Description
Technical field
The present invention relates to original plasm wine detection fields, and in particular to a kind of pigment array sensing technology Fast Evaluation magma vinosity
The method of amount.
Background technique
The history of China white wine brewing is quite long, can trace back to B.C. 4000-2000, wine-making technology exquisiteness,
Skill is of extensive knowledge and profound scholarship, and product style is unique, and wine body is mellow, long times of aftertaste, enjoys high reputation in the whole world.Therefore, brewed spirit industry
The mainstay industry for becoming China's food service industry has very important status in the national economic development, and becomes country
One of important sources of revenue tax.
Currently, the production technology of liquor industry still relies primarily on traditional means, amount quality picking wine in wine link, the step are steamed
Be mainly characterized by distinguish the ingredient difference of the original plasm wine distilled, judge the quality for distinguishing wine, the at present magma of brewery
Wine goes out wine process and is divided into foreshot, level-one wine, second level wine, liquor tailing four-stage, and wherein foreshot and liquor tailing are not meet subsequent technique
It is required that wine, level-one wine grade highest, second level wine grade is lower, and the price of level-one wine is ten times of second level wine or more.
In most of liquor-making enterprise, the mode manually to savour the wine is generallyd use to carry out quality grading to original plasm wine in real time,
But there is the features such as worker's experience that relies on, be easy error, be big to human body injury in this method.It will lead in this way
The problems such as standard disunity, wine product reduce, heavy economic losses is brought to brewery.To solve the problems, such as this link, large-scale brewery
It has begun and has carried out a large amount of work in terms of original plasm wine, the ingredient being currently known is more than 70 kinds of substances, is led to
Many experiments and experience comparison discovery are crossed, ethyl alcohol and ethyl acetate are most important two kinds of marker substances of original plasm wine quality.But
Current analysis means can not all be applied and carry out on-line checking in production equipment, can not distinguish in real time to the grade of wine.
With the development of instrumental science and calculation method, many new measurement methods are used in concentration of alcohol detection,
Such as near infrared spectroscopy, gas chromatography, Refractive Index Method, liquid chromatography, fluorescence method, Raman spectroscopy.But these instrument
Device equipment costly, and is difficult to realize the on-site test in workshop.
It is by high forces such as covalent bond, ionic bond and oxygen keys that pigment sensor array, which is using pigment molecular and gas,
In conjunction with, have compared with the metal-oxide gas transducers such as traditional electronic nose not vulnerable to vapor, soda acid etc. in environment
The influence of disturbing factor is a kind of ideal tools of original plasm wine Quality Detection.
