“…As a result, β‐carotene endures rapid discoloration due to the oxidation and splits down into parts leading to the loss of chromophore of the system and specific orange color that is examined spectrophotometrically. Thus, the natural antioxidant protects the β‐carotene from bleaching by neutralizing the free radicals (Bouaziz et al., 2016; Jridi et al., 2019; Li, Li, & Zhou, 2007). Therefore, it is thought to be a good model for peroxidation of membrane‐based lipid.…”

“…However, all FSG samples exhibited lower inhibition rate of β‐carotene decoloration than BHA. Among all samples, UAE‐FSG exhibited more potential to prevent β‐carotene from bleaching by donating relatively more hydrogen atoms to peroxyl radicals of linoleic acid (Jridi et al., 2019). Several reports described the positive correlation between the antioxidant activity and molecular weight (Jridi et al., 2019; Li et al., 2007).…”

Several reports described the positive correlation between the antioxidant activity and molecular weight (Jridi et al., 2019; Li et al., 2007). MAE‐FSG and AAE‐FSG showed comparatively weak inhibition rate toward linoleic hydroperoxyl, credited to their high molecular weight with a more compact structure, resulting in stronger intramolecular hydrogen bond and less bioactivity (Jaballi et al., 2019).…”

Four extraction techniques (that is, hot water extraction [HWE], alkaline-acidic extraction [AAE], ultrasound assisted extraction [UAE], and microwave assisted extraction [MAE]) were compared for flaxseed gum extraction and their influence on the yield, purity, structural characterization (monosaccharide composition, molecular weight distribution, and microstructure by transmission electron microscope), and antioxidant activity (in terms of scavenging ability of 2,2diphenyl-1-picrylhydrazyl [DPPH], 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid [ABTS], and reducing power) was investigated. The HWE achieved higher yield (8.96%) than UAE (7.84%) followed by MAE (7.01%) and AAE (6.44%). Moreover, the four flaxseed gum (FSG) samples exhibited the identical monosaccharide composition, but slight difference was observed in the content, whereas the molecular weight ratios exhibited significant difference. All samples displayed concentration-dependent manner for all antioxidant assays. UAE-FSG showed significant higher scavenging ability on DPPH free radical, ABTS free radical, reducing power, and β-carotene bleaching assay followed by HWE-FSG, MAE-FSG, and AAE-FSG. Overall results showed that UAE was favorable to the purity of FSG, whereas HWE was more advantageous to improve the extraction yield and facile as it requires no special equipment.

“…Sulfated polysaccharides are highly complex and heterogeneous polymers found in different organisms, which generally have antioxidant actions on ROS (Costa et al, 2010;Alencar et al, 2019). Due to the presence of sulfate radicals, they donate electrons and exercise reducing power (Jridi et al, 2019). In animals (vertebrates and invertebrates), such compounds are found in the form of glycosaminoglycans (GAGs) (Jridi et al, 2019) and play important biological roles in living organisms (Valcarcel, Novoa-Carballal, Pérez-Martín, Reis, & Vázquez, 2017).…”

The study aimed to evaluate the in vitro antioxidant action of glycosaminoglycans (GAGs) from the skin of Oreochromis niloticus, and to determine their ideal concentration to supplement the sperm freezing medium of Prochilodus brevis. In experiment 1, the in vitro antioxidant properties of GAGs were verified through the analysis of DPPH, chelating ferrous ability, and total antioxidant capacity. In experiment 2, milt pools were formed, which were frozen in solution supplemented or not with different GAGs concentrations: 0 (control), 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5, or 5.0 mg mL-1 (total of 10 treatments). The samples were evaluated for membrane integrity, DNA integrity, sperm morphology, and sperm kinetics. The results of experiment 1 showed that the GAGs exhibited, with the increase of the concentration, significant antioxidant action, for all the evaluated tests, mainly in the chelating ferrous ability. In experiment 2, it was observed that the increase of GAGs concentration decreased kinetic parameters (P < 0.05), however, the control and 0.5 mg mL-1 GAGs concentration showed similar results. For the other parameters (membrane integrity, DNA integrity, and sperm morphology), there was no decrease in results with the increase of GAGs concentration. In conclusion, GAGs extracted from O. niloticus skin have antioxidant action, and the concentration of 0.5 mg mL-1 was the most adequate to supplement the P. brevis sperm-freezing medium.

“…Regarding its in vitro bioactivities, there are extensive reports of antioxidant activity [22,23], and one promising, but yet to be followed up on, antifungal discovery [24]. Antimicrobial potential of algal sulphated polysaccharides remains unexplored, but when obtained from other marine sources, such as fish skin and muscle, they have exhibited potent antimicrobial activities [25,26]. Aqueous solid-liquid extractions followed by ethanol precipitation and separation of said precipitate have previously provided a porphyran-rich extract with confirmed bioactivities [24].…”

Poultry Shelf-Life Enhancing Potential of Nanofibers and Nanoparticles Containing Porphyra dioica Extracts

Aqueous extracts of commercially available red macroalgae Porphyra dioica were integrated as inner coatings of food-grade polypropylene (PP) films through use of electrospinning and electrospraying technologies. Two coating formulations (A = 5 wt% P. dioica extract and 7.5 wt% polyvinyl alcohol (PVA); B = 1 wt% P. dioica extract, 1 wt% PVA, and 17% gelatine) were evaluated as to their capacity to delay spoilage of minced chicken breasts, through monitoring of microbial growth (total mesophile aerobic colony counts), colour stability, lipid oxidation (thiobarbituric acid reactive substances (TBARS)), and sensory analysis over a 4-day refrigerated storage. Scanning electron microscopy (SEM) imaging revealed an increased nanofiber and nanoparticle density on extract-enriched fibers, without compromise to their morphology or the homogeneity of the coatings. Total microbial counts on coating B samples was significantly (p < 0.001) reduced compared to uncoated plastic wraps. The coated samples also exhibited fewer colour degradation, though the coatings did not differ substantially from uncoated plastic wrap. Sensory analysis test subjects successfully distinguished the raw samples based on their treatment and gave a positive approval rating (66.7%) to the extract-enriched coatings when asked about edibility post storage.
