Preparation and Characterization of Konjac Glucomannan Gel
Applied Mechanics and Materials, 2011Konjac glucomannan (KGM) gel was prepared by alkali catalyzed in aqueous solutions. The structure of the KGM gel was characterized by Fourier transform infrared (FTIR) spectroscopy and wide angle X-ray diffraction (WAXRD). The gel point of KGM solutions was determined by steady state fluorescence method and It was observed that the gel point of the KGM

Rheological properties of mixed gels of konjac glucomannan (KGM) with different molecular weights and kappa-carrageenan (CAR) were studied by a dynamic viscoelastic measurement and a tensile testing. Both storage and loss moduli for sol state mixtures containing higher molecular weight of KGM were higher.

Lipase‐catalyzed modification of konjac glucomannan
Journal of Applied Polymer Science, 2006AbstractRegioselective acylation of konjac glucomannan (KGM) with vinyl acetate in a solvent‐free system was successfully performed using Novozym 435 as a biocatalyst. The degree of substitution (DS) of the modified KGM was used to evaluate the extent of acylation.

Characterization and property of palmitoylated konjac glucomannan
Wuhan University Journal of Natural Sciences, 1997Various degrees of paimitoylated konjac glucomannan (PKGM) are prepared by heterogeneous method. Differential thermal analysis (DTA) thermographs show PKGM having certain degree of substitution (DS) gave a new crystalline peak at higher temperature. And PKGM having higher DS only shows the new crystalline state.

Deacetylation of konjac glucomannan by mechanochemical treatment
Journal of Applied Polymer Science, 2008AbstractThis article presents the experimental results on deacetylation of a konjac glucomannan (KGM) powder with alkali in mechanochemical (MC) treatment by a dry vibrating mill. It is indicated that the acetyl group of the KGM powder could be removed by means of the MC method.

Mixtures of konjac glucomannan and kappa carrageeean at temperatures above and below the melting point of the kappa carrageenan helix were studied by rheometry and calorimetry. The objective of the work was to investigate the effect of alkali deacetylation of the konjac glucomannan on the properties of the mixed gels.

The Research of Konjac Glucomannan Fracturing System
Advanced Materials Research, 2013Fracturing fluid was obtained by putting the organic borate and organic titanium crosslinkers into the base fluid of konjac glucomannan. The properties of the fracturing fluid were also discussed. The system was very stable until the temperature reach to 90°C.

Environmentally friendly food packaging has emerged as a viable strategy to replace traditional plastic films. In this study, eugenol Pickering emulsion was constructed with konjac glucomannan (KGM) and tragacanth gum (GT) as stabilizers, and was introduced into the KGM/chitosan (CS) composite film by electrostatic action to develop a new type of ...
