Abstract: Using Konjac Glucomannan and pigskin glue as experimental materials,when the different amount of Konjac gum added on pigskin glue that the changes of the moisture distribution and migration,the gel strength and microstructure were analyzed by using low field nuclear magnetic resonance( NMR),texture analyzer and scanning electron microscopy( SEM) to explore the interaction.The experimental results showed that when the Konjac gum addition was 0.5% ~0.7%,the transverse relaxation peak of the water distribution of the pigskin glue moves to the left,transforming part of free water to bound water,moreover,three distribution of water were similar with fresh meat on good texture and tissue state.And the gel strength was maximum by measuring texture,which was the strongest interaction at this time. By scanning electron microscopes,the pigskin glue surface microstructure of porous structure was decreased gradually with the addition of Konjac gum.It was completely filled to the hole of pigskin glue surfaces when added amount of Konjac gum was 0.5%.
