Embodiment Construction

[0018] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be pointed out that in the present invention, specific vegetable oil refers to olive oil or sesame oil.

[0019] In the present invention, according to the principle that a specific vegetable oil will produce fluorescence under the excitation of excitation light of a specific wavelength, the specific vegetable oil is excited with light of a specific wavelength, and the fluorescence signal emitted by the specific vegetable oil under the excitation of the above-mentioned specific wavelength of light is collected. . Afterwards, a digital signal representing the intensity of the above-mentioned fluorescent signal is obtained. For example, through a series of transformations, the peak area of ​​the aforementioned fluorescence s...

Description

technical field [0001] The invention belongs to the technical field of food detection, and in particular relates to a specific vegetable oil safety screening detection method, equipment and system. Background technique [0002] Vegetable oil is the most common condiment used by residents, and it is also a medium for heating raw materials, which has the functions of seasoning and heat transfer. As one of the important nutrients needed by the human body, vegetable oil is an indispensable necessity in our daily life. However, in recent years, vegetable oil quality problems have been threatening people's health, and even reports of waste oil returning to the dining table are common: some unscrupulous vendors return the reused vegetable oil to the dining table after simple treatment, and the repeatedly used vegetable oil is harmful to the human body. Health poses a major threat. [0003] At present, the methods for identifying inferior oil are mainly chemical detection method, ...
