Production technology of highly-fragrant and cold water-solutable instant tea & concentrated tea juice

The new products, highly-fragrant and cold water-soluble instant teas and concentrated tea juice were recently developed by ITR through employing new techniques of low temperature extraction and combination of membrane and enzyme. The processing of raw materials (green tea) was accordingly modified and improved to meet the special requirements for production. The new technology well solved the problems of weak aroma and weak solubility found in most instant teas.
