specific Embodiment approach 1

[0007] Specific embodiment one: the preparation method of low-viscosity potato starch octenyl succinate in the present embodiment is carried out according to the following steps: one, take by weighing potato refined starch, add ultrapure water and stir, potato starch dry base The mass ratio to pure water is 2:3, then add concentrated hydrochloric acid to make the concentration of HCl in the reaction system 0.78~0.8mol / L, then acidolysis reaction in a constant temperature water bath at 45~50℃ for 2.5~3h, and then use the mass concentration Adjust the pH value of 1.8%~2% sodium hydroxide solution to 6.50~7.00, then wash with deionized water until no chloride ions appear in the washing liquid, then add ultrapure water and stir well to obtain starch milk, wherein starch milk The dry basis mass content of potato starch in medium is 39%~40%; 2. Under the conditions of 33~35°C and pH value of 7.50±0.05, add octenyl with a mass concentration of 3% to the starch milk dropwise within 1.5...

specific Embodiment approach 2

[0009] Specific embodiment 2: This embodiment differs from specific mode 1 in that: the mass concentration of the concentrated hydrochloric acid described in step 1 is 35%-37%. Other steps and parameters are the same as in the first embodiment.

specific Embodiment approach 3

[0010] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that: in step 3, the drying temperature is 50° C., and the drying time is 3-5 hours. Other steps and parameters are the same as those in Embodiment 1 or Embodiment 2.

Abstract

The invention relates a preparation method of low-viscosity potato octenyl succinic acid starch ester, which solves the problem that potato octenyl succinic acid starch ester prepared by the prior art has overhigh viscosity and is not suitable to being used as a microcapsule wall material. In the invention, the low-viscosity potato octenyl succinic acid starch ester is prepared from refined potato starch as a raw material by the processes of acid hydrolysis and the esterification of compound octenyl succinic anhydride. The potato octenyl succinic acid starch ester prepared by the method has low viscosity, no toxicity, no odor, and excellent emulsifying property, which determines that the low-adhesion potato octenyl succinic acid starch ester is the first choice of the wall material of a microcapsule technology and broadens the application field of the potato starch and derivatives.

Description

technical field [0001] The invention relates to a preparation method of starch octenyl succinate. Background technique [0002] With the advancement of industry and the development of science and technology, the direct application of native starch in modern industry is very limited, especially when it is applied in the case of new technology, new technology and new equipment, which reflects the lack of functionality of native starch. On the basis of the inherent characteristics of native starch, it is one of the development trends of starch industry to improve the natural properties of starch, increase some functions or introduce new characteristics through physical, chemical and biotechnology methods, and broaden the application field of starch. Potato starch has high whiteness, tasteless and good safety, which is an ideal application wall material for microcapsule technology. For this reason, the development of the modified starch industry is changing with each passing da...
