The Sun-Dried Green Maocha is crafted from fresh buds and leaves of the large-leaf tea variety in Yunnan, using a distinctive low-temperature production process. The quality of the raw material determines the upper limit of the final product's quality. The freshness of the leaves is influenced by the tea plant variety, the ecological standards of its growing environment, and the age of the tea plants, with the ecological environment being of paramount importance. The production process of Sun-Dried Green Maocha: 1. Picking: Completed in the morning when the mist disperses around 8 to 9 AM, with a slight dew, the fresh leaves picked at this time retain their tenderness. 2. Spreading Out: This step typically lasts between 6 to 8 hours, depending on the moisture content of the fresh leaves. The leaves partially lose water, becoming softer, and the stems lose their elasticity, preparing them for the next step and reducing damage. 3. Withering of Fresh Leaves: Spread thinly (3 to 5 cm) to naturally lose water. 4. Kill-green Step: Wok kill-green is a traditional method used in Yunnan tea regions. When the wok reaches a certain temperature, fresh leaves are added, focusing on keeping the leaf temperature below 60°C…

Since the weather has warmed up, the number of people engaging in outdoor activities has soared, and camping consumption has become popular.

Ellagic acid (EA) is a biologically active phenolic compound widely present in plant tissues such as fruits and nuts, with its structure shown in Figure 1. It is a dimeric derivative of gallic acid. In nature, ellagic acid mainly exists in condensed forms, such as ellagitannins. Ellagic acid is essentially non-toxic and has a significant inhibitory effect on chemically-induced carcinogenesis and various types of cancers, including colon cancer, liver cancer, lung cancer, prostate cancer, breast cancer, lymphoma, and others. Additionally, ellagic acid also exhibits antioxidant, anti-inflammatory, antibacterial, melanin inhibition, and leukemia improvement effects. Due to its excellent biological activity, ellagic acid is widely used in health foods, medicine, pharmaceuticals, cosmetics, and other fields. Studies have shown that tea is an important dietary source of ellagitannins and ellagic acid, which are converted from ellagitannins through human gut microbiota metabolism. ▲ Human Metabolic Pathway Pu'er ripened tea, a famous Yunnan tea, is a unique microbial-fermented tea made from large-leaf sun-dried green tea. The essence of solid-state fermentation in Pu'er ripened tea is primarily the result of moist heat, enzymatic actions, and microbial activities. During the fermentation process of large-leaf green teas, microbial metabolism releases a large amount of heat, and the enzymes…
