Production of starch nanoparticles using normal maize starch via heat-moisture treatment under mildly acidic conditions and homogenization

Water chestnut starch: extraction, chemical composition, properties, modifications, and application concerns

“…Numerous methods have been reported for the preparation of starch nanoparticles (SNPs), such as acid hydrolysis, enzymatic hydrolysis, nanoprecipitation, ultrasonication, physical methods including reactive extrusion, high-pressure homogenization, stirred media milling and gamma irradiation, and the combination of methods such as heat-moisture treatment (HMT) and homogenization under mild acidic conditions as well as HMT under mild acidic conditions. [138][139][140][141][142][143] The preparation of SNPs by physical methods is more advantageous compared to other chemical methods given that it is safer and more environment friendly. A combination of nanoprecipitation and ultrasonication acts is considered a simple, reliable, effective and environment-friendly method, which involves the slow addition of a dilute solution of starch to a solvent, and then breaking of the covalent bonds of starch due to the strong shear forces or mechanical forces of sound waves.…”

A comprehensive review of polysaccharide-based bionanocomposites for food packaging applications

“…Starch nanocrystals have also been prepared combining cross-linking and high-pressure homogenization [26]. Another combination of homogenization and heat moisture developed nanocrystals yielding 80% final product with a diameter of 50 nm [15,27].…”

Effect of ultrasound on the physical properties and processing of major biopolymers—a review

“…As a contemporary approach to treatment, it is fast, 24 time and energy-efficient, 24 highly selective in action, 24 useful in variegated reaction systems, 25 and almost free from toxic chemicals, giving products suitable especially for biological and pharmaceutical applications. Compared to other popular treatment approaches such as homogenization, 26 enzymatic treatment, 10 gamma irradiation, 27 etc. , ultrasonication provides better control, and the desired property is improved drastically.…”
