Problems solved by technology

The source of hogwash oil is complex, the above method can only be used for the detection of hogwash oil from a specific source, and lacks wide applicability
In addition, there are disadvantages such as cumbersome operation process, long time-consuming, high cost, etc., and rapid on-site detection cannot be realized

Embodiment Construction

[0034] The following examples are further detailed descriptions of the present invention.

[0035] In this specific example, 300 edible vegetable oil samples from different sources with different contents of cholesterol, triacylglycerol polymers, benzo(a)pyrene and heavy metals and 3 edible vegetable oil samples from unknown sources are taken as examples. The 3 edible vegetable oil samples of unknown origin were designated as sample A, sample B and sample C respectively. 300 edible vegetable oil samples were used to establish detection models for cholesterol, triacylglycerol polymers, benzo(a)pyrene and heavy metals, and 3 edible vegetable oil samples from unknown sources were used as samples to be tested to determine whether they were hogwash oil.

[0036] Such as figure 1 As shown, in the method for rapid detection of hogwash oil based on multi-source information fusion in this embodiment, sample A is loaded into the quartz vessel 8 on the stage 9 as the sample 10, and the ...

Abstract

The invention discloses a method and a device for quickly detecting hogwash oil based on multi-source information fusion. The method comprises the following steps: sequentially collecting a near-infrared spectrum, a three-dimensional synchronous fluorescence spectrum and a laser-induced breakdown spectrum of a sample; detecting the content of cholesterol and the content of triacylglycerol polymer in the sample according to information of the near-infrared spectrum, detecting the content of benzopyrene in the sample according to information of the three-dimensional synchronous fluorescence spectrum and detecting the content of heavy metal in the sample according to information of the laser-induced breakdown spectrum; and respectively comparing the contents of cholesterol, triacylglycerol polymer, benzopyrene and heavy metal of the sample with determined thresholds, and determining the sample as the hogwash oil when one content is greater than the determined threshold. The method can be used for quickly distinguishing and detecting the hogwash oil from different sources in the field.

Description

technical field [0001] The invention relates to the technical field of agricultural product / food safety detection, in particular to a rapid detection method and device for hogwash oil based on multi-source information fusion. Background technique [0002] Swill oil, also known as swill oil, is the greasy floating matter in the sewer, or the leftovers in restaurants and hotels, and the upper oil slick after collecting leftovers, which is simply processed and extracted. The sanitation environment of hogwash oil recovery, processing and refining is poor, resulting in the hogwash oil containing a variety of toxic and harmful components, including aflatoxins, heavy metals, bacteria, etc. seriously exceeding the standard. In order to make huge profits, unscrupulous businessmen mix hog oil into qualified edible vegetable oil or directly sell it as qualified edible vegetable oil, which endangers people's health. [0003] At present, the existing detection methods for hogwash oil in...
