According to the Ministry of Industry and Trade, Vietnam is the 7th largest tea producer and 5th largest tea exporter globally with 124,000 hectares of tea growing area and more than 500 production and processing facilities, with a capacity of over 500,000 tons of dry tea /year. However, export value is often low mainly due to weakness and backwardness in planting and cultivation techniques as well as post-harvest processing and preservation.

Many solutions have been and are being proposed to improve the quality and value of Vietnamese tea. Organic farming methods are also receiving more and more attention as producers clearly realize the disadvantages of traditional agricultural farming methods and sometimes even follow VietGAP and GlobalGAP standards. However, quality assessment and management are still loose, lacking close and comprehensive combination between science and production and business.

Testing methods to manage quality from planting to harvesting and processing still have many shortcomings and lack accuracy and reliability compared to testing in developed countries. Analytical techniques to determine botanical and geographical origin have not yet been applied to prove that the product comes from Vietnam. Transparency in product information is not strictly guaranteed because the necessary tools and techniques have not been applied or have been applied but sporadically, unsystematically and without continuity throughout the farming process, processing, packaging, and export.

In tea research, different types of tea are classified based on differences and similarities in chemical constituent content (elements, polyphenol compounds and antioxidant capacity). Differences in varieties, climate, soil, farming conditions, processing and preservation methods, etc. will lead to differences in internal ingredients, sometimes this difference is so small that it requires careful analysis. Support of some mathematical tools, such as multivariate data analysis methods (chemometrics).

The results of the project will serve as a premise for building quality management standards for Vietnamese tea and improving production processes as well as managing the exploitation of raw material areas. Based on the tea traceability and quality management software platform, technology companies can develop specific applications for tea promotion and business. This helps increase awareness of tea quality in society, transparency of information, contributing to increasing competition in the market and making the value of Vietnamese tea transparent. Consumers also have access to necessary information about tea products to make choices that suit their needs.
