Abstract:Strong hydrophilic group was introduced in the starch molecular by chemical reaction, greatly increasing water absorption properties and holding capacity. Reaction conditions for the production were determined as 10% of hydrogen peroxide amount, 60 ℃ of the reaction temperature, 3h of reaction time. The moistening performance of modified-starch humectants and traditional humectants were compared. The result showed that the moistening performance of modified-starch humectants was better than that of the traditional one.
