Embodiment 1
[0049] The method for preparing the concentrated high-concentration tea drink by supercritical extraction provided in this example specifically includes the following preparation steps:
[0050] S1. Raw material processing: Weigh 60 parts of brown sugar, 2.1 parts of ginger powder, 2 parts of chrysanthemum powder, 1 part of xylo-oligosaccharide powder, and 0.4 part of dentata grape leaf powder, pulverize them respectively, and pass through a 70-mesh sieve;
[0051] S2. Extraction: Mix the ginger powder, chrysanthemum powder, and snakehead grape leaf powder obtained in step S1 and pass them into a supercritical carbon dioxide extractor, add 0.7 parts of ethanol, set the extraction pressure and extraction temperature, and repeat the extraction 3 times, each time Extract for 30 minutes, the carbon dioxide flow rate is 160kg / h, and the extract is obtained; the first extraction pressure is 20MPa, the extraction temperature is 40°C, the second extraction pressure is 12MPa, the extrac...
