The main physicochemical characteristics of the HPP-treated juice did not show significant differences, as presented in Table 2. The efficiency of HPP treatments in preservation of fruit juices without modifying basic composition has been documented. studied the quality and shelf life of HPP-treated Valencia and Navel orange juices and compared them with fresh and thermally pasteurised juices. The juices were pressure processed at 600 MPa and 20 C for 60 s and stored at 4 and 10 C for up to 12 weeks. Generally, basic juice quality attributes, such as total soluble solids, viscosity, titratable acid content, alcohol insoluble acids, browning index and colour, were not significantly affected by HPP treatments. investigated the impact of HPP processing of blueberry juice at different pressures and treatment times on different physicochemical properties such as pH, soluble solids and colour. The pressures varied from 200 to 600 MPa, while the times ranged from 5 to 15 min. They found not significant changes for pH and soluble solids content in the HPPprocessed juice. reported no significant variation in pH, Brix and titratable acid of HPP-treated pomegranate juice at 350e550 MPa for 30e150 s. In agreement with all these reports, physicochemical characteristics of the HPP-treated juice in this project remained significantly unaffected.
