Abstract

The invention belongs to the technical field of liquor tracing, and discloses a Maotai-flavor liquor tracing method and system based on rare earth element detection. The Maotai-flavor liquor tracing system based on rare earth element detection comprises an information acquisition module, a liquor pretreatment module, a rare earth element content detection module, an organic acid determination module, a main control module, a data statistical analysis module, a liquor traceability module, a comprehensive evaluation module, an anomaly early warning module, a data storage module and a display module. According to the physical and chemical properties of Maotai-flavor liquor and the gas chromatography combustion isotope ratio mass spectrometry technical characteristics, high-precision analysisand determination of the [delta]13C value of the organic acid in the Maotai-flavor liquor are achieved, liquor sample pretreatment is not needed before determination, and the method and system have the advantages of being simple, rapid, accurate, small in sample dosage and the like; and the evaluation module effectively solves the problem that the current evaluation system contains fewer types ofwhite spirit, can provide scientific, objective and comprehensive evaluation for consumer groups, and is convenient to select.

Description

technical field [0001] The invention belongs to the technical field of liquor traceability, and in particular relates to a sauce-flavored liquor traceability method and system based on rare earth element detection. Background technique [0002] Baijiu is the general term for Chinese alcoholic beverages (except fruit wine and rice wine), also known as Shaojiu, Laobaigan, Shaodaozi, etc. Chinese liquor has a compound aroma with esters as the main body. It uses koji and distiller's mother as saccharification starter, uses starchy (sugar) raw materials, and is brewed through cooking, saccharification, fermentation, distillation, aging and blending. Liquor. Strictly speaking, the blended wine blended with edible alcohol and edible spices cannot be regarded as liquor. Liquor is mainly concentrated in the upper reaches of the Yangtze River and the Chishui River Basin in Renhuai, Guizhou, Yibin, Sichuan, and Luzhou, Sichuan. The triangle area has the world's largest and best quali...
