Abstract In this study, the effect and mechanism of myofibrillar protein (MP) gelation influenced by the hydration characteristic of three polysaccharides were studied through puncture test, paraffin section, SEM and Raman spectroscopy. The gel strength and water holding capability reflect that MP gelation only significantly improves until modified starch (MS) addition beyond 1.0%. The MS granule improves MP gel property through simply physical swelling effect. At gelatinization temperature, MS ...

Abstract The aim of this work is synthesis of magnetic and photoluminescence (PL) nano-fibers for detection of mercury (II) and lead (II) ions that are toxic and their detection are necessary. Prepared nanoparticles are controllable by external magnetic field, so their threat is much lesser than non-magnetic material. Firstly, iron nanoparticles were achieved with ball milling procedure and cellulose acetate (CA) nano-fibers were prepared by electro spinning procedure. Photoluminescence carbon d...

Abstract Micro/nano celluloses (MC)/NC) were magnetized by nanoγ-Fe2O3 into the nanoγ-Fe2O3@MC (NMMC) and nanoγ-Fe2O3@NC (NMMC) which oxidized to NMMCD and NMNCD dialdehydes for Schiff-base immobilization of urease as NMMCD/urease and NMMCD/urease. The relative enzyme-activity of the immobilized ureases were comparable with the free-urease, although 75% to 80% of the enzyme activity preserved for NMMCD/urease and NMNCD/urease after six cycles. The compared catalytic activities of the NMMCD/ureas...

Abstract In this paper, the composite beads were obtained by the encapsulation of a lamellar polysilicate magadiite in chitosan. The composite beads were tested as adsorbents for the removal of anionic Congo red (CR) and cationic methylene blue (MB) dyes. The obtained material was characterized by different methods such as XRD, SEM, TGA and zeta potential analysis. The adsorption mechanism of both dyes was supported by UV–vis and (FTIR) spectroscopy. The results reveal that the magadiite was imm...

Abstract A polysaccharide (PFPP) from purple passion fruit peel was optimally extracted, with the highest yield (10.05%, w/w) obtained under 35 °C extraction temperature, 240 W ultrasonic power, 65:1 mL/g liquid-to-solid ratio, 0.6% (w/v) ammonium oxalate, 30 min extraction time and pH 2.0. According to composition analyses, pectic PFPP and its fractions (PFPP-10, -15 and -20) were revealed as linear homogalacturonans interrupted by rhamnogalacturonan I in different lengths and extensities, wher...

Abstract In this study, an injectable and near-infrared (NIR) light-triggered ROS-degradable hyaluronic acid hydrogel platform was developed as localized delivery vehicle for photosensitizer protophorphyrin IX (PpIX) and anticancer drug doxorubicin (DOX), to achieve superior combined chemo-photodynamic therapy with light-tunable on-demand drug release. The in situ-forming hydrogel fabricated readily via the formation of dynamic covalent acylhydrazone bonds could efficiently prevent severe self-q...

Abstract Chemical modifications of cellulose fibers as pretreatment for cellulose nanofibrils (CNF) production have been investigated to improve the production process and the quality of obtained cellulosic nanomaterial. In this study, phosphorylation of cellulose fibers was optimized in anticipation of a future nanofibrillation. Different phosphate salts, namely NH4H2PO4, (NH4)2HPO4, Na2HPO4, NaH2PO4 and LiH2PO4 with different constants of solubility (Ks) were used to increase the efficiency of...

Abstract To ascertain the preliminary structural characteristics and biological activity of different fractions of polysaccharides from Sagittaria sagittifolia L. (SPCs) by ultrasonic assisted extraction (UAE), four new polysaccharides (SPC-60, SPC-70, SPC-80 and SPC-90) were successively fractionated by ethanol. The results implied that except for neutral sugar, four contained proteins and uronic acids in their structure, which were further confirmed by the ultraviolet and infrared spectra. Mol...

Abstract With the rising trend of incidence of cancers, effective therapies are urgently needed to control human malignancies. However, the chemotherapy drugs currently on the market cause serious side effects. Polysaccharides belong to a class of biomacromolecules, which have drawn considerable research interest over the years as it possess anti-cancer activities or can increase the efficacy of conventional chemotherapy drugs with fewer side effects. The antitumor activity of many polysaccharid...

Abstract The structural characterization and antioxidant activity of four Auricularia polysaccharides (A.cornea ACP)、A.auricula(AAP)、A.polytricha (APP) and M.fungus(MFP)) were studied in this paper. The results shown: polysaccharides of four Auricularia were mainly composed of mannose and galactose, all polysaccharides contained uronic acid and pyran ring structure with spectroscopy and NMR analysis. There was a significant difference in the total antioxidant capacity and APP was significantly h...
