Embodiment Construction

[0006] The Camellia oleifera seed meal is soaked in water for 1-2 days according to the ratio of 10Kg to 100-200 liters of water, then heated, stirred until it becomes a paste, stop heating, and filter while it is hot to remove undissolved seed meal and impurities. To be used again next time, continue to heat the filtered liquid to concentrate the liquid to 1 / 4 volume. When the solution is cooled to 25-32°C, add 0.1%-0.6% yeast to the concentrated solution and keep it at 25 At -32°C, ferment with vibration. The fermentation time depends on the temperature. After 0.5-3 days, stop the vibration and make it precipitate. Take the supernatant and add ethanol that is 3 times the volume of the supernatant, stir for 5-10 minutes, and put it in the refrigerator. Freeze inside, add water to the freezing solution to dissolve the layered sediment. The upper layer liquid is taken, the lower layer denatured protein is removed, and the upper layer liquid is spray-dried to obtain tea polysacc...

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 [0001] The invention belongs to the field of biochemistry, and in particular relates to a method for extracting tea polysaccharides from camellia oleifera seed dregs. Background technique [0002] At present, countries all over the world are extensively carrying out the research and application of tea polysaccharides. Tea polysaccharides are composed of monosaccharides such as glucose, arabinose, rhamnose, glycose, ribose, and xylose. It has been clinically proven that it has anti-blood coagulation, lowering blood sugar, lowering blood fat, lowering blood pressure, and anti-radiation. It can prevent and treat cardiovascular diseases and diabetes, and has an auxiliary therapeutic effect on malignant tumors. It can treat cancers and Various immunodeficiency diseases. Tea polysaccharides have the advantages of small dosage, significant curative effect, and non-toxic side effects. At present, our tea polysaccharides are extracted from tea leaves, tea seeds, an...
