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. ...
