Embodiment Construction

[0024] In the following, the present invention will be further described in conjunction with the embodiments.

[0025] Instruments and reagents

[0026] Cary Eclipse fluorescence spectrometer from Varian Ltd.;

[0027] The 1cm quartz cuvette is the measuring container.

[0028] Sample source

[0029] Twelve samples of edible oil (rice bran oil, blended oil, soybean oil, rapeseed oil) and 4 samples of slop oil were provided by Chuzhou City Technical Supervision and Testing Center.

[0030] A method for rapidly detecting slop oil using synchronous fluorescence spectroscopy, which is characterized in that it comprises the following steps:

[0031] (1) Prepare samples

[0032] Mix edible oil and swill oil in different proportions. The mass percentages of stilt oil are: 90%, 80%, 70%, 60%, 50%, 40%, 30%, 20%, 10% respectively with rice bran oil, The blended oil, soybean oil and rapeseed oil were mixed, stirred and evenly mixed to obtain 72 mixed oil samples.

[0033] (2) Collect spectrum

Abstract

The invention relates to a method for rapidly detecting hogwash oil by synchronous fluorescence spectrum. The method is characterized by comprising the following steps of: preparing a sample; acquiring the synchronous fluorescence spectrum; establishing a model; and judging the unknown sample. Compared with the prior art, the method for rapidly detecting the hogwash oil by the synchronous fluorescence spectrum is based on a support vector machine algorithm, adopts the synchronous fluorescence spectrum technology, and establishes the judgment model judge the hogwash oil without pretreatment of the sample; no other chemical reagents are consumed during testing, the testing time is only 2-3 minutes, and the testing result is accurate and has good repeatability.

Description

Technical field [0001] The invention relates to a method for rapidly detecting sloppy oil, in particular to a synchronous fluorescence spectroscopy technique based on a support vector machine for the detection of sloppy oil. Background technique [0002] Swish oil is a secondary oil obtained through reprocessing and refining. It contains a large amount of saturated and unsaturated aldehydes, ketones, lactones, even acrylamide, polycyclic aromatic hydrocarbons and carcinogenic compounds. These substances have serious damage to the human enzyme system. On the other hand, repeated heating and refining reduce nutrients such as vitamin E and plant sterols. In order to pursue high profits, unscrupulous traders mix edible oil with slop oil, which poses a serious threat to the health of the people. Therefore, it is necessary to strengthen the development of slop oil detection technology to ensure the safety of edible oil. [0003] Domestic scholars have actively explored the detection of...
