Abstract
This method is to wash under heating the screened and smashed raw-material of plant mass in an appropriate meutral washing liquid to remove components of sugar, protein, fat, tannin, pigment and wax, then to remove its starch by washing in alpha-diastase of appropriate concentration; and then to dewater and dry so as to obtain high-purity edible fiber. Neutral washing liquid and alpha-diastase in this invention have no destruction on the edible fiber in plant mass, and the extraction rate of edible fiber is up to over 95% so that it is especially suitable for extracting edible fiber from plant mass.
Description
The present invention relates to a kind of process of from plant, extracting high-purity edible fiber.
Dietary fiber is a kind of carbohydrate, extensively is present in the plant.In this world before 70 years in generation, dietary fiber once be considered to a kind of can not be for human consumption thereby without any the material of nutritive value.But, along with medical science, biochemistry and biophysical development, people to the noegenesis of dietary fiber the variation of essence.Modern medicine thinks that dietary fiber is actually the indispensable nutriment of human body.Dietary fiber can combine with cholic acid in human body intestinal canal, thereby influences liver and gall circulation, the change human body lipids contents of human body.Dietary fiber can also combine with harmful element and carcinogen, thereby alleviation harmful element and carcinogen are to the harm of intestines wall.Profitable strain in the enteron aisle obtains energy by decomposing dietary fiber, thereby dietary fiber increases the effect of profitable strain quantity in addition.In addition, dietary fiber has very strong water imbibition, can make ight soil water content increase in the enteron aisle, prevent to be hard and dry; Dietary fiber also can stimulate the secretion of the faint-hearted moving and intestinal juice of enteron aisle, increases the lubricity of enteric cavity, thereby helps defecation.In a word, dietary fiber has the defecation of acceleration, prevents the enteron aisle canceration, reduces many-sided alimentary health-care functions such as blood fat and increase intestinal beneficial bacterium group quantity.
Dietary fiber mainly is present in the edibility plant, thereby high-purity edible fiber is mainly extracted from plant.At present, from plant, extract high-purity edible fiber and mainly adopt the chemical washing method, also be about in suitable chemical washing liquid, wash through the material plant body of screening and pulverizing, utilize the chemical reaction removal compositions such as protein, sugar, fat, tannin, pigment, wax and starch wherein of cleaning solution and plant composition, dewater then and dry, promptly obtain highly purified dietary fiber.Cleaning solution of the prior art adopts acid solution or alkali lye more, though the acid ﹠ alkali liquid washing can obtain the very high dietary fiber of purity, but acid ﹠ alkali liquid is in removing plant in other composition, also make greatly dietary fiber hydrolysis and destroyed, its result makes the recovery rate of dietary fiber reduce greatly, generally only can reach about 40%.
Purpose of the present invention promptly is the improvement in addition suitable to the existing washing process that extracts dietary fiber, and is destroyed in leaching process to prevent dietary fiber, thereby significantly improves the recovery rate of dietary fiber.
To achieve these goals, the present invention changes the acid ﹠ alkali liquid washing and is neutral solution washing and the washing of AMS liquid, also promptly at first will be through screening and material plant body heated scrub in suitable neutral cleaning solution of pulverizing, to remove compositions such as protein, sugar, fat, tannin, pigment and wax wherein, and then utilize the AMS liquid of debita spissitudo to wash, to remove starch component wherein.The neutral cleaning solution that adopts among the present invention can be formulated by proper proportion by NaLS, EDTA disodium salt, sodium tetraborate decahydrate, sodium hydrogen phosphate, ethylene glycol monomethyl ether, decahydronaphthalene, sodium sulfite and water; NaLS wherein, EDTA disodium salt and sodium tetraborate decahydrate are mainly used in protein and the fat of removing in the plant; Ethylene glycol monomethyl ether is mainly used in the compositions such as pigment, tannin and wax that dissolve in the plant as solvent; Sodium hydrogen phosphate and decahydronaphthalene are respectively as PH buffer and defoamer, and sodium sulfite then has the effect that improves the cleaning solution boiling point.With above-mentioned all materials is that the formulated cleaning solution of raw material is a kind of neutral cleaning solution, can remove compositions such as protein, fat, pigment, tannin and wax effectively, but dietary fiber be there is no destruction.AMS can decompose the starch component in the plant effectively, and dietary fiber is not had destruction yet.Therefore, adopt the washing of neutral solution and AMS liquid can avoid dietary fiber to go to pot, thereby improve the recovery rate of dietary fiber greatly.Be described in further detail below in conjunction with the method for specific embodiment neutral solution washing and extracting diet fibre of the present invention.
The method of neutral solution washing and extracting diet fibre of the present invention mainly comprises operations such as screening, pulverizing, neutral solution washing, the washing of AMS liquid, dehydration and oven dry, promptly at first the material plant body that extracts dietary fiber is screened and scrubbed clean, yet the material plant body after utilizing pulverizer to scrub is pulverized, and carries out the neutral solution washing then.
The neutral solution washing is carried out in the interlayer heating tank, and wash temperature is 90-100 ℃, and wash time is 1-2 hour.The composition of raw materials of neutral cleaning solution is:
Water 1000ml
NaLS 25-35g
EDTA disodium salt 16-20g
Sodium tetraborate decahydrate 5-8g
Sodium hydrogen phosphate 4-7g
Ethylene glycol monomethyl ether 8-12ml
Decahydronaphthalene 0.5-4ml
The neutral cleaning solution composition of raw materials of sodium sulfite 0.2-1.5g gives an example 1:
Water 1000ml
NaLS 28g
EDTA disodium salt 17.5g
Sodium tetraborate decahydrate 7.3g
Sodium hydrogen phosphate 6.2g
Ethylene glycol monomethyl ether 9ml
Decahydronaphthalene 3ml
The neutral cleaning solution composition of raw materials of sodium sulfite 1.2g gives an example 2:
Water 1000ml
NaLS 30g
EDTA disodium salt 18.6g
Sodium tetraborate decahydrate 6.8g
Sodium hydrogen phosphate 4.6g
Ethylene glycol monomethyl ether 10ml
Decahydronaphthalene 2ml
Sodium sulfite 0.5g
Material plant body after the neutral solution washing enters the washing of AMS liquid after the clear water rinsing.The washing of AMS liquid is also carried out in the interlayer heating tank, and AMS liquid is the AMS aqueous solution, and its concentration is that 2.2-2.8% (g/ml) wash temperature is 36.5-37.5 ℃, and wash time is 15-20 hour.
Material plant body after the AMS liquid washing utilizes centrifuge dewatering earlier after the clear water rinsing, in addition dry in drying machine then, get final product high-purity edible fiber.
The method of neutral solution washing and extracting diet fibre of the present invention does not have destruction to the dietary fiber in the plant, and recovery rate can be up to more than 95%, so be specially adapted to extract dietary fiber from plant.
