Description
Technical field
The present invention relates to converted starch preparation technical fields, and in particular to a kind of preparation work of Ultra Tex 2
Skill.
Background technique
Ultra Tex 2, white powder is odorless, tasteless, soluble easily in water, does not dissolve in organic solvent.It forms sediment with original
Powder is compared, and solubility, swelling power and transparency significantly improve；Aging tendency is substantially reduced, and freeze-stable improves, and can be resisted
It is hot, antiacid；Ultra Tex 2 is a kind of important composite modified starch, while it is excellent that there is crosslinking, esterification to be denaturalized
Point is widely used in the food such as jam, sauce, sauce, salad dressing, Yoghourt, quick-frozen food, cake, meat products.It hands over
Connection starch can make the thickener and stabilizer of salad juice, its viscosity does not reduce during low PH and high speed homogenization；Tinned food
High-temperature heating sterilization require the thermal stability of gelatinized corn starch high, appropriately crosslinked converted starch is able to satisfy this requirement, using paste
Change or the slow crosslinked starch of swelling rate, viscosity is low when tinned food can be made to start, and heat transfer is fast, heats rapidly, utilizes moment
Sterilization, the thickening after sterilizing refined can give the properties such as suspension and structure organization；Crosslinked starch freezing also with higher is steady
Qualitative and freeze-thaw stability, in the freezing of low temperature long period or freeze thawing, it is more to melt repetition especially suitable for applying in frozen food
Secondary, food is still able to maintain original institutional framework and does not change；In addition, crosslinked starch is also used to sweet tea cake, fruit filling, pudding and oil
In the Orly of fried food.
The Ultra Tex 2 preparation provided in the prior art mostly uses cross-linked esterification to prepare, but preparation process item
Part is different, and the Ultra Tex 2 performance prepared is different.
Chinese patent literature (publication number: CN108329396A) discloses a kind of Ultra Tex 2 converted starch
Preparation method, the preparation method of Ultra Tex 2 converted starch of the present invention, with waxy corn starch be original
Material, sodium trimetaphosphate is crosslinking agent, using acetic anhydride as esterifying reagent, by be crosslinked-acetylization reaction is prepared for required acetyl
Change PASELLI EASYGEL converted starch, preparation process condition is different, and obtained converted starch performance is different, thus the present invention is ground
Study carefully optimal converted starch performance obtained by different technique.
Chinese patent literature (publication number: CN107163152A) discloses a kind of two starch phosphorus of acetylation in oyster sauce
Ultra Tex 2 is prepared to the water retention property of oyster sauce by recombination reaction in the preparation method of acid esters, this method
Height, it is possible to prevente effectively from oyster sauce generation water outlet lamination in storage, but the Ultra Tex 2 freeze-thaw stability,
The performances such as the degree of cross linking are not fine.
