Unveiling the Unique World of Waxy Starch: Properties, Production, and Applications
Waxy starch, derived from sources like corn, rice, and potato, boasts unique properties that distinguish it from other starch types. With an exceptionally high percentage of amylopectin and minimal amylose, waxy starch exhibits a dense and highly-ordered molecular structure. This distinctive composition imparts resistance to gelatinization when subjected to heat.
The Distinctive Properties of Waxy Starch
Resilient Against Gelatinization
The highly branched molecular structure of waxy starch renders it resistant to gelatinization, standing out as a starch type that withstands heat-induced breakdown and retrogradation.
With a high viscosity, waxy starch emerges as a premier thickening agent, finding applications across various industries.
Shear Stability Excellence
Waxy starch showcases exceptional resistance to shear forces, making it an ideal ingredient for high-shear applications where stability is paramount.
Notably transparent, waxy starch finds favor in applications where clarity is a critical attribute.
Crafting Waxy Starch: From Source to Product
Selective Breeding Magic
The production journey of waxy starch begins with selectively breeding plants that yield high amylopectin and low amylose levels. After harvesting, the starch undergoes extraction and purification processes to ensure purity.
