Test paper structure for detecting cancerogenic substances in food

Abstract

The invention discloses a test paper structure for detecting cancerogenic substances in food. The test paper structure comprises a base plate, and a plurality of cutting grooves are formed in the base plate in the circumferential direction; a cover plate is mounted above the base plate, a plurality of cutting pieces corresponding to the cutting grooves are formed on the cover plate in a protruding mode in the circumferential direction, and a detection hole is formed between every two adjacent cutting pieces; an annular test paper body is mounted between the chassis and the cover plate; the test paper body is cut into a plurality of test paper blocks corresponding to the detection holes through the cutting grooves and the cutting blades; the outer diameter of the chassis is greater than that of the cover plate; and a comparison color card is adhered to the edge of the chassis. According to the invention, a piece of test paper can be quickly cut into a plurality of small blocks, so that the test paper is fully utilized, and hazardous substances can be detected for multiple times and can be detected.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a test paper structure for detecting carcinogens in food. Background technique [0002] The test paper is a kind of detection item used to detect whether the species to be detected contains the target substance. The compound contained in the long test paper can react with the target substance to produce a color reaction, and the concentration of the target substance can be roughly obtained according to the type of color. When the food is made, there are lawbreakers who will add excessive food additives, and harmful substances may also appear due to mildew and the like when the food is stored. Therefore, when food is tested, different test papers are often used to detect whether there are harmful substances in it, and the content of harmful substances. However, when the existing test paper is tested, it is usually in the shape of a strip. During the test, people crush the food, then add a ...

Problems solved by technology

However, when the existing test paper is tested, it is usually in the shape of a strip. During the test, people crush the food, then add a certain amount of water to dissolve it, then hold one end of the test paper, and put the other end into the solution, then take it out for colorimetric detection. A large part of the test paper is not used in the method, resulting in the waste of test paper

Some will also use a test card, that is, a test paper is clamped between two plates, one of the plates is open, the test chamber absorbs the solution and drips it on the test paper, and then compares the color. However, this test card can only be used once. cause waste of resources

[0003] In addition, the existing test cards can only detect one kind of harmful substance in turn, which makes it inconvenient to use
