Description
Technical field
The present invention relates to a kind of cross-linking modified starch, more particularly to one kind adds succinic acid two using banana lily starch as raw material
Epoxy prapanol ester crosslinking agent prepares the technique of crosslinked starch, belongs to starch Chemical Industry field.
Background technology
Porous-starch is one kind of modified starch, porous to generate very big specific surface area, porous-starch and other adsorbents
It compares, in addition to good absorption property, also with biodegradable, simple production process, characteristics, the quilt such as is widely used
It is widely used in the industries such as food, medical and health, agricultural, papermaking, printing, cosmetics, detergent, adhesive.
At present, native starch is modified and prepares porous-starch and be mainly the following method：First, using machinery
Method, such as pass through the mechanical impacts such as ball-milling technology；Second is that physical method, such as pass through ultrasonic irradiation or spray art；
Third is biochemical method, such as alcohol is denaturalized or sour water solution, in above-mentioned several method, the machines such as ultrasonic irradiation, ball-milling technology
The production cost that tool hits method is higher, is not easy to realize industrial industrialization；And spray-on process and alcohol are denaturalized that be formed is a kind of reality
The popcorn polymer sphere of the heart, suction-operated are only occurred in the rough gully of spherome surface, and adsorbance is than relatively limited；Sour water solution
Method reaction rate under gelatinization point is slower, and degradation differs, and is not easy to be formed poroid.And enzyme degradation technique is used, it is made by adjusting
Standby process conditions and addition suitable adjuvants control spherex grain size and microcellular structure, the modified porous starch specific surface of preparation
Product is big, has wide application prospect.
Enzyme degradation technique method is to form it into porous-starch, but this method can make shallow lake in starch using diastatic action
Powder structure shows as resistance to mechanical destroys force difference, anti-Swelling Capacity weakens etc. by a degree of destruction.In order to make up porous shallow lake
These in powder structure are insufficient, by adding crosslinking agent, carry out chemical modification to it, and the alcoholic extract hydroxyl group of starch molecule is in containing binary
Or the chemical reagent reaction of polynary functional group, make to join together to form sediment so as to prepare a kind of crosslinking between the hydroxyl of different starch molecules
Powder, the present invention is using banana lily starch as raw material, by adding succinic acid diepoxy propyl alcohol ester crosslinking agent, to the porous-starch of preparation into
Row crosslinking, the relative molecular mass of porous-starch becomes larger after crosslinking, influences have high stability to heat, acid and shearing force.
