Portable illegal cooking oil detector

Abstract

A portable illegal cooking oil detector belongs to the technical field of detection, and especially relates to a portable illegal cooking oil detector for detecting whether foodstuff contains illegal cooling oil. The portable illegal cooking oil detector is capable of performing rapid qualitative detection on illegal cooking oil. The portable illegal cooking oil detector comprises a shell on which a display screen observation window, a button and a probe are arranged, the shell is inside provided with a single-chip microcomputer and a display screen, and the display interface of the display screen is corresponding to the display screen observation window; the input terminal of the display screen is connected with the output terminal of the single-chip microcomputer, the output terminals of the button and the probe are respectively connected with the input terminal of the single-chip microcomputer; and the single-chip microcomputer is connected with a power source.

Description

Technical field [0001] The invention belongs to the technical field of detection, and particularly relates to a portable waste oil detector for detecting whether food contains waste oil. Background technique [0002] In response to the problem of waste oil, on March 18, 2010, the Office of the State Food and Drug Administration issued the "Urgent Notice on Preventing Waste Oil from Flowing into Catering Services" (SFDA (2010) No. 25). Ditch oil usually refers to the edible oil discarded by the catering department, which is generally collected from the trenches near hotels and hotels. After refining and processing, the color and nature of the toxic and harmful oils have changed. Waste oil is mostly mixed with domestic garbage, feces, molds and parasites. Therefore, waste oil will gradually undergo a series of changes such as hydrolysis, oxidation, condensation, polymerization, increased acidity, and darker color, resulting in free fatty acid and fatty acid dimerization. Polymers ...

AI Technical Summary

Problems solved by technology

Since polycyclic aromatic hydrocarbons need to be produced in large quantities in a continuous high temperature environment, the error rate of this detection index is relatively large, and the detection equipment is precise and expensive, so it is difficult to carry out portable detection and application promotion of waste oil through this index

In addition, the various components of the oil sample are diffused and separated on the silica gel plate under the action of the developing agent, and different spots can be observed on the silica gel plate after being developed by the chromogenic agent, so thin-layer chromatography can be used for detection, but thin-layer chromatography The method requires high-pressure physical and chemical conditions, and cannot realize the portable detection of waste oil
