“…In the FT-IR spectrum for powders (control and experimental groups), a broad band at around 3400 cm −1 indicating O-H stretching vibration from polysaccharides, and two sharp peaks of C-H asymmetric/symmetric stretching vibration at 2920 cm −1 and 2850 cm −1 from the lipid content appeared, as shown in Figure 4a [35]. The absorption peak of the carbonyl C=O stretching at 1740 cm −1 was assumed to be due to the presence of polyphenol and flavonoid compounds such as rutin.…”

Carbon-neutral and eco-friendly biomass-based processes are recognized as a frontier technology for sustainable development. In particular, biopolymers are expected to replace petrochemical-based films that are widely used in food packaging. In this study, the fabrication conditions of functional (antioxidant and antibacterial) bioelastomers were investigated using by-products from the juice processing (experimental group) and freeze-dried whole fruit (control group). Bioelastomer was fabricated by a casting method in which polydimethylsiloxane (PDMS) was mixed with 25 or 50 wt% aronia powder (juice processing by-products and freeze-dried whole fruit). The mechanical properties of the bioelastomers were measured based on tensile strength and Young’s modulus. When the mixture contained 50 wt% aronia powder, the strength was not appropriate for the intended purpose. Next, the surface and chemical properties of the bioelastomer were analyzed; the addition of aronia powder did not significantly change these properties when compared to PDMS film (no aronia powder). However, the addition of aronia powder had a significant effect on antioxidant and antimicrobial activities and showed higher activity with 50 wt% than with 25 wt%. In particular, bioelastomers fabricated from aronia juice processing by-products exhibited approximately 1.4-fold lower and 1.5-fold higher antioxidant and antimicrobial activities, respectively, than the control group (bioelastomers fabricated from freeze-dried aronia powder).

“…The branches were multi-bifurcated, quasi-circular, and quasi-spherical, and the surface is smooth and non-porous. The morphology of Se-ESPS-B1 was similar to that of microcrystalline [38,41]. Meanwhile, the microscopic morphology of ESPS-B1 was sheet-like and rod-shaped, with a smooth surface and no bifurcation, which suggested that the interaction between ESPS-B1 molecules was strong and the binding was tight.…”

In order to obtain and explore selenide composed of selenium and polysaccharide, three parameters were selected to optimize the synthesis process of selenium-Euryale ferox Salisb. polysaccharide (Se-ESPS) by Box-Behnken design. Furthermore, ESPS-B1 separated from ESPS was selenitized to Se-ESPS-B1 by the optimal synthesis process, then the characterization, and antioxidant activity in vitro of Se-ESPS-B1 were explored. The result manifested that the Se content of Se-ESPS was (2.915 ± 0.03) mg/g according to the optimal synthesis process of Se-ESPS (reaction time at 5 h, reaction temperature at 81 ℃, weight ratio of Na2SeO3 to ESPS at 0.9 g/g). A series of detection results indicated that the characterizations of Se-ESPS-B1 were apparently distinguished from that of ESPS-B1. Moreover, the antioxidant experiments in vitro demonstrated that Se-ESPS-B1 could exert antioxidant activity by scavenging DPPH, ABTS,·OH, and increasing reduction ability. In conclusion, the synthesis process is an effective approach to harvest selenium-polysaccharide, and Se-ESPS-B1 may be utilized as a potential antioxidant or selenium nutritional supplement.

“…Sun et al [ 31 ] found that Se-polysaccharides from Se-enriched Pleurotus geesteranus with a molecular weight of 3.32 × 104 Da belonged to acidic polysaccharides with α- D -glucopyranoside bond, and there was a characteristic peak ascribing to Se–O–C stretching vibrations in their infrared spectrum. Structure of two Se-polysaccharides (SeTPS-1 and SeTPS-2) isolated from Se-enriched tea was characterized by GC, FT-IR, Congo red test, and NRM [ 54 ]. It was found that SeTPS-1 was composed of glucose and galactose while SeTPS-2 was composed of arabinose, glucose, galactose, and galacturonic acid.…”

“…It was found that SeTPS-1 was composed of glucose and galactose while SeTPS-2 was composed of arabinose, glucose, galactose, and galacturonic acid. Se was attached to polysaccharides backbone in the form of Se = O and O–Se–O, and two Se-polysaccharides were random coil conformations instead of triple-helix structures [ 54 ]. Se-enriched heteropolysaccharides with molecular weight of 4.13 × 10 6 Da were extracted from Se-enriched Grifola frondosa [ 55 ].…”
