Tea - Black Tea Extract Production Process

The production process of black tea extract typically includes the following steps:

1. Harvesting Fresh Leaves: Tender leaves from the tea tree are selected as raw materials, usually harvested in the morning to ensure the freshness and integrity of the tea's nutrients.
2. Withering: The harvested tea leaves undergo withering, generally by natural or artificial methods, to promote changes in the internal chemical composition and the release of volatile substances.
3. Rolling and Fermentation: Withered tea leaves are rolled to break down cell walls and promote internal chemical reactions for fermentation.
4. Fermentation Process: The rolled tea leaves undergo fermentation, with temperature, humidity, and air circulation adjusted to enhance enzymatic activity, leading to the development of specific aromas and flavors.
5. Firing: The fermented tea leaves are fired to halt the fermentation process, preserving the color, aroma, and taste of the tea.
6. Crushing and Extraction: After firing, the tea leaves are crushed into a powder, increasing extraction efficiency.
7. Solvent Extraction: An appropriate solvent (such as water or ethanol) is used to extract effective components from the tea powder.
8. Concentration and Solvent Removal: The extract is concentrated to remove excess solvent, resulting in pure tea extract.
9. Filtration and Purification: The concentrated tea extract undergoes filtration and purification to remove impurities and insoluble substances.
10. Spray Drying: Finally, the purified tea extract is spray-dried into a powder, facilitating packaging and storage.

Through these processes, high-quality black tea extract is produced, retaining the nutritional components and natural flavors of the tea, suitable for applications in the food, health supplement, and cosmetics industries.

Tea - Black Tea Extract Source Plant Introduction, Distribution, and Growing Environment

Black tea extract is derived from the leaves of the tea tree, which is an evergreen plant scientifically known as Camellia sinensis. Below is an introduction to the source plant of black tea extract, its distribution, and growing environment.

1. Source Plant: The tea tree (Camellia sinensis) is the source plant for black tea extract, belonging to the Theaceae family and the genus Camellia. The leaves of the tea tree are the raw material for tea production, and extracting effective components from the tea leaves yields black tea extract.
2. Distribution: The tea tree is native to the southwestern region of China but has gradually spread worldwide. It is now widely cultivated across various regions globally, with significant distribution in countries such as China, India, Sri Lanka, Japan, Kenya, and Malaysia. China is one of the original habitats and major tea-producing countries, boasting abundant tea tree resources and a long cultivation history.
3. Growing Environment: The tea tree adapts to various climatic and soil conditions and has different cultivation methods depending on the region. Generally, tea trees prefer a warm, humid climate, with the ideal growing environment found in mountainous areas between 800 to 2000 meters in elevation. They thrive in sunny, damp locations with loose, well-draining soil. Provinces in China such as Yunnan, Fujian, Anhui, Zhejiang, and Hubei are major tea cultivation areas where the climate and soil conditions are highly suitable for tea tree growth.

The growing environment of the tea tree significantly impacts the quality and yield of tea leaves, and thus it is important to choose appropriate geographic locations and cultivation methods to ensure high-quality tea leaves and bountiful harvests. As one of the world’s important economic crops, the tea tree not only provides beverages but also has extensive applications in medicine and beauty.

Tea - Black Tea Extract Processing and Storage

The processing of black tea extract mainly includes the steps of harvesting, withering, rolling, fermentation, and firing. First, fresh tea leaves are harvested, then subjected to withering and rolling to gradually soften the leaves, encouraging the internal cell juices to evaporate, accelerating the activity of oxidase to produce pigments, and creating the unique flavor of black tea. Fermentation is then controlled by monitoring temperature and humidity to facilitate oxidation reactions among the tea components, followed by firing to dry the tea leaves and prevent mold growth.

Regarding storage, black tea extract should be kept in a cool, dry, and well-ventilated place, away from direct sunlight and humid environments. It should also avoid contact with strongly scented materials to prevent altering its aroma. Proper sealing can effectively reduce oxidation reactions and extend the shelf life of black tea extract. Under suitable storage conditions, black tea extract can be preserved for an extended period while maintaining its original aroma and nutritional components.
