The industrialization extraction and separation method of ganoderma spore polysaccharide and tripping device
Technical field
The invention belongs to edible mushrooms deep process technology field, be specifically related to a kind of industrialization extraction and separation method of ganoderma spore polysaccharide.
Background technology
Glossy ganoderma (Ganodermalucidum) is polyporaceae Ganoderma fungi, containing abundant nutritive substance, in the edible history that folks of china has source far away, be a kind of there is invigorating the spleen and replenishing QI, the valuable ingredient of traditional Chinese medicine of effect of strengthening the body resistance to consolidate the constitution.Ganoderma spore is the glossy ganoderma growth and maturity phase, to be hit by a bullet the extremely small avette sexual cell shot out from glossy ganoderma lamella, ovalize, average 8 μm of minor axis, average 11 μm of major diameter.Modern scientific research shows, Ganoderma spore has stronger physiologically active than Ganoderma sporophore, what wherein play a major role is ganoderma spore polysaccharide, and it has multiple biological activity, as Tumor suppression, improves immunity of organisms, raising body's hypoxia tolerance, elimination free radical etc.
But when furtheing investigate the biological activity of Ganoderma spore, when finding with water extraction ganoderma spore polysaccharide, it is the thorny difficult problem of part that spore granulated slag in aqueous extract filters removing.Because the particle diameter of Ganoderma spore is small, on average only have about 10 μm, the highdensity filter screen of 600 object it also can be through, although the higher thinner filter screen of density is through few, but filtration velocity slowly, be only applicable to a small amount of laboratory and use, be difficult to realize industrialization.
The conventional treatment method of current industrialization is, extracting solution adopts stratification, siphon supernatant liquor, 400-500 order filter cloth " excessively sieve method " only can remove the Ganoderma spore granulated slag of 60-70%.Because the density of extracting solution miospore granulated slag is close with supernatant liquor, sedimentation is very slow, usually hold over night is needed, but still supernatant liquor and spore granulated slag effectively can't be separated, supernatant liquor accounts for cumulative volume ratio only 60%, and the very long settling time, Ganoderma spore water suction fermentation generation also can be caused to become sour, lose utility value.Because ordinary method is consuming time oversize, operating process is loaded down with trivial details, and usually only extract once, extraction yield is approximately 62%, and the utilization ratio of extraction yield low-resource is also low.Length consuming time, complex operation, is difficult to realize industrialization and produces, become the bottleneck that ganoderma spore polysaccharide industrialization development utilizes.
In existing public technology, patent CN101703531B " a kind of vacuum freezedrying of Ganoderma spore powder and the method for purification ", adopt 80-500 object silk, cotton, gauze or stainless steel sift to filter, filtrate carries out press filtration with the air pressure filter of 1-30 μm of aperture filter membrane again.The method needs constantly to change cleaning filter cloth, not can be automated operation, and labour intensity is large, and filter membrane consumptive material is many, a Suitable assays room lab scale.Patent CN102766593A " a kind of method of purification of Ganoderma spore ", by after spiral separator by Ganoderma spore powder mixed solution, with being greater than 300 object strainer filterings, filtrate reinstalls powder filtering bag, gone out by hydraulic pressure in powder filtering bag by air compressor machine, because powder filtering bag is easily blocked, not only process is complicated also to need constantly to clean or change the method, can not automated operation, be difficult to realize industrialization and produce.
If adopt traditional plate-and-frame filter press to be separated, because the spore granulated slag viscosity in aqueous extract is high, quality is soft, along with the carrying out of filtering, be gathered in gradually on filter cloth, cause filter cloth to block, filtration velocity slows down, growth consuming time (about 10-12hr) and change filter cloth loaded down with trivial details, therefore this method is also infeasible.Someone adopts tubular-bowl centrifuge to be separated; because in Ganoderma spore powder water extraction suspension, solid content is higher; tubular-bowl centrifuge rotary drum volume is little; after material enters rotary drum; be deposited on rotary drum in a large number in short period of time; need frequent shutdown to dismantle rotary drum to remove the gred, add the complicacy of operation, affect production efficiency.In addition, precipitate more sticky, more difficult during cleaning.Therefore, tubular-bowl centrifuge processing power and level of automation are all poor.
