  Chinese Plant Extract Manufacturers can generally be divided into four tiers. The first tier includes A-share listed companies such as Layn   Natural Ingredients   and Chen Guang Biotechnology Group (CCGB), which are technologically advanced, have large-scale operations, and have high visibility. The second tier consists of some New Third Board-listed companies, such as Day Natural, and Red Star Pharmaceutical, which have a certain level of visibility and are continuously expanding in scale. The third tier includes companies like BGG WORLD and JOYWIN Natural Products, recognized by the industry, while the rest are relatively weaker players in the fourth tier. Plant Extract Manufacturers typically feature the following main characteristics and equipment: Extraction equipment: These devices are used to extract useful compounds from plant materials. Extraction processes can utilize various methods such as solvent extraction, supercritical fluid extraction, and distillation...

Instant tea is a type of solid tea beverage that quickly dissolves in water. Using finished tea, semi-finished tea, tea by-products, or fresh leaves as raw materials, it undergoes processes such as extraction, filtration, concentration, and drying to produce a new type of beverage in granular, powdered, or small flake form that easily dissolves in water without leaving tea residue. It boasts advantages such as convenience in preparation, absence of pesticide residues, and versatility in flavors, including pure teas like instant black tea, green tea, Tieguanyin, oolong tea, jasmine tea, pu-erh tea, as well as flavored teas like lemon black tea, milk tea, and various fruit-flavored instant teas. Introduction: Instant teas are categorized into cold-soluble and hot-soluble types based on their solubility. Internationally, the price of instant tea is about 10 times that of dry tea. Consumption tends to be higher in developed countries; for instance, in the United States, consumption account...
