title: In vitro retardation of glucose diffusion with gum extracted from malva nut seeds produced in Thailand.
abstract: Mucilage of malva nut fruit has been used as traditional medicine in Thailand. Our laboratory has succeeded in extracting malva nut gum (MNG) from malva nut seeds by using alkaline-extraction method. The extract had higher gelling properties compared to water-extracted MNG. This research was aimed to investigate the effect of MNG on the retardation of glucose diffusion in in vitro dialysis processes. The results showed that alkaline-extracted MNG significantly (p<0.05) reduced glucose content in dialysate compared to control containing no dietary fibre. MNG at 1% (w/w) concentration was more effective than that of 0.5% (w/w) concentration. The mixture of MNG and guar gum significantly (p<0.05) reduced glucose in dialysate by 50-82% compared to that of control. In starch digestion process, the mixture of MNG and guar gum showed greater reduction of glucose (3-7 folds) in dialysate at 15-30min.
