Abstract
The present invention discloses a nano camellia chrysantha raw powder, and its preparation includes the following steps: concentrating the extract of camellia chrysantha and spray-drying its concentrate in the spray-drying tower in the jet speed of 400-900 m/sec. at spraying temp. of 30-60 deg.c and 0.1-0.05 MPa so as to obtain the invented camellia chrysantha nano powder which is easily dissolved, and can be used as additive.
Description
One, technical field
What the present invention relates to is the former powder of a kind of nm of gold jasmine tea, is the nanoscale powder that is prepared from by the composition that extracts in the golden camellia tea.
Two, background technology
Camellia nitidissima (C.chysantha) is the plant of Theaceae Camellia nitidissima group (Camellia sect.Nitidisima Chang).Contain amino acid in its leaf, Tea Polyphenols, aromatic substance and various trace elements, has anti-cancer, suppress tumor growth, reducing blood lipid, reduce cholesterol, prevent atherosclerotic and prevent and treat effect such as prostatitis, but present utilization to Camellia nitidissima, be only limited to Camellia nitidissima is prepared into a kind of rough machined product with other raw materials, for example the patent No. is 93103963.0, name is called the Chinese patent of oral honeysuckle flower tea and preparation method thereof, with the patent No. be 93103965.7, name is called the Chinese invention patent of instant honeysuckle flower tea, disclosed is exactly the product that Camellia nitidissima prepares with other raw materials, what the production method of this product adopted then is that high temperature extracts method for concentration, this method might partly be destroyed the effective ingredient in the Camellia nitidissima, or lose, this product and method have certain limitation simultaneously, can not with other raw material compatibility again, can not become the product of other types as additive preparation.
Three, summary of the invention
Purpose of the present invention prepares the former powder of a kind of nm of gold jasmine tea exactly, and just the concentrate that will extract from golden camellia tea is prepared into a kind of nanoscale powder again.
The particularity of nanometer materials is that its material grains is of a size of the ultra-micro powder less than 100nm, its surface area is very big, the atom number ratio at crystal boundary place makes it to produce four big effects: small-size effect, quantum effect (containing macro quanta tunnel effect), skin effect and interfacial effect up to 15%-50%.The extraction preparation that nanometer technology is applied to effective ingredient in the plant can produce a kind of beyond thought effect.Therefore, for achieving the above object, the present invention has taked such measure: the former powder of a kind of nm of gold jasmine tea, be Camellia nitidissima aquatic foods leaf to be carried the extract that filters gained through alcohol extracting, water concentrate through saturating filter of low temperature again, obtain concentrate, concentrate is imported spray drying tower, carry out that the diameter of gained is 20-150nm after the spray-drying, more than 50% less than the nanoscale powder of 100nm, used preparation condition is that the effluxvelocity that concentrate sprays into is the 400-900 meter per second, vapo(u)rizing temperature is 30-60 ℃, and vacuum is 0.1-0.05Mpa in the tower.
Take the present invention of above-mentioned measure, be on the basis of common vaccum spray drying tower, increase the pressure of liquid stream with the superhigh pressure liquid pump, and be used in combination special nozzle, make it to produce the effluxvelocity that reaches the 400-900 meter per second, make ultra micro droplet instantaneous drying under 30-60 ℃ of condition and 0.1-0.05Mpa vacuum of high-speed motion, formation reaches nano level ultra-micro powder.The powder ratio of crossing 1200 mesh sieves reaches more than 85%, and color is a dark brown.Be dissolved into the present invention in 500 times the water, the solution yellowish-brown is limpid transparent, put for a long time and precipitation can not occur, local flavor is identical with Camellia nitidissima extraction Normal juice, because particle is thinner, active ingredient more helps absorption of human body in theory, thereby easilier disperses in dissolve medium, uses more convenient during as the additive of other new product developments.
