Abstract: Alcohol fermentation was carried out to extract tea-saponin based on the feature that there are a lot of saccharides substances in tea cake. The result showed that secondary fermentation could successfully promote alcohol fermentation. 12.58 g carbohydrate per 100 g cake was consumed during alcohol fermentation. The extraction percentage could reach 80%, and the purity of crude extraction could achieve 62.37%. It was appropriate when the proportioning of corn meal and cake was 1:1.5. The energy consumption of concentration was low. The concentration of tea-saponin in original extracts was 78.26 mg/mL.
