China Food Industry Association Liquor Professional Committee on the 8th launched China's first method to identify the aging of liquor - "volatile coefficient identification method", this identification method was invented by the Sichuan Jiannanchun winery, has applied for national invention patents, this The product standard has been used to produce 15 years of Jiannanchun liquor. According to Ma Yong, Deputy Secretary-General of the China Food Industry Association and Executive Vice Chairman of the Chinese Liquor Professional Committee, the white spirits, with the extension of storage time, have a soft, mellow and fragrant flavor. Since the late 1990s, well-known liquor companies such as Kweichow Moutai and Wuliangye have adopted years of distilled spirits as a method of separating product quality, grades, and prices. In combination with traditional Chinese techniques, they have introduced ten years and twenty years of aging. Liquor is welcomed by high-end consumer groups. Individual famous brand wines are even in short supply. According to a recent sample survey conducted by the China Food Industry Association, nearly 60 percent of the top 100 liquor companies in China have launched vintages with annual sales of at least 5 billion yuan. Mr. Qiao Tianming, chairman of Sichuan Mianzhu Jiannanchun Winery Co., Ltd., introduced Jiannanchun in recent years to invest nearly RMB 100 million in special funds. He has conducted many explorations and researches on vintage liquors. Researchers have started with the volatile characteristics of trace flavors in liquor after many years. The follow-up test found that with the prolongation of liquor storage time, the association between trace aroma substances, alcohol molecules and water molecules in the wine body is even closer. At the same time, the longer the storage time of liquor, the lower the volatilization coefficient of trace aroma in wine body with the prolonged storage time. According to this method, it is only necessary to determine the volatilization coefficients of certain substances of the liquors to be identified and compare them with the standard curve of storage time to obtain the year of production of the liquors. In the application, the volatilization coefficients of different trace components in wines of different specifications and storage time are determined, a corresponding database is established, and the volatility coefficients of certain trace components in the wines to be identified are compared with the data in the corresponding database. The corresponding storage time is displayed. This method is fast, accurate, convenient, sensitive, and has strong applicability. It breaks through the problems that have long puzzled the identification of aged wines, and provides a scientific basis for the production and testing of vintages. In the experiment, researchers conducted research tests on dozens of vintages that were sold well in the market and found that Wuliangye, Kweichow Moutai, and other vintages had similar volatility curves.
