Abstract:
... In this study, a novel method to clarify bayberry juice with composite clarifiers, chitosan and sodium alginate, has been designed. The optimal conditions were as follows: using chitosan 0.05 g/L first and then sodium alginate 0.05 g/L as composite clarifiers, standing for 2 h at 25 °C. The transmittance increased from 0.08 to 91.2% after treating by composite clarifiers, which was significantly h ...

Abstract:
... Detailed alginate molecular structural factors that modulated the texture of liquid core alginate beads were investigated. Under the same CaCl₂ concentration and contacting time, a higher bursting force can be generated from both high Mw and low M/G alginate beads.

Abstract:
... Nanofibre-supported forward osmosis (FO) membranes have gained popularity owing to their low structural parameters and high water flux. However, the nanofibrous membranes are less stable in long-term use, and their fouling behaviours with foulants in both feed solution (FS) and draw solution (DS) is less studied. This study developed a nanofibrous thin-film composite (TFC) FO membrane by designing ...

Abstract:
... In this work we study the electro-orientation (through electric birefringence experiments) of silver nanowires in polymer solutions eventually capable of forming gel networks. Information on the structure of the polymer solution is obtained by evaluating the electro-orientation of the nanowires. It is found that in presence of poly(ethylene oxide), Kerr’s law (birefringence proportional to the squ ...

Abstract:
... Starch based gels can be three-dimensional (3D) printed to fabricate food products. Previously, researchers added sodium alginate to the starch gel to enhance shape retention of corresponding printed products. This inspired us to hypothesize that xanthan gum, which is also a common thickening agent, might play a similar role in structuring starch composite gel in 3D printing experiments. The geome ...

Abstract:
... The effects of chain length and concentration of different fatty acids (stearic acid and lauric acid) on the structure, physicochemical, and functional properties of soy protein isolate/sodium alginate films were assessed. Fourier transform-infrared spectra confirmed the presence of fatty acids within the films. Increasing the fatty acid chain length or concentration affected their uniform distrib ...
