Effect of processing on physico-chemical characteristics of dietary fibre concentrates obtained from peach (Prunus persica L.) peel and pulp
In order to obtain rich dietary fibre concentrates with enhanced functional properties from peach peel and pulp, a treatment with ethanol (96% v/v) was performed previous to drying under 30. °C forced air convection for 7. h or under freeze drying. All the dietary fibre concentrates isolated were en...
