Abstract


Sweet tea was introduced in this paper the traditional hot water extraction and microwave assisted extraction technology, and are compared, and the results show that the microwave assisted extraction can achieve high efficiency, energy saving effect. Through orthogonal test the results of state parameter optimization, namely microwave power is 300 w, the extracting time is 8 min, tea than 1:30. Combination parameters of this technology, the leaching process as a reference for sweet tea industry. Then the sweet tea after leaching solution ultrafiltration and reverse osmosis concentration, the osmotic pressure and the membrane. Using single-chip microcomputer control WZN food rheology instrument measuring the rheological property of different concentrations of sweet tea in solution, according to the results of the rheology analysis of molecular weight were used to 60000 mol, membrane filter, the extraction process of ultrafiltration can as far as possible keep relatively high temperature; Reverse osmosis using pressure section 2 levels of enrichment, lays the foundation for further deep processing of the sweet tea solution.
