Description
Technical field
The present invention relates to a kind of preparation method of converted starch, belong to starch manufacture field.
Background technology
On the basis of inherent characteristic possessed by native starch, to improve the performance of starch, expanding its application, profit
With physics, chemistry or enzymatic treatment, new functional group is introduced on starch molecule or changes starch molecule size and starch granules
Property, so as to change the natural characteristic of starch（Such as：Gelatinization point, thermoviscosity and its stability, freeze-thaw stability, gel force, into
Film, transparency etc.）, make it more suitable for the requirement necessarily applied.This to pass through secondary operation, the starch for changing property is referred to as
For converted starch.
Physical modification just refers to method such as sootiness, humid heat treatment, annealing, extrusion process, the superfine powder using physics
Broken, microwave treatment, ultrasonication and radiation treatment etc., starch microstructure is changed and it is manufactured have industry needed for
The feature converted starch wanted.Chemical modification just refers to using chemical method and manufactured converted starch, that is, utilizes starch molecule
On alcoholic extract hydroxyl group or glucose ring chemical constitution change and method that starch derivatives is made.Enzyme process denaturation is exactly to utilize life
Thing enzyme hydrolysis starch prepares a kind of method of converted starch.It digests mechanism：Under certain environmental conditions, with biology enzyme with
Starch is mixed, and enzyme and starch storage crop regular hour are made under the conditions of certain temperature, make starch occur incomplete degradation reaction and
Converted starch is made.But there is problems with this method：Reaction temperature is high, reaction time length, and yield is low, obtained converted starch
Freeze-thaw stability is poor, and film forming is bad.
Therefore, the converted starch that a kind of freeze-thaw stability is good, film forming is good is developed, there is necessary meaning.
The content of the invention
The technical problems to be solved by the invention：It is poor for traditional converted starch freeze-thaw stability, the bad disadvantage of film forming
A kind of end, there is provided preparation method of converted starch.
In order to solve the above technical problems, the present invention is using technical scheme as described below：
（1）Starch is put into container with water and is well mixed, is placed in being gelatinized at 60~65 DEG C, it is equal to add sodium pyrophosphate mixing
It is even, stand, be cooled to room temperature, the material in container is freeze-dried, collect dried object；
（2）Dried object and beeswax are subjected to ball milling, collect ball-milled mixtures, ball-milled mixtures are uniform with absolute ethyl alcohol and stirring,
It is put into steam blasting device and carries out steam blasting, collects explosion thing；
（3）By explosion thing and hydrogen peroxide oxidation processes at 50~55 DEG C, ethylene glycol is added, is stood, it is dry to carry out spraying while hot
It is dry, collect spray-dried product；
（4）Spray-dried product, aluminium chloride and chloroacetic chloride are put into reactor, using hydrogen shield, design temperature is 90~95
DEG C, stirring reaction, then 60~65 DEG C are cooled to, tyrosine is added, 30~50min is stirred, is cooled to room temperature, discharges, collects out
Material；
（5）Material will be gone out to be freeze-dried, collect freeze-drying thing, after reusing absolute ethyl alcohol washing freeze-drying thing, dried
It is dry, ball milling, sieving, collect sieving particle, you can obtain converted starch.
The starch is any one in cornstarch, tapioca, farina, water caltrop starch.
The step（1）The mass ratio of middle starch and water is 1:4~6, gelatinization time is 50~60min.
The step（1）The addition of middle sodium pyrophosphate is the 7~10% of starch quality.
The step（2）The mass ratio of middle dried object and beeswax is 5~7:1, the quality of ball-milled mixtures and absolute ethyl alcohol
Than for 1:3.
The step（2）Middle steam blasting condition is that pressure is 3~5MPa, and temperature is 40~45 DEG C, the dimension pressure time is 2~
4min。
The step（3）The mass ratio of borehole blasting thing and hydrogen peroxide is 1:4, the addition of ethylene glycol is blasting substance amount
10~15%.
The step（4）The mass ratio of middle spray-dried product, aluminium chloride and chloroacetic chloride is 6~9:0.8~1.2:2~3, junket
The addition of propylhomoserin is the 1.5~2.0% of spray-dried product quality.
Compared with other method, advantageous effects are the present invention：
（1）The present invention is bleached and cleaned to starch by sodium pyrophosphate, and is filled with materials such as the acids in beeswax, fatty alcohols
Point mixing, then by steam blasting, expand the gap between starch structure, make free fatty, free alkyl alcohol filling gap,
In the environment of ethylene glycol, starch is handled using hydrogen peroxide, the carboxyl in starch is exposed, it is right in the presence of aluminium chloride
Starch carries out acetylation, while free fatty, free alkyl alcohol and tyrosine are combined, and forms space net structure,
Freeze-thaw stability is improved, is activated finally by ball milling, while starch is carried out chain rupture, increases amylose content, improves stream
Dynamic performance, and then improve film forming；
（2）Preparation process of the present invention is simple, and reaction temperature is gentleer, and high income is up to 90~95%.

~-15 DEG C, naturally to thaw is taken out after 24h；If anhydrous precipitation, multigelation, untill having elutriation to go out, then it is being positioned over
20min is centrifuged in 3000r/min centrifuges, abandoning supernatant, weighs sediment quality, calculates syneresis rate；
2nd, viscosimetric analysis：Converted starch is configured to the starch emulsion that mass fraction is 3% with distilled water, heating stirring is to 95 DEG C
Constant temperature 30min, it is moved into constant temperature in water-bath after being fully gelatinized and sample, then be positioned over interior and allow to cool to room temperature, use
Digital rotation viscometer is detected；
3rd, film forming determines：The converted starch emulsion that mass fraction is 5% is prepared with 500mL beakers, after slightly stirring, is put rapidly
It is placed in 95 DEG C of constant water bath box, is gelatinized while stirring, after being gelatinized 20min, adds 1%（Account for the mass fraction of converted starch breast）'s
Glycerine, after being stirred for 5min, 35~40 DEG C are cooled to, then pour into and coating is cast in homemade poly (methyl methacrylate) plate, it is uniformly rear to place
60 DEG C of dry 4~5h in drying box, film is taken off after film forming, observe film forming.
As a result as shown in Table 1.
Table one：
| Detection project | Example 1 | Example 2 | Example 3 | Reference examples |
| Freeze-thaw stability（Syneresis rate）/ % | 15.2 | 14.8 | 14.3 | 23.40 |
| Viscosity/Pas | 0.096 | 0.094 | 0.090 | 0.099 |
| Film forming | Film is complete, and transparency is good | Film is complete, and transparency is good | Film is complete, and transparency is good | Film is partially complete, and transparency is good |
As seen from the above table, converted starch of the present invention has preferable freeze-thaw stability, while has preferable film forming.
