Embodiment 1

[0032] 1. Preparation of Chromogenic Solution

[0033] Weigh 1.6mL titanium tetrachloride, 10.0mL 37% hydrochloric acid, add water to 200mL.

[0034] 2. Assembly of Storage Tubes

[0035] Put 0.5mL of the prepared chromogenic solution into the sleeve of the storage tube, screw the flow valve into the sleeve of the storage tube, and insert the straw-type guide rod into the piston of the flow valve.

[0036] 3. Preparation of Assay Device

[0037] Put 0.1g PEG6000 into the reaction tube, and screw the storage tube and the silicone ring into the reaction tube containing the stabilizer in turn.

[0038] 4. Detection principle: First, the chromogenic solution flows out from the storage tube and enters the reaction tube; then the sample solution to be tested is also added to the reaction tube, and the original stabilizer, chromogenic solution, and sample solution in the reaction tube undergo a chemical reaction. Response, showing a color change. When the sample contains high-con...

Embodiment 2

[0043] The preparation method of this example is basically the same as that of Example 1, with the difference that: the sample taken is solid, 5 g of the sample is weighed, ground, added with 10 mL of distilled water, and soaked for 10 minutes.

Abstract

The invention relates to a rapid detecting device for detecting residual hydrogen peroxide in food, consisting of a storage tube, a silica gel ring, a reaction tube, a sucker type diversion rod, color development liquid and a stabilizer. The content of the hydrogen peroxide in food can be detected by the device; and when sample solution is added into the reaction tube, the whole reaction is a closed system and the hydrogen peroxide in a sample reacts with a reagent in the device to cause color to change, so that the content of the hydrogen peroxide in the detected sample can be semi-quantified according to the change of the color. In the detection process, the result is directly judged through the color, the operators do not contact the chemical reagent directly, the operation is simple, convenient and rapid, the sensitivity is high and the needs of field detection are satisfied.

Description

technical field [0001] The invention belongs to the field of food safety, and relates to the fields of biochemical detection and non-edible substance residue detection. Specifically, the invention relates to a detection device suitable for rapid detection of hydrogen peroxide content in food. Background technique [0002] Hydrogen peroxide solution, commonly known as "hydrogen peroxide", is a colorless, odorless liquid. Hydrogen peroxide is widely used as a strong oxidant in papermaking and textile industries, and is also used as a bactericidal disinfectant to clean wounds in hospitals. When added to food, it can be decomposed to release oxygen, and has the functions of bleaching, antisepsis and deodorization. Some foods that need to be whitened, such as: soaking hydrogen peroxide in the production process of water-fat food, shark fin, canned fruit and noodle products, etc., can improve the appearance of the product; it is forbidden to soak hydrogen peroxide in abnormally d...
