Corn starch systems as carriers for yerba mate (Ilex paraguariensis) antioxidants: Effect of mineral addition

Fortified Rice Starches: The Role of Hydrothermal Treatments in Zinc Entrapment

“…The native starch and the HMT treated starch presented an increase in relative crystallinity after fortification, as shown in other studies, while the ANN treated starch showed decreased relative crystallinity. The changes in relative crystallinity after zinc entrapment for the ANN and HMT modified samples, which did not present high zinc content, can be attributed to reaction conditions such as shearing and temperature (50 °C); the latter can provide conditions suitable for molecular mobility and mechanical stress.…”

“…Fortunately, modifications to starch can be used to overcome this drawback, thus increasing its applications and improving the nutritional characteristics of starch. For instance, the modification of starch can both improve resistant starch levels and enable the formation of complexes that have organic and inorganic components with increased bioavailability …”

Effect of High Hydrostatic Pressure, alkaline and combined treatments on corn starch granules metal binding: Structure, swelling behavior and thermal properties assessment

“…HPS was obtained by suspending 10 g/100 mL of the native corn starch in deionized water (Milli-Q, Millipore Inc. Bedford, MA, USA), this suspension was treated using a High Hydrostatic Pressure (HHP) Pilot Food Processor (Stansted Fluid Power LTD. Model FP 571000:9/2C, UK) operated under 400 MPa, for 35 min, at an initial vessel temperature of 38 • C and reaching a final process temperature of 40 • C. These conditions were selected based on different assays performed in the lab (data not published) and conditions applied in previous works (Deladino et al, 2015;Fernández et al, 2008;Teixeira et al, 2015).…”

“…Porosity of starch carriers was higher in HHP treated samples compared to the native starches, thus an increased exposed surface area suggested higher potential binding sites, which could be occupied by active compounds. The ability of these modified starch granules as carriers for small molecules of nutritional interest, such as oligoelements ions and antioxidant compounds has been successfully tested (Deladino et al, 2015;Fernández et al, 2008;Teixeira et al, 2015). The amount of yerba mate antioxidant compounds, an herbal aquous extract rich in chlorogenic acid (isomers and esters), caffeic acid and rutin, or metals ions that could be bound increased substantially over native starch with large differences in the incorporation level depending on the pressure treatment and ligand addition sequence (Deladino et al, 2015;Teixeira et al, 2015).…”

It was shown that adding ligands to previously HHP treated starch is less efficient than to bind them to starch during pressure treatments (Deladino et al, 2015).…”
