Description
Technical field
The present invention relates to a kind of technique extracting high-purity tea saponin from Semen Camelliae grouts.
Background technology
Tea oil tree is a kind of woody oleiferous plants resource that China is exclusive, contains the Saponin of 10%～20%, be tea saponin in cake of camellia oleifera seeds
An important sources, except this is possibly together with the polysaccharide of high level, protein.The development of oil tea plantation must pay attention to Semen Camelliae
Comprehensive development and utilization, the comprehensive benefit that the most just oil tea can be made to plant is embodied further.Current present situation is big
Part grouts are taken as fuel to burn, or inexpensively export to the countries and regions such as Japan, Southeast Asia, and this situation should be changed
See.
Tea saponin is a kind of five rings three note class material, has hydrophilic sugar body and hydrophobic coordinating group, is therefore
A kind of excellent natural nonionic surfactant, have emulsifying, disperse, moisten, the surface-active action such as foaming and anti-
Ooze, antiinflammatory, the pharmacological function such as analgesia, and have sterilizing pesticide and stimulate the function of certain plants growth, thus being widely used in
Daily use chemicals, pesticide, food and medicine and other fields China oil tea aboundresources, be the big export country of a thick saponin, but typically export
Inferior tea Saponin shade deviation, purity is low, unstable properties.Tea saponin extracting method is a lot, but generally with water extract method, organic
Based on solvent method and three kinds of methods of absorption method.Hot water extraction, aquiferous ethanol and aqueous methanol organic solvent extraction are tradition
Saponin extracting method.But this method shortcoming is it will be apparent that be on the one hand that methanol self problem makes product quality be difficult to completely
Foot market demands, particularly methanolic extract have niff, are not green products, greatly limit this product further
Exploitation application；On the other hand, its product cost is high so that final products price is high, and product is lacked competitiveness, the largely upper limit
Make the application of product.
Summary of the invention
For the shortcoming of prior art, the present invention proposes a kind of technique extracting high-purity tea saponin from Semen Camelliae grouts, should
Technique is to use water preparation leaching technology to carry out Semen Camelliae grouts just to extract, and pretreated feed liquid is carried out by recycling ultrafilter membrane
Concentrate refined, cross filter pulp after concentration being refined and be spray-dried, prepare high-purity tea saponin.
The present invention is achieved through the following technical solutions:
A kind of technique extracting high-purity tea saponin from Semen Camelliae grouts, comprises the steps:
(1) select materials: selecting defat cake of camellia oleifera seeds is raw material；
(2) crush, grind: cake of camellia oleifera seeds is uniformly crushed, and be milled to granularity less than 1.5mm；
(3) extraction: use secondary extraction, head time extraction is 1:3～6 with the ratio of water, and secondary extraction material with the ratio of water is
1:4～7, filters to get filtrate, and extraction temperature is 50～90 DEG C, uses circulation immersion method to operate, in extraction production process not
Must with copper, ferrum, etc. metal contact；
(4) flocculate and separate: using flocculant, carry out flocculating sedimentation, make starch and protein colloid be eliminated, after sedimentation,
Centrifugation, one or more of employing ammonia, Alumen or anionic amide；
(5) pre-flock, fine straining: after pre-flock, fine straining two step, removes clean by particle, and after fine straining, feed liquid is settled solution；
(6) embrane method is concentrated by ultrafiltration refined: first passes through embrane method ultrafiltration, prepared filter pulp, and reconcentration refines, and the pressure of membrane flux is
0.14～0.16MPa, the single membrane filtration time is 120～160 minutes, after ultrafilter membrane uses, by Membrane cleaning, regeneration, repeats to make
With；
(7) it is spray-dried, prepares high-purity tea saponin.
Beneficial effects of the present invention: (1) present invention uses and extracts at the beginning of water preparation leaching technology, recycles high-tech ultrafilter membrane and carries out
Concentrating refined, the product earning rate prepared is high, and purity is high, lighter color, stable performance；(2) production process does not use organic molten
Agent, harmful effect and the consumption of production cost to environment, all it is greatly lowered than Conventional processing methods；(3) feed liquid is through embrane method
It is concentrated by ultrafiltration, can reach the cocnentration factor of 8 ~ 13 times；(4) present invention uses the tea saponin that embrane method ultrafiltration is obtained, and purity can reach
More than 80%, and use the tea saponin purity of traditional method for extracting to be only 40% ~ 60%.
