Problems solved by technology

[0004] Unfortunately, at this stage, there is no way to check whether there are drugs in food
Although the invention patent "A Method for Detecting Drug Residues in the Human Body" declared by Zhan Huaqiang on November 05, 2009 can quickly detect whether the human body contains drugs, but this method can only judge whether the person being tested is Smoking drugs, or whether the food containing drugs is used, but it is not possible to directly detect whether the food contains drugs

specific Embodiment 1

[0029] This example is an example of detecting whether marijuana is contained in California beef noodle soup.

[0030] In order to attract customers, some noodle restaurants add drugs and marijuana to the noodles to make them have endless aftertaste after eating the noodles. Since the seasoning of the noodles is added to the soup, only the noodle soup needs to be tested. .

[0031] In this embodiment, the method for detecting whether marijuana is added to food, the flow chart is as follows figure 1 shown. The method includes the following steps:

[0032] Step a, pre-treatment of food to be tested

[0033] At 20°C, mix the noodle soup and water at a mass ratio of 1:1, stir, filter, and take 50ml of the filtrate as the solution to be tested;

[0034] Step b, liquid chromatography separation

[0035] Capillary pump chromatography conditions: mobile phase A is an aqueous solution with a volume concentration of 1% formic acid, mobile phase B is an acetonitrile solution with a ...

specific Embodiment 2

[0048] This embodiment is an embodiment of detecting whether marijuana is contained in the noodle soup of a certain noodle shop.

[0049] In order to attract customers, some noodle restaurants add drugs and marijuana to the noodles to make them have endless aftertaste after eating the noodles. Since the seasoning of the noodles is added to the soup, only the noodle soup needs to be tested. .

[0050] In this embodiment, the method for detecting whether marijuana is added to food, the flow chart is as follows figure 1 shown. The method includes the following steps:

[0051] Step a, pre-treatment of food to be tested

[0052] At 20°C, mix the noodle soup and water at a mass ratio of 1:1, stir, filter, and take 50ml of the filtrate as the solution to be tested;

[0053] Step b, liquid chromatography separation

[0054] Capillary pump chromatography conditions: mobile phase A is an aqueous solution with a volume concentration of 1% formic acid, mobile phase B is an acetonitri...

specific Embodiment 3

[0067] This embodiment is an embodiment of detecting whether marijuana is contained in the cake.

[0068] In this embodiment, the method for detecting whether marijuana is added to food, the flow chart is as follows figure 1 shown. The method includes the following steps:

[0069] Step a, pre-treatment of food to be tested

[0070] At 20°C, mix the cake and acetonitrile at a mass ratio of 1:10, and the acetonitrile does not cover the upper surface of the cake. After 30 minutes, filter the acetonitrile solution, and take 50ml of the filtrate as the solution to be tested;

[0071] Step b, liquid chromatography separation

[0072] Capillary pump chromatography conditions: mobile phase A is an aqueous solution with a volume concentration of 1% formic acid, mobile phase B is an acetonitrile solution with a volume concentration of 1% formic acid, the flow rate is 1 μl / min gradient elution, and the proportion of mobile phase A is 80% , the proportion of mobile phase B is 20%;

Abstract

The invention belongs to the field of food safety, and particularly relates to a method for detecting content of hemp in food. The method includes pretreating to-be-detected food, performing liquid chromatographic separation, and utilizing mass spectrometry to detect the content of the hemp. By the method, whether the hemp is contained in the food or not can be detected; the method can be used by government law-enforcing departments and food safety management departments.

Description

technical field [0001] A method for detecting whether marijuana is added in food belongs to the field of food safety, and specifically relates to a method for detecting whether addictive additives are contained in food. Background technique [0002] Drugs are highly addictive drugs, and the state has clear restrictions on them. However, the drug trade is still going on. According to statistics, the global drug trade volume ranks second in the world after arms. Drugs play a vital role in medical and pharmaceutical processes, but they have also become hidden dangers among the people. [0003] In addition to drug trafficking, private quack doctors grow their own drugs, and the catering industry mixes drugs in food in order to attract customers. We can avoid drug trafficking and quack doctors, but we are unknowingly addicted to the catering industry. Since taking drugs for a long time or using food containing drugs is not only addictive, but also affects health, it is necess...
