Description
Technical field
The invention belongs to and prepare instant tea field, be specifically related to a kind of instant olong tea powder and preparation method thereof.
Background technology
Oolong tea is characteristic tea and the advantage tea of China, think except having benefit of refreshing oneself, allaying tiredness, promote the production of body fluid outside the health care such as diuresis, antipyretic sunstroke prevention, also outstanding behaviours is at anti-cancer, blood fat reducing, anti-ageing special efficacy of waiting for a long time, and the oolong tea finished product on market generally selects the Folium Camelliae sinensis that blade is complete, tea quality is high, the materials such as fannings cause because not being effectively utilized and greatly waste, and instant tea powder both can make full use of the materials such as fannings, increase operation rate, there is due to its instant capacity again portability and convenience, there is wide market prospect.
The materials such as milk flavour are added in the preparation of current instant tea powder mostly, although mouthfeel is sweeter, it is easy to accepted by the public, but greatly reduce the nutritive value of tea powder, reduce the delicate fragrance mouthfeel of tea powder.
In instant tea powder, add Chinese medicine ingredients, improve nutritional labeling and the health care of instant tea powder, it has also become a kind of important trend prepared by instant tea powder.But the problem that this preparation method needs solution is: improve the storage life of tea aroma and Folium Camelliae sinensis；The Chinese medicine ingredients of raising instant tea powder efficiency in extraction process；Tea powder and the molten fully altogether of Chinese medicine ingredients is made to mix mutually；Improve tea powder instant capacity in brewing process and dissolution rate.
Chinese patent CN201410275502.5 discloses a kind of milk flavoured type instant oolong tea powder and processing method thereof, down payment kwan-yin oolong tea 30%～40%, Tieguanyin oolong tea 40%～50%, gold tawny daylily oolong tea 10%～20% ratio to carry out raw material assorted, be then passed through enzymolysis processing, extraction, fragrance reclaims, tubular type separates, cryogenic vacuum concentrates, added to by recovery fragrance in concentrated solution, add the operations such as crude milk essence, vacuum lyophilization, process energy rapid solution in water, have the instant oolong tea tea powder of natural milk, tea perfume.But this patent exists, and raw material availability is low, the problem of tea powder extraction efficiency difference.
Chinese patent CN200610036935.0 discloses a kind of health-care tea powder, offering sacriffices to the gods or the spirits of the dead sub-powder, Mulberry Leaf, Flos Chrysanthemi Indici powder, American Ginseng powder including green tea powder, Alose, Cassia Seed, structure, the weight ratio of each powder is as follows: green tea powder 500～800 parts, Alose 50～150 parts, Cassia Seed 20～50 parts, structure offer sacriffices to the gods or the spirits of the dead 5～10 parts of sub-powder, Mulberry Leaf 2～5 parts, 1～3 part of Flos Chrysanthemi Indici powder, American Ginseng powder 1～3 part.But the technical issues that need to address in tea powder preparation process are not improved by this patent, and it is poor that made tea powder brews rear dissolution rate.
Therefore, need to invent the instant olong tea powder that a kind of raw material availability is high, tea powder extraction efficiency is high, Chinese medicine ingredients extraction efficiency is high, and the technical issues that need to address in instant tea powder preparation process are improved, improve instant capacity and the dissolution rate of instant tea powder.
