Jasmine Tea is made by blending and scenting tea leaves with fresh jasmine flowers, allowing the tea to absorb the floral fragrance [3]. Also known as Jasmine Scented Tea, it belongs to the category of scented teas. The base tea is green tea, and the finished product involves the removal of jasmine flowers, making it a type of green tea. It has a history of over 1,000 years.

The scenting process of jasmine tea primarily involves the release of fragrance from the flowers and the absorption of this fragrance by the tea base [5]. The release of fragrance from fresh jasmine flowers is a biochemical process. Under the influence of enzymes, temperature, moisture, oxygen, and other factors, mature jasmine flowers decompose aromatic substances. As physiological changes occur and the flowers bloom, they continuously emit their fragrance.

The absorption of fragrance by the tea base occurs through physical adsorption. Along with absorbing the fragrance, the tea also absorbs a significant amount of moisture. Due to the permeation of water, chemical adsorption takes place. Under warm and humid conditions, complex chemical changes occur. The tea liquor gradually changes from green to yellow and bright, and the taste transforms from light and astringent to rich and mellow, forming the distinctive aroma, color, and flavor of *** jasmine tea.
