Abstract
The invention relates to a method for extracting tea polysaccharides from sesame meal of oiltea camellia. The sesame meal of the oiltea camellia is dipped in water according to a proportion of the sesame meal of the oiltea camellia of 10Kg to water of 100-200L and then heated and mixed. Filtration is done when the mixture is still hot and the filtrated solution is continuously heated to be concentrated to one fourth of the original volume; yeast is then added to the concentrated solution which is then kept at the temperature of 25-32 DEG C for vibrating fermentation for 0.5-3 days. After the vibration is stopped, the solution is precipitated and the upper clear solution is obtained and mixed with ethanol with a volume of three times as that of the clear liquid; next the mixture of the clear liquid and the ethanol is placed in a refrigerator for freezing; water is added to the frozen liquid obtained from the freezing step so as to dissolve and precipitate the frozen liquid and then take the upper layer liquid; the tea polysaccharides are finally obtained from the upper layer liquid after sprayed and dried. The invention solves the problem of complex technique, more production equipment and high production cost of the existing method for extracting tea polysaccharides from the sesame meal of the oiltea camellia.
Description
Technical field
The invention belongs to biochemical field, particularly a kind of is the method that raw material extracts tea polysaccharide with the camellia seed meal.
Background technology
Countries in the world are all in the research of extensively carrying out tea polysaccharide and application work at present.Because of tea polysaccharide is made up of monose such as glucose, arabinose, rhamnose, sweet sugar, ribose, wood sugars.It has clinical proof anticoagulant, hypoglycemic, reducing blood lipid, hypotensive, the anti-width of cloth and penetrates, and it can prevent and treat angiocardiopathy and diabetes, and malignant tumour is had the supplemental treatment effect, and it can treat cancer and the damaged disease of panimmunity that body rabbit epidemic disease system sustains damage.Tea polysaccharide has that using dosage is little, malignant boil is imitated remarkable, nontoxic pair of advantage such as effect.Our tea polysaccharide extract from tealeaves, tealeaves seed, the tea seed oil dregs of rice at present.Save the cost except from the tealeaves seed dregs of rice, refining, from tea time, tealeaves seed, refine and cause the wasting of resources and cost to improve.There is rich in natural resources in oil tea seeds of trees China, but is utilized by the camellia seed meal end after the oil expression, causes significant wastage.The tea polysaccharide that contains more composition in the camellia seed meal in recent years by being it is found that, but extracts the method for tea polysaccharide at present from camellia seed meal, complex process, and production equipment is many.
Summary of the invention
The objective of the invention is to overcome the method for from camellia seed meal, extracting tea polysaccharide at present, complex process, the deficiency that production equipment is many provides a kind of technology simple, the extracting method that production equipment is few.
Technical scheme of the present invention is: camellia seed meal is soaked in water, heats, boils, filters then add yeast ferment in solution, separate with centrifuge, impurity is removed, in clear liquid, add ethanol, naturally the freezing form slurry in cooling back becomes sugar juice after adding water, and post precipitation is removed albuminate, liquid is concentrated, and spray-drying gets tea polysaccharide.
Remarkable result of the present invention: make full use of camellia seed meal, turn waste into wealth, technology is simple, and production equipment is few, and production cost is low, and is workable.
The specific embodiment
With camellia seed meal in the ratio of 10Kg than 100-200 premium on currency, in water, soaked 1-2 days, heat then, be stirred to pasty state simultaneously, stop heating, filter while hot, remove the undissolved seed dregs of rice and impurity, treat to re-use next time, the liquid after filtering is continued heating, make liquid concentration to 1/4 volume, when treating that solution is cooled to 25-32 ℃, in the solution that concentrates, add the yeast of 0.1%-0.6%, remain under the 25-32 ℃ of temperature, the vibration fermentation, fermentation time is decided on temperature, 0.5-3 after it, stop vibration, make its precipitation, get the ethanol that supernatant liquor adds 3 times of clear liquid volumes, stirred 5-10 minute, it is freezing to put into refrigerator, freezing liquid is added water make its dissolving layering and precipitating.Get supernatant liquid, remove lower floor's albuminate, with the spray-dried tea polysaccharide that gets of supernatant liquid.
Claims (2)
1. method of from camellia seed meal, extracting tea polysaccharide, it is characterized in that: with camellia seed meal in the ratio of 10Kg than 100-200 premium on currency, in water, soaked 1-2 days, heat then, be stirred to pasty state simultaneously, stop heating, filter while hot, remove the undissolved seed dregs of rice and impurity, continue to add the liquid after filtering ripe, make liquid concentration to 1/4 volume, when treating that solution is cooled to 25-32 ℃, the yeast that adds in the solution that concentrates remains under the 25-32 ℃ of temperature, the vibration fermentation, after fermentation time 0.5-3 days, stop vibration, make its precipitation, get the ethanol that supernatant liquor adds 3 times of clear liquid volumes, stirred 5-10 minute, it is freezing to put into refrigerator, freezing liquid is added water make its dissolving layering and precipitating, get supernatant liquid, with the spray-dried tea polysaccharide that gets of supernatant liquid.
2. by the described method of extracting tea polysaccharide from camellia seed meal of claim 1, it is characterized in that: the yeast amount that adds in concentrated solution is 0.1%-0.6%.
