Food detection method, and corresponding test tube for food detection

Abstract

The invention discloses a food detection method, and a corresponding test tube for food detection. The test tube for food detection comprises a tube body, a tube plug, an end cover, a stirring device, a threaded nail and a spring; the tube plug is detachably sealed at the top of the tube body, the tube plug is provided with a first cavity, and the first cavity is used for storing a reagent tank filled with detection liquid; the end cover is detachably connected to the top of the tube plug; the stirring device is arranged in the tube body, the top of the stirring device is provided with a sinking hole with an internal thread on the inner wall, and the stirring device cannot axially move and only can rotate; the threaded nail and the stirring device are coaxial, the threaded nail is located between the end cover and the tube plug, and the threaded nail can penetrate through the first cavity from top to bottom and then is inserted into the sinking hole of the stirring device; and the spring applies acting force to the threaded nail to move towards one side far away from the stirring device. During use, after the reagent tank is filled into the first cavity, the steps of adding detection liquid into the tube body and stirring can be realized at the same time by pressing the threaded nail, namely two actions are realized in one step, and the operation is very convenient.

Description

technical field [0001] The invention relates to the field of food detection, in particular to a test tube used in food detection and a detection method using the test tube. Background technique [0002] In the process of food testing, chemical methods are generally used. The testing process is as follows: [0003] First, take a certain amount of sample (solid) to be tested and put it into a beaker, then add distilled water to soak for a certain period of time to obtain a sample treatment solution; [0004] Then, take two test tubes and mark "blank" and "sample" respectively, and then take a certain amount of sample treatment solution and add them to the blank test tube and the sample test tube respectively; [0005] Afterwards, add the detection solution to the sample test tube, then close the lid and shake the solution in the sample test tube manually; [0006] Finally, the solutions in the control tube and the sample tube are poured into the cuvette, and then tested on t...

Problems solved by technology

[0007] Wherein, in the above-mentioned third step, the detection solution added to the sample test tube is added through a pipette gun, and the subsequent shaking is realized by shaking the hand-held sample test tube back and forth, so there will be the following disadvantages: (1) detection There may be deviations in the amount of liquid added. When adding the test liquid, there may be cases where the test liquid drips onto the outer wall of the test tube or the test table. The whole process is exposed to the air when the test liquid is added, so the test results may be affected by the outside The influence of factor; (2) need arm to swing back and forth when shaking well, this process is more time-consuming and laborious, and long-term reciprocation may also cause muscle soreness, although special-purpose shaking device is arranged at present (as public number or bulletin number is CN112473493A and CN207187633U Chinese patent), but this type of device belongs to a separate device, and it is necessary to fix the test tube on the device to achieve shaking, and the process is relatively cumbersome.
