The influence of palm oil replacement with a monoglyceride-palm oil-water gel (hydrogel) on physical properties and acrylamide content of a low fat short dough pastry was studied. The effect of the incorporation of the hydrogel was monitored during storage by assessing moisture, firmness, proton density/mobility using magnetic resonance imaging (MRI) and acrylamide content. The use of hydrogel allowed the lipid content of pastries to be reduced without affecting their moisture and crumb firmness. However, the hydrogel containing pastries showed a more crunchy crust, higher acrylamide content and a higher tendency to staling. As assessed by MRI, these results were ascribable to the development of a peculiar system morphology promoted by hydrogel incorporation in the food matrix.

Abstract

The influence of palm oil replacement with a monoglyceride-palm oil-water gel (hydrogel) on physical properties and acrylamide content of a low fat short dough pastry was studied. The effect of the incorporation of the hydrogel was monitored during storage by assessing moisture, firmness, proton density/mobility using magnetic resonance imaging (MRI) and acrylamide content. The use of hydrogel allowed the lipid content of pastries to be reduced without affecting their moisture and crumb firmness. However, the hydrogel containing pastries showed a more crunchy crust, higher acrylamide content and a higher tendency to staling. As assessed by MRI, these results were ascribable to the development of a peculiar system morphology promoted by hydrogel incorporation in the food matrix.
