Abstract
The invention discloses a preparation method of super sodium carboxymethyl starch (Disintegration King), characterized by using potato starch as a raw material and chloroacetic acid as an etherifying agent to prepare the super sodium carboxymethyl starch. The raw materials for preparing the super sodium carboxymethyl starch comprise 80 weight parts of ethanol as a diluent, 1 weight part of water, 1.8 weight parts of sodium hydroxide, 10 weight parts of potato starch, 2 weight parts of chloroacetic acid, and 1 weight part of hydrochloric acid. According to the invention, by using the potato starch as the raw material to produce the super sodium carboxymethyl starch, the cost of the super sodium carboxymethyl starch is greatly reduced, the yield is raised, and the application is extended.
Description
Technical field
The present invention relates to a kind of super Preparation of sodium carboxymethy starch method.
Background technology
Super sodium starch glycolate (disintegration king) is the powder of white, and good fluidity has good water-solubility, its aqueous solution clear, colorless, good stability.Soaking effect is 5 times of common sodium starch glycolate.The instead gelatin is as the starting material of making capsule, tablet, sugar-coat.Have stronger water-absorbent and swelling property; In cold water, can comparatively fast steep and rise; And suction back grain expansion and not dissolving; Do not form colloidal solution, the continuation that does not hinder moisture is infiltrated and influence the further disintegration of tablet, is used as insoluble drugs and soluble agents tablet, the efficient disintegrating agent of medicinal tablet, vehicle.
Medicine industry, super sodium starch glycolate (disintegration king): the instead gelatin, as the starting material of making capsule, tablet, sugar-coat, make the disintegrating agent of tablet, vehicle.
Foodstuffs industry; Super sodium starch glycolate (disintegration king) be applied in the different food; Show multiple functions such as thickening, suspension, emulsification, stable, conformal, film forming, expanded, fresh-keeping, acidproof and health care, it is the best product that replaces CMC that performance is superior to CMC 99.5 (CMC).The food grade sodium starch glycolate is widely used in products such as milk, beverage, frozen product, snack food product, cake, syrup.
Publication number is that CN1490337, patent name are the Chinese invention patent of " superhigh viscosity carboxymethyl sodium starch and preparation method thereof "; Relate to a kind of superhigh viscosity carboxymethyl sodium starch and preparation method thereof; Product of the present invention is made up of starch, ethanol, Mono Chloro Acetic Acid, caustic soda, five kinds of main raw materials of linking agent, and preparation method of the present invention comprises preparation, alkalization, crosslinked, etherificate, neutralization, washs, takes off process steps such as liquid, distillation, drying, pulverizing, packing, and the present invention compared with prior art; Through the product that obtains behind the complex denaturation; Viscosity substantially exceeds the market other products, and more stable quality, concentration are that 2% o'clock maintenance viscosity can reach 3 months.Alternative CMC, thus a large amount of purified cottons can be practiced thrift, also alternative sodium-alginate, price is than low 20%-30%; Product superhigh viscosity carboxymethyl sodium starch of the present invention has higher viscosity, stronger clinging power and emulsifying property, perviousness preferably, can be widely used in fields such as welding electrode, food, daily use chemicals, oil, weaving, printing and dyeing, medicine, tackiness agent.
But also do not see the report that useful yam starch is the super sodium starch glycolate of raw material production; And yam starch is extensive in Chinese resource; With low cost, if can use yam starch as the super sodium starch glycolate of raw material production, with the cost that reduces super sodium starch glycolate greatly; Improve its output, enlarge its purposes.
Summary of the invention
The technical issues that need to address of the present invention just are to overcome the defective of prior art; A kind of super Preparation of sodium carboxymethy starch method is provided; It uses yam starch to be the super sodium starch glycolate of raw material production; With the cost that reduces super sodium starch glycolate greatly, improve its output, enlarge its purposes.
For addressing the above problem, the present invention adopts following technical scheme:
The invention provides a kind of super Preparation of sodium carboxymethy starch method, said method prepares super sodium starch glycolate for to use yam starch to cook etherifying agent as raw material, Mono Chloro Acetic Acid.
The parts by weight of raw materials proportioning for preparing super sodium starch glycolate is: 80 parts of ethanol are as thinner, 1 part in water, 1.8 parts in sodium hydroxide, 10 parts of yam starchs, 2 parts of Mono Chloro Acetic Acids, 1 part of hydrochloric acid;
Concrete preparation process is:
The first step, mixing raw material: in reaction kettle, behind adding ethanol, water, the sodium hydroxide, be warming up to 70 ℃, be incubated 30 minutes;
In second step, alkalization: the mixing raw material of the first step is cooled to 30 ℃, adds yam starch, stirred 1 hour, temperature is controlled at 25-40 ℃, alkalizes; Alkalization finishes, and after reaction kettle is evacuated to 0.05～0.07mpa, adds chloroacetic acid solution, keeps 30 minutes;
In the 3rd step, etherificate: temperature rises to 70-80 ℃, keeps 4 hours;
In the 4th step, the neutralization washing: etherificate is cooled to below 40 ℃ after finishing, and adds hydrochloric acid and neutralizes, washs.
In the 5th step, whiz: with the centrifugal drying machine that is conveyed into of material, carry out dry materials through horizontal spiral centrifuge, the exsiccant material is pulverized the back packing.
Yam starch is extensive in Chinese resource, and is with low cost, and the present invention uses yam starch to be the super sodium starch glycolate of raw material production, reduces the cost of super sodium starch glycolate greatly, improves its output, enlarges its purposes.
