Difficulty in identifying the presence of formalin with the naked eye can make people restless and harmed. The dangers of formaldehyde to human health require us to be able to know whether or not there is formalin content which is generally used to preserve food. Formaldehyde in food is fast and easy.

With the method, it can be known practically formalin abuse in food.
