Method for rapidly evaluating ginseng-adulterated American ginseng based on mouth feel information

Abstract

The invention discloses a method for rapidly evaluating ginseng-adulterated American ginseng based on mouth feel information. According to the method disclosed by the invention, an electronic tongue system based on a lipid bilayer sensitive membrane taste sense sensor is used for detecting taste sense information of the ginseng-adulterated American ginseng with different adulteration ratios at room temperature; a response value and a taste sense value of the sensor are taken as original information respectively and two types of mode identification methods are used for carrying out qualitative identification on the American ginseng with the different adulteration ratios; a linear partial least squares regression model between a typical taste sense characteristic and the adulteration ratio is established according to a change law of typical taste sense information; a bitter taste and astringent model is taken as an adulteration predication model which is used for rapidly evaluating the ginseng-adulterated American ginseng. According to the method disclosed by the invention, the American ginseng with different adulteration ratios can be evaluated to provide objective, accurate and quantized mouth feel information; indexes are simple and easy to understand; the operation is simple, and the evaluation is rapid and accurate; the method can realize the rapid qualitative and quantitative evaluation of the American ginseng with different adulteration ratios by taking the taste sense information as the indexes.

Description

technical field [0001] The invention relates to a method for detecting ginseng adulterated American ginseng, in particular to a method for rapidly detecting ginseng adulterated American ginseng based on taste information. technical background [0002] Both American ginseng and ginseng have important health care and anti-cancer effects, but in terms of certain medicinal effects, American ginseng is superior to ginseng, so there is a large price difference between the two in the market, and the phenomenon of adulterating ginseng slices into American ginseng slices is common. . At present, the identification methods of American ginseng and ginseng at home and abroad are mainly the content identification of specific saponin active ingredients and sensory evaluation (aroma and taste). The former has become an important standard for detecting different types of ginseng and has been included in the national standard. The latter is more common in the market . However, the above me...

Problems solved by technology

However, these methods cannot give and be similar to sensory evaluation index information, such as mouthfeel information, and do not conduct qualitative and quantitative analysis of ginseng mouthfeel components, and the detection time and data processing time are long, the results are cumbersome, and fail to provide a fast and accurate method. , a simple and easy-to-accept evaluation method or index
