“…The SGSS showed very high sugar content (97.66%). The sugar content was in accordance to the values of sulfated polysaccharides from squid (85.06%) (Abdelmalek et al, ) and red seaweed (85.6%) (Souza et al, ). Krichen et al () reported that total sugar contents of sulfated polysaccharides derived from skins of gray triggerfish and smooth hound are 73.25% and 72.5%, respectively.…”

“…SGSS exhibited an IC 50 value of 1.05 ± 0.31 mg/mL against DPPH radical, and this value was significantly ( p < 0.05) higher than that of BHA (0.11 ± 0.05 mg/mL). The free radical‐scavenging activity of the SGSS was higher compared to polysaccharides from other species such as squid ( Loligo vulgaris ) (Abdelmalek et al, ) and grass frog ( Rana chensinensis ) (Wang et al, ) which showed IC 50 values corresponding, respectively, to 19.42 and 1.69 mg/mL, respectively.…”

“…However, details studies on glycosaminoglycans from tissues of marine invertebrates, including crustaceans are rather limited. Recently, GAGs from several aquatic species such as ray ( Raja montagui ) (Ben Mansour et al, ), gray triggerfish ( Balistes capriscus ) and smooth hound ( Mustelus mustelus ) (Krichen et al, ), Pacific white shrimp ( Litopenaeus vannamei ) (Cahú et al, ), and squid ( Loligo vulgaris ) (Abdelmalek et al, ) have been extracted and characterized. In addition, GAGs have several applications in the medical, veterinary, pharmaceutical, and cosmetic field.…”

Sulfated glycosaminoglycans (SGSS) were extracted with enzymatic procedure from shrimp (Parapenaeus longirostris) byproducts and its biological properties were evaluated. The net yield of SGSS was found to be 7%. SGSS showed higher contents of sugar (97.66%) and uronic acid (46.48%) followed by sulfate (12%) and protein (1.37%). The monosaccharide composition revealed the presence of N‐acetylgalactosamine, glucuronic, and galacturonic acids. The physicochemical characteristics were determined using XRD, DSC, and FTIR analysis. The antioxidant potency of SGSS was evaluated by several different in vitro systems, including DPPH free radical scavenging (IC50 = 1.05 mg/mL), β‐Carotene bleaching inhibition (IC50 = 2.43 mg/mL), and iron‐chelating capacity (IC50 = 0.17 mg/mL). ACE‐inhibitory activity of SGSS was also investigated (IC50 = 1.74 mg/mL). Practical applications The sulfated glycosaminoglycans from shrimp shell (SGSS) possess significant antioxidant and antihypertensive properties and could be utilized as natural preservative ingredient in functional foods and in pharmaceutical industry.

“…The DPPH is a stable free radical, which has been widely agreed as a tool for estimating the free radical-scavenging activities of antioxidants [45,46]. DPPH radical scavenging activity of degraded pectin (PCU 1 , PCU 2 , PCU 3 ) was higher that PCU, but lower than that of ascorbic acid (Fig.…”

To minimize the serious environmental pollution caused by food byproducts, soybean curd residue was used as the substrate to ferment polysaccharides by Morchella esculenta. Water‐soluble crude polysaccharides (CMP) were purified by different gradient concentrations (30%, 60%, and 90%) of ethanol into three precipitation fractions. The experimental results indicated that the precipitated polysaccharides by the ethanol concentration of 60% (PMP) had the highest purity, containing rhamnose, arabinose, xylose, mannose, glucose, and galactose, with the molar ratio of 0.08:0.25:0.16:0.07:0.28:1.00. The physicochemical properties were revealed by SEM, AFM, FTIR, NMR, and Congo red test. Furthermore, the measurement of antioxidant activities in vitro demonstrated that PMP exhibited higher antioxidant capacities with the dose‐dependent manner than CMP and polysaccharides from unfermented soybean curd (USP). Overall, the results suggested that PMP had attractive functional activity which could be potentially utilized in functional food industries. Practical applications The polysaccharides from fungi sources are increasingly being used in functional food and pharmaceutical industry. In allusion to the problem of polysaccharides fermented by edible fungi, such as low yield, high cost, and hard to controllable. Soybean curd residue (SCR), a food waste, has been successfully used for the production of polysaccharides and graded ethanol was used to enhance polysaccharides production, lower the difficulty and homologous costs of purity. The results indicated that the purified polysaccharides displayed excellent antioxidant activities on scavenging DPPH and hydroxyl radicals. The outcomes of this work can provide technical support for comprehensive utilization of SCR and references for promotion and application of polysaccharides fermented from SCR via Morchella esculenta in food and medicine fields.
