Problems solved by technology

However, the "Hygienic Requirements for Plant Beverages" only set requirements for raw and auxiliary materials, sensory indicators, hygienic physical and chemical indicators, microbial indicators, and food additives for plant beverages, and did not reflect the quality control standards for effective chemical components from the ingredients of Chinese herbal medicines. Using only essence, white sugar, water, etc. to prepare counterfeit plant beverages is an opportunity, which is not conducive to protecting consumers' rights and safety and health, nor is it conducive to maintaining the reputation of specific brand plant beverages

Abstract

The invention discloses a method for building quality control chromatography fingerprint maps of traditional Chinese medicine herbal tea and herbal medicine beverage products. The method comprises the steps of: (1) preprocessing a sample and processing the sample by one method selected from following methods: (1) a freeing, drying-extracting method, (2) a thermal evaporating, drying-extracting method, and (3) a solid-phase extraction method; (2) conducting HPLC (high performance liquid chromatography) fingerprint map analysis. According to the method, the quality control chromatography fingerprint maps of the traditional Chinese medicine herbal tea and herbal medicine beverage products built by the method disclosed by the invention can be used for carrying out macroscopic and fine constituent quality control on the product, and the blank that the Chinese herbal medicine beverage such as the traditional Chinese medicine herbal tea and herbal medicine herbal tea only has requirements on raw material and auxiliary material, sensory indexes and health indexes in quality control, but has no macroscopic quality control indexes of related phytochemical constituents at present is filled.

Description

technical field [0001] The invention relates to a construction method of quality control chromatographic fingerprints, in particular to a construction method of quality control chromatographic fingerprints of traditional Chinese herbal tea and herbal beverage series products. Background technique [0002] my country's beverage industry is a new industry developed after the reform and opening up. It started relatively late, but developed very rapidly. The total output of beverages in the country maintained a sustained and steady growth. [0003] As people's awareness of health increases, people begin to choose healthy drinks, and the demand for Chinese herbal teas and herbal drinks is also increasing. However, the current quality control of Chinese herbal teas and herbal beverages is based on the content of a certain component as an indicator, or focuses on sensory indicators, some physical and chemical indicators, microbial indicators, etc., and there has been no standard t...
