Hereinafter, the authenticity determination method of the present invention based on the above configuration will be described in order.

4 is a flowchart illustrating a method of determining the authenticity of sesame oil using the sesame oil authenticity determination device according to the present invention.

First, a step of obtaining a sample of edible oil and fat for which authenticity is to be determined is proceeded (302).

Next, using a paper filter to filter the powder generated while making impurities or oil contained in the edible oil and fat (304). In order to filter out impurities or powder in edible oil, edible oil is filtered through a paper filter (grade no. 1) because the scattering and permeation disturbances caused by impurities or powder cannot be used for accurate analysis. to be. On the other hand, the edible oil to be measured is placed in a test tube having an inner diameter of 8 mm and a length of 75 mm, and the samples are evenly mixed while inverting the number 10 so that bubbles are not formed. The reason why bubbles should be prevented is that when bubbles are generated, scattering of light affects the transmitted light so that accurate analysis cannot be made.

Next, after injecting the edible oil into the glass test tube 30, and put it in the measuring unit (306).

Subsequently, when light (near infrared) is irradiated from the light source 14, the irradiated light is transmitted to the edible oil and fat contained in the glass test tube 30 through the first optical fiber 15, and the light transmitted through the glass test tube is the second optical fiber. And transmitted to spectrophotometer 17 via (16) (308). That is, the light source is driven to irradiate the edible oil contained in the glass test tube, and the light transmitted through the edible oil is transmitted to the spectrophotometer 17 through the second optical fiber 16.

The spectrophotometer 17 generates an electrical spectral signal by spectroscopically processing the light transmitted through the edible oil and fat (310).

Subsequently, when the electrical spectrum signal is transmitted to the authenticity determination unit 20, the authenticity determination unit uses a program capable of calculating the authenticity of sesame oil of edible fat or oil, or the content of sesame oil and heterogeneous oil (30). Calculate the authenticity of the sesame oil contained in or the content of the fake sesame oil (312).

Finally, as shown in FIG. 3, the results of the authenticity discrimination unit are visually output to a monitor or a printer, and a measurer can quickly and easily check the authenticity of the edible oil and the content of sesame oil and heterogeneous oil within 1 second. 314.

Hereinafter, the authenticity prediction model program or the content prediction model program used in the authenticity determination unit 20 will be described.

First of all, prepare real sesame oil and heterogeneous oil such as corn oil, soybean oil and perilla oil. Prepare five or more standard samples of real sesame oil and corn oil (or soybean oil or perilla oil) at different weight ratios. For example, prepare a standard sample mixed with 0% by weight, 10% by weight, 20% by weight, 30% by weight, 40% by weight, and 50% by weight of corn oil (or soybean oil or perilla oil) in sesame oil. After each standard sample is irradiated with near-infrared rays, each spectrum is obtained, and the obtained spectrum is analyzed to generate an authenticity prediction model program or a content prediction model program. In other words, the authenticity prediction model program or the content prediction model program is configured to use statistically calculated values by analyzing the spectra of a plurality of standard samples in which true sesame oil and heterogeneous oil are mixed at various mixing ratios.

Meanwhile, two or more kinds of verification samples having the same mixing ratio as the standard sample are prepared, for example, 40 wt% and 50 wt%, and the authenticity is determined using the authenticity prediction model program obtained above. The content of sesame oil and dissimilar oil in the prepared edible oil and fat was measured using the content prediction model program, and then the value of sesame oil and dissimilar oil of the test sample predicted by the content prediction model program (hereinafter, referred to as 'prediction value') Comparing with the actual content value (hereinafter referred to as 'actual value') of each test sample, completes the content prediction model program that the difference between the predicted value and the actual value is within ± 10% by weight.

Here, ± 10% by weight, which is set as the limit of the error between the predicted value and the actual value of the verification sample by the content prediction model program, is a value obtained through characteristic differences, errors in analysis, and many trials and errors that are the same natural products. .

On the other hand, at least two types of verification samples used for verifying the authenticity prediction model program or the content prediction model program obtained by using the standard sample may be improved in reliability. In addition, the verification sample may be a part of the standard sample after sufficient preparation of the standard sample as a verification sample, but it is preferable to make the verification sample separately in the same way as the standard sample.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Therefore, the technical scope of the present invention should not be limited to the contents described in the detailed description of the specification, but should be defined by the claims.
