The conventional liquid food detection sampling device has a plurality of problems in actual operation, particularly the problem that the sample is difficult to effectively avoid sedimentation, which has great negative influence on the accuracy of the detection result. When components in liquid foods precipitate, the non-uniformity of the samples is increased remarkably, for example, for liquid foods rich in protein, fat or other nutritional components, the components may gradually sink and accumulate at the bottom of a container after standing for a long time, and at this time, if a traditional sampling device is directly used for sampling, the sampled samples may be mostly precipitated components or the upper layer is thinner and lacks representative liquid, which inevitably leads to serious deviation of detection results, for example, in the case of milk detection, if sampling is uneven after precipitation of nutritional components such as fat, the nutritional value of milk may be erroneously estimated, so that consumers are misled in selecting products, and in the case of fruit juice detection, if pulp precipitation leads to sampling deviation, the detection results cannot truly reflect the purity and quality of fruit juice, and the benefit of consumers is impaired. The detection error caused by precipitation can also cause a series of serious consequences that in a production link, an inaccurate detection result can lead enterprises to fail to find product quality problems in time, so that unqualified products flow into markets, the reputation of the enterprises is damaged, the trust crisis of consumers is caused, the incorrect detection data can interfere with decisions of regulatory departments at a monitoring level, accurate assessment of food safety conditions is influenced, and monitoring measures cannot be effectively adopted in time, so that potential risks are brought to public food safety, and therefore, the anti-precipitation sampling device for liquid food detection is provided to improve the problems.
