摘要

The present invention relates to a portable litmus paper for detecting a pesticide residue, and more specifically, to a portable litmus paper for detecting a pesticide residue which is able to carry, and finds out a color change in naked eyes through a simple contact with an object to be tested in order to find out whether there is a pesticide residue on surfaces of vegetables. To this end, the present invention comprises: a film which is made from paper or plastic materials whose one surface has adhesive properties; and a litmus paper which is attached to the one surface having the adhesive properties, and is a different color from the film. The film and the litmus paper are accommodated in an enclosure, and when the other surface of the litmus paper is withdrawn to be in contact with surfaces of vegetables, and reacts to pesticide ingredients remaining on the surfaces of the vegetables, the color of the litmus paper is changed, such that a user can check whether there is a pesticide residue or not.;COPYRIGHT KIPO 2018
