Problems solved by technology

[0002] In 2006, my country's new national standard GB 15037 "Wine" clearly stipulates the concept of origin, variety and year of wine, but my country still lacks effective identification techniques and methods for origin wine
[0006] Among the above studies, based on 51 kinds of inorganic elements, the research on the identification of Chinese origin wines using multivariate data processing model technology has not been reported yet.

Embodiment Construction

[0041] 1) Select the wines from the three production areas of Shacheng, Changli and Yantai as the experimental research objects;

[0042] 2) The wine sample is digested by wet closed digestion or microwave digestion;

[0043] (1) Wet airtight digestion: Take 1-2g of grape juice / wine in a digestion tank, add 2-4mL of HNO3, put the Teflon crucible into a steel sleeve, tighten it and place it in an oven for 3 hours at 190±5°C; Cool the sample to ensure that there is no liquid on the wall of the Teflon crucible, transfer the solution into a polyethylene bottle, and dilute it with 2% HNO3 to 10-20g (the corresponding dilution factor is 10), and store it in an airtight manner. Prepare a reagent blank in the same way.

[0044] (2) Microwave digestion: Add 2.5mL wine sample into a PTFE (polytetrafluoroethylene) digestion tank cleaned by pickling, add 2.5mL nitric acid, and pre-digest in a fume hood for 15 minutes. After the acid mist disappears, digest The jars were placed in a micr...

Abstract

The invention discloses a wine origin identification technical method, relating to a wine inorganic trace element detection method and a wine origin characteristic information extraction data processing technical method, and belonging to technical field of wine product authenticity identification. The method comprises the following main steps of: a) selecting wine samples from different origins; b) performing resolution pretreatment on the samples by nitric acid; c) determining the inorganic element contents in the samples by a plasma isotope mass spectrometer; and d) after processing the obtained data, constructing a wine origin identification technical model by adopting different multivariate data processing technologies (variance analysis, principal component and neutral network), and inputting data of wine with unknown origins in the wine origin identification technical model to realize effective identification of origin attributes of wine. The wine origin identification technical method provided by the invention is beneficial to solving the technical problem of wine origin identification in China at present, and has an important significance on standardizing the wine market order.

Description

Technical field: [0001] The invention discloses a technical method for wine identification in production areas, which relates to a detection method for trace inorganic elements in wine and a technical method for identification model of wine in production areas, and belongs to the technical field of authenticity identification of wine products. Background technique: [0002] In 2006, my country's new national standard GB 15037 "Wine" clearly stipulated the concept of origin, variety and year of wine, but my country still lacks effective identification techniques and methods for origin wine. With the development of the wine industry, relying solely on corporate self-discipline and the existing standard management system cannot effectively regulate the market. Some illegal companies mark the origin on some fake and inferior products as high-quality wine sales. The impact is not conducive to the healthy development of the market. [0003] Trace inorganic elements are an importa...
