Embodiment 1

[0025] Embodiment 1: first add 180 kilograms of water to 100 kilograms of waxy starches and adjust it into 20-23Be starch slurry in the reactor, constantly stir, and add the sodium hydroxide solution that mass concentration is 3-3.8% in the kettle to adjust the pH value to 7.5, Add 4.5 kg of octenyl succinic anhydride, keep the temperature at 30±1°C to make it react, and continuously dropwise add sodium hydroxide solution with a mass concentration of 3-3.8% during the reaction to maintain the pH value at 7.5, when the pH value no longer drops After continuing to react for 1 hour, add mass concentration and be that 8-10% hydrochloric acid solution is neutralized to pH value 6.0-7.0, add 200 kilograms of water washings, sedimentation in the kettle, then wash, sedimentation in the same way, to remove impurity (chlorination) Sodium or other chemical residues) to obtain the primary product of octenyl succinate starch, adjust the primary product into a starch milk with a mass concent...

Embodiment 2

[0026] Embodiment 2: The steps are the same as in Embodiment 1, except that the pH value of the esterification process is maintained at 8.0, and the reaction temperature is maintained at 30±1°C.

Embodiment 3

[0027] Embodiment 3: The steps are the same as in Embodiment 1, except that the pH value of the esterification process is maintained at 8.5, and the reaction temperature is maintained at 30±1°C.

Abstract

The present invention discloses a kind of pregelatinized octalkenyl succinate starch and its preparation method. It is made up by using waxy starch, octalkenyl succinic anhydride, hydrochloric acid and sodium hydroxide as raw material and making said raw materials undergo the processes of mixing paste, esterification, neutralization, washing, drying, screening, mixing paste, pregelatinizing, pulverizing, screening and packaging. Besides, said invention also provides its concrete application range.

Description

technical field [0001] The invention relates to a modified starch and a preparation method thereof, in particular to a pregelatinized octenyl succinate starch and a preparation method thereof. Background technique [0002] In recent years, the domestic emulsifier market has expanded. With the continuous improvement of living standards, people are increasingly aware of the importance of adding various emulsifiers in food processing. Domestic related products mainly rely on imports, especially octenyl amber Ester starch, because of its extremely strict production process and special raw materials, it is only controlled by a few large foreign companies. The added value of this product is extremely high, and the supply exceeds demand. However, the application of octenyl succinate starch products sold in the market in the field of thickening emulsifiers is limited due to reasons such as their viscosity and water solubility. Contents of the invention [0003] The purpose of the...
