[0002] With the attention of people to health and nutrition, functional nutrients are more and more widely used in food, and nutrient extraction methods include solvent extraction, hot water extraction and ultrasonic extraction, etc. When solvent extraction is used, oysters are chopped or shredded to remove impurities, then according to the properties of the target nutrient, an appropriate extraction solvent is selected, such as water, ethanol or methanol, the chopped oyster meat is mixed with the solvent at a ratio of 1:5 or 1:10 and soaked for a certain period of time, usually 24 hours or several days, then a filter or cloth is used to separate the solid and liquid, collect the filtrate, and then transfer the extraction liquid to a sealed container, and then use the inspection equipment gas chromatograph, select a suitable chromatographic column (such as HP-5 or DB-5), and set the temperature program: initial temperature 60℃, keep for 2 minutes, then increase the temperature to 250℃ at a rate of 10℃ / min, keep for 3 minutes. Hydrogen or helium is used as the carrier gas, the flow rate is set to 1mL / min, and the detector temperature is 250℃. The chromatogram is analyzed by gas chromatography software to identify the compounds corresponding to each peak, and the peak area is quantitatively analyzed according to the standard sample. Finally, through this process, not only can the quality of functional nutrients in seafood such as oysters be evaluated, but also the name and content of the extracted nutrients can be ensured through the inspection equipment, providing strong support for quality control and nutrition analysis of seafood. This combined extraction and inspection process can more effectively meet the growing demand for healthy food in the market.
[0003] Traditional functional nutrient extraction requires operators to manually cut the raw materials to remove impurities and increase the surface area, and also needs to manually add solution and add it to the raw materials, etc. This increases the operation steps, and after extraction is completed, the mixture needs to be manually transferred to a solid-liquid separation container, and finally poured into a test tube. Each step requires manual intervention, which makes the whole process complex and inefficient. Independent operation at each link not only increases the time cost, but also may cause poor information transmission and increase the possibility of errors, affecting the final extraction effect.

[0013] The functional nutrient inspection device comprises the following steps:
[0014] S1, sample injection: the sample is injected into the injection port of the gas chromatograph, usually in liquid or gas form. The injection port has a heating function to rapidly vaporize the sample to ensure that the sample entering the chromatographic column is in a gaseous state. In the analysis of solvent-extracted nutrients, the extracted nutrient filtrate or solution sample is injected for subsequent analysis.
[0015] S2, carrier gas flow and transmission: high-purity hydrogen or helium is used as the carrier gas (flow rate is 1 mL / min) to bring the gaseous sample from the injection port into the chromatographic column.

[0036] When the extraction mechanism is in use, first, the dried oyster meat is placed in the mincing cylinder 6, and then the threaded rod 8 is rotated, which drives the mincing cover 9 and the mincing blade 11 to move downward and enter the mincing cylinder 6. Then, the power is turned on, and the servo motor 10 is started, which drives the mincing blade 11 to rotate. When the mincing blade 11 rotates, it will mince the oyster meat inside the mincing cylinder 6. After mincing, the valve 27 is opened, and the minced oyster meat will fall into the glass mixing vessel 13. Then, the valve 27 at the bottom of the solution storage tank 14 is opened, and the solution in the solution storage tank 14 will flow into the glass mixing vessel 13 through the infusion tube 15. The mixing ratio can be 1:5 or 1:10.

After extraction is completed, the gas chromatograph body 2 drives the feeding turntable 3 to rotate, which moves the test tube containing the solution to the bottom of the gas chromatograph body 2 for testing. After the oyster meat is minced by the servo motor 10 in the extraction mechanism, it does not need to be transferred to other containers. It only needs to open the valve 27, and the minced oyster meat will directly fall into the glass mixing vessel 13. Then, the valve 27 at the bottom of the solution storage tank 14 is opened, and the solution will flow into the glass mixing vessel 13. After adding, the valve 27 is closed, and the oyster meat is soaked for a certain period of time. At the same time, the glass mixing vessel 13 can be heated to enhance the penetration and extraction effect of the solvent on the raw material. After soaking is completed, the valve 27 at the second connecting tube 18 is opened, and the oyster meat and the solution will directly flow into the filter cloth 23 for filtration, without the need to transfer the mixture to other vessels.The filtered solution directly flows into the test tube through the downcomer 20 and is sent into the gas chromatograph body 2 for inspection, which solves the problem that manual intervention is required at each step, so that the whole process becomes complex and inefficient, the independent operation of each link not only increases the time cost, but also increases the possibility of errors, affects the final extraction effect, and further realizes rapid extraction of the whole process, reduces manual intervention, simplifies the operation process, optimization of each link not only saves time, but also reduces the risk of errors, thereby ensuring the stability of the extraction effect.
