“…The absorbance bands at 1330, 1405, and 1595 cm −1 may be due to the vibration due to amide (−CN−), amine (−N−H), and some carbonyl (−CO−) groups . 37–39 The increase in the transmittance at the observed characteristic peaks may be attributed to the microwave-induced variation in the –C−H stretching and number of −O−H, −CN−, and −CO− groups in the structure of chitin extracted from the microwave-treated NNR flour. These microwave-induced variations in the structure of chitin may be correlated with those observed in SEM/EDX analysis.…”

Chitin, a cell wall polysaccharide, extracted from Nelumbo nucifera rhizome (NNR), was subjected to microwave treatment to modify its physical and functional characteristics. The NNR flour was irradiated at different levels of the microwave treatment period (1, 2, 3, 4, and 5 min). Chitin was extracted from the native and microwave-treated samples and analyzed for physical and functional characteristics. The microwave treatment resulted in some variations in the extract yield, structure, morphology, and composition of chitin that were directly correlated with its functional properties. Regression analysis of the data showed a significant ( p < 0.05) time-dependent linear decrease in extract yield, polynomial decrease in water-holding and swelling capacities, an exponential increase in oil holding, and an exponential decrease in iron-binding capacity of chitin extracted from microwave-treated flour. These variations in the studied functional properties may be due to microwave-induced hydrolytic degradation of chitin, structural rearrangements, and exposure of some lipophilic functional groups on the surface of chitin. The data would be a valuable contribution to the literature regarding microwave-induced modification in physical and functional characteristics of chitin present in N. nucifera rhizome and other plant-based biomaterials of industrial importance.

“…Similarly, Jridi et al [5] reported the highest sulfate content in SPs from head while the lowest content was related SPs from the skin of Bullet tuna. A number studies have stated that the increase of sulfate content in sulfated polysaccharides could enhance its bioactivity [34] , [35] .…”

“…The molecular weight of all extracted SPs was lower than those reported by Jridi et al [5] , who extracted SPs from Bullet tuna ( Auxis Rochei ) by-products by enzymatic method. Souissi et al [35] extracted SPs from razor clam, Solen marginatus, and reported two major peaks at 1075 kDa and 237.9 kDa for the recovered SPs. It has been reported that the molecular weight of polysaccharides can be dependent on the extraction process, purification techniques, and deproteinization treatment [21] , [35] .…”

“…The first stage was in the temperature range of 33.2~163.6 • C, during which the weight loss rate reached 12.0%. The result might be attributed to the evaporation of the free water and bounding water to the polysaccharides [48][49][50]. The second stage occurred in the temperature range of 163.6~395.3 • C, during which the weight loss was the most serious.…”

In this study, polysaccharide–rich Nymphaea hybrid extracts (NHE) were obtained using the ultrasound-assisted cellulase extraction (UCE) method optimized by response surface methodology (RSM). The structural properties and thermal stability of NHE were characterized by Fourier-transform infrared (FT–IR), high–performance liquid chromatography (HPLC) and thermogravimetry–derivative thermogravimetry (TG–DTG) analysis, respectively. Moreover, the bioactivities of NHE, including the antioxidant, anti–inflammatory, whitening and scratch healing activities were evaluated by different in vitro assays. NHE conveyed a good ability to scavenge against the 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radicals and inhibit the hyaluronidase activity. NHE can effectively protect the HaCaT cells against oxidative damage by inhibiting the intracellular reactive oxygen species (ROS) production in the H2O2 stimulation assays and promoting the proliferation and migration in the scratch assays. In addition, NHE was proven to inhibit melanin production in B16 cells. Collectively, the above results seem to be the evidence needed to promote the potential of NHE to be regarded as a new functional raw material in the cosmetics or food industries.
