The invention discloses a kind of Olive tea treasure and preparation method thereof, the problems such as nutritional ingredient existing in the prior art is few, impurity is more, poorly water-soluble, unobvious fragrance can be overcome.Include the following steps: that pure water is put by the preparation of 1) Pu ' er tea powder to be heated to boiling in extractor, ancient tree Pu'er tea will be chosen to be added in extractor, extracting solution is placed in taper settling tank twice, lotion is concentrated under reduced pressure into supernatant resulting after filtering under vacuum later, it is dry finally by spray drying tower, Pu'er tea tea powder is made；2) olea europaea fruit is chosen in the preparation of olive polyphenol, crushes, and pure water stirring is added, coarse filtration goes out insoluble solid substance, and by filtrate by flame filter press, resulting supernatant is concentrated under reduced pressure into lotion later, it is dry finally by spray drying tower, olive polyphenol powder is made；3) proportional arrangement that olive polyphenol powder obtained above and Pu ' er tea powder are 1:3 according to weight ratio by the configuration of Olive tea treasure.

Description

A kind of Olive tea treasure and preparation method thereof

Technical field

The present invention relates to olives and tealeaves food processing technology field, especially relate to Olive tea treasure and preparation method thereof.

Background technique

Currently known tea treasure is simply to extract tealeaves, weighs a certain amount of tealeaves, is added by the solid-liquid ratio of design A certain amount of water, decocting time are mostly 2 hours, and extraction time is mostly 3 times, 100 DEG C of Extracting temperature or so, straight after combined extract Filter is taken over, the lotion of certain weight proportion is finally condensed into normal pressure concentrator, then dry, crushing, packaging, sale.

The major part tea polyphenols when high temperature extracts of the tea treasure made from above-mentioned well known technology are destroyed, and water-soluble miscellaneous Matter is more, and except nutritional ingredient is reduced, impurity is more outer, also reduces its mouthfeel, and the solubility of finished product substantially reduces.Furthermore There was only the part nutritional ingredient in single tea in these products, mouthfeel is single tasteless.

Summary of the invention

In order to overcome the problems such as nutritional ingredient existing in the prior art is few, impurity is more, poorly water-soluble, unobvious fragrance, It is precious that technical problem to be solved by the invention is to provide a kind of Olive teas, and provides the preparation method of Olive tea treasure.

The present invention is using the basic conception of technical solution: a kind of preparation method of Olive tea treasure includes the following steps:

1, pure water is put by the preparation of Pu ' er tea powder is heated to boiling in extractor, and the ancient tree Pu'er tea chosen addition is mentioned It takes and is stirred in tank 3-5 minutes, wherein the weight ratio of pure water and Pu'er tea is 8:1-10:1, after being kept for temperature extraction 10-12 minutes First pass extracting solution is released, the pure water of same amount is added herein in puer tea slag, is heated to 90 DEG C or so, keeps temperature 30- After 35 minutes, second time extracting solution is released；Merge extracting solution twice to be placed in taper settling tank, diatomite is added as sedimentation agent And stir 15-20 minutes, it stands to allow for 8-9 hours and its natural cooling and precipitate；Later by 800 mesh flame filter presses, sunk Starch and extracting solution separation, supernatant resulting after filtering is concentrated under reduced pressure under the vacuum of -0.08Mpa to -0.09Mpa later The lotion for being 1.11-1.12 at Baume degrees, it is dry finally by spray drying tower, Pu'er tea tea powder is made；

2, olea europaea fruit is chosen in the preparation of olive polyphenol, is crushed, and pure water is added and stirs 2-3 hours, makes wherein water-soluble Property polyphenol be fully dissolved out, coarse filtration goes out the insoluble solids substance such as olive fruit stone and pulp, by filtrate pass through 800 mesh plate-frame filterings Its impurity and aqueous solution are completely separated by machine, are later depressurized supernatant resulting after filtering under the vacuum of -0.08Mpa dense Shorten the lotion that Baume degrees is 0.01-0.012 into, it is dry finally by spray drying tower, olive polyphenol powder is made；

3, olive polyphenol powder obtained above and Pu ' er tea powder are 1:(2.5- according to weight ratio by the configuration of Olive tea treasure 3.5) proportional arrangement, mixes well, and then packs.

Preferably, the weight of the diatomite is 0.01-0.012 times of extracting solution.

Preferably, the weight ratio of the olive polyphenol powder and Pu ' er tea powder is 1:3.

A kind of Olive tea is precious, is prepared by the above method.

The invention has the advantages that passing through soak extraction, impurity separation, vacuum concentration, wink-dry technology and nutrition It is uniform that ingredient deploys Olive tea treasure's color obtained, is in bronzing, and it is slightly sour puckery to brew rear mouthfeel, contains while tea perfume containing Pu'er Have the faint scent of light olive, dissolubility is high, rich in the effectively nutrition such as oleuropein, hydroxytyrosol, olive brass, tea polyphenols at Point, softening cardiovascular and cerebrovascular, anti-aging, prevention of arterial gruel type and other effects can be reached while having tea.

Specific embodiment

Below with reference to embodiment, the invention will be further described, and the scope of protection of present invention is not limited to implement The range of example expression.

A kind of preparation method of Olive tea treasure, includes the following steps:

1, pure water is put by the preparation of Pu ' er tea powder is heated to boiling in extractor, and the excellent ancient tree Pu'er tea chosen is added Enter to stir in extractor 3-5 minutes, wherein the weight ratio of pure water and Pu'er tea is 8:1-10:1, is kept for temperature extraction 10-12 points First pass extracting solution is released after clock, and the pure water of same amount is added herein in puer tea slag, is heated to 90 DEG C or so, keeps temperature After 30-35 minutes, second time extracting solution is released, merges extracting solution twice and is placed in taper settling tank, diatomite is added as heavy Depressant prescription simultaneously stirs 15-20 minutes, and wherein 0.01-0.012 times of the weight raw material of diatomite, stands 8-9 hours and make it naturally cold But it and precipitates；Later by 800 mesh flame filter presses, is precipitated and extracting solution is completely separated；Later by filtered supernatant The lotion that it is 1.11-1.12 at Baume degrees that liquid is concentrated under reduced pressure under the vacuum of -0.08Mpa to -0.09Mpa, finally by setting Inlet temperature is 220 DEG C -230 DEG C, it is dry as 100 DEG C -120 DEG C of spray drying tower to set outlet temperature, and instant capacity is made, contains Measure higher and aromatic taste Pu'er tea tea powder.

2, excellent olea europaea fruit is chosen in the preparation of olive polyphenol, is crushed, a certain amount of pure water is added, stirs Mix 2-3 hours, make wherein water-soluble polyphenols adequately dissolve out, coarse filtration goes out the insoluble solids substance such as olive fruit stone and pulp, will Its impurity and aqueous solution are completely separated by filtrate by 800 mesh flame filter presses；Later by filtered supernatant- Reduced pressure is the lotion of 0.01-0.012 at Baume degrees under the vacuum of 0.08Mpa, is 220 DEG C finally by inlet temperature, goes out The spray drying tower that mouth temperature is 100 DEG C is dry, and the olive polyphenol powder being worth with better nutritivity is made.

3, olive polyphenol powder obtained above and Pu ' er tea powder are 1:3 according to weight ratio by the configuration of Olive tea treasure Proportional arrangement, mix well, then pack.

A kind of Olive tea is precious, is prepared by the above method.
