Application of Membrane Separation Technology in Black Tea Extract Processing

Crude black tea extract contains colloids and macromolecular impurities, easily generating cold haze and precipitation. Traditional thermal processing destroys natural tea aroma and active ingredients. Membrane separation enables low-temperature physical treatment. It removes unstable substances to clarify tea liquid and gently concentrates feed liquid while retaining tea polyphenols and flavor components. This technology improves product stability, reduces energy consumption and preserves original tea taste, making it a superior processing solution for black tea extract and tea beverage production.
