The product is rich in protein, phosphorus, choline and trace elements and has the health functions of promoting intelligence growth, nourishing brain, resisting senility, invigorating heart, promoting blood circulation, etc.
Description
The invention relates to the extraction process of a kind of longan, more particularly about a kind of longan polysaccharide extracting process.
Longan aril Arillus Langan is the arillus of sapindaceous plant longan DimocanpusLangan Lour.Longan is one of four your name fruit of China people high praise, and Chinese materia medica claims that longan aril is garden, an osmanthus meat.Longan flavor sweet flat, nontoxic, go into spleen, the heart channel of Hang-Shaoyin.Ming Dynasty pharmacy man LI Shi-Zhen has been given very high evaluation to the nutritive value of longan with to the effect of human health, and he says in Compendium of Material Medica: food is expensive with lichee, and intelligence development then longan is good.LI Shi-Zhen is also pointed out: it is clever that longan is obeyed strong soul for a long time, and it is not old to make light of one's life by commiting suicide.The traditional Chinese medical science thinks that longan has the effect of " being better than genseng ".Modern science is discovered longan except that containing a large amount of glucose, fructose and sucrose, also contains abundant polysaccharide, but is not much accounted of and big quantity research always.
The value of the mensuration of relevant longan chemical ingredients, the characteristics of pharmacological action, health nutrient had some reports in recent years, but did not then appear in the newspapers as yet for the extracting method and the technology of longan polysaccharide.
The purpose of this invention is to provide a kind of longan polysaccharide that scientifically extracts, and can keep the activity of longan polysaccharide and the local flavor of former longan, improve the technology of the extraction yield of longan polysaccharide to greatest extent.
These purposes of the present invention and other purposes will further be set forth and illustrate by following detailed description.
Longan polysaccharide extracting process of the present invention comprises steps such as degreasing, double-enzyme hydrolysis, flooding, alcohol precipitation and drying and crushing.
Further, longan polysaccharide extracting process of the present invention comprises following concrete steps:
A, defatting step: will shell longan or dried longan are pulverized, and add 1.5～3.0 liter alcohol by 1 kilogram of shell longan or dried longan, 50～80 ℃ of backflow lixiviates 0.6～1.5 hour, or soak at room temperature 3～6 hours, solid collected by filtration thing, water flushing 1～2 time.
B, double-enzyme hydrolysis step: above-mentioned solids is added water 1.5～3.0 liters, use acid to transfer pH value to 1.8～3.0, press the per kilogram raw material and add 4～15 gram stomach en-s, in 30～40 ℃ of insulations, stirring 3～5 hours; Adding alkali accent pH value then is 7～9, presses the per kilogram raw material and adds 4～15 gram trypsinase, in 30～40 ℃ of insulations, stirring 3～5 hours, adds acid accent pH value then for acid.
C, flooding step: above-mentioned raw materials is added 1～5 liter water again, put pressure kettle, or in 100 ℃ of lixiviates 2～4 hours, filter and remove slag and insolubles, the filtrate neutralization in 105～115 ℃ of lixiviates 0.5～1.5 hour.
D, alcohol precipitation step: above-mentioned vat liquor is concentrated into half of former cumulative volume at 30～70 ℃, and adding medical alcohol is 50～70% to ethanol concn, and placement is spent the night, and leaches throw out, centrifuge dripping, the longan polysaccharide solids that must wet.
E, drying and crushing step: with above-mentioned wet solids, evenly spread and place drip pan,, dried 2～8 hours at 60～80 ℃, pulverize light grey longan polysaccharide finished product; Or adopt with above-mentioned wet solids centrifuge dripping, wash, drying under reduced pressure, drying pressure is 20～200Pa, the time is 5～8 hours, pulverize light grey longan polysaccharide finished product.
In the present invention, the water that is adopted is deionized water, distilled water, pure water and contains one of mineral ion water.
The longan polysaccharide that the present invention extracts is light gray-light salmon, and nothing is smelt, and water soluble is a kind of dextran that is similar to lentinan, tentatively is defined as beta-glucan, finds out to have typical dextran feature from infrared spectra.
The present invention adopts Composite Double zymotechnic and dry extraction novel process can greatly improve the activity and the immunity of longan extract, keeps longan effective constituent and original color, smell and taste, has improved the extraction yield of longan polysaccharide to greatest extent.
The product of preparing with method of the present invention has very high biological activity and immunity, and rich in proteins, phosphorus, choline, trace element, is present known intelligence development, brain tonic, anti-ageing, bushing is promoted blood circulation, relieving restlessness is dispelled dry, eyeshield eyesight-improving health care function treasure.
In the present invention, all raw material, half products all can be buied from market.
As non-refering in particular to, all parts, amount are the weight unit of gross weight for the basis in the present invention.
Below further specify the present invention by specific embodiment, but embodiment only be used for the explanation can not limit the scope of the invention.
