High hydrostatic pressure treatment provides persimmon good characteristics to formulate milk-based beverages with enhanced functionality

[EN] High hydrostatic pressure (HHP) applied during food processing can improve the retention of food quality attributes and nutritional values in comparison with pasteurization. Persimmon is a good source of bioactive compounds but it is a seasonal fruit that cannot be consumed throughout the year. The aim of this work was to compare the HHP and pasteurization treatments to formulate milk-based beverages containing this carotenoid rich ingredient and to evaluate their performance in these beverages. The carotenoid and tannin contents of persimmon were determined and the microstructure and rheology of the new milk-based persimmon beverages were examined. The results showed that HHP treatment favoured the release of carotenoids from the fruit matrix and precipitation of the tannins. The milk-based beverages prepared with the high-pressure persimmon presented the best rheological properties because unlike the untreated and pasteurized persimmon milk-based beverages, they did not form a gel-like structure or separate out.The authors wish to acknowledge the Spanish Ministry of Science and Innovation for the financial support (project AGL2011-30064-C02) and the Universitat Politecnica de Valencia (UPV) for the FPI grant given to Maria Hernandez Carrion.
