Abstract
The invention belongs to the technical field of food processing and in particular relates to a method for extracting fern root starch. The method for extracting the fern root starch comprises the following steps of: a, pulping the fern root; b, filtering out fern root starch liquid from the fern root pulp, and precipitating and separating the obtained fern root starch turbidity liquid to obtain fern root wet starch; and c, crushing and drying the fern root wet starch. The technical scheme has the following advantages that: by the method for extracting the fern root starch, fresh fern root is pulped, filtered repeatedly, precipitated to obtain the fern root starch, so that extraction rate is over 7 percent, nutrient elements of the fresh fern root are retained; edible deadline is prolonged; the fern root starch is convenient to store and eat; and market and people living requirements are met.
Description
Technical field
The invention belongs to food processing technology field, relate in particular to a kind of extracting method of fern root starch.
Background technology
Along with the raising day by day of living standard, people are also more and more higher to the requirement of the natural sex of food, nonstaining property, green.Fiddlehead is that a kind of distribution is wide, and traditional hill dish that output is high is known as " king of hill dish ", because of its unique nutritive value, by the catering industry extensive use, by consumers in general are favored.The Cyclosorus herbaceos perennial, be rich in trace elements such as the nutritional labeling of multiple needed by human body such as abundant vitamin C, radish element, protein, sugar and mineral matter potassium, iron, calcium, phosphorus, also contain rare short decortication (tannin composition), have anticancer, heat-clearing, fat-reducing, analgesic, separate effects such as urine, and viruses such as influenza, encephalitis B are had the obvious suppression effect.Pterosin in the fern root has certain inhibitory action to bacterium, can be clearing heat and detoxicating, and bactericidal antiphlogistic.Some active ingredient of fern root can hemangiectasis, brings high blood pressure down, and the fern root can also the antidiarrheal diuresis, and contained dietary fiber can promote gastrointestinal peristalsis, can detoxicating intestine, have the effect of therapeutic method to keep the adverse qi flowing downward defaecation.Fiddlehead commonly used among the people is treated dysentery and urinates dripping obstructed.Normal food Neng Bu Bi benefit gas, strong muscule increases resistance against diseases.But its main deficiency is a fresh vegetable, and the edible phase is short, at present, also can't process to prolong its edible phase fiddlehead, can not satisfy market and people's living needs.
Summary of the invention
The invention provides a kind of extracting method of fern root starch, be intended to solve at present, can't process to prolong the problem of its edible phase fiddlehead because the edible phase of fern root fresh vegetable is short.
The present invention is achieved in that a kind of extracting method of fern root starch, comprising:
Step a: the fern root is pulled an oar;
Step b: the fern root starch fluid in the fern root slurry is filtered, and the turbid liquid precipitate of fern root starch that filtration is obtained separates, and obtains fern root wet starch;
Step c: fern root wet starch is pulverized dry.
Technical scheme of the present invention also comprises: in described step a, the mode of described making beating can be pulled an oar by beater, also can pull an oar by other modes.
Technical scheme of the present invention also comprises: described step a also comprises: fern root slurry is added clear water washing and continuous the stirring, fern root starch fully is suspended in the water, and the root slag is separated.
Technical scheme of the present invention also comprises: described step b also comprises: make filter the turbid liquid natural subsidence of starch, and the supernatant water after the sedimentation of inclining obtains elementary fern root wet starch.
Technical scheme of the present invention also comprises: in described step b: the filter cloth of described filtration is 200 orders.
Technical scheme of the present invention also comprises: also comprise among the described step b: filter by filter once more after elementary fern root wet starch is stirred evenly with the clear water rinsing.
Technical scheme of the present invention also comprises: also comprise among the described step b: the turbid liquid of fern root starch that filtration is obtained is precipitate and separate once more, obtains exquisite fern root wet starch.
Technical scheme of the present invention also comprises: in described step b: the filter cloth of described filtration is 300 orders.
Technical scheme of the present invention also comprises: in described step b: the method for described filtration also can be filtered by other modes for filtering by filter.
Technical scheme of the present invention has following advantage or beneficial effect: the extracting method of fern root starch of the present invention by with the making beating of fresh fern root, filter repeatedly, post precipitation obtains fern root starch, make more than the extraction rate reached to 7%, the nutrient that has kept fresh fern root, simultaneously prolonged the edible time limit again, and be convenient to preserve, edible convenient.
Description of drawings
Accompanying drawing 1 is the schematic flow sheet of the extracting method of fern root starch of the present invention.
The specific embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
Seeing also Fig. 1, is the schematic flow sheet of the extracting method of fern root starch of the present invention.The extracting method of fern root starch of the present invention may further comprise the steps:
Step 10: the fern root is pulled an oar;
Wherein, the mode of making beating can be pulled an oar by beater, also can pull an oar by other modes.
Step 20: fern root slurry is added clear water washing and continuous the stirring, fern root starch fully is suspended in the water, and the root slag is separated;
Step 30: fern root starch fluid is filtered by filter;
In this step, the filter cloth of filtration is 200 orders, also can filter by other modes.
Step 40: make filter the turbid liquid natural subsidence of starch, and the supernatant water after the sedimentation of inclining obtains elementary fern root wet starch;
In this step, the turbid liquid of starch can be placed settling tank (bucket) or other containers, wait for certain hour, the starch of suspension can be precipitated fully.
Step 50: filter by filter once more after elementary fern root wet starch stirred evenly with the clear water rinsing;
In this step, the filter cloth of filtration is 300 orders.
Step 60: the turbid liquid of fern root starch that filtration is obtained is precipitate and separate once more, obtains exquisite fern root wet starch;
Step 70: exquisite fern root wet starch is pulverized dry;
Step 80: finish the extraction of fern root starch.
The extracting method of fern root starch of the present invention by with the making beating of fresh fern root, filter repeatedly, post precipitation obtains fern root starch, make more than the extraction rate reached to 7%, the nutrient that has kept fresh fern root, simultaneously can prolong the edible time limit again, and be convenient to preserve, edible convenient, satisfied market and people's living needs.
The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
