Modified Starch

It is also called starch derivatives, which are produced by physically, chemically or enzymatically treating with native starch to change, strengthen or impair new properties by molecular cleavage, rearrangement or introduction of new substituent groups. There are numerous ways to modify food starch, such as cooking, hydrolysis, oxidation, bleaching, oxidation, esterification, etherification, crosslinking and etc.

Physically modification 1. Pre-gelatinization 2. Radiation treatment 3. Heat treatment

Chemically modification 1. Esterification: Acetylated starch , esterified with acetic anhydride or vinyl acetate. 2. Etherification: Hydroxypropyl starch , etherified with propylene oxide. 3. Acid treated starch , treated with inorganic acids. 4. Alkaline treated starch, treated with inorganic alkaline. 5. Bleached starch, dealt with hydrogen peroxide. 6. Oxidation: Oxidized starch, treated with sodium hypochlorite. 7. Emulsification: starch sodium Octenylsuccinate, esterified with octenyl succinic anhydride.

Modified Starch is a type of processed starch widely used as thickening agent, stabilizer or emulsifier in food production. As a thickening agent, stabilizer or emulsifier, Modified Starch can be used in a wide variety of industries including: food production, beverage, pharmaceutical, and various other industries.

In Food Production

Modified Starch is widely used as Thickeners, gelling agents, adhesives, emulsifiers and stabilizers in food production.

· As Thickening, film forming, stability, pasting properties: in rice product to improve mouthfeel and quality, reduce cooking time and extend shelf life.

· As Insurance agent, binder and excipients: in meat and aquatic product to improve texture, maintain moisture, .

In Beverage

Modified Starch is widely used as texture stabilizers, adsorbent and emulsifier in beverage.

· As texture stabilizers, adsorbent and emulsifier: in beverage industries to enhance flavor and improve mouthfeel.

In Pharmaceutical

Modified Starch is widely used as Excipients in Pharmaceutical.

· As Excipients: in tablets manufacturing to improve quality.

In Other Industries

Modified Starch is widely used as raw materials in various other industries.

· As raw materials: in paper-making industries to improve quality.
