“…36 The thermogram also exhibited an endothermic peak at about 323 °C related to the melting point of quercetin 47,48 with a shoulder at about 300 °C attributed to the starch degradation. 49 Instead, the DSC curve of the QUERC/CAA system showed a first broad endothermic peak corresponding to the dehydration, with a trend closely similar to that of CAA reported in a previous work up to about 280 °C. 34 Then, the second endothermic peak at about 327 °C was ascribed to the quercetin decomposition.…”

Quercetin, a flavonoid with outstanding antioxidant and antimicrobial properties, was adsorbed onto maize starch aerogel (MSA) and calcium alginate aerogel (CAA) through supercritical carbon dioxide adsorption. The composite systems may be applied in active packaging for food preservation. Supercritical adsorption experiments were performed at 180 bar and 40 and 60 °C. They showed that the higher amount of charged quercetin was obtained at 60 °C onto CAA as support. Field emission scanning electron microscopy (FESEM), Fourier transform infrared (FTIR) spectroscopy, X-ray diffractometry (XRD), specific surface area (SSA) determination, and differential scanning calorimetry (DSC) were used to characterize the composite systems. In vitro dissolution tests were also performed to study the possibility of employing quercetin adsorbed onto MSA and CAA as an active layer in food packaging.

Corn starch and citric acid, two low-cost and abundant materials, were used for establishing a novel screen printable hydrogel for printed electronics applications.Corn starch was modified with citric acid by melt-blending, the so obtained thermoplastic starch was ground to powder and added to a water-starch suspension. Ultrasonication was used to prepare hydrogels of different citric acid concentrations.The most promising hydrogel contained 10 % citric acid by weight, provided an ionic conductivity of (2.30 ± 0.07) mS•cm -1 and appropriate rheological properties for screen and stencil printing. The hydrogel shows superb printability and prolonged stability against degradation. The corn starch hydrogel was used as printable gel polymer electrolyte in fully printed supercapacitors. The specific capacitance of the printed supercapacitor reached 54 F•g -1 . The printable hydrogel polymer electrolyte is easy to produce without in-depth chemical knowledge, is based on widely used and non-toxic materials and may be used as a functional layer in other printed electronics applications such as printed batteries.
