What Is E1404 Modified Starch? Manufacturing Process, Applications and Price Guide
E1404 modified starch, also known as oxidized starch, is a type of starch that undergoes controlled oxidation to modify its physicochemical and functional properties. Depending on the intended application, it can be manufactured from different botanical sources, including cassava (tapioca), corn, and potato starch.
Oxidized starch is used in various industrial formulations because its viscosity, film-forming properties, and processing characteristics can be tailored to specific requirements.
In this article, we explain what E1404 is, how it is manufactured, its major applications, and the key factors that influence its market price.

1. What Is E1404 Modified Starch?
E1404 is the international food additive code commonly used for oxidized starch.
Oxidized starch is produced by treating native starch with a suitable oxidizing agent under controlled conditions. This treatment modifies some of the chemical groups in the starch molecules and may alter their molecular structure.
During oxidation, some hydroxyl groups can be converted into carbonyl and carboxyl groups. Depending on the processing conditions, molecular chains may also undergo changes that affect viscosity and other functional properties.
Compared with native starch, oxidized starch can offer characteristics that are better suited to selected industrial applications, particularly those requiring controlled viscosity and film formation.
Common raw materials used to manufacture E1404 include:
- Cassava starch, also known as tapioca starch.
- Corn starch.
- Potato starch.
- Other suitable botanical starch sources.
The final product’s performance depends on its raw material, manufacturing process, oxidation level, and quality specifications.
2. Key Properties of E1404 Oxidized Starch
E1404 is valued for its adjustable functional properties in a range of industrial formulations.
2.1. Adjustable Viscosity
Oxidation can reduce starch molecular weight and modify the viscosity of starch paste. This can be useful in applications that require controlled flow, spreading, or coating performance.
2.2. Film-Forming Properties
Certain oxidized starch grades can form relatively uniform films after gelatinization and drying. This characteristic can be beneficial in paper manufacturing, textile processing, and selected surface-coating applications.
2.3. Improved Processing Characteristics
Depending on the formulation, oxidized starch can support more uniform distribution across a material’s surface and help improve processing performance in coating, sizing, or bonding applications.
2.4. Formulation Compatibility
E1404 can be incorporated into suitable formulations with other ingredients to achieve the desired performance. Compatibility should be evaluated under actual operating conditions because pH, temperature, formulation composition, and processing methods can affect the results.
2.5. Performance Depends on the Starch Source
Oxidized cassava, corn, and potato starch may differ in viscosity, film formation, and processing behavior. Buyers should therefore select products based on technical specifications and application testing rather than relying solely on the E1404 code.
3. E1404 Modified Starch Manufacturing Process
The manufacturing process for oxidized starch involves several controlled stages to ensure consistent quality and suitability for the intended application.
Step 1: Raw Material Selection
The process begins with a suitable starch source, such as cassava, corn, or potato starch.
Incoming materials are evaluated for relevant quality characteristics, including moisture content, purity, appearance, and consistency.
Step 2: Starch Slurry Preparation
The starch is dispersed in water to prepare a slurry with a concentration appropriate for the production system.
Proper dispersion helps maintain uniform processing conditions throughout the subsequent modification stage.
Step 3: Controlled Oxidation
The starch slurry is treated with a suitable oxidizing agent under controlled manufacturing conditions.
This treatment changes part of the starch’s chemical structure and can modify its viscosity, film-forming characteristics, and other functional properties.
The oxidizing agent, processing conditions, and degree of oxidation must be selected according to the manufacturing technology, product specifications, and applicable safety requirements.
Step 4: Reaction Control and Termination
Once the target product characteristics have been achieved, the reaction is terminated and the material is processed to meet the required specifications.
Relevant control parameters may include viscosity, pH, oxidation level, and other product-specific quality indicators.
Step 5: Separation, Washing, and Purification
The modified starch is separated from the liquid phase. Washing and purification may be used to remove unwanted soluble components and help ensure that the final product meets the relevant quality requirements.
Step 6: Drying and Milling
The starch is dried to the specified moisture level and then milled or processed to obtain a suitable particle size for its intended application.
Step 7: Quality Testing and Packaging
The finished product undergoes quality testing before packaging.
Depending on its intended use, quality parameters may include:
- Moisture content.
- pH.
- Viscosity.
- Whiteness and color.
- Gelatinization characteristics.
- Degree of oxidation.
- Applicable purity and safety parameters.
Products that meet the required specifications are packaged, stored, and transported under suitable conditions.
Note: Actual operating parameters depend on the manufacturer’s technology, equipment, raw materials, and product specifications.
4. Applications of E1404 Oxidized Starch
Due to its adjustable viscosity and film-forming characteristics, E1404 can be considered for several industrial applications.
4.1. Paper Manufacturing
Oxidized starch can be used as a surface-sizing agent or as a component in selected paper-coating formulations.
Potential benefits include:
- Supporting improved paper surface strength.
- Contributing to ink holdout and print quality in suitable formulations.
- Helping control surface characteristics.
- Improving the processing properties of certain coating systems.
Actual performance depends on the paper grade, manufacturing process, and formulation.
4.2. Textile Industry
Oxidized starch may be used in selected textile-sizing formulations to form a film around yarns and support subsequent processing operations.
Product selection should consider the fiber type, film strength, desizing requirements, and operating conditions of the textile mill.
4.3. Adhesives and Industrial Binders
Certain oxidized starch grades can be used in starch-based adhesives and other industrial bonding formulations.
Depending on the application, they may help adjust viscosity, adhesive spreading, and film formation.
Bond strength and overall performance should be evaluated using the actual materials and production conditions.
4.4. Food Processing
Oxidized starch may be used as a food additive in applications where its use is permitted and where the product complies with the applicable food-grade requirements.
Depending on the formulation, it may contribute to viscosity control, texture, or film formation.
Manufacturers must verify the applicable regulations in their target markets before using E1404 in food products. Industrial-grade oxidized starch should not automatically be considered suitable for food applications.
4.5. Other Industrial Applications
Depending on its technical properties, E1404 may also be evaluated for selected coating, surface-treatment, and material-processing formulations.
Its suitability should be confirmed through product specifications and application testing.
5. E1404 Oxidized Starch vs. Native Starch
| Feature | Native Starch | E1404 Oxidized Starch |
|---|---|---|
| Chemical structure | Naturally occurring starch structure | Chemically modified through oxidation |
| Viscosity | Depends on the starch source and gelatinization conditions | Can be adjusted through the modification process |
| Film formation | Depends on the starch source and application | May suit formulations requiring specific film properties |
| Applications | Food processing and various industries | Paper, textiles, adhesives, and other suitable applications |
| Cost | Depends on raw materials and quality | Depends on raw materials, processing, and specifications |
