Though existing many health protection tea products on the market, with Pu'er tea and Yunnan olive mutually the health protection tea of assembly preparation do not see that as yet relevant report is arranged.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, a kind of Yunnan olive health protection tea is provided, fill up the blank in market.
The present invention also aims to, a kind of method for preparing above-mentioned Yunnan olive health protection tea is provided.
Purpose of the present invention is achieved by the following technical programs.
Except as otherwise noted, percentage of the present invention is percetage by weight.
A kind of Yunnan olive health protection tea is made by following raw material: 100~300 parts of Yunnan olives, 15~40 parts of Pu'er teas.
The olive health protection tea can adopt conventional method further to be prepared into loose tea, compressed tea, instant tea, tea beverage or tea in bag in Yunnan of the present invention.
A kind of Yunnan olive bealth-care instant tea is made by following raw material: 100~300 parts of Yunnan olives, 15~40 parts of Pu'er teas, 50~80 parts of maltodextrins, 15~75 parts of STEVIA REBAUDIANA.
The preparation method of above-mentioned Yunnan olive health protection tea may further comprise the steps:
1, the Yunnan olive is with 50%~80% alcohol extract, be concentrated into proportion 1.15 ± 0.05 after, the water dissolving, supernatant is collected in static placement, is 1.25 ± 0.05 with supernatant concentration to proportion, the Yunnan Fructus Canrii Albi extract;
2, Pu'er tea use earlier cold rinse, removes impurity such as dust, uses 86 ± 3 ℃ hot water extracting 3~4 times then, filter, concentrated filtrate, dry must Pu'er tea;
3, Yunnan Fructus Canrii Albi extract and Pu'er tea are mixed, promptly get required Yunnan olive health protection tea through vacuum drying.
On above-mentioned preparation method's basis, preparation Yunnan olive bealth-care instant tea also further may further comprise the steps:
1, the STEVIA REBAUDIANA water extracts, and after being concentrated into proportion and being 1.15 ± 0.05, adopts macroporous absorbent resin that the extract column chromatography is carried out separation and purification, with 40%~70% ethanol elution, collects eluent, with eluent concentrate, dry STEVIA REBAUDIANA extracts and makes with extra care thing;
2, Yunnan Fructus Canrii Albi extract, Pu'er tea, qualities of stevia extract and maltodextrin are mixed, promptly get Yunnan olive bealth-care instant tea through vacuum drying.
The present invention has following advantage with respect to prior art:
1, this health protection tea cool taste, flavour are honest, by the synergy of Yunnan olive and Pu'er tea, make product have reducing blood lipid, anti-ageing, the effect that promotes the production of body fluid to quench thirst, detoxify.After further being prepared into instant tea, being convenient for carrying and drinking.
2, form by the natural plants of medicine-food two-purpose is refining, do not contain any chemical synthesis material in the prescription, natural environmental protection.Replace white sugar with qualities of stevia extract, satisfied many consumer groups responsive, enlarged the consumer groups of health protection tea sugar.
3, adopt macroporous adsorptive resin column technique that STEVIA REBAUDIANA is carried out separation and purification, adopt ethanol extract from water precipitation to handle the Yunnan olive, remove remaining pulp and water-fast macromolecular substances in the extract, the solubility of active ingredient and the clarity of product have been improved, human body can be absorbed fully to wherein nutrition and active component, help improving bioavilability.
4, with low cost, technology is easy, has market application foreground well.
