Friendly reminder for tea franchise partners: Tea originated in China and was initially used as an offering in rituals. However, starting from the late Spring and Autumn period, it began to be consumed as food. By the mid-Western Han Dynasty, tea had evolved into a medicinal drink, and by the late Western Han Dynasty, it had become a sophisticated beverage enjoyed exclusively at court. It wasn’t until the Western Jin Dynasty that tea truly gained popularity as a common everyday drink. The earliest archaeological evidence of cultivated tea plants dates back to the Luotianshan site in Yuyao, Zhejiang Province—remains that are over 6,000 years old. Indeed, the tradition of drinking tea first took root in China. Tea leaves, typically rectangular or oval in shape, can be directly steeped in hot water. Depending on variety, production method, and final product form, tea is broadly categorized into six main types. Seasonally, tea is divided into four distinct categories: spring tea, summer tea, autumn tea, and winter tea. Additionally, there are various secondary teas created by further processing either raw or refined teas. These include floral teas, compressed teas, extracted teas, medicinal and health-focused teas, as well as tea-based beverages.

Friendly reminder for tea franchisees: Tea contains beneficial compounds such as catechins, theaflavins, inositol, folic acid, and pantothenic acid, which can help enhance overall health. As for tea beverages—tea is proudly recognized as "one of the world's three major drinks."

Friendly reminder for tea franchisees: Deep processing of tea refers to the production of tea-containing products—whether they are primarily made from fresh leaves, finished tea, or even tea-related waste and byproducts—using specialized processing techniques and methods. These products may either have tea as the main ingredient or incorporate other substances altogether. But what exactly is the significance of deep-tea processing?
First, fully leverage tea resources. Many low-grade teas, tea by-products, and tea waste currently lack direct market channels—yet they contain significant untapped potential. By investing in advanced processing techniques, we can maximize the use of these resources for the benefit of humanity, while also enabling businesses to reap substantial economic gains.
Second, it’s about enriching market offerings. Tea is certainly a wonderful product, but people are no longer content with tea simply existing as "dried leaves." Instead, they’re looking for a diverse range of tea products.
Third, by developing new functionalities, many of tea's unique benefits or effects cannot be fully realized through traditional brewing methods. However, when tea undergoes advanced processing, these features can be harnessed in a targeted and purposeful way. Additionally, combining tea with other substances during deep processing can further enhance its versatility and effectiveness. This is where advanced tea-processing technologies come into play.
According to "Advanced Tea Processing Technology," advanced tea processing techniques can generally be categorized into four main areas or types: mechanical processing, physical processing, chemical and biochemical processing, and integrated technology processing.
Tea processing using machinery refers to methods that do not alter the fundamental nature of the tea leaves. Instead, these techniques focus solely on modifying the tea's external appearance—such as its look, shape, and size—to enhance storage, ease of brewing, compliance with hygiene standards, and overall aesthetic appeal. Bagged tea is a prime example of a product created through mechanical tea processing.
Physical processing of tea leaves: Typical products include instant tea, canned tea (also instant tea), and bubble tea (prepared tea). These processes transform the original form of the tea leaves, so the final products are no longer packaged as "leaves."
Chemical and biochemical processing refers to the use of chemical or biochemical methods to create products with specific functions. Its key feature involves isolating and purifying particular components from tea raw materials for beneficial applications, or transforming the inherent nature of tea into valuable end-products. Examples include tea pigment series, vitamin series, and natural preservatives.
