Instant tea today and future


Instant tea is a kind of fine powder or granular solid tea product that can be quickly dissolved in water, which is processed through extraction (juice extraction), filtration, clarification, concentration and drying. . After more than 60 years of development, traditional instant tea processing technologies and product types have basically matured. With the changes in the needs of China’s consumer market in the new era, the instant tea industry is also facing major opportunities and challenges. It analyzes and clarifies the main problems, proposes future development paths and technical requirements, and conducts relevant technical research in a timely manner to better It is of great significance to solve the upstream low-end tea outlets and promote the sustainable development of the instant tea industry.
