The Jeonnam Agricultural Research Institute has developed two types of "red tea liquid sticks" using concentrated red tea extract.

The Jeonnam Agricultural Technology Institute (Director Kim Haeng-ran) announced on the 24th that it has developed two types of black tea liquid sticks (lemon flavor, grapefruit flavor) using concentrated black tea extract rich in effective ingredients such as catechins. The newly developed black tea liquid sticks are characterized by the application of a fermented alcohol extraction method to increase the content of theaflavins, a representative effective ingredient of black tea, and catechins by about 2 times. In particular, the black tea used as a raw material was produced using the "rapid black tea manufacturing technology" that the Jeonnam Agricultural Technology Institute has applied for a patent, which significantly reduces the manufacturing time compared to conventional methods. This has led to cost savings and increased theaflavin content, achieving significant results from both a technological and economic perspective. Furthermore, an investigation into the inhibitory ...
