Abstract
A kind of high-purity octenylsuccinate potato starch ester and its production method, are mainly included the following steps that：Starch processing, esterification, isolate and purify and the step such as cold nebulization.The present invention's is particular in that：Esterification is carried out during concentration, the esterifying efficiency of starch is higher；Meanwhile, the ethanol water gradually reduced using ethanol content carries out washing purifying, can lift product purity.
Description
Technical field
The invention belongs to technical field of modified starch, and in particular to octenyl amber is efficiently prepared as raw material using farina
The method of amber acid-starch ester.
Background technology
Starch octenylsuccinate is a major class converted starch, and only one in grocery trade is allowed to use in China
Plant, i.e. starch octenyl succinate anhydride.Starch octenyl succinate anhydride be white powder, nontoxic, free from extraneous odour, can be molten in the hot water
Solution, can dissolve, transparent liquid has good stability in acid-base solution after being handled through pre-gelatinized in cold water.Starch
After being acted on through octenyl succinic acid anhydride, the viscosity of starch is improved, and the anti-aging stability of cooking material is improved.Sometimes, this derivative
Thing can also improve the texture feature of starch.
Starch octenylsuccinate is best suitable for the wall material of microencapsulation, and it can substitute gum arabic, can be to food
Product dispensing such as essence, pigment, vitamin, mineral matter, enzyme preparation and microorganism carry out embedding treatment.
The content of the invention
React gentle it is an object of the invention to provide one kind, separate octenylsuccinate potato efficient, easy to operate
The preparation method of starch ester, the microencapsulation wall available for liposoluble substance.
A kind of high-purity octenylsuccinate potato starch ester and its production method, comprise the following steps：
(1) starch is handled：Take second alcohol and water, in mass ratio 2:1 mixing, is then uniformly sprayed on farina, until
The ethanol content of starch is 10-12%, carries out x-ray irradiation processing, exposure rate is 8-10KGy/h, and irradiation time is 12-14
Minute；
(2) esterification：Using the starch after step (1) processing as raw material, add water until the water content of starch is 70-
72%, using octenyl succinic acid anhydride and alcohol mixeding liquid as esterifying agent, octenyl succinic acid anhydride addition is the 12- of starch quality
14%, when starch water content is reduced to 9-11% during esterification, course of reaction are carried out during temperature is 62-65 DEG C of concentration reactor
Stop concentration reaction, obtain starch octenyl succinate anhydride；
(3) isolate and purify：3 washings are carried out to starch octenyl succinate anhydride and are centrifuged；3 washings：Adopt for 1st time
Washed with ethanol content 16-18% ethanol water, the 2nd time is to be entered using ethanol content 7-8% ethanol water
Row washing, the 3rd time is to drink water washing；
(4) cold nebulization：The starch octenyl succinate anhydride isolated and purified is added water, adjusts pH to 3.9-4.1, is sprayed
It is dried to obtain product；The EAT of spray drying is 168-170 DEG C, and leaving air temp is 73-75 DEG C.
Step (2) described esterifying agent：The mass ratio of octenyl succinic acid anhydride and ethanol is 1:7.0-7.2.
Advantage of the invention is that：
1st, in farina processing procedure, ethanol water is uniformly sprayed on farina, when carrying out X-ray processing
With good collaboration cavitation, while ethanol volatilization can allow farina porous.
2nd, esterification is carried out in concentration reactor, esterification, control concentration speed is carried out during concentration
And reaction speed, the esterifying efficiency of starch greatly improves.
3rd, after starch esterification reaction, the ethanol water gradually reduced using ethanol content carries out washing purifying, can be very
The octenyl succinic acid anhydride of residual is adsorbed well, increases product purity, while not destroying the stability of starch ester product.
Embodiment
Embodiment one
(1) starch is handled：Take second alcohol and water, in mass ratio 2:1 mixing, is then uniformly sprayed on farina, until
The ethanol content of starch is 12%, carries out x-ray irradiation processing, and exposure rate is 10KGy/h, and irradiation time is 12 minutes；
(2) esterification：Using above-mentioned starch as raw material, add water until the water content of starch is 72%, with octenyl succinic
Acid anhydrides and alcohol mixeding liquid are esterifying agent, and the mass ratio of octenyl succinic acid anhydride and ethanol is 1:- 7.2, octenyl succinic acid anhydride
Addition is the 14% of starch quality, and starch contains in esterification, course of reaction is carried out during temperature is 65 DEG C of concentration reactors
Water stops concentration reaction when being reduced to 11%, obtain starch octenyl succinate anhydride；
(3) isolate and purify：3 washings are carried out to starch ester and are centrifuged, the 1st time water-soluble using the ethanol of ethanol content 18%
Liquid is washed, and the 2nd time is the ethanol water for using ethanol content 8%, and the 3rd time is to drink water washing；
(4) cold nebulization：The starch octenyl succinate anhydride isolated and purified is added water into tune pH to 4.0, is spray-dried
Obtain product；The EAT of spray drying is 170 DEG C, and leaving air temp is 75 DEG C.
Through test and detect, 32% octenylsuccinate potato starch ester embedding 45%DHA, embedding rate reach 95% with
On, stability is good, and shelf life was up to more than 10 months.
