Starch Phosphorylation for Functional and Industrial Applications

Starch is an important determinant for the texture of§many foodstuffs, and it is widely used in industrial§applications as a thickener, stabilizer, gelling§agent, and adhesive. The effects of starch are§related to its gelatinization and retrogradation. The§demand for increased performance of applications§points out the limitations of starch. Modified§starches were developed to overcome these §shortcomings. The modification processes aim at§changing the properties and the integrity of the§starch granule, in order to modify its behavior in§terms of gelatinization, and retrogradation. In the§current research various types of starches (corn,§rice and potato), corn amylase and corn amylopectin§were phosphorylated, and their physicochemical§properties were investigated. Modified starch with§novel properties is anticipated to be used in many§functional foods and pharmaceuticals. Biodegradable§films were formulated from native and modified§starch, and their solubility s and biodegradable§properties were investigated. Successful application§of modified starch-based films in plastic§manufacturing provides a number of benefits including§clean environment, and cost savings.
