Problems solved by technology

The existing detection and discovery of waste oil technology is still blank
In September 2011, the Ministry of Health of the People's Republic of China publicly solicited the detection and discovery methods of waste oil in the whole country. According to the release of Beijing Food Safety Monitoring Center in October 2011, the key to the detection of waste oil is the four core indicators, namely polycyclic aromatic hydrocarbons, cholesterol, and electrical conductivity. Tested with specific genes, none of the five methods solicited publicly before September 2011 could distinguish waste oil
After expert demonstration, it is found that these methods are not very specific, and cannot be used as an effective means of judging and identifying waste oil.

Embodiment 1

[0010] A method of labeling and discovering waste oil. In the used kitchen waste oil, it can be regulated by the government or voluntarily by the merchant. All used kitchen waste oil must be added with a tracer before leaving the restaurant. , such as isotope tracers, the tracer dose is very small to meet the detection needs, and the price is not expensive. Because it is "adding" things to the kitchen waste oil, and the amount of addition is very small, this key link is relatively easy to achieve. As long as a small amount of tracer is added to a part of kitchen waste oil, due to the characteristics of the tracer, even if it is diluted, high-temperature treatment, adsorption deodorization, bleaching and decolorization, alkali deacidification and other special treatments after recovery, it still remains It is difficult to remove all tracer marks. When recyclers process kitchen waste oil, because they must mix the recovered oil from various places and use utensils to hold the r...

Embodiment 2

[0012] A method of labeling and discovering waste oil. In the used kitchen waste oil, it can be regulated by the government or voluntarily carried out by the merchants. Every used kitchen waste oil must be added with a tracer, such as a fluorescent indicator. tracer. Because it is "adding" things to the waste oil, and the amount of addition is very small, it is not very difficult to realize this key link. As long as a small amount of tracer is added to some kitchen waste oil, due to the characteristics of the tracer, even if it is recycled after high-temperature treatment, adsorption deodorization, bleaching and decolorization, alkali deacidification and other special treatments, it is still difficult Remove all trace marks. If unscrupulous users process waste kitchen oil, because they must mix the oil recovered from various places and use containers to hold the recovered oil, their containers and utensils will also be very easy to be contaminated with markers, so that they w...

Abstract

The invention discloses a method for simply and clearly detecting and finding recovered oil processed from kitchen waste oil through an instrument by adding a tracer in the used kitchen waste oil for clearly marking the kitchen waste oil. Therefore, the kitchen waste oil after recovery can still be simply and clearly detected even through the treatment, such as dilution, high temperature, deodorization, bleaching, deacidification and the like, and a way that people re-eat the kitchen waste oil is further cut off. The method disclosed by the invention has the advantages of high sensitivity in identification, simple identification method, accurate identification result, low using cost and no impacts on reasonable re-utilization of the kitchen waste oil, and is easy to popularize and use.

Description

technical field [0001] The invention relates to a method for marking and finding waste oil. Background technique [0002] Waste kitchen oil recovered from kitchens, sewers, etc., is processed and reused by lawless people for human consumption, which is called gutter oil. Existing detection, discovery waste oil technology is still blank. In September 2011, the Ministry of Health of the People’s Republic of China publicly solicited the detection and discovery methods of waste oil in the whole country. According to the release of Beijing Food Safety Monitoring Center in October 2011, the key to the detection of waste oil is the four core indicators, namely polycyclic aromatic hydrocarbons, cholesterol, and electrical conductivity. The five methods collected publicly before September 2011 were unable to distinguish waste oil. After expert demonstration, it is found that these methods are not very specific, and cannot be used as an effective means of judging and identifying was...
