Establishment method of smoke sourness index evaluation model based on taste vitality value

Abstract

The invention relates to a cigarette smoke acidity index evaluation model establishment method based on gustation vitality values, and belongs to the technical field of cigarette evaluation. The method comprises the steps as follows: a gas chromatograph-mass spectrometer is utilized to detect the content of organic acids in mainstream cigarette smoke with an N,O- bis(trimethylsilyl)trifluoroacetamide derivatization method; according to a public reported gustation threshold, the gustation vitality values of the organic acids are calculated so as to recognize key acidity substances in the mainstream cigarette smoke; a cigarette smoke acidity index evaluation model is established on the basis of the key acidity substances in the mainstream cigarette smoke; and human sense evaluation of the cigarette smoke acidity intensity is performed by a cigarette sense technician, and statistical software is adopted to perform fitting effect analysis on the cigarette smoke acidity index and a human sense evaluation value. The cigarette smoke acidity index evaluation model and a human sense evaluation method have an ideal fitting effect, the cigarette smoke acidity intensity is objectively evaluated, and the method can be used for development of the cigarette product flavor technology.

Description

Technical field [0001] The invention belongs to the technical field of cigarette evaluation, and specifically relates to a method for establishing a smoke sourness index evaluation model based on a taste vitality value. Background technique [0002] Cigarette product style characteristics are the soul of cigarette products and run through the life cycle of cigarette products. The evaluation of tobacco and tobacco products includes vision, hearing, smell, taste and touch. Visual and auditory evaluations are mostly related to appearance factors, while smell, taste and touch evaluations are closely related to style characteristics. Only through smell, taste and touch Only with common experience can we evaluate the style characteristics of cigarette products comprehensively, objectively and accurately. [0003] Researchers have conducted a lot of exploration and research on the characteristics of smoke aroma style, but the research on the evaluation method of smoke smell style charact...

Problems solved by technology

Currently, many methods for the detection of organic acids in tobacco leaves or smoke have been developed to obtain quantitative data on organic acids, but these methods do not correlate well with quality or style characteristics

[0005] At present, the domestic tobacco industry is still blank in the application of threshold technology to analyze the material basis of quality or style characteristics; the application of electronic tongue bionic technology to distinguish the intensity of sourness, sweetness, bitterness and saltiness of smoke is a new objective quantification Characterization method, but this method has the disadvantage that the detection results are prone to instability due to factors such as artificial saliva and smoke complex samples contaminating the sensor
