Testing reagent for illegal cooking oil

Abstract

The invention discloses a testing reagent for illegal cooking oil and an application of the testing reagent. The testing reagent is characterized in that the reagent is a testing reagent for a polar landmark, and comprises 1-10% by volume of trichloroacetic acid, 0.1-1% by volume of thiobarbituric acid, and the balance of distilled water; and the components are kept in dark place after being mixed and prepared. The invention also discloses an application of the testing reagent for illegal cooking oil. The reagent is acid value and moisture testing reagent and contains 0.01-1% of bromophenol blue; and an alkaline organic solvent is prepared by dissolving the testing reagent into methanol or ethanol and then adding potassium hydroxide, sodium hydroxide, or other alkaline substances. The testing reagent for the polar landmark and the acid value and the moisture testing reagent are utilized to detect the same oil sample to be tested, the sample is judged to be a positive sample if any testing result is positive, and the sample is judged to be a negative sample if all testing results are negative. According to the invention, the accuracy rate is greatly improved and is extensive in the market prospect.

Description

[0001] technical field [0002] The invention discloses the use of a waste oil detection reagent and belongs to the technical field of food safety detection. Background technique [0003] Waste oil includes swill oil, corpse oil, waste oil, and mixed oil. The raw materials are mixed with a lot of sewage, garbage, detergent, carrion, etc., and contain heavy metals, arsenic, mold, aflatoxin, benzopyrene, etc. The ingredients can poison the brain, intestines and stomach, liver, kidneys and other organs, causing dizziness, insomnia, fatigue, indigestion, headache, liver discomfort, stomach cancer, intestinal cancer, kidney cancer, and lesions in breast, ovary, small intestine and other parts. Waste oil lacks vitamin E and unsaturated fatty acids that the human body needs to ingest from qualified oils. Instead, it increases a large amount of trans fatty acids and saturated fatty acids, which can easily cause obesity, fatty liver, hyperlipidemia, high blood pressure, cholecystitis...
