Examples
Embodiment 1
[0022] Take ginseng, wash it, dry it, break it into coarse powder, reflux it with 6 times and 4 times 50% ethanol at low temperature for 1 hour, filter the extract respectively, combine and recover the ethanol, concentrate in vacuum to 1.10±0.02, filter, and then concentrate in vacuum To 1.30±0.02, add an appropriate amount of sucrose powder to the concentrated solution, mix, and make a lump that can be grasped and disperse when touched. Use a oscillating granulator to make fine granules, dry to a moisture content of less than 7%, and use the gravimetric method. Put 2g into an aluminum-plastic composite bag, then put 3g of oolong tea into it, and seal it with heat plastic. The functional tea has the function of enhancing immunity, is suitable for weak and susceptible people, has good taste and accurate dosage, and is brewed by traditional tea drinking method when used, one bag at a time.
Embodiment 2
[0024] Take Rhodiola rosea, wash it, dry it until the water content is less than 10%, crush it into a coarse powder, add 6 times and 4 times the amount of water and boil for 30 minutes, filter the extract through a 300-mesh screen, combine the extracts, and concentrate to The relative specific gravity is 1.30±0.02. Take an appropriate amount of sucrose powder, mix it, and make it into a mass that is easy to hold and disperse when you touch it. Use a oscillating granulator to make fine particles, dry it to a moisture content of less than 6%, and put a wax in every 2g / paper / PE composite film bag, then put 3g of green tea into it, and seal it. This functional tea has the functions of improving hypoxia tolerance and auxiliary protection against radiation hazards. It is suitable for people in plateaus, hiking and special industries. It has a good taste and accurate dosage.
Embodiment 3
[0026] Same as Example 1 and Example 2, wherein the extract is concentrated to a relative specific gravity of 1.1-1.2, high-speed (above 10,000rpm) centrifugal filtration, spray-dried, the dry matter is mixed with an appropriate amount of xylitol, and dry-granulated, one pack per 2g Put 3g of green tea into the wax / paper / PE composite film bag and seal it. This functional tea has the functions of improving hypoxia tolerance and auxiliary protection against radiation hazards. It is suitable for people in plateaus, hiking and special industries. It has a good taste and accurate dosage.
