Problems solved by technology

[0003] For adulteration in sesame oil, it can be identified according to the color, smell, taste and other appearance characteristics. The sensory test method is simple and easy to implement, and is suitable for the detection of some adulterated oil samples to a certain extent, but it is not sensitive to the sensitivity and practice of inspectors. Experience has certain requirements, so sensory testing can only be used as a preliminary judgment
In addition, some researchers have proposed chemical detection methods such as gas chromatography and chromogenic method according to the special components in the oil sample, which have high accuracy and achieved improved results, but they have relatively high requirements for chemicals and cumbersome experimental operations. The detection speed is not high, and a certain experimental environment is required, so it cannot be widely used in on-site detection

Embodiment 1

[0039] Embodiment 1: as figure 1As shown, an air permeability detection method of perforated tipping paper in the tobacco industry is applied in the adulteration detection of edible oil. First, the absorbance at the characteristic wavelength in the ultraviolet-visible absorption spectrum of the edible oil sample is established through the confidence rule library Confidence rules between edible oil adulteration detection and oil sample attributes, and then constitute the edible oil adulteration detection confidence rule library model; then according to the collected edible oil oil sample UV-visible absorption spectrum data, use particle swarm optimization algorithm to train edible oil adulteration detection confidence rules library model; finally, the trained high-accuracy edible oil adulteration detection confidence rule library model is applied to edible oil adulteration detection.

Embodiment 2

[0040] Embodiment 2: as figure 1 As shown, the application of a perforated tipping paper air permeability detection method in the tobacco industry in the adulteration detection of edible oil, in step Step3, the optimization objective of the confidence rule base model for adulteration detection of edible oil is determined as:

[0041] m i n V max { ξ n ( V ) , n = 1 , 2 , ... , N } - - - ( 1 )

[0042] ξ n ( V ) = 1 T Σ m = ...

Embodiment 3

[0048] Embodiment 3: as figure 1 Shown, the application of the perforated tipping paper air permeability detection method in the tobacco industry in the adulteration detection of edible oil, the specific steps of the adulteration detection of the edible oil are as follows:

[0049] Step1, select N kinds of edible oil samples, determine the characteristic wavelength of its ultraviolet-visible absorption spectrum, use the absorbance at the characteristic wavelength as the input variable of the confidence rule base model of edible oil adulteration detection, and then set the evaluation level for all input variables, And set the corresponding output code for the edible oil sample, that is, the subjective observation value:

[0050] Select the characteristic wavelength λ={λ of the ultraviolet-visible absorption spectrum of edible oil sample i ,i=1,2,…,M}, the absorbance at the characteristic wavelength is the input variable, the reference value A of the evaluation level of the i...

Abstract

The invention relates to application of a detection method for the air permeability of perforated tipping paper in the tobacco industry in adulteration detection of edible oil and belongs to the field of food safety detection. According to the application, firstly, confidence rules between light absorbance at characteristic wavelengths in ultraviolet-visible absorption spectra of edible oil samples and attributes of the oil samples are established through a confidence rule library, and then an edible oil adulteration detection confidence rule library model is formed; then, the edible oil adulteration detection confidence rule library model is trained with a particle swarm optimization according to collected ultraviolet-visible absorption spectrum data of the edible oil samples; finally, the high-accuracy edible oil adulteration detection confidence rule library model obtained through training is applied to adulteration detection of edible oil. According to the application, the relation between the light absorbance at characteristic wavelengths and the attributes of the oil samples is reflected, and the adulteration detection of edible oil can be easily and quickly completed under the assistance of an ultraviolet-visible spectrograph.

Description

technical field [0001] The invention relates to the application of a perforated tipping paper air permeability detection method in the tobacco industry in the adulteration detection of edible oil, belonging to the field of food safety detection. Background technique [0002] People depend on food, and the quality of edible vegetable oil is also related to the national economy and the people's livelihood. Among them, sesame oil is deeply loved by people for its unique fragrance and nutritional and health functions. But it is its high market price and popularity that have caused the adulteration of sesame oil. In order to make huge profits, some unscrupulous traders mix animal oil, rapeseed oil, palm oil, etc. in sesame oil. Its adulteration has seriously affected the hygienic quality and nutritional content. Therefore, from the perspective of consumers' health and interests, it is very important to test and classify sesame oil. [0003] For adulteration in sesame oil, it ca...
