Embodiment 1

[0044] A method for characterizing the taste of oral type smokeless tobacco products based on an electronic tongue, comprising the following steps:

[0045] Step (1), sample extraction: put 1 g of the oral smokeless tobacco product into a container, add 50 mL of solvent, and perform ultrasonic extraction to obtain a sample extract;

[0046] Described solvent is 10mmol / L potassium chloride solution;

[0047] Step (2), sample purification: the sample extract is purified by filtering to obtain a sample purification solution;

[0048] Step (3), detection and analysis: use the solvent for preparing the sample extract as the control solution, then use the electronic tongue to detect the sample purification solution and the control solution together, and then subtract the respective taste value data obtained from the sample purification solution from the corresponding control solution. The final taste data of the purified liquid of the sample is obtained.

[0049] The filtration is...

Embodiment 2

[0051] A method for characterizing the taste of oral type smokeless tobacco products based on an electronic tongue, comprising the following steps:

[0052] Step (1), sample extraction: put 10g of oral smokeless tobacco products into a container, add 150mL of solvent, and perform ultrasonic extraction for 60min to obtain a sample extract;

[0053] Described solvent is 50mmol / L potassium chloride solution;

[0054]Step (2), sample purification: the sample extract is purified by filtering to obtain a sample purification solution;

[0055] Step (3), detection and analysis: use the solvent for preparing the sample extract as the control solution, then use the electronic tongue to detect the sample purification solution and the control solution together, and then subtract the respective taste value data obtained from the sample purification solution from the corresponding control solution. The final taste data of the purified liquid of the sample is obtained.

Embodiment 3

[0062] A method for characterizing the taste of oral type smokeless tobacco products based on an electronic tongue, comprising the following steps:

[0063] Step (1), sample extraction: put 5g of oral smokeless tobacco products into a container, add 140mL of solvent, and perform ultrasonic extraction for 30min to obtain a sample extract;

[0064] Described solvent is ultrapure water;

[0065] Step (2), sample purification: the sample extract is purified by natural clarification, centrifugation or filtration to obtain a sample purification solution;

[0066] Step (3), detection and analysis: use the solvent for preparing the sample extract as the control solution, then use the electronic tongue to detect the sample purification solution and the control solution together, and then subtract the respective taste value data obtained from the sample purification solution from the corresponding control solution. The final taste data of the purified liquid of the sample is obtained. ...

Abstract

The invention relates to a method for characterizing taste of mouth-used type smokeless tobacco products based on an electronic tongue, and belongs to the technical field of analysis of a taste valuein smokeless tobaccos. The method for characterizing the taste of the mouth-used type smokeless tobacco products based on the electronic tongue comprises the steps that the mouth-used type smokeless tobacco products are placed into a container, a solvent is added, ultrasonic extraction is carried out, and an obtained sample extraction solution is purified by adopting a mode of natural clarification and centrifugation or filtration; and the solvent for preparing the sample extraction solution is used as a contrast solution, then the contrast solution and a sample purification solution are detected by adopting the electronic tongue, and final taste data of the sample purification solution is obtained by subtracting corresponding taste value data of the contrast solution from obtained each taste value data of the sample extraction solution; and finally, qualitative and quantitative analysis is carried out on the taste of the tobacco products by combining PCA principal component analysis.The method for characterizing the taste of the mouth-used type smokeless tobacco products based on the electronic tongue can well avoid subjective factor influence and difference property characterization brought by virtue of traditional artificial sensing food-tasting, is more objective and efficient, has good repeatability, high sensitivity and simple operation, and is easy to popularize and apply.

Description

technical field [0001] The invention belongs to the technical field of analysis of taste values ​​in smokeless tobacco, and in particular relates to a taste characterizing method for oral type smokeless tobacco products based on an electronic tongue. Background technique [0002] Smokeless tobacco products (STPs) provide nicotine to the human body by mouth, sucking, chewing, etc. The products include various forms such as snus, snuff and chewing tobacco. Among them, the main consumers of oral smokeless tobacco products are pouched cigarettes, gum-based chewing tobacco and cigarettes. Cigarettes in the mouth are made of tobacco powder of a certain particle size mixed with an appropriate amount of aroma substances, flavoring agents, water, humectants and acid-base regulators through heat treatment. They are packaged in non-woven bags and placed on the lips consumption between. Gum-based chewing tobacco, also known as chewing tobacco, gum-based tobacco, and tobacco chewing gu...
