Abstract
The invention discloses a kind of methods for the converted starch that high absorption property is prepared using Gorgon fruit starch as raw material.Gorgon fruit starch is first taken as raw material, starch solution is made through dissolving, heating water bath, lauryl sodium sulfate is added in after cooling and is fully dissolved, again through heating water bath, then it suitable carbohydrase and is stirred continuously, appropriate glutaric acid solution is added again, fully cleans and filters again after reaction, and finally vacuum drying can obtain a kind of converted starch of high absorption property.
Description
Technical field
The present invention relates to a kind of converted starch, more particularly to a kind of technique that converted starch is prepared using taro belongs to shallow lake
Powder chemical field.
Background technology
Converted starch is a kind of starch by being modified, and such starch has some special physicochemical properties.Last decade
Come, the yield of world's converted starch increases rapidly, and the annual output of world's converted starch is close to more than 800 ten thousand tons at present, Sino-U.S.
More than 300 ten thousand tons of state, more than 200 ten thousand tons of Europe, more than 60 ten thousand tons of Japan, more than 50 ten thousand tons of Thailand, more than 100 ten thousand tons of China.China's denaturation is formed sediment
The application of powder still falls within emerging service, no matter from the type, quality or application range of converted starch, all has with foreign countries larger
Difference.If calculated with the converted starch quantity needed for the current every profession and trade in China, annual requirement ten thousand tons of 100-200 it
Between.
At present, it prepares converted starch and is mainly the following method：First, physical method, for example, by ultrasonic irradiation or
Person's spray art；Second is that using mechanical means, such as pass through the mechanical impacts such as ball-milling technology；Third is biochemical method, such as alcohol
Denaturation or sour water solution, in above-mentioned several method, the production cost of the mechanical impacts method such as ultrasonic irradiation, ball-milling technology compared with
Height is not easy to realize industrialization；And spray-on process and alcohol are denaturalized that be formed is a kind of solid popcorn polymer sphere, suction-operated only occurs
In the gully of surface irregularity, adsorbance is limited, and application prospect is pessimistic.Acid-hydrolysis method reaction rate under gelatinization point
Relatively slow, degradation differs, and randomness is strong, is not easy to be formed poroid, limits the application of acid system.
Gorgon fruit contains abundant starch, and content of starch is up to more than 50%, and most of starch granules is polygonal.This hair
It is bright by using Gorgon fruit starch as raw material, it is appropriate by adjusting preparation process condition and addition using enzyme degradation technique method
Auxiliary agent prepares a kind of converted starch of high absorption property, and the converted starch of preparation can be as the load of adsorption function substance
Body.
Invention content
It is main the object of the present invention is to provide a kind of method that taro converted starch is prepared using Gorgon fruit starch as raw material
Method and step it is as follows：
(1) a certain amount of Gorgon fruit starch is taken, appropriate distilled water is added in, is placed in water-bath and heats, and be stirred continuously with blender, make shallow lake
Powder is swollen, divides, forming homogeneous paste starch solution in water；
(2) appropriate lauryl sodium sulfate is added in after paste starch solution is cooled to room temperature, and is stirred to dissolve uniformly；
(3), again by system by heating water bath, a certain amount of carbohydrase is added in, and stirring makes fully to react；
(4) add in a certain amount of glutaric acid reactor, and stirring makes fully to react；
(5) cleaned, filtered with acetone, is washed with water, filtered；
(6) filtration product is put into vacuum drying to get product.
Preferentially, step (1) in, water bath heating temperature be 40-60 DEG C.
Preferentially, step (2) in, the amount of the lauryl sodium sulfate of addition and the ratio of taros'starch are 1mL:5g.
Preferentially, step (3) in, the carbohydrase of addition and the quality of taros'starch are 1 than ratio：100, system water-bath adds
Hot temperature is 40-70 DEG C, reaction time 5-10h.
Preferentially, step (4) in, the amount of the glutaric acid of addition and the ratio of taros'starch are 1mL:100g.
The present invention has following advantages and characteristic：
(1) the converted starch stability prepared is good；
(2) preparation process is simple, easily realizes industrialization.
