This color change in green tea leaves has perplexed scientists for many years now.The mystery of green tea turning yellow has led scientists to take a closer look at the chemical processes that occur during tea processing and storage. As it turns out, the yellowing of green tea leaves is due to the breakdown of the plant pigments known as chlorophyll, carotenoids, and flavonoids. Chlorophyll is responsible for the green color of tea leaves and breaks down during drying, which contributes to the color change. Carotenoids and flavonoids produce yellow and orange colors, respectively, and their interaction with sunlight and oxygen can lead to the yellowing of tea leaves. The rate of tea leaf yellowing is also influenced by factors such as humidity and temperature.
The Processing of Green Tea Leaves
The processing of green tea leaves is a delicate and intricate process. Each step has an impact on the final color, flavor, and aroma of the tea. Traditionally, green tea leaves are picked by hand and then steamed to prevent oxidation, which locks in the antioxidants and other beneficial compounds. The steaming process also gives the tea its characteristic grassy flavor and refreshing aroma. After steaming, the leaves are rolled and shaped into their final form, which can vary depending on the type of green tea being produced. Some teas are shaped into pellets or balls, while others are left in their natural leaf form.
Tea producers have discovered ways to manipulate the processing of green tea leaves to produce various shades of tea, including yellow green tea. One such method involves exposing the tea leaves to air for a period of time before steaming. This allows the leaves to oxidize slightly, producing a yellowish hue and a smoother, less astringent flavor. Another method involves pan-firing the leaves repeatedly until they turn yellow. The tea produced using this method has a stronger flavor and nutty aroma. These variations in processing techniques have resulted in a wide range of green tea products, each with its own unique characteristics.Continuing from the last paragraph, some other methods used in tea production include shading the leaves, which reduces the amount of sunlight they receive and increases the chlorophyll content, leading to a deeper green color. In contrast, the leaves used for white tea are often just left to wither and dry naturally without any significant processing.
There is no doubt that the production of green tea is a complex and fascinating process that involves many factors, from the quality of the soil to the specific techniques used by different producers. Nonetheless, the mystery of why green tea turns yellow remains an enigma that researchers are continually trying to solve.
