Embodiment

[0030] A method for detecting the content of heavy metal elements in soybean products uses a sampling device for sampling.

[0031] A sampling device, substantially as attached figure 1 , attached figure 2 And attached image 3 As shown, it includes a frame and a crushing bucket 1 fixed on the frame, and a motor 5 is fixed on the frame above the crushing bucket 1 .

[0032] A glass plate is fixed on the upper part of the crushing barrel 1, and a crushing shaft 4 fixedly connected to the output shaft 6 of the motor 5 is arranged above the glass plate, and two layers of grinding wheels fixed on the crushing shaft 4 are arranged along the vertical direction of the crushing shaft 4. A stick 3, the surface of the grinding stick 3 is bonded with a toughened glass layer. The bottom of the glass plate is provided with two feeding ports 19, the left side is the matching feeding port, and the right side is the detecting feeding port. The left side of the control feed port and the r...

Abstract

The invention relates to the technical field of heavy metal detection, and discloses a method for detecting content of heavy metal elements in a bean product. The detection method comprises the following steps of: step 1, selecting a dryer bean product, and drying the bean product; step 2, placing the dried bean product in the step 1 in a crushing barrel, crushing the bean product through a nonmetal grinding roller, quantifying the bean product, and filtering and removing bigger bean product particles so as to sample the bean product; step 3, placing the sample in the step 2 in a beaker, quantitatively adding digestion solution, and closing the beaker; step 4, resting the sample added with the digestion solution for 12h, heating the rested sample, and completely taking out the heated sample; step 5, and placing the taken out sample in a heavy metal detector for detection. According to the method for detecting the content of the heavy metal elements in the bean product, the heavy metalsin the bean product can be detected, and the sample can be detected multiple times so as to improve the detection working efficiency.

Description

technical field [0001] The invention relates to the technical field of heavy metal detection, in particular to a method for detecting the content of heavy metal elements in soybean products. Background technique [0002] Soy products are foods made from processed beans such as soybeans and adzuki beans as the main raw materials. Most soy products are tofu and its re-products made from coagulated soybean milk. [0003] Due to the continuous development of industrialization in human society, in industrialized production, a large number of toxic and harmful heavy metal elements will be discharged into the atmosphere, soil and water with waste. If heavy metals such as lead, mercury, and cadmium in soil and water exceed the standard, these Heavy metals can cause environmental pollution. When soybeans are grown in such an environment, soybeans will also contain these heavy metal elements. Once people eat these soybeans, these heavy metals will accumulate in the human body. When...
