Embodiment Construction
[0039] A process for the integrated extraction of multiple bioactive components in tea, comprising the following steps:
[0040] The tea leaves are dried, crushed, passed through a 60-mesh sieve, and filtered to obtain tea powder.
[0041] Take 10kg of tea powder, add it to the processing barrel, add pure water to 100L, heat to 80°C-90°C, keep stirring and extracting for 30min during the heating process, and then perform solid-liquid separation to obtain the first solid-phase separation and the first liquid phase separation.
[0042] The first liquid phase separation is filtered, concentrated by evaporation and dried to obtain concentrated instant tea. Specifically, the plate and frame filter press is used to separate the liquid phase and the solid phase first, and an appropriate amount of pure water is used for top pouring, and the pouring liquid is merged into the liquid phase. After that, the liquid phase passes through a ceramic membrane with a pore size of 50 μm to obtai...
