application in situ. This review demonstrates the potential of technological applications have so far been used in determining formaldehyde in seafood and their setbacks, disadvantages and advantages. This review is aimed to be as a reference of formaldehyde detection techniques in seafood
