Description

A kind of nanometer selenizing Concha Ostreae polysaccharide solid beverage
Technical field
The invention belongs to solid beverage field, be specifically related to a kind of nanometer selenizing Concha Ostreae polysaccharide solid beverage product.
Background technology
Concha Ostreae has another name called oysters, oyster, is distributed in each ocean in temperate zone and the torrid zone stretch of coastal water, is the first big cultivated shellfish, one of big cultivated shellfish of Ye Shi China four in the world.Concha Ostreae is the marine food of a kind of comprehensive nutrition, internal containing nutrients such as abundant glycogen, protein, minerals and vitamins, has the non-nutritive element of different physiological roles possibly together with taurine, ornithine etc..Vitamin contained in Concha Ostreae and the kind of mineral are the most complete, including vitamin A, B, C, D, E, H etc. and calcium, selenium, phosphorus, ferrum, zinc etc., wherein vitamin B group, zinc, Se content are the abundantest, and this is that Concha Ostreae provides huge feasibility as nutraceutical, functional food, the raw material of drug development.
Concha Ostreae polysaccharide is by the homopolysaccharide of glucose polymerisation, and its structure is complicated, and relative molecular mass is between millions of to tens million of.Concha Ostreae polysaccharide has good biological activity, has obvious preventing and treating cardiovascular disease function, also has blood fat reducing, anticoagulation, the activity of raising body's immunity.Japanese Scientists also finds that Concha Ostreae polysaccharide can promote that Skin Cell regenerates, and alleviates the functions such as the damage that skin causes by ultraviolet.
Nanometer selenium is as a kind of existence form of selenium element, it is possible to directly remove interior free yl, and bio-toxicity is low, can be absorbed rapidly by organism.But, nanometer selenium is easily reunited so that it is non-oxidizability and anti-tumor activity are gradually lowered along with the increase of particle diameter, this greatly limits nanometer selenium in health food and the application of field of medicaments.
Summary of the invention
It is an object of the invention to provide a kind of nanometer selenizing Concha Ostreae polysaccharide solid beverage, thus provide a kind of good stability, preparation method simple nanometer selenium product, to make up the deficiency of existing nanometer selenium supplementing preparation.
A kind of nanometer selenizing Concha Ostreae polysaccharide solid beverage, it is characterised in that described solid beverage is to be prepared with following steps:
1) extraction of Concha Ostreae polysaccharide: take fresh Carnis ostreae and clean up, stir evenly with refiner making beating, then hot water extraction is carried out, by centrifugal for lixiviating solution except precipitation, cryoconcentration, then according to certain proportioning adds the ethanol of the 95% of appropriate volume in concentrated solution, it is centrifuged off supernatant and i.e. obtains Concha Ostreae polysaccharide;
2) dialysis treatment: the Concha Ostreae polysaccharide distilled water obtained in step 1) is dissolved again, putting into molecular weight interception is in 8000 daltonian bag filters, with the distilled water dialysis 24h of flowing, then dialyse 24h with ultra-pure water, then by the Concha Ostreae polysaccharide solution cryoconcentration after dialysis;
3) selenization: with step 2) in the Concha Ostreae polysaccharide that obtains as template, add a certain proportion of sodium selenite solution and Vc solution, water-bath 30min, carry out nanometer selenization;
4) it is dried: by the nanometer selenizing Concha Ostreae polysaccharide solution cryoconcentration in step 3), then carry out lyophilization or low temperature spray drying;
5) packaging: dried Concha Ostreae polysaccharide powder is carried out vacuum packaging and is nanometer selenizing Concha Ostreae polysaccharide solid beverage.
Preferably, it is 30mL/g-50ml/g that Concha Ostreae polysaccharide extraction conditions controls liquid ratio, Extracting temperature 50 DEG C-60 DEG C, extraction time 3h-6h.
Preferably, the condition of selenization is final concentration of 200 mg/L-400mg/L, the Vc of Concha Ostreae polysaccharide and the mol ratio of sodium selenite is 3:1.
The structure of Concha Ostreae polysaccharide is complicated, has abundant glycosidic bond, monosaccharide residue and link position, it is possible to form different space conformations, is a kind of preferably nanometer selenium size control agent.The present invention is combined with nanometer selenium and the respective feature of Concha Ostreae polysaccharide and advantage, carrys out constructing function nanometer selenium with Concha Ostreae polysaccharide for biological template adjusting control agent, alleviates the reuniting effect of nanoparticle, enhances the biological activity of nanometer selenium and Concha Ostreae polysaccharide.
Accompanying drawing explanation
Fig. 1: the scanning electron microscope (SEM) photograph of nanometer selenizing Concha Ostreae polysaccharide.
Fig. 2: the transmission electron microscope picture of nanometer selenizing Concha Ostreae polysaccharide.
Nanometer selenizing Concha Ostreae polysaccharide prepared by the present invention, nanometer selenium diameter is at about 50nm, and these nano granules of selenium are combined in (Fig. 1) on Concha Ostreae polysaccharide skeleton by physical absorption.Nanometer selenium surface is without covering, and size is consistent, and be evenly distributed (Fig. 2).The nanometer selenizing Concha Ostreae polysaccharide of the present invention has certain antioxidant activity in vitro.When the concentration of nanometer selenizing Concha Ostreae polysaccharide is 56mg/L, 32mg/L and 320mg/L, the Scavenging activity of hydroxyl radical free radical, DPPH free radical and superoxide radical is respectively 32.7%, 94.7% and 21.7%.The nanometer selenizing Concha Ostreae polysaccharide solid beverage that the present invention produces, polyoses content is 7.67%, has reached the purpose of polysaccharide enrichment, good stability, has good organoleptic quality and local flavor, meets solid beverage relevant criterion.
