Abstract

The invention provides a fast detection method of illegal cooking oil. The method comprises the steps of: testing a standard value of qualified edible oil; heating the qualified edible oil till volatilized gas is generated; detecting the volatilized gas by M gas sensors only used for detecting gas concentrations of different types to obtain M gas concentration standard values of gases of different types; detecting the edible oil to be detected: the same as the above method, detecting the edible oil to be detected to obtain N gas concentration parameters of gases of different types; selection and comparison: selecting N gas concentration standard values corresponding to the N gas concentration standard values of gases of different types from the M gas concentration standard values of gases of different types, and comparing the N gas concentration standard values with the N gas concentration parameters of gases of different types to obtain N groups of comparison results; and judging whether the edible oil to be detected is illegal cooking oil or not. The method provided by the invention has the advantages of scientific process, easy implementation, strong practicality and high detection accuracy.

Description

technical field

[0001] The invention relates to a grease detection method, in particular to a rapid detection method of waste oil. Background technique

[0002] Waste oil is also known as swill oil and swill oil. Its sources mainly include: the oil that is simply processed and extracted from waste oil from catering, or the oil that is reused directly or after adding new oil after frying oil has been used more than the specified number of times, or Oil produced from processing low-quality pork, animal viscera, and animal hides. The heavy metals and toxins in waste oil are seriously over the standard. Long-term intake will cause cell function failure, induce various diseases, and even cause cancer. Unscrupulous speculators use cooking oil mixed with waste oil in food, which is difficult to distinguish from the appearance and sense, causing great harm to society and food safety.

[0003] Recently, commonly used detection methods include high-performance liquid chromatography,...
