The invention provides an apparatus for detecting quality of edible oil on the basis of cholesterol content. The apparatus comprises a shell, wherein the outer surface of the shell is provided with adisplay screen and a control key, the interior of the shell is a cavity structure, a constant potential circuit, a current detection circuit, a first A / D converter, a voltage amplification circuit, asecond A / D converter, a microprocessor and a battery, the lower end of the shell is provided with a probe connecting rod, and the bottom of the probe connecting rod is provided with a cholesterol sensor. By designing the apparatus for detecting the cholesterol, the miniaturization and integration can be realized; and the apparatus is suitable for the on-site detection, the complex sample pretreatment process can be avoided, the cholesterol sensor can be replaced for different samples, whether the edible oil is illegal cooking oil or is mixed with the illegal cooking oil can be rapidly determined, and the apparatus has the advantages of low cost, long service life, good repeatability and high specificity identification capacity.
Description
technical field [0001] The invention relates to the field of edible oil safety, in particular to a device for detecting the quality of edible oil based on cholesterol content. Background technique [0002] my country is the country with the largest consumption of vegetable oil in the world, and a large amount of waste oil is produced every year. Driven by profit, some unscrupulous traders refine waste edible oil and sell it again, or add waste oil to edible oil for sale after refining. Waste edible oil, commonly known as waste oil and swill oil, is generally mixed with a large amount of toxic and harmful substances, such as aflatoxin, benzopyrene, dioxin, and heavy metal ions. Since gutter oil is a mixture of various animal and vegetable oils, animal and plant tissues contain sterols, and the characteristic sterol of animal oils is cholesterol, while vegetable oils generally do not contain or contain a very small amount of cholesterol. By measuring the amount of cholesterol ...
