Description

A kind of lotus root full-powder and preparation method thereof

Technical field

The present invention relates to a kind of food prepared with Rhizoma Nelumbinis and preparation method thereof, particularly a kind of lotus root full-powder and preparation method thereof for raw material.

Background technology

Rhizoma Nelumbinis has another name called Rhizoma Nelumbinis, Rhizoma Nelumbinis belongs to nymphaeaceae plant, and Rhizoma Nelumbinis is the subterraneous stem of lotus, micro-sweet and crisp, the most tasty and the most refreshing, can eat raw and also can cook, and has higher medical value.The Amylum Nelumbinis Rhizomatis made with Rhizoma Nelumbinis is a kind of Traditional health care instant food of China, Amylum Nelumbinis Rhizomatis can preserve the mass efficient composition in Rhizoma Nelumbinis, simply eaten convenience, brews i.e. edible through boiled water, Amylum Nelumbinis Rhizomatis through reconstituting, crystal clear, suffuses an exquisite fragrance all around, pure and fresh good to eat, delicious flavour, all-ages, can not only allay one's hunger, or tonic good merchantable brand.Traditional Amylum Nelumbinis Rhizomatis processing method is that fresh Rhizoma Nelumbinis is cleaned, defibrination, separate, filter, be dehydrated, dry, and during separating and filtering, will filter off a part of Rhizoma Nelumbinis dregs, and it is all dietary fiber that this part Rhizoma Nelumbinis dregs removes Rhizoma Nelumbinis skin major part.Dietary fiber is that health diet is indispensable, and dietary fiber is keeping playing the part of in digestive system health necessary role, absorbs enough fibers simultaneously and can also prevent cardiovascular disease, cancer, diabetes and Other diseases.Dietary fiber can clean wall of digestive and strengthen digestive function, simultaneously can dilute and add removing of the carcinogen in food and noxious substance, the digestive tract that protection is fragile, prevent colon cancer.Fiber can slow down digestion rate and rapid drainage cholesterol, and the blood glucose in blood and cholesterol can be made to control in preferable level.And the Rhizoma Nelumbinis dregs produced when producing Amylum Nelumbinis Rhizomatis is as being difficult to get fat for hello domestic animal, it is typically only capable to as producing garbage disposal, it is easy to cause environmental pollution.

Summary of the invention

It is an object of the invention to provide the technical scheme of a kind of lotus root full-powder and preparation method thereof.The present invention is to preserve the content of the nutrient substance such as dietary fiber in fresh Rhizoma Nelumbinis on the basis of not changing tradition Amylum Nelumbinis Rhizomatis mouthfeel, color and luster and local flavor to greatest extent.

The preparation method of lotus root full-powder of the present invention is:

(1) select that surface color is pure white, outward appearance finishing, the fresh Rhizoma Nelumbinis of non-rot maturation are raw material；

(2) clean up surface silt, with temperature be 80-100 DEG C, concentration be that the sodium hydroxide solution of 8%-12% soaks 2-5 minute, taking-up clear water rinses, epidermis natural removal；Can also remove the peel with stainless steel knife；

(3) the length direction crosscutting one-tenth thickness along Rhizoma Nelumbinis is the Rhizoma Nelumbinis slice of 2-5cm；

(4) soaking 4-8h during Rhizoma Nelumbinis slice puts into colour fixative, after taking-up, clear water rinses, and described colour fixative is containing 0.05%-0.15%Na₂S₂O₅, 0.2%-0.4%Cacl₂Aqueous solution；

(5) put into blanch 2-6min in boiling water, take out airing moisture；

(6) 60-75 DEG C of dry 5-10h, to moisture≤14%；

(7) dried lotus root is crushed to more than 200-250, for full Amylum Nelumbinis Rhizomatis.

The lotus root full-powder of the present invention is the lotus root full-powder prepared by said method.

Rhizoma Nelumbinis rich in starch, minerals and vitamins C.In every hectogram Rhizoma Nelumbinis, containing 1 gram of protein, 0.1 gram of fat, carbohydrate 19.8 grams, dietary fiber 0.7 gram, calcium 19 milligrams, 51 milligrams of phosphorus, ferrum 0.5 milligram, carotene 0.02 milligram, vitamin B 011 milligram, vitamin B2 0.04 milligram, vitamin C 25 milligrams and the nutritional labeling such as tannic acid, asparagine.Rhizoma Nelumbinis meat easily digests, suitable old and young nourishing.Rhizoma Nelumbinis also has medical value, and the traditional Chinese medical science is thought, raw Rhizoma Nelumbinis is sweet, cold, nontoxic.Ripe Rhizoma Nelumbinis is sweet, temperature, the most nontoxic.Shennong's Herbal and Compendium of Material Medica have the highest evaluation to Rhizoma Nelumbinis.Shennong's Herbal has the record of " Rhizoma Nelumbinis reality stem ", and ancients think, Rhizoma Nelumbinis hole key is exquisite, hidden in silk synthetic fibre, can treat blood and quench the thirst, and reinforcing the heart strengthening the spleen can be rated as good medicine.Raw Rhizoma Nelumbinis is cold in nature, has repercussive heat clearing away, and relieving restlessness is quenched one's thirst, to nose bleeding, hematuria, have blood in stool, metrorrhagia etc. has anastalsis, reduces phlegm, control pneumonia, pulmonary tuberculosis, enteritis, insufficiency of the spleen drop, all diseases such as metrorrhagia；Ripe Rhizoma Nelumbinis is warm in nature, has reinforcing the heart hemopoietic, nourishes strong and effect of strengthening the spleen and stomach.Rhizoma Nelumbinis is clean like beautiful, Bai Ruxue, and it has strong vital essence, thick intestinal taste, nourishing YIN and moistening the lung, removes the unique effects such as cold heat radiation.In tubers food, Rhizoma Nelumbinis iron-holder is higher, therefore the most suitable to the patient of iron deficiency anemia；The sugar content of Rhizoma Nelumbinis is the highest, contain again substantial amounts of vitamin C and abundant be dietary fiber, the people for diseases cutting with weakness such as hepatopathy, constipation, diabetes is the most highly beneficial；Containing abundant vitamin K in Rhizoma Nelumbinis, there is convergence blood vessel and the effect of hemostasis, the most suitable for congestion, haematemesis, epistaxis, hematuria, the people having blood in stool and puerpera.

First the present invention holds raw material closes, and selects that surface color is pure white, outward appearance finishing, the fresh Rhizoma Nelumbinis of non-rot maturation are raw material, is preferably selected the high Rhizoma Nelumbinis of content of starch and produces Amylum Nelumbinis Rhizomatis.Containing tanning matter in the skin on Rhizoma Nelumbinis top layer, not only easily variable color, also can produce astringent taste, and the skin on Rhizoma Nelumbinis surface is removed by the present invention, and the method for peeling is chemical peeling method and method of either manually or mechanically peeling, and both approaches all can make active ingredient loss reduction in Rhizoma Nelumbinis.Owing to Rhizoma Nelumbinis peeling rear surface is easily oxidized to atropurpureus with air contact, affect product colour, so the present invention carries out color retention in time to raw material, it is ensured that the color of finished product.Enzyme in Rhizoma Nelumbinis will make the Rhizoma Nelumbinis generation brown stain in processing, the present invention that raw material is put into blanch in boiling water to carry out enzyme denaturing process.Although dietary fiber has good health-care effect to health, but mouthfeel is poor, chews as wood slag, uses micronizing method that Amylum Nelumbinis Rhizomatis is crushed to more than 200-250 mesh, make mouthfeel be greatly improved in the present invention.Making, with Rhizoma Nelumbinis, the mass efficient composition that Amylum Nelumbinis Rhizomatis can preserve in Rhizoma Nelumbinis, the present invention is to try to many dietary fibers retained in Rhizoma Nelumbinis compared with tradition essence Amylum Nelumbinis Rhizomatis, and the nutrition making Amylum Nelumbinis Rhizomatis is more comprehensive.The present invention changes the processing technique of tradition Rhizoma Nelumbinis starch, decreases the waste of separating and filtering Rhizoma Nelumbinis dregs, remains whole fibrous matters of Rhizoma Nelumbinis, to meet modern's demand to dietary fiber, makes up essence starch deficiency in terms of nutritional labeling.The amount of waste producing Amylum Nelumbinis Rhizomatis, by sufficiently effective for Rhizoma Nelumbinis dregs utilization, can be preferably minimized, also be to be preferably minimized by the contaminant capacity of environment, so by effectively reducing enterprise's input in terms of environmental protection, reduce enterprise operation cost by the present invention.The present invention is a kind of novel, all-ages to facilitate health food.
