[0071] Embodiment 1 A kind of preparation method of octenyl potato starch succinate comprises the following steps:

[0072] (1) Mix 20kg of potato starch produced by Gansu Tengsheng Starch Co., Ltd. with 38kg of water, and stir at 30°C with a 100LBLD1.1-100 stainless steel steam heating constant temperature stirring reactor produced by Wuxi Dongguan Machinery Manufacturing Co., Ltd. A starch emulsion with a concentration of 35% is formed, and the pH value is adjusted to 7.5 with a sodium hydroxide solution having a mass concentration of 2%.

[0073] (2) Dilute 0.6 kg of octenyl succinic anhydride with 20 kg of Tween mixture to a solution with a concentration of 3%, wherein the Tween mixture refers to a mixture of 3 parts by mass of Tween and 95 parts by mass of water.

[0074] (3) Mix the starch emulsion with the diluted alkenyl succinic anhydride in the step (2), and put it into a 100LBLD1.1-100 type stainless steel steam heating constant temperature stirring reactor to react...

Embodiment 2

[0077] Embodiment 2 A kind of preparation method of octenyl potato starch succinate comprises the following steps:

[0078] (1) 20kg potato starch is mixed with 32.6kg water, and at 35 DEG C, it is stirred into a starch emulsion with a milk concentration of 38% with a stainless steel steam heating constant temperature stirring reactor, and the pH value is adjusted with a mass concentration of 2% sodium hydroxide solution to 7.7.

[0079] (2) Dilute 0.6 kg of octenyl succinic anhydride with 15 kg of Tween mixture to a 4% solution; wherein the Tween mixture refers to a mixture of 4 parts by mass of Tween and 96 parts by mass of water.

[0080](3) The starch emulsion is mixed with the alkenyl succinic anhydride diluted in the step (2), and put into a stainless steel steam heating constant temperature stirring reactor to react to form a reaction system, and then use a 2% NaOH solution with a mass concentration The pH value was kept at 7.7, and the reaction time was 3.5 hours unti...

Embodiment 3

[0083] Embodiment 3 A kind of preparation method of octenyl potato starch succinate comprises the following steps:

[0084] (1) 20kg potato starch is mixed with 28kg water, and at 40 DEG C, it is a starch emulsion with a milk concentration of 42% to be stirred with a stainless steel steam heating constant temperature stirring reactor, and the sodium hydroxide solution with a mass concentration of 2% is used to adjust the pH value to 7.8.

[0085] (2) Dilute 0.6kg octenyl succinic anhydride with 12kg Tween mixed solution into a solution with a concentration of 5%; wherein the Tween mixed solution means that the solid-to-liquid ratio is 5 parts by mass of Tween and 97 parts by mass of water of the mixture.

[0086] (3) The starch emulsion is mixed with the alkenyl succinic anhydride diluted in the step (2), and put into a stainless steel steam heating constant temperature stirring reactor to react to form a reaction system, and then use a 2% NaOH solution with a mass concentrat...

Abstract

The invention relates to a method for preparing octenylsuccinate potato starch ester, which comprises the following steps: (1) mixing potato starch and water into a starch emulsion of which the temperature is between 30 and 40 DEG C and the emulsion concentration is 35 to 45 percent, and adjusting the pH value to between 7.5 and 8.0; (2) diluting octenyl succinic anhydride into solution with the concentration of 3 to 5 percent by using tween mixed solution; (3) mixing the starch emulsion with the diluted alkenyl succinic anhydride in the step (2), and using NaOH solution to keep the pH value between 7.5 and 8.0 until the reaction is finished so as to obtain an octenylsuccinate potato starch ester emulsion; and (4) using hydrochloric acid solution to adjust the pH value of the octenylsuccinate potato starch ester emulsion to between 6.5 and 7.0, standing the mixture, removing the supernatant, washing, drying and crushing the mixture, and screening the powder by a sieve of 80 meshes. The method has a simple production process and simple operations, is easy to grasp and has a low cost and small pollutions, and the octenylsuccinate potato starch ester produced by the method has high effective material content and stable product performance.

Description

technical field [0001] The invention relates to a method for preparing starch octenyl succinate, in particular to a method for preparing potato starch octenyl succinate. Background technique [0002] my country is a large starch production and consumption country, but with the rapid development of industrial production technology, some properties of raw starch no longer meet the requirements of new equipment and new processes, and it needs to be denatured to obtain better application effects. [0003] Starch octenyl succinate is a new type of edible modified starch glue, which has two properties of hydrophilic and hydrophobic, which can greatly improve the quality of the product. It is widely used in food, pharmaceutical, textile and chemical industries, and has rich economic benefits. . Although there have been research reports on the preparation of starch octenyl succinate, these studies have quantitatively mixed together starch milk, acid anhydride and emulsifier during ...
