What is Sodium Starch Octenylsuccinate?
Sodium starch octenylsuccinate, commonly named OSA-starch or SSOS, is a food additive derived from natural starch that has been chemically modified to enhance its functional properties. Sodium starch octenylsuccinate is produced by esterifying starch with octenylsuccinic anhydride under alkaline conditions. The process involves attaching hydrophobic octenyl groups to the hydrophilic starch molecule, creating an amphiphilic compound with both water-loving and oil-loving properties. This unique chemical structure gives SSOS its valuable emulsifying and stabilizing capabilities. This modification imparts both hydrophilic and hydrophobic properties to the starch, making it an excellent emulsifier and stabilizer. Its unique characteristics include:
- Excellent emulsion stability
- Resistance to high temperatures and acid conditions
- Film-forming capabilities
- High digestibility
- Low viscosity in solution
These properties make it invaluable in applications ranging from beverages and salad dressings to pharmaceutical coatings and cosmetic formulations. According to the U.S. Food and Drug Administration (FDA), sodium starch octenylsuccinate is approved to be used in the food and pharmaceutical industries.

Manufacturing Process of Sodium Starch Octenylsuccinate
The production of sodium starch octenylsuccinate involves the chemical modification of natural starches through esterification with octenylsuccinic anhydride.
Raw Materials Selection
The manufacturing process begins with the careful selection of starch sources. While corn starch is most commonly used due to its abundance and cost-effectiveness, other sources such as potato, tapioca, rice, or wheat starch may also serve as suitable starting materials.
Preparation of Starch Slurry
Once the appropriate starch source is selected, it undergoes preparation through the following steps:
- The native starch is dispersed in water to create a slurry with a concentration typically ranging from 30-40% solids.
- The pH of the slurry is adjusted to 7.5-8.5 using sodium hydroxide or sodium carbonate solution.
- The slurry is agitated continuously to ensure uniform dispersion and prevent sedimentation.
Esterification Reaction
The core of the SSOS manufacturing process involves the esterification reaction between starch and octenylsuccinic anhydride (OSA):
- The starch slurry temperature is controlled between 25-40°C to optimize reaction efficiency.
- Octenylsuccinic anhydride is added gradually to the slurry while maintaining the alkaline pH.
- The reaction proceeds for 6-24 hours, depending on the desired degree of substitution.
- Throughout the reaction, the pH is continuously monitored and maintained above 7.0 to prevent acid hydrolysis of the starch.
The chemical reaction involves the formation of an ester bond between the hydroxyl groups of the starch molecules and the anhydride groups of OSA. The degree of substitution (DS) typically ranges from 0.01 to 0.03, indicating that approximately 1-3% of the glucose units in the starch are modified.
Neutralization and Purification
Following the esterification reaction:
- The reaction mixture is neutralized using hydrochloric or sulfuric acid to a pH of 5.5-6.5.
- The sodium salt of octenylsuccinate starch is formed during this neutralization process.
- The modified starch undergoes multiple washing cycles to remove unreacted OSA, reaction by-products, and residual salts.
- Filtration or centrifugation techniques separate the purified product from the washing liquid.
Drying and Finishing
The final stages of the manufacturing process include:
The washed SSOS undergoes drying in drum dryers, spray dryers, or flash dryers to reduce the moisture content to below 12%.
The dried product is milled to achieve the desired particle size distribution.
Sieving removes any oversized particles to ensure product uniformity.
The final product is tested for quality parameters, including degree of substitution, viscosity, pH, moisture content, and microbiological purity.
Quality Control and Standardization
Quality control measures are implemented throughout the manufacturing process:
- In-process testing monitors reaction progress and ensures consistent modification levels.
- Final product testing verifies compliance with regulatory specifications, including:
o Degree of substitution within specified limits (typically 0.01-0.03)
o Octenyl Succinate groups, below 3g/100g
o Absence of pathogens and limited total microbial count
