specific Embodiment 1

[0026] This embodiment is an embodiment of a Sudan red ultraviolet curing detection device.

[0027] The Sudan red ultraviolet curing detection device of the present embodiment, the structural diagram is as follows figure 1 shown. The device includes an illumination light path and an imaging light path;

[0028] The illumination light path as described figure 2 As shown, it includes: a linear array LED array 1 in the ultraviolet band, an imaging lens 2, a dichroic prism 3, a diaphragm 4 and an objective lens 5; the light beam emitted from the linear array LED array 1 passes through the imaging lens 2, the dichroic prism 3, and the objective lens in sequence After 5, parallel irradiation onto the surface of the food to be tested and the UV glue mixture 6; the linear array LED array 1 or the food to be tested and the UV glue mixture 6 rotates on its plane;

[0029] The imaging optical path is as image 3 As shown, it includes: food to be tested and UV glue mixture 6, object...

specific Embodiment 2

[0032] This embodiment is an embodiment of the detection method for Sudan red ultraviolet curing.

[0033] The Sudan red ultraviolet curing detection method of the present embodiment is realized on the Sudan red ultraviolet curing detection device of the specific embodiment one, and the method comprises the following steps:

[0034] Step a, mixing the food to be tested and the UV glue at 45-65 degrees Celsius to obtain a mixture 6 of the food to be tested and the UV glue;

[0035] Step b, placing the food to be tested and the UV glue mixture 6 on the front focal plane of the objective lens 5;

[0036] Step c. Adjust the linear array LED array 1 or the food-to-be-tested and UV glue mixture 6 to an optimal angle, and turn on each LED in the linear-array LED array 1 in turn, so that the surface of the food-to-be-tested and UV glue mixture 6 The information is all received by the line array image sensor 9 to obtain images with the same number of LEDs;

[0037] It should be noted...

Abstract

The invention belongs to the technical field of food detection, and specifically relates to a Sudan red ultraviolet curing detection device and method; the illumination light path of the device includes a linear array LED array in the ultraviolet band, an imaging lens, a beam splitting prism, a diaphragm and an objective lens; the imaging light path includes a Food and UV glue mixture, objective lens, diaphragm, beam splitter, tube mirror, linear array pinhole array and linear array image sensor; this method first obtains the food to be tested and UV glue mixture, and then sequentially lights up the linear array LED array Each LED in the LED can get multiple images, and by calculating the gray value, it can be concluded whether it contains Sudan Red; the present invention finds that after Sudan Red is combined with UV glue, it will produce an optically anisotropic crystal structure, Under the irradiation of ultraviolet light at different angles, the crystal will have significantly different reflective characteristics. Based on the above characteristics, a Sudan red ultraviolet curing detection device and method are disclosed. The instrument structure is simple, the detection process is simple, and ordinary people can operate it. technical advantages.

Description

technical field [0001] The invention belongs to the technical field of food detection, and in particular relates to a Sudan red ultraviolet curing detection device and method. Background technique [0002] Sudan red is a chemical dyeing agent, mainly used for dyeing oil paint, machine oil, wax and shoe polish and other products. Some unscrupulous traders add Sudan Red to food, such as chili powder, chili oil, red bean curd, red heart poultry eggs, etc., to make the food brighter and increase sales. However, Sudan Red is not a food additive. The chemical composition of Sudan Red contains a compound called naphthalene, which has an azo structure. The nature of this chemical structure determines that it is carcinogenic and has obvious effects on the liver and kidney organs of the human body. toxic effects. [0003] It can be seen that in order to prevent Sudan Red from harming the human body, it is necessary to detect Sudan Red in food. [0004] Traditional detection methods...
