(2) alkaline purification: will the alkali of the red algae after dish mixed solution alkaline purification 10-24 hour at 50 DEG C be washed;
(3) wash: the red algae tap water after alkaline purification being carried out flushing, to be dipped to pH value be neutral, is 6 with 0.05-0.3% hydrochloric acid adjust pH;
(4) pre-treatment: by the red algae after washing, be crushed to 5 mm in sizes, add in hot water and be preheated to 50 ± 2 DEG C, after 10-15 minute, defibrination;
(5) enzymolysis: add compound enzymic preparation, its addition is 3 ‰-7 ‰ of described red algae Mao Caichong, keeps temperature to be 55 DEG C-60 DEG C, enzymolysis 0.5-1h, Keep agitation; Heat up glue 70-80 DEG C the enzyme 5-10 minute that goes out;
(6) extract: the hot water of 60-90 DEG C of the red algae after enzymolysis is boiled glue 1 hour, boils in glue process and will constantly stir;
(7) Plate Filtration: by well-done thick glue filtered while hot, in filtered filtration residue, gel content is lower than 0.5%;
(8) potassium: the glue after to be filtered is cooled to 30-35 DEG C, slowly adds flocculation sediment in glue by the Klorvess Liquid of 5-6%, static 30 points of clock agings after flocculation sediment is complete;
(9) filter-press dehydration: the red seaweed polysaccharide throw out plate-and-frame filter press after potassiumization is complete dewaters, and makes the water content of blob of viscose at 65-85%;
(10) pulverize: red seaweed polysaccharide blob of viscose after filter-press dehydration is pulverized wind and delivers to baking operation;
(11) dry: the red seaweed polysaccharide after pulverizing is delivered to baker, dries at about 70 DEG C, red seaweed polysaccharide moisture≤12% after drying.
Preferably, described red algae comprises Eucheuma muricatum (Gmel.) Web． Van Bos．, carrageen, China fir algae.
Preferably, the alkali mixed solution described in step 2 is the mixed solution of the Repone K of 6-8% sodium hydroxide and 5-7%.
Wherein, the compound enzymic preparation described in step 5 forms according to following weight percent, proteolytic enzyme 40-50%, cellulase 30-40%, polygalacturonase 10-30%.
The invention has the beneficial effects as follows:
1, pretreatment process is increased, General Promotion enzymolysis efficiency and speed.
Eucheuma muricatum (Gmel.) Web． Van Bos．, carrageen, China fir algae are pulverized, raw material is crushed to less particle, then by defibrination after being heated to 50 DEG C, now raw material particle size is less, considerably increases the contact area of raw material and enzyme, thus General Promotion enzymolysis efficiency and speed, reduce the usage quantity of enzyme, reduce product cost.
2, adopt compound enzymic preparation to carry out enzymolysis, efficiency is high, and action time is short, and extraction yield is high
The compound enzymic preparation adopting cellulase, proteolytic enzyme and polygalacturonase to mix carries out enzymolysis, enzymolysis strengthens, only cellulase successful was used comparatively, cell walls crushing effect is thorough, more be conducive to the stripping of glue, increase extraction yield, the extraction yield of red seaweed polysaccharide can improve 2-3%, realizes the Second Revolution of marine alga processing.
3, filter-press dehydration reduces blob of viscose moisture, realizes energy-saving and emission-reduction.
In filter-press dehydration operation, the moisture of blob of viscose is down to 65-85%, abandons dehydration of alcohol, reduce environmental pollution, reduce steam usage quantity, realize energy-saving and emission-reduction, also greatly reduce product cost.
