Description

Technical Field

[0001] The invention relates to the technical field of Sudan red extraction and detection, in particular to a method for rapid extraction, purification and detection of Sudan red dye residues in food. Background Art

[0002] Sudan Red is a chemical dye, not a food additive. Its chemical composition contains a compound called naphthalene, which has an azo structure. Due to the nature of this chemical structure, it is carcinogenic and has obvious toxic effects on the liver and kidneys of the human body. Sudan Red is a chemical dye, mainly used in petroleum, motor oil and other industrial solvents to enhance their color. It is also used to enhance the gloss of shoes and floors. Also known as "Sudan", for food safety, many families need to sample and test Sudan Red in food. There are special testing instruments for Sudan Red testing, but when extracting Sudan Red from food, the process is slightly complicated and it is more troublesome for families to operate. For this reason, we propose a rapid extraction, purification and detection method for Sudan Red dye residues in food. Summary of the invention

[0003] Therefore, the purpose of the present invention is to provide a method for rapid extraction, purification and detection of Sudan red dye residues in food. Through the mutual cooperation of the rotating structure and the filtering structure, the food can be automatically scraped and filtered to dissolve the Sudan red. Moreover, through the mutual cooperation of the concentration structure and the liquid collection structure, the extract is concentrated and automatically filled and sampled. Such a structural design is suitable for home use. There is no need for manual extraction by oneself, and sampling is automatically completed, which is convenient to use.

When the entire extraction device is used for a long time, the user can directly hold the filter screen through the disassembly and cleaning port to directly take out the filter screen for replacement and cleaning.

Figure 1-5 The main part of a method for rapid extraction, purification and detection of Sudan red dye residues in food in this embodiment includes a frame assembly 100, a rotating assembly 200, a mounting assembly 300, a connecting assembly 400, a compression assembly 500, a liquid collection assembly 600 and a filtering assembly 700.

[0034] The frame assembly 100 is used to place vegetables that need to be extracted. Specifically, the frame assembly 100 includes a circular frame 110, support legs 120 fixed to the bottom surface of the circular frame 110, and a liquid outlet 130 connected to one side of the support legs 120. When in use, the support legs 120 are used for support, and the vegetables that need to be extracted are placed in the circular frame 110.

[0035] The rotating component 200 is used for rotating and scraping. Specifically, the rotating component 200 includes a rotating shaft 210 arranged in a circular frame 110, a mounting bar 220 fixed on the top surface of the rotating shaft 210, a connecting rod 230 fixed on both sides of the mounting bar 220, a raised bar 240 connected to the end surface of the connecting rod 230, and a driving motor 250 that drives the rotating shaft 210. During specific use, the driving motor 250 rotates to drive the rotating shaft 210 to rotate rapidly. During the rotation, the raised bar 240 scrapes the surface of the vegetables. After continuing to rotate for a period of time, it is allowed to stand. The liquid after standing flows into the mounting frame 310 through the liquid outlet 130.

[0036] The installation component 300 is used to install the filter component 700 for use. Specifically, the installation component 300 includes a mounting frame 310 connected to one end of the liquid outlet 130, a disassembly and cleaning port 320 opened on the top surface of the installation frame 310, and a rectangular port 330 opened on the side of the installation frame 310. During specific use, the user can disassemble, replace and clean the filter through the disassembly and cleaning port 320.

[0037] The connecting assembly 400 is used to connect the mounting frame 310 with the concentrator 510. Specifically, the connecting assembly 400 includes a connecting plate 410 covering the rectangular opening 330 and a connecting pipe 420 connected to the outer end of the connecting plate 410. When in use, the connecting plate 410 is fixed to the mounting frame 310 by bolts, and the connecting pipe 420 is connected to the concentrator 510 for liquid transportation.

[0038] The compression assembly 500 is used to concentrate the extract. Specifically, the compression assembly 500 includes a concentrator 510 connected to one side of the mounting frame 310 and a liquid outlet knob 520 disposed on the surface of the concentrator 510. During specific use, the concentrator 510 concentrates the liquid, and the user can perform liquid sampling and filling by turning the liquid outlet knob 520.

[0039] The liquid collection component 600 is used for sampling. Specifically, the liquid collection component 600 includes a material collection frame 610 connected to the bottom of the concentrator 510, a front baffle 620 connected to the front end of the material collection frame 610, a liquid storage tube 630 passing through the bottom of the material collection frame 610, and a liquid discharge tube 640 connected to the side of the material collection frame 610. During specific use, after concentration is completed, the liquid discharge knob 520 is turned, and the liquid directly flows into the material collection frame 610. The liquid will flow into the liquid storage tube 630 along the top of the liquid storage tube 630. When the three liquid storage tubes 630 are filled, the user opens the liquid discharge tube 640 to discharge excess liquid, thereby preventing excess liquid from leaking when the liquid storage tube 630 is taken out.

When the three liquid storage tubes 630 are full, the user opens the drain pipe 640 to drain the excess liquid. This prevents the excess liquid from leaking when the liquid storage tube 630 is taken out. After the liquid storage tube 630 is taken out, it can be sealed with a sealing cover. This facilitates component detection and analysis through the Sudan red detector. When the entire extraction device is used for a long time, the user can directly hold the filter net 730 through the disassembly and cleaning port 320, and the user can directly take out the filter net 730 for replacement and cleaning, and the extracted liquid can be tested and analyzed for components through the Sudan red detector.
