Tea root tea and processing technology thereof

Abstract

The present invention belongs to the technical field of agricultural product production and processing, and particularly discloses a tea root tea and a processing technology thereof. The processing technology comprises the following steps: a substrate cultivation, water cultivation or aerial cultivation method is used to use a nutritional solution to cultivate tea trees from tea tree seeds or cutting seedlings; when the tea trees grow to 20-30 cm high, young and tender new roots of the tea trees are harvested; the tea trees continue to grow; the roots are collected in batches and repeatedly used; the collected tea tree young roots are cut into root segments at 1-2 cm; the root segments are put into boiling water for 2-5 seconds; the root segments are taken out; the taken out root segmentsare threw into tap water to be cooled; the cooled root segments are centrifuged and drained at low speed; the drained root segments are placed in a low-temperature refrigerator or liquid nitrogen to be frozen; then a freeze-drying machine is used to conduct vacuum pumping and freeze-drying at a low temperature; the water content of the finished product of the tea root tea is less than 3%; the finished product of the tea root tea is vacuum packaged; and the vacuum packaged tea root tea is preserved in the dark. The tea root tea contains the basic natural ingredients of the traditional Chinese medicinal decoction pieces of the tea tree roots, especially contains relatively high content of amino acids and tea polysaccharides, is a drink having health-care functions and also being unique in taste and aroma, can be drunk alone or drunk together with the other combined materials.
