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 first diaphragm 4 and an objective lens 5; the light beam emitted from the linear array LED array 1 passes through the imaging lens 2 and the dichroic prism 3 1. After the objective lens 5, it is irradiated in parallel to 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 rotate 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 the optimum angle, light up each LED in the linear array LED array 1 in turn, and adjust the angle of the one-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 imag...

Abstract

The invention relates to a Sudan red ultraviolet curing detection device and method; the lighting optical path of the device includes a linear array LED array in the ultraviolet band, an imaging lens, a beam splitting prism, a first aperture and an objective lens; the imaging optical path includes a mixture of food to be tested and UV glue Body, objective lens, first diaphragm, beam splitter, tube mirror, second diaphragm, scanning lens, one-dimensional scanning galvanometer, focusing lens, pinhole and detector; the method first obtains the food to be tested and the UV glue mixture , and then turn on each LED in the linear array LED array in turn to obtain multiple images. By calculating the gray value, it can be concluded whether Sudan red is contained; An optically anisotropic crystal structure, under the irradiation of ultraviolet light at different angles, the crystal will have significantly different reflective properties. Based on the above characteristics, a Sudan red ultraviolet curing detection device and method are disclosed. The instrument structure is simple and the detection process is simple. Simple, ordinary people can operate.

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...
