specific Embodiment 1

[0020] This embodiment is an embodiment of a Sudan Red detection device.

[0021] The Sudan red detection device of the present embodiment, structural schematic diagram is as figure 1 shown. Along the direction of light transmission, the device is sequentially equipped with a laser 1 in the ultraviolet band, a two-dimensional scanning galvanometer 2, a scanning lens 3, a first aperture 4, an imaging lens 5, a beam splitter 6, a second aperture 7, an objective lens 8, and a Object and UV glue mixture 9, tube mirror 10 and image sensor 11; the light beam emitted from laser 1 is reflected by two-dimensional scanning galvanometer 2, then passes through scanning lens 3, first aperture 4, imaging lens 5, beam splitter in sequence 6. The second aperture 7 and the objective lens 8 are irradiated onto the surface of the mixture 9 of the object to be measured and the UV glue, and the light beam diffusely reflected by the surface of the mixture 9 of the object to be measured and the UV ...

specific Embodiment 2

[0022] This embodiment is an embodiment of the Sudan Red detection method.

[0023] The Sudan Red detection method of this embodiment is realized on the Sudan Red detection device of the specific embodiment 1. The method includes the following steps:

[0024] Step a, mixing the food to be tested and the UV glue at 45-65 degrees Celsius to obtain a mixture 9 of the food to be tested and the UV glue;

[0025] Step b, place the food to be tested and the UV glue mixture 9 on the front focal plane of the objective lens 8, and set the number of step rotations in the two rotation directions of the two-dimensional scanning vibrating mirror 2 to be N respectively x and N y ;

[0026] Step c, the number of step rotations N of the two rotation directions set according to step b x and N y , place the 2D scanning galvanometer 2 at N x ×N y different spatial positions, image the food to be tested and the UV glue mixture 9 at each spatial position, and obtain N x ×N y images;

Abstract

The invention belongs to the technical field of food detection and relates to a Sudan red detection device and method. The device is orderly provided with an ultraviolet band laser, a two-dimensional scanning galvanometer, a scanning lens, a first diaphragm, an imaging lens, a spectroscope, a second diaphragm, an objective lens, a detected object-UV glue mixture, a tube lens and an imaging sensor along a light transmitting direction. The method comprises preparing the detected object-UV glue mixture, designing motion parameters of the two-dimensional scanning galvanometer to obtain multiple images, calculating C and determining if the detected object contains Sudan red. The Sudan red-UV glue compound can produce a crystal structure with optical anisotropy and can produce obviously different light reflecting characteristics under irradiation of UV lights at different angles. Based on the above characteristics, the invention discloses the Sudan red detection device and method. The device has a simple structure. The method has a simple detection process. The method and device are suitable for ordinary people-based operation.

Description

technical field [0001] The invention belongs to the technical field of food detection, and in particular relates to a Sudan red 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 for Sudan Red incl...
