Embodiment 1

[0042] Embodiment 1, a kind of potato octenyl starch succinate degree of substitution assay method:

[0043] Accurately weigh 2.0 g of the sample and place it in a 250 mL beaker, wet it with 10 mL of 90% isopropanol, stir for 10 min, add 15 mL of 2.5 mol / L hydrochloric acid-isopropanol solution, stir for 30 min by magnetic force, and then add 50 mL of 90% isopropanol Isopropanol solution, continue to stir for 10min. The sample was transferred to a Buchner funnel and washed with 90% isopropanol until there was no Cl- (checked with 0.1 mol / L silver nitrate). Then transfer the sample into a 500mL beaker, add distilled water to 300mL, boil in water bath for 20min, add 2 drops of phenolphthalein, and titrate with 0.1mol / L NaOH to pink while hot.

[0044] The formula for calculating degree of substitution (DS) is as follows:

[0045]

[0046] A: the amount of substance that consumes 0.1mol / L NaOH standard solution for every gram of sodium starch octenyl succinate (SSOS), mmol; ...

Embodiment 2

[0047] Embodiment 2, a kind of production method of potato octenyl starch succinate, carry out following steps successively:

[0048] 1. Potato starch and water are mixed into an emulsion under the action of a constant temperature magnetic stirrer, and potato starch accounts for 30% of the total weight of the emulsion; the reaction temperature is 30°C, and the stirring speed is 100r / min;

[0049] 2. Adjust the pH value of the above-mentioned emulsion to 7.5 by using sodium hydroxide with a weight concentration of 3%;

[0050] 3. Dilute octenyl succinic anhydride with absolute ethanol, and the volume ratio of absolute ethanol to octenyl succinic anhydride is 5 times;

[0051] 4. The diluted octenyl succinic anhydride obtained in step 3) is mixed with the emulsion obtained in step 2) to form a reaction system, and the weight ratio of the diluted octenyl succinic anhydride to the potato starch in the emulsion is 3% ; Add a NaOH solution with a weight concentration of 3% to maint...

Embodiment 3

[0054] Embodiment 3, a kind of production method of potato octenyl starch succinate, carries out following steps successively:

[0055] 1. Potato starch and water are mixed into an emulsion under the action of a constant temperature magnetic stirrer, and potato starch accounts for 35% of the total weight of the emulsion; the reaction temperature is 35°C, and the stirring speed is 100r / min;

[0056] 2. Adjust the pH value of the above-mentioned emulsion to 8.0 by using sodium hydroxide with a weight concentration of 3%;

[0057] 3. Dilute octenyl succinic anhydride with absolute ethanol, and the volume ratio of absolute ethanol to octenyl succinic anhydride is 5 times;

[0058] 4. The diluted octenyl succinic anhydride obtained in step 3) is mixed with the emulsion obtained in step 2) to form a reaction system, and the weight ratio of the diluted octenyl succinic anhydride to the potato starch in the emulsion is 3% ; Add a NaOH solution with a weight concentration of 3% to mai...

Abstract

The invention discloses a manufacturing method of octal-olefin succinic starch ester, which comprises the following steps: 1) blending potato starch and water in the thermostatic magnetic stirrer into emulsion; 2) adopting 3% sodium hydroxide to adjust the pH value of emulsion to 7.5-8.0; 3) adopting anhydrous alcohol to dilute octal-olefin succinic anhydride; 4) blending the diluted octal-olefin succinic anhydride and emulsion phase in the step 2) to form reacting system; adding 3% NaOH solution to maintain the pH value of reacting system; reacting 2-4h; 5) using 2mol / L alcaine to adjust the pH value to 6.4-6.6; washing through water and 70% alcohol separately; drying; grinding.

Description

technical field [0001] The invention relates to the field of food chemistry, in particular to a production method of starch octenyl succinate. Background technique [0002] Starch Octenyl Succinate (Starch Octenyl Succinate), also known as Starch Sodium Octenyl Succinate (SSOS), octenyl succinate starch, octenyl succinate starch, pure glue. It is an esterification product produced by starch or its derivatives and octenyl succinic anhydride (OSA) under alkaline or weak alkaline conditions, and is often prepared in the form of sodium salt during production. [0003] The raw materials used in the preparation of starch octenyl succinate can be different kinds of native starch, acid-modified starch, dextrin and other derivatives. Among the numerous starch alkenyl succinate products, only modified starch produced by treatment with octenyl succinic anhydride was approved by the US Food and Drug Administration (FDA) in 1972 as a food additive. [0004] Starch octenyl succinate is...
