Description

A kind of method differentiating true and false import red wine

Technical field

Differentiate a method for true and false import red wine, belong to grape wine authenticate technology field, specifically main chemical compositions authenticate technology field in grape wine.

Background technology

Grape wine is the main large inward of China, according to customs statistics, this year the first three quarters, the accumulative import grape wine 4.3 hundred million liters of China, increases by 46.4% compared with the same period of last year; It is worth 12,100,000,000 yuans, increases by 23%; Import average price is 28.3 yuan often liter, drop 16%. September, of that month import 6,126 ten thousand liters, increased by 78.4% on year-on-year basis, and chain rate increases by 28.6%. European Union is main import sources ground, increases sharply from Chile and Australia's import. The first three quarters, China, from European Union's import grape wine 2.4 hundred million liters, increases by 36.8%, accounts for the 56.8% of China's grape wine import total amount same period. Wherein from France's import 1.5 hundred million liters, increase by 34.1%; From Spain's import 5,694 ten thousand liters, increase by 60%. The same period, from Chile's import 100,000,000 liters, increase by 77.3%, account for 24.4%; From Australia's import 5,094 ten thousand liters, increase by 71.2%, account for 11.9%.

Owing to current grape wine is faked serious, there is phenomenons such as adulterating, mix the spurious with the genuine, so grape wine differentiates to seem especially important. Traditional glucose wine discrimination method mainly contains observes glucose wine wine bottle outward appearance, observation grape wine body, wine plug sign, hears grape wine vinosity and tastes grape wine etc. Traditional discrimination method accuracy is not high, it is necessary to invention one is import red wine discrimination method accurately.

Anthocyanogen is a kind of haematochrome in grape wine, is mainly present in Pericarpium Vitis viniferae, and its skeleton is chromene, is usually combined into glycoside forms with a molecule glucose. Have and remove interior free yl and antioxygenation, it is possible to protection human body red blood cell is not oxidized, because it can reduce the generation of active oxygen (ROS) and methemoglobin in people's red blood cell; Cardiovascular and cerebrovascular diseases etc. can be prevented, can obviously suppress oxidation and the platelet aggregation of low-density lipoprotein, thus contribute to preventing the generation of coronary heart disease and atherosclerosis.

Definition according to international OIV tissue: " grape of 100% or Sucus Vitis viniferae alcopop after spontaneous fermentation, its wine degree can not lower than 8.5%(V/V).

Tannin, it is a kind of materials wherein of two kinds of phenolic compound contained by grape wine, and especially in red wine, content is more. Tannin in grape wine is generally by Semen Vitis viniferae, skin and stalk soaking fermentation, or because the tannin extracting in oak in being stored in oak barrel. Tannin can add in makeup, because skin is had good convergence, sun-proof, whitening, crease-resistant, moisture-keeping function by it, and takes the prevention being of value to cardiovascular disease for a long time. Tannin has antioxygenation, is a kind of natural antiseptic agent, it is possible to effectively avoids grape wine because oxidized and souring, enables the grape wine of standing storage keep optimum regime, so, tannin has decisive effect for the old ability of red wine. The red wine in one bottle of good time, may just can improve after being put into 10 years.

Total reducing sugar amount in grape wine affects one of wine quality and the important indicator distinguishing grape wine kind. The sweet feel of grape wine is mainly from the carbohydrate in wine, sugar in grape wine is the glucose and fructose that are very easily absorbed by the body and utilize, it can be not only the material of the metabolism offer composition of human body and storage power, and can help digest and reconcile lipid and the metabolism with protein in body. Sack: also known as dry wine, in raw material (Sucus Vitis viniferae), sugar changes into alcohol completely, and residual sugar amount is below 0.4%, and imperceptible sweet taste when mouth is commented, only has tart flavour and clear happy tasty and refreshing sensation. Dry wine is the varietal wine of world market major consumers, the kind that the tourism of Ye Shi China is maximum with requirement in foreign trade. Dry wine due to sugar few, so grape variety local flavor embodies the most abundant, by being the main foundation of qualification brewing grape kind quality to judging of dry wine. Dry wine is low due to sugar in addition, thus can not cause fermenting again of yeast, also not easily causes bacterial growth.

Trans-resveratrol is a kind of non-alcoholic content in grape wine, and Pericarpium Vitis viniferae contains a large amount of trans-resveratrols. Trans-resveratrol is phytoalexin, is also exactly natural phytoncide. When plant is subject to environmental stress, fungus and bacterium infection, the antitoxin invasion and attack usually resisting the external world will be produced. As a kind of functional ingredient of grape wine, the effect of trans-resveratrol mainly shows as its anti-oxidation characteristics. There is a kind of saying " France miracle ", general idea says, although Frenchman's frequent edible animal lipid content height food, cholesterol intake is big, Frenchman's mean cholesterol content is also all not less than other country, but Frenchman because of the ratio of Incidence of CHD and mortality ratio be minimum, the 60% of the Jin Shi U.S.. Reason is: Frenchman often drinks grape wine, and the grape wine amount of drinking occupies first place in the world per capita. Why does grape wine have so magical strength? secret be all it-trans-resveratrol. In general, equal trans-resveratrol containing about 1 to 2mg gram in the red wine of every bottle of 750ml, but existing so magical effect.

Summary of the invention

In order to solve Problems existing in the qualification of import red wine, it is an object of the invention to the content by measuring anthocyanogen, alcoholic strength, tannin, total reducing sugar and trans-resveratrol in import red wine is the true and false of judgement red wine.
