Abstract
A kind of porous tapioca starch sodium octenyl succinate, preparation method is 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 efficiently prepare octenyl succinic by raw material of tapioca
The method of 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 ocentyl succinic para arrowroot efficient, easy to operate
The preparation method of powder ester, the microencapsulation wall available for liposoluble substance.
A kind of porous tapioca starch sodium octenyl succinate, preparation method comprises the following steps：
(1) starch is handled：Take second alcohol and water, in mass ratio 2:1 mixing, is then uniformly sprayed on tapioca, until forming sediment
The ethanol content of powder is 7-8%, carries out superheated steam processing, and superheat steam temperature is 180-200 DEG C, and action time is 15-18
Minute；
(2) esterification：Using the starch after step (1) processing as raw material, add water until the water content of starch is 72-
75%, using octenyl succinic acid anhydride and alcohol mixeding liquid as esterifying agent, octenyl succinic acid anhydride addition is the 8- of starch quality
10%, when starch water content is reduced to 8-10% during esterification, course of reaction are carried out during temperature is 60-65 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 12-14% ethanol water, the 2nd time is the ethanol water for using ethanol content 7-8%, the
3 times are to drink water washing；
(4) cold nebulization：The starch octenyl succinate anhydride isolated and purified is added water into tune pH to 3.9-4.0, sprayed
It is dried to obtain product；The EAT of spray drying is 160-165 DEG C, and leaving air temp is 70-72 DEG C.The ocentyl succinic
The mass ratio of acid anhydride and ethanol is 1:6.5-6.8.
Advantage of the invention is that：
1st, in starch treatment processes, ethanol water is uniformly sprayed on starch, have very well during superheated steam processing
Collaboration cavitation, while ethanol volatilization can allow starch 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 tapioca, until forming sediment
The ethanol content of powder is 8%, carries out superheated steam processing, and superheat steam temperature is 180 DEG C, and action time is 18 minutes；
(2) esterification：Using above-mentioned starch as raw material, add water until the water content of starch is 75%, with octenyl succinic
Acid anhydrides and alcohol mixeding liquid are esterifying agent, and the mass ratio of octenyl succinic acid anhydride and ethanol is 1:6.5, octenyl succinic acid anhydride adds
Dosage is the 10% of starch quality, and starch is aqueous in esterification, course of reaction is carried out during temperature is 65 DEG C of concentration reactors
Amount stops concentration reaction when being reduced to 10%, 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 14%
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 165 DEG C, and leaving air temp is 72 DEG C.
Through testing and detecting, 28% tapioca ester embedding 43%DHA, embedding rate reaches more than 95%, and stability is good, goods
The frame phase was up to more than 10 months.
