Description
Technical field
The present invention relates to starch food fields, and in particular to a kind of preparation method of fern powder.
Background technique
Fiddlehead is to be grown in a kind of wild pteridophyte class plant on hillside, and be described as " mountain dish king ", and fern rhizome is starch-containing
The rhizome of 35%-46%, fiddlehead can prepare fern powder by processing, and Compendium of Material Medica carries: " its root purple, it is intradermal to have white powder, it smashes
Rotten, wash repeatedly clear, take powder to make cabinet viscous, swing skin as line and eat it, color is pale purple and very sliding U.S.A ", fern powder can vermicelli processed, bean sheet jelly, preparation
Cake dessert can also replace bean powder, lotus root starch, nutritive value very abundant.
Currently, traditional handicraft is: fresh rhizome being removed feeler, dead leaf is extractd, is eluted with water, the fern root after cleaning is used
Pulverizer or stone, which are ground, to be crushed, and is continued to grind after water is added, then use Bag filter, is added water to filter repeatedly filter residue, up to not white
Until color powder and mucus, then gained filtrate is refiltered once with cloth bag, puts precipitating in people's precipitation vessel, removed after precipitating
Surface clear water, is filtered dry with cloth bag, fern powder.
Summary of the invention
Using conventional method, the fern powder rate of recovery is not high, and due to containing a large amount of pectin in fern root, pectin viscosity is big, unfavorable
In the leaching of starch, the fern powder rate of recovery is influenced.
It is high that problem to be solved by this invention is just to provide a kind of fern powder rate of recovery, and step is simply fainted powder, preparation method thereof,
The invention adopts the following technical scheme:
S1, raw material crush: fresh fern root being removed feeler, is eluted with water, is then cut into the fern less than 0.5cm thickness
Root thin slice crushes fern root thin slice in pulverizer；
S2, defibrination: the fern root and clear water of crushing being mixed and are sent into starch machine slurry, obtain fern root slurry；
S3, alkali cleaning: fern root slurry is poured into stirring container, sodium bicarbonate solution is added, and constantly stir, makes bicarbonate
Sodium is sufficiently reacted with the pectin in fern root；
S4, filtering: the solution after above-mentioned reaction is filtered through filter, obtains initial filtrate, collects initial filtrate and filter residue；
S5, secondary alkali cleaning: above-mentioned filter residue is mixed again with the clear water of 1-2 times of quality, obtains secondary mixed liquor, and add carbon
Sour hydrogen sodium solution, continuous stirring sufficiently reaction；
S6, secondary filter: the solution after step 5 reaction is filtered through filter, obtains secondary filtrate；
S7, sedimentation separation: initial filtrate is mixed with secondary filtrate, is separated with centrifugation seperator to get primary wet
Starch；
S8, purification: primary wet starch addition clear water being mixed, after stirring evenly, is filtered through filter, collects filtrate, filtrate warp
The separation of centrifugation seperator, obtains purification wet starch；
S9, drying: purification wet starch is drying to obtain finished product.
It is preferential, in the step S1, the fern root thin slice be cut into a thickness of 0.2-0.5cm.
Preferential, in the step S2, the fern root of the chopping is that 1:2-1:3 is mixed according to mass ratio with clear water.
Preferential, in the step S3, the mass fraction of the sodium bicarbonate solution is 5-10%；The bicarbonate
The mass ratio 1:100-1:50 of sodium solution and fern root slurry；The reaction time is 1-2h.
Preferential, in the step S4, the filter cloth of the filter arrangement 50-100 mesh.
