Oxidized starch

Oxidized starch is a modified form of starch that has undergone a controlled oxidation process, typically using chemicals such as sodium hypochlorite or hydrogen peroxide. This modification enhances the starch’s functional properties, making it more versatile in various industrial applications. Oxidized starch is commonly used as a thickening agent, stabilizer, and emulsifier in industries like food processing, pharmaceuticals, textiles, and paper manufacturing. It can improve the texture, viscosity, and shelf life of products while offering enhanced binding and film-forming characteristics. The oxidation process also reduces the starch’s tendency to retrograde, making it ideal for use in products that require a consistent texture and performance over time.

1. Food Industry

• Thickening Agent: Oxidized starch is used as a thickener in soups, sauces, gravies, and puddings due to its enhanced viscosity and stability.
• Emulsifier: It helps in stabilizing emulsions in products like salad dressings, mayonnaise, and sauces.
• Sugar Coating: Used in confectionery for coating and providing a glossy finish to products like candies and coated nuts.
• Improving Texture: In bakery products, oxidized starch improves texture, mouthfeel, and shelf-life.
• Frozen Food: It is used in frozen food products to help maintain consistency after freezing and thawing.

2. Textile Industry

• Size Agent: In textiles, oxidized starch is used as a sizing agent to impart strength and smoothness to yarns and fabrics during the weaving process.
• Finishing Agent: It provides fabrics with a more durable finish and prevents them from becoming too stiff or brittle.

3. Paper and Pulp Industry

• Wet-End Additive: Oxidized starch is used in paper manufacturing, particularly as a wet-end additive to improve paper strength and printability.
• Coating: It helps in coating paper products for better surface quality and appearance.
• Paperboard Manufacturing: Used in the production of paperboard to enhance its strength and durability.

4. Adhesive Industry

• Glue and Adhesive: Oxidized starch is utilized in adhesives, particularly in the packaging and paper industries, due to its superior bonding strength.

5. Oil and Gas Industry

• Drilling Fluids: Oxidized starch is sometimes used as a component in drilling fluids to increase viscosity and control water loss during oil and gas drilling.

6. Agriculture

• Soil Stabilizer: In some agricultural applications, oxidized starch is used as a soil stabilizer to improve water retention and reduce erosion.

7. Biodegradable Plastics

• Eco-friendly Materials: Oxidized starch can be used in the production of biodegradable plastics as it contributes to the material’s biodegradability and enhances its mechanical properties.

8. Animal Feed

• Binder and Energy Source: It can also be used as a binder in animal feed formulations and provides a source of energy for livestock.
