Description
Technical field
The present invention relates to derive from the preparation of the starch of plant, especially a kind of method of producing pueraria starch from the root of kudzu vine.
Background technology
We know, the root of kudzu vine (Lobed Kudzuvine Root) is the piece root of vine elegant jessamine, and rich in starch and Flavonoid substances in the root of kudzu vine (being Daidzin, xylopuerarin, puerarin) have very high edibleness and medicines and health protection to be worth.It is edible and medicinal plant that China Ministry of Health was published as in 1988, and cultivated area development is in recent years very fast.
The root of kudzu vine is the subterranean organ of Pueraria lobota, more flourishing, is main storage organ, rich in starch, and cell is large, is Polygons, and without intercellular space, xylon is few compared with phloem fiber.Pueraria starch, by extracting from the root of kudzu vine, has certain health-care effect because the pueraria starch extracting contains Vitamin P complex.In recent years, pueraria starch is as the batching of food, part or replacing whole hydrophilic colloid in numerous food, the high-grade nutrient dietetic food that is processed to various cakes, cold drink, bean vermicelli and keeps fit nourishing.Its traditional extraction technique is generally through cleaning, pulverize defibrination, screening (filter, centrifugal or precipitation), dehydration, the operation such as dry.This traditional pueraria starch extraction process exists that preparation cycle is long, starch extraction rate is low, pigment is adsorbed on starch and cause the deficiency that whiteness is low.
Summary of the invention
For overcome in prior art pueraria starch extract exist that preparation cycle is long, extraction yield is low, absorption has pigment and the low deficiency of whiteness the invention provides a kind of method of producing pueraria starch from the root of kudzu vine that technique is reasonable, easy and simple to handle, with short production cycle, the extraction yield of product is high on starch.
The technical solution adopted for the present invention to solve the technical problems is: a kind of method of producing pueraria starch from the root of kudzu vine, is characterized in that: process following process steps:
A, raw material are chosen with processing and are chosen smooth surface, the unabroken root of kudzu vine is raw material, with clear water, rinse, and remove surperficial impurity;
The root of kudzu vine after b, defibrination clean step (a) is sent in paste roller mill, adds root of kudzu vine quality 2-5 water doubly, and defibrination, obtains root of kudzu vine slurry mixture;
C, enzymolysis are heated to 35-45 ℃ by the resulting root of kudzu vine slurry mixture of step (b), and regulating pH value is 6.0～7.0, adds the cellulase of root of kudzu vine quality 0.2%～0.5% to carry out enzymolysis, and enzymolysis time is 1～3h; After enzymolysis completes, regulate pH value to 5.5～6.0, be warming up to 45～55 ℃; The polygalacturonase that adds root of kudzu vine quality 0.5%～1%, enzymolysis 1～2h, obtains root of kudzu vine enzymolysis mixed solution;
D, filtration by 90～120 object filter clothes, are collected the resulting root of kudzu vine enzymolysis of step (c) mixed solution filter residue and are added clear water, stir, then filter by filter cloth; By aforesaid operations, carry out filter 23～4 time again; Merge filtered solution, obtain starch solution;
E, precipitate and separate staticly settle 48～72h by the resulting starch solution of step (d), carry out starch separated with water; Get bottom settlings, obtain starch sedimentation;
It is 40～50% that f, bleaching add water adjustment concentration by the resulting starch sedimentation of step (e), and regulating pH value is 5～7, adds hydrogen peroxide to final concentration 2～4%, stirs, and controls 35～45 ℃ of temperature, bleaching 0.5～1h; Filter, obtain wet starch;
G, dry the resulting wet starch of step (f) is sent into Vacuumdrier, control vacuum tightness-0.09～0.03 kpa in drying machine, 35～60 ℃ of temperature, carry out vacuum dehydrating at lower temperature, obtain kudzuvine root starch finished product.
The present invention is that to choose the root of kudzu vine of high-quality be raw material, adds water mill slurry and process after cleaning, and obtains root of kudzu vine slurry mixture; Root of kudzu vine slurry mixture adds cellulase, polygalacturonase successively, and control condition is carried out enzymolysis; Enzymolysis mixed solution, through filter-cloth filtering, precipitates, and separation, gets starch sedimentation and add hydrogen peroxide, and control condition is carried out bleaching; Filter, obtain wet starch; Vacuum dehydrating at lower temperature, obtains kudzuvine root starch finished product.The present invention adds cellulase to carry out enzymolysis to root of kudzu vine slurry mixture, makes Mierocrystalline cellulose fast degradation, fully cracks cell walls, promotes the stripping of starch, then adds the pectin in the pectinase enzymatic hydrolysis root of kudzu vine, makes more starch free out; The present invention adopts hydrogen peroxide to carry out bleaching to starch solution, and its bleaching effect is good, and condition is easily controlled, residual few.Technique of the present invention is reasonable, easy and simple to handle, with short production cycle, the extraction yield of environmentally safe, product is high.Through measuring: adopt preparation method provided by the present invention, its pueraria starch extraction rate reached is more than 93%.
