A method for the determination of small molecular compounds in olive oil

Abstract

The invention provides a method for measuring small molecular compounds in olive oil. A real-time direct analysis and flight time mass spectrometry analysis combined technology is adopted, the pretreatment step can be omitted, the collecting time of a sample is shortened, the whole measurement process time is only 20-30 min, and the analysis efficiency can be greatly improved. The mass spectrogramand precision mass number combination is analyzed through software, the components of the small molecular compounds in the olive oil can be accurately measured, the technology does not use any flow phase in the analysis process, and thus solvent pollution can be reduced.

Description

technical field [0001] The invention relates to the technical field of analysis and detection, in particular to a method for measuring small molecule compounds in olive oil. Background technique [0002] Olive oil is directly cold-pressed from fresh olives, without heating and chemical treatment, and retains natural nutrients. Olive oil is considered to be the most suitable fat for human nutrition among the fats found so far. The quality of olive oil ranks first among vegetable oils, so it has the reputation of "Edible Vegetable Oil Queen", which shows that olive oil has an irreplaceable position in vegetable oils. In recent years, the quality of olive oil that people have paid attention to has risen from the previous counterfeit and shoddy to shoddy, mixed with inferior, and the origin of olive oil. Therefore, the traditional method of identifying olive oil is the determination of fatty acids. The method of authenticity has been increasingly challenged. The identificatio...

Problems solved by technology

The sample pretreatment process of these methods basically needs to go through complicated processes such as weighing, extracting, degreasing, purifying, and concentrating, and the time-consuming time for detecting a single sample is 2 to 3 hours. Detection will become a burden on the laboratory, the cost is high, the solvent consumption is large, and it is difficult to complete the detection of a large number of samples in a short time

And when the composition of the olive oil under study is not known, the identification of the compounds becomes a difficult problem and will require a lot of time and effort
