Abstract/OtherAbstract:
In the present study, four high pressure (HP) treatments (100, 200, 300 and 400 MPa) during 9 minutes were evaluated to assess their effect on lipid fraction (fat soluble vitamins and fatty acid profile) of an orange juice-milk and a vegetables beverage. After HP treatment, non-significant changes in vitamin D2 and D3 contents were observed for both beverages. An increase in vitamin E activity was observed in HP beverages when pressures higher than 100 MPa were applied, mainly due to an increase in α-tocopherol content. Only a small reduction in fat content was found for the orange juice-milk but no changes were observed for vegetables beverage. A significant decrease in SFA levels was observed in HP (300-400 MPa) orange juice-milk. With regard to MUFA, a significant increase in oleic acid (C18:1) was found in both liquid foods. Non-significant differences in the PUFA profiles were observed after HP processing.
