specific Embodiment 1

[0026] This embodiment is an embodiment of a Sudan Red detection device based on ultraviolet curing.

[0027] The Sudan red detection device based on ultraviolet curing of this 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: an area array LED array 1 in the ultraviolet band, an imaging lens 2, a dichroic prism 3, a first diaphragm 4 and an objective lens 5; the light beam emitted from the area array LED array 1 passes through the imaging lens 2 and the dichroic prism 3 , behind the objective lens 5, parallel irradiation onto the surface of the food to be tested and the UV glue mixture 6;

[0029] The imaging optical path is as image 3 As shown, it includes: food to be tested and UV glue mixture 6, objective lens 5, first aperture 4, beam splitting prism 3, tube mirror 7, second aperture 8, scanning le...

specific Embodiment 2

[0032] This embodiment is an embodiment of a method for detecting Sudan Red based on ultraviolet curing.

[0033] The Sudan red detection method based on ultraviolet curing of the present embodiment is realized on the Sudan red detection device based on ultraviolet curing of 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, turn on each LED in the area array LED array 1 in turn, and adjust the angle of the two-dimensional scanning galvanometer 10 accordingly, so that the surface information of the food to be tested and the UV glue mixture 6 is received by the detector 13, and the number of LEDs is obtained. the same image;

[0037] Step d, extract the gray value of the...

Abstract

The invention relates to a tony red detection device and method based on ultraviolet curing. An illuminating light path of the device comprises an area-array LED array at the ultraviolet band, an imaging lens, a beam splitter prism, a first diaphragm and an objective lens. An imaging light path comprises a mixture of food to be detected and UV glue, an objective lens, a first diaphragm, a beam splitter prism, a tube mirror, a second diaphragm, a scanning lens, a two-dimensional scanning galvanometer, a focusing lens, a pinhole and a detector. The method includes the steps that the mixture of food to be detected and UV glue is obtained first; then all LEDs in the area-array LED array are lightened in sequence, a plurality of images are obtained, and accordingly C is calculated; at last, the conclusion about whether tony red is contained or not is drawn. It is discovered that after the tony red is combined with the UV glue, an optically-anisotropic crystal structure can be generated, and the crystal can have an obviously-different light reflecting character under the radiation of ultraviolet light at different angles. On this basis, the tony red detection device and method based on ultraviolet curing are disclosed, the structure of the device is simple, the detection process is easy, and the process can even be operated by common people.

Description

technical field [0001] The invention belongs to the technical field of food detection, and in particular relates to a detection device and method for Sudan red based on ultraviolet curing. 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 dete...
